SFH 4715A
Overview
The SFH 4715A is a high-power infrared emitter from the OSLON Black Series, operating at a centroid wavelength of 850 nm. It is designed for high-efficiency radiant intensity, delivering up to 415mW/sr at 1A within a 90-degree viewing angle. The component features a low thermal resistance of 9 K/W and is housed in a robust 3-SMD package for reliable operation in demanding environments.
Why Choose This Part
This emitter offers exceptional thermal management with a maximum thermal resistance of only 9 K/W, allowing it to handle forward currents up to 1.5A safely. Its Class 3B corrosion robustness and 2 kV ESD rating make it suitable for harsh industrial or outdoor conditions. The 90-degree radiation pattern ensures broad, uniform coverage without the need for complex secondary optics in many applications.
Applications
Key Specifications
Getting Started
When designing with the SFH 4715A, ensure the PCB includes sufficient copper area for the thermal pad to maintain junction temperatures within the -40 to 125 degree Celsius range. Use a constant-current LED driver capable of delivering up to 1.5A with a forward voltage of approximately 1.65V. To evaluate the performance, engineers often use OSLON Black Series evaluation boards or custom star-PCB mounts to test radiant intensity and thermal dissipation.
