Parallel connection of LEDs with different V_Fbins can cause uneven current distribution.
• Optical Design:The Lambertian-like radiation pattern allows easy integration into light guides or diffusers. The 120° viewing angle covers a wide area.
• Sulfur and Halogen Control:The environment must keep sulfur content below 100 ppm in mating materials. Bromine and chlorine contents in external materials should each be below 900 ppm, with a total below 1500 ppm, to prevent corrosion of the silver-plated leadframe.

. Technology Comparison

Compared to conventional red LEDs using GaAsP or GaP technologies, the AlGaInP-based RF-OMRB14TS-AK offers higher luminous efficacy (up to 40 lm/W at 20 mA) and better temperature stability. Its PLCC-2 package provides a smaller footprint than older through-hole parts and is compatible with automated SMT assembly. The 120° viewing angle is wider than many competing red LEDs (often 110° or less), giving more design flexibility for uniform lighting. AEC-Q101 qualification sets it apart from consumer-grade LEDs, making it suitable for safety-critical automotive applications.

. Frequently Asked Questions

Q: Can I drive this LED at 30 mA continuously?
A: Yes, the absolute maximum forward current is 30 mA DC, but you must ensure the junction temperature stays below 120 °C. At the maximum rated power of 72 mW (30 mA × 2.4 V), the temperature rise is 72 mW × 300 °C/W = 21.6 °C above the solder point. If the solder point is at 85 °C, the junction will be at 106.6 °C, which is safe. However, derating may be needed at higher ambient temperatures.

Q: What is the typical forward voltage at 20 mA?
A: The typical forward voltage is 2.0 V, but it can range from 1.8 V to 2.4 V depending on the bin. Design your circuit to accommodate this spread.

Q: Can I use this LED for exterior automotive lighting?
A: The datasheet specifies approval only for automotive interior. Exterior applications may require additional qualifications (e.g., AEC-Q102). However, the chip itself may be usable if properly protected from moisture and thermal stress.

Q: How should I clean the PCB after soldering?
A: Use isopropyl alcohol. Avoid ultrasonic cleaning as it can damage the LED. If other solvents are used, verify compatibility with the silicone encapsulation.

. Real-World Usage Case Studies

.1 Dashboard Ambient Lighting Module

A tier-1 automotive supplier designed a linear light guide for dashboard ambient strips using 12 RF-OMRB14TS-AK LEDs spaced at 10 mm intervals. Each LED was driven at 15 mA to achieve 400 mcd per segment. The wide 120° viewing angle ensured uniform brightness along the guide without hot spots. The module passed 1000-hour life tests at 85 °C/85% RH with less than 10% lumen depreciation.

.2 Center Console Backlighting

In a center console design, the LED was used as a direct backlight for capacitive touch buttons. A diffuser film was placed 3 mm above the LED. The resulting luminance exceeded 500 cd/m² at 20 mA. The high flux density of 800 mcd per LED allowed the use of fewer components compared to older-generation LEDs, reducing costs.

. Principle Explanation

The RF-OMRB14TS-AK uses AlGaInP (aluminum gallium indium phosphide) as the active layer material. When a forward bias is applied, electrons and holes recombine in the quantum well region, emitting photons with energy corresponding to the red part of the spectrum. The bandgap of AlGaInP can be tuned by adjusting the aluminum and indium composition; for red emission around 615 nm, the composition is optimized to achieve high internal quantum efficiency. The substrate (likely GaAs or GaP) is transparent to the emitted light, allowing light extraction from the bottom as well. The PLCC-2 package uses a transparent silicone encapsulant to protect the chip and serve as a lens. The cathode and anode are connected via silver-plated leadframes.

. Development Trends

The automotive LED market is moving toward higher efficiency and smaller packages. Future iterations of this product family may offer even higher luminous efficacy (e.g., >50 lm/W) through improved epitaxial design and better current spreading. Additionally, integration of ESD protection diodes in the package could simplify board-level design. The trend towards miniLED and microLED backlighting may eventually reach automotive interior, but PLCC-2 packages remain cost-effective for large-volume ambient lighting. Compliance with future automotive reliability standards (e.g., AEC-Q102 for photobiological safety) will be necessary.
