SFH 4715AS
Overview
The SFH 4715AS is a high-power 860nm infrared emitter from the OSLON Black Series designed for high-performance illumination. It utilizes a double-stack emitter chip to deliver a radiant intensity of 780mW/sr at 1A within a 90-degree viewing angle. This IR light source is optimized for high efficiency and low thermal resistance in demanding optical applications.
Why Choose This Part
The component features a low thermal resistance of only 9 K/W, allowing for efficient heat dissipation and sustained high-current operation up to 1.5A. Its double-stack technology significantly increases radiant flux compared to single-junction emitters, while the 860nm wavelength provides excellent camera sensitivity with reduced visible red glow.
Applications
Key Specifications
Getting Started
When designing with the SFH 4715AS, ensure the PCB footprint includes a large thermal pad connected to internal heat spreader layers to manage the 3.2V forward voltage at high currents. Use a constant-current LED driver capable of 1.5A and consider pulsing the current to achieve higher peak intensities while maintaining junction temperature. Proper optical shielding is recommended to prevent lens flare in integrated camera modules.
