1. Bayanin Samfur

The 19-217/S2C-AL1M2VY/3T is a surface-mount device (SMD) LED designed for modern electronic applications requiring reliable, compact, and efficient indicator lighting. This component utilizes AlGaInP (Aluminum Gallium Indium Phosphide) semiconductor technology to produce a brilliant orange light output. Its primary design goals are miniaturization, compatibility with automated assembly processes, and adherence to stringent environmental and safety standards.

The core advantages of this LED stem from its SMD package. It is significantly smaller than traditional lead-frame type LEDs, enabling higher component packing density on printed circuit boards (PCBs). This leads to reduced overall board size, minimized storage space requirements, and ultimately contributes to the development of smaller and lighter end-user equipment. The lightweight nature of the package makes it particularly suitable for miniature and portable applications where space and weight are critical constraints.

The target market for this product is broad, encompassing general electronics, consumer devices, and industrial equipment. It is engineered to meet the needs of designers looking for a dependable, RoHS-compliant, and halogen-free orange indicator solution that can be integrated using standard surface-mount technology (SMT) lines.

2.2 Sigogin Lantarki

Electrical characteristics define the operating limits and conditions for reliable performance.

• Forward Voltage (VF): The voltage drop across the LED when operating at the specified current. At IF=5mA, it ranges from a minimum of 1.70V to a maximum of 2.20V, with a tolerance of ±0.05V. This low forward voltage is advantageous for low-power and battery-operated devices. The voltage is also binned (codes 19 to 23).
• Reverse Voltage (VR): The maximum voltage that can be applied in the reverse direction without damaging the device. The absolute maximum rating is 5V.
• Reverse Current (IR): The leakage current when the maximum reverse voltage (5V) is applied. It has a maximum value of 10 µA.
• Forward Current (IF): The recommended continuous operating current is 25 mA.
• Peak Forward Current (IFP): For pulsed operation (duty cycle 1/10 at 1 kHz), the LED can handle a peak current of up to 60 mA.

2.3 Zazzabi da Matsakaicin Matsayi

3. Binning System Explanation

To ensure color and brightness consistency in production, LEDs are sorted into bins based on key parameters. This allows designers to select parts that meet specific application requirements.

3.1 Luminous Intensity Binning

LEDs are categorized into four bins (L1, L2, M1, M2) based on their measured luminous intensity at 5mA. This allows selection for applications requiring different brightness levels while maintaining predictable performance.

3.2 Dominant Wavelength Binning

4. Performance Curve Analysis

Duk da yake an ambaci takamaiman lanƙwan masu lanƙwasa a cikin takardar bayanai, ana iya bayyana abubuwan da suke nufi bisa ga daidaitattun halayen LED da kuma sigogin da aka bayar.

The Current vs. Voltage (I-V) curve would show the exponential relationship typical of a diode. The specified forward voltage range (1.7-2.2V at 5mA) indicates the "knee" of this curve. Operating significantly above 5mA would require a higher forward voltage, moving up the exponential slope. This underscores the importance of using a current-limiting resistor or constant-current driver, as a small increase in voltage can cause a large, potentially destructive increase in current.

The Luminous Intensity vs. Forward Current (L-I) curve is generally linear over a range. Operating at the maximum continuous current (25mA) would produce significantly higher light output than at the test current of 5mA, but it would also increase power dissipation and junction temperature, which must be managed through proper PCB thermal design.

The Temperature Dependence characteristics are critical. For AlGaInP LEDs, luminous intensity typically decreases as the junction temperature increases. While the exact derating curve is not provided, the wide operating temperature range (-40°C to +85°C) confirms the device's robustness. Designers must account for intensity drop in high-temperature environments. The forward voltage also has a negative temperature coefficient, meaning it decreases slightly as temperature rises.

The Spectral Distribution Curve ya nuna wani guda, kunkuntar koli mai tsakiya a kusa da 611 nm (na yau da kullun), tare da bandwidth na 17 nm yana ayyana faɗinsa. Wannan ya tabbatar da yanayin monochromatic na fitarwa, wanda ya dace da aikace-aikacen da ke buƙatar takamaiman launin orange mai cikakke.

