. Mechanical and Package Information

The LED uses a standard 2820 SMD package. The mechanical drawing specifies the physical dimensions in millimeters. Key features include the anode and cathode pad locations and the overall package height. The recommended soldering pad layout is provided to ensure proper mechanical attachment, electrical connection, and optimal thermal transfer from the LED's thermal pad to the PCB. Adhering to this land pattern is essential for reliability, especially under thermal cycling conditions experienced in automotive environments.

. Soldering and Assembly Guidelines

The device is rated for reflow soldering with a peak temperature of 260°C for a maximum of 30 seconds, as per the IPC/JEDEC J-STD-020 profile. The Moisture Sensitivity Level (MSL) is 2, meaning the components must be baked if exposed to ambient conditions for longer than one year before use. Following the recommended reflow profile and handling precautions is mandatory to prevent package cracking or solder joint defects.

. Packaging and Ordering Information

The LEDs are supplied on tape and reel for automated assembly. The packaging information details the reel dimensions, tape width, pocket spacing, and orientation of the components on the tape. The part number structure (e.g., 2820-C02001M-AM) encodes key attributes such as the package size (2820), color/chip type (C02001M), and series designation (AM). Ordering involves specifying the required bins for luminous flux, forward voltage, and chromaticity.

. Application Recommendations

.1 Typical Application Scenarios

The primary application is automotive lighting. This includes interior lighting (dome lights, map lights, ambient lighting), exterior signaling (center high-mount stop lights - CHMSL), and potentially some auxiliary lighting functions. Its AEC-Q102 qualification and sulfur resistance (Class A1) make it suitable for the harsh under-hood or exterior vehicle environment.

.2 Design Considerations

Driver Circuit:A constant-current driver is essential to maintain stable light output and prevent thermal runaway. The driver must be designed to accommodate the forward voltage bin range and provide adequate current limiting up to 350 mA.

Thermal Design:Effective thermal management is non-negotiable. The PCB should use thermal vias under the LED's thermal pad connected to a large copper plane or an external heatsink to minimize the temperature rise at the solder point (Ts). Always refer to the forward current derating curve.

Optical Design:The 120-degree viewing angle provides wide coverage. For focused applications, secondary optics (lenses, reflectors) will be required. The mechanical drawing provides the necessary dimensions for designing such optics.

ESD Protection:While the LED has a robust ESD rating of 8 kV (HBM), standard ESD handling precautions during assembly are still recommended.

. Technical Comparison and Differentiation

Compared to generic commercial-grade LEDs, the key differentiators of this series are its automotive-grade reliability certifications (AEC-Q102), explicit sulfur gas resistance testing (Class A1), and extended operating temperature range (-40°C to +125°C). The detailed binning structure for color and flux provides a level of consistency required for automotive applications where multiple LEDs are used in a single assembly. The combination of good luminous efficacy (80 lm at 200mA equates to ~133 lm/W considering ~0.6W input) and a wide viewing angle in a compact package offers a balanced solution for space and performance-critical designs.

. Frequently Asked Questions (FAQs)

.1 What is the meaning of the MSL 2 rating?

MSL 2 (Moisture Sensitivity Level 2) indicates that the packaged LED can be exposed to factory floor ambient conditions (

.2 How do I interpret the two different Thermal Resistance (Rth JS) values?

The datasheet lists a "Real" Rth JS of 20-22 K/W and an "Electrical" Rth JS of 16 K/W max. The "real" value is typically measured using a physical temperature sensor and is considered more accurate for thermal modeling. The "electrical" method uses the temperature-sensitive forward voltage as a proxy for junction temperature. For conservative thermal design, using the higher "real" value (22 K/W) is recommended to ensure a sufficient safety margin.

.3 Can these LEDs be used in parallel without current balancing?

Direct parallel connection is generally not recommended without additional measures. Due to natural variations in forward voltage (even within a bin), LEDs in parallel will not share current equally. The LED with the slightly lower VF will draw more current, potentially leading to overheating and accelerated degradation. Using a separate current-limiting resistor for each LED or dedicated multi-channel constant-current drivers is the preferred method for driving multiple LEDs.

. Practical Design Case Study

Scenario:Designing an automotive CHMSL (Center High-Mount Stop Light) module using 10 pieces of the 2820-C02001M-AM LED.

Design Steps:

1. Electrical Design:Target operating current per LED: 200 mA for optimal efficiency and lifetime. Total current: 2.0A. Select a constant-current LED driver IC capable of delivering 2.0A, with an input voltage range covering the automotive battery system (9V-16V nominal, with load-dump transients). Choose LEDs from the same forward voltage bin (e.g., 3032) to minimize current imbalance if a single-channel driver is used with all LEDs in series.
2. Thermal Design:Estimate total power dissipation: 10 LEDs * (3.0V * 0.2A) = 6.0W. Using the conservative Rth JS of 22 K/W and assuming a target maximum junction temperature (Tj) of 110°C (below the 150°C max), calculate the required maximum solder point temperature: Ts_max = Tj_max - (Power_per_LED * Rth JS) = 110 - (0.6 * 22) = 96.8°C. The PCB must be designed with a thermal pad and sufficient copper area/thermal vias to keep Ts below this value in the expected ambient environment (e.g., inside a hot car trunk).
3. Optical/Mechanical Design:The 120-degree viewing angle may be sufficient for a CHMSL, but a reflector or lens may be added to meet specific photometric intensity requirements (e.g., SAE standards). The mechanical drawing provides the footprint for PCB layout and the dimensions for designing a holder or lens clip.
4. Component Selection:Order all 10 LEDs from the same luminous flux bin (e.g., F8) and the same chromaticity bin (e.g., 58M) to ensure uniform brightness and color across the light bar.

. Operating Principle Introduction

This LED is a phosphor-converted white LED. At its core is a semiconductor chip, typically made of indium gallium nitride (InGaN), that emits blue light when forward biased (electrical current flows through it). This blue light is partially absorbed by a layer of cerium-doped yttrium aluminum garnet (YAG:Ce) phosphor coating deposited on or near the chip. The phosphor absorbs some of the blue photons and re-emits light across a broad spectrum centered in the yellow region. The combination of the remaining unabsorbed blue light and the emitted yellow light is perceived by the human eye as white light. The exact shade of white (cool, neutral, warm) is determined by the ratio of blue to yellow light, which is controlled by the phosphor composition and thickness.

. Technology Trends

The trend in automotive LED lighting continues towards higher luminous efficacy (more lumens per watt), enabling brighter lights or lower power consumption and thermal load. There is also a strong drive for improved color rendering index (CRI) and color consistency, especially for interior ambient lighting where user experience is key. Miniaturization persists, with packages becoming smaller while maintaining or increasing light output. Furthermore, integration is a growing trend, with LED packages incorporating driver ICs, sensors, or communication interfaces for smart lighting systems. The emphasis on reliability and qualification for harsh environments (high temperature, humidity, vibration, chemical exposure) remains paramount in the automotive sector.
