. Application Suggestions

.1 Typical Application Scenarios

• Infrared Remote Control Units:Its high radiant intensity makes it suitable for remote controls requiring longer range or stronger signal penetration.
• Free-Air Transmission Systems:Used in short-range data links, proximity sensors, and object detection where an infrared beam is modulated.
• Smoke Detectors:Employed in obscuration-type smoke detectors, where smoke particles interrupt a beam of infrared light between an emitter and a receiver.
• General Infrared Systems:Any application requiring a dependable source of 940nm infrared light.

.2 Design Considerations

• Drive Circuit:Always use a series current-limiting resistor or a constant current driver to prevent exceeding the maximum forward current, especially given the low forward voltage. The IV curve should be used to calculate the appropriate resistor value for a given supply voltage.
• Thermal Management:Observe power dissipation limits. If operating near maximum current or in high ambient temperatures, consider the derating curve and ensure adequate ventilation or heat sinking if the LED is mounted on a board with other heat-generating components.
• Optical Alignment:The asymmetric viewing angle (95° x 45°) is critical. The LED and the corresponding receiver (phototransistor, etc.) must be aligned according to the intended axis of sensitivity to maximize collected signal.
• Reverse Voltage Protection:The maximum reverse voltage is only 5V. In circuits where reverse bias is possible (e.g., AC coupling or inductive loads), external protection such as a diode in parallel (cathode to anode) is strongly recommended.

. Technical Comparison and Differentiation

Compared to standard low-power infrared LEDs, the IR3494 series offers significantly higher radiant intensity (3.5 mW/sr typical vs. often less than 1 mW/sr for basic devices). This directly translates to longer operational range or the ability to use lower drive currents for the same range, improving efficiency. The 940nm wavelength is ideal as it is less visible to the human eye than 850nm LEDs (which have a faint red glow) while still being highly detectable by silicon-based photodetectors. The asymmetric beam pattern can be an advantage in applications requiring a focused beam in one plane and wider coverage in another.

. Frequently Asked Questions (Based on Technical Parameters)

Q: Can I drive this LED directly from a 5V microcontroller pin?

A: No. The forward voltage is only about 1.2-1.3V. Connecting it directly to 5V without a current-limiting resistor would cause a very high current to flow, destroying the LED instantly. A series resistor must always be used.

Q: What is the difference between the 'Typical' and 'Maximum' radiant intensity?

A: The typical value (3.5 mW/sr) is what most devices from a production batch will deliver. The maximum (5.5 mW/sr) is the upper limit of the specification; some devices may perform better, but designs should be based on the minimum (2.5 mW/sr) to ensure system functionality under all conditions.

Q: Why is the viewing angle different in X and Y directions?

A> This is a result of the internal chip structure and the shape of the plastic lens. It is an intentional design characteristic that shapes the emitted light pattern, which can be useful for targeting the infrared beam.

Q: Is a heat sink required?

A: For continuous operation at the maximum rated current of 100mA, the power dissipation is approximately 130mW (1.3V * 0.1A), which is below the 180mW rating at 25°C. However, if the ambient temperature is high or the LED is in a sealed enclosure, thermal derating per the performance curves must be applied, and a heat sink or reduced operating current may be necessary.

. Practical Design and Usage Case

Case: Designing a Long-Range IR Remote Control Transmitter

Objective: To achieve a reliable range of 15 meters in a typical living room environment.

Design Steps:

1. Drive Current Selection:Consult the 'Radiant Intensity vs. Forward Current' curve. To maximize range, operate near the upper limit. Selecting I_F= 80mA provides a radiant intensity of approximately 15 mW/sr (from the curve), a significant increase over the 20mA value.

2. Circuit Design:For a 3.3V supply, calculate the series resistor. Using the typical V_Fat 80mA (estimated from the IV curve as ~1.28V): R = (V_supply- V_F) / I_F= (3.3V - 1.28V) / 0.08A = 25.25Ω. Use a standard 24Ω or 27Ω resistor. Verify power in the resistor: P = I²R = (0.08)²*27 = 0.173W, so a 1/4W resistor is sufficient.

3. Thermal Check:LED power dissipation: P_d= V_F* I_F= 1.28V * 0.08A = 102mW. This is well within the 180mW limit at 25°C.

4. Optical Alignment:Mount the LED on the PCB edge of the remote. Orient the LED so its wider 95-degree plane (X) aligns horizontally to cover a broad area, while the narrower 45-degree plane (Y) is vertical to concentrate energy forward. This optimizes the chance of hitting the receiver even if the remote is slightly off-axis horizontally.

. Operating Principle

An Infrared Light Emitting Diode (IR LED) is a semiconductor p-n junction diode. When a forward voltage is applied, electrons from the n-region and holes from the p-region are injected across the junction. When these charge carriers recombine in the active region of the semiconductor material (typically based on gallium arsenide, GaAs), energy is released in the form of photons. The specific composition of the semiconductor layers determines the wavelength of the emitted light. For this device, the material is engineered to produce photons primarily at a wavelength of 940 nanometers, which is in the near-infrared spectrum, invisible to the human eye but easily detectable by silicon photodiodes and phototransistors.

. Technology Trends

The development of infrared LEDs continues to focus on several key areas: increasing wall-plug efficiency (optical power out / electrical power in) to enable lower power consumption or higher output from battery-operated devices; improving modulation speed for high-speed data communication applications like IrDA; and developing devices with even narrower spectral bandwidths for applications requiring precise wavelength matching, such as gas sensing. There is also a trend towards surface-mount device (SMD) packages for automated assembly, although through-hole packages like the T-1 3/4 remain popular for their robustness and ease of hand-soldering in prototyping and certain high-reliability applications. The 940nm wavelength remains a industry standard due to its optimal balance between silicon detector sensitivity and low visibility.