5. Mechanical and Package Information

• Tsarin Kunshin: Zanen ya ƙayyade tsayi, faɗi, da tsayin jikin LED, da kuma girma da tazara na tashoshin da ake iya gyarawa (pad).
• Ƙirar Pad: Sawun ƙafar da ke kan PCB dole ne ya dace da shimfidar pad da aka ba da shawarar don tabbatar da ingantaccen gyarawa, kwanciyar hankali na injiniya, da yuwuwar ɓarkewar zafi.
• Gano Polarity: The datasheet drawing clearly indicates the anode and cathode terminals. Correct polarity is essential for device operation. Typically, one pad may be marked or shaped differently (e.g., a notch or a beveled corner on the LED package itself) to indicate the cathode.
• Material: The lens (resin) color is specified as "Water Clear," meaning the orange light is emitted through a transparent encapsulant, which contributes to the wide 120-degree viewing angle.

6. Soldering and Assembly Guidelines

Proper handling and soldering are crucial for reliability. The LED is supplied in moisture-resistant packaging (tape on reel) compatible with automatic pick-and-place equipment.

6.1 Reflow Soldering Parameters

A lead-free (Pb-free) reflow soldering profile is recommended. The profile includes:

• Pre-heating: Ramp from ambient to 150-200°C over 60-120 seconds.
• Soak/Reflow: Time above liquidus (217°C) should be 60-150 seconds. The peak temperature must not exceed 260°C, and the time at or above 255°C must be limited to a maximum of 30 seconds.
• Cooling: The maximum cooling rate should be 6°C per second.

Critical Note: Reflow soldering should not be performed more than two times on the same LED assembly to avoid thermal stress damage.

6.2 Storage and Moisture Sensitivity

The components are packaged in a moisture-barrier bag with desiccant.

• Before Opening: Store at ≤30°C and ≤90% Relative Humidity (RH).
• After Opening: The "floor life" (time components can be exposed to ambient factory air) is 1 year at ≤30°C and ≤60% RH. Unused parts should be resealed in moisture-proof packaging.
• Baking: If the desiccant indicates saturation or the storage time is exceeded, a bake at 60±5°C for 24 hours is required before reflow to prevent "popcorn" cracking during soldering.

6.3 Hand Soldering and Rework

Idan ake buƙatar sayar da hannu:

• Yi amfani da ƙarfe na ƙarfe tare da zazzabi mai zazzabi ≤350°C.
• Iyakance lokacin tuntuɓar zuwa ≤3 seconds kowace tasha.
• Yi amfani da ƙarfe tare da ƙimar wutar lantarki ≤25W.
• Ƙyale aƙalla tazarar 2-second tsakanin sayar da kowace tasha.

Ana ƙarfafa hana sake aiki. If absolutely unavoidable, a specialized double-head soldering iron must be used to simultaneously heat both terminals and lift the component without applying mechanical stress. The impact on LED characteristics must be verified after any rework.

7. Packaging and Ordering Information

The standard shipping package is an 8mm wide carrier tape wound on a 7-inch diameter reel. Each reel contains 3000 pieces.

The reel and carrier tape have specific dimensions provided in the datasheet drawings to ensure compatibility with automated assembly equipment.

The packaging label contains critical information for traceability and correct application:

• CPN: Customer's Product Number (if assigned).
• P/N: The manufacturer's part number (19-217/S2C-AL1M2VY/3T).
• QTY: Packing quantity (3000 pcs/reel).
• CAT: Luminous Intensity bin code (e.g., L1, M2).
• HUE: Dominant Wavelength bin code (e.g., D9, D11).
• REF: Forward Voltage bin code (e.g., 20, 22).
• LOT No: Manufacturing lot number for traceability.

8. Application Recommendations

8.2 Muhimman Abubuwan Zane-zane

1. Iyakancewar Halin Yanzu Wajibi Ne: An external current-limiting resistor must always be used in series with the LED. The forward voltage has tolerance and a negative temperature coefficient. A slight increase in supply voltage or a decrease in VF due to heating can cause a large, destructive current surge if not properly limited. The resistor value (R) is calculated as R = (V_supply - VF_LED) / I_desired.
2. Thermal Management: While the package is small, the 60mW maximum power dissipation must be respected. Operating at high currents (e.g., 25mA) generates heat. The PCB layout should provide adequate copper area around the LED pads to act as a heat sink, especially in high ambient temperature environments or when multiple LEDs are clustered.
3. ESD Precautions: Although rated for 2000V HBM, standard ESD handling procedures should be followed during assembly and handling to prevent latent damage.
4. Optical Design: The 120-degree viewing angle provides a very wide, diffuse emission pattern. For applications requiring a more focused beam, an external lens or light guide may be necessary.
