SFH 47278CS A01-CA1CB1
Overview
The SFH 47278CS is a high-power 950nm infrared emitter from the OSLON Black Series, specifically designed for automotive sensing and monitoring systems. It utilizes a double-stack emitter technology to achieve a high radiant intensity of 280mW/sr at 1A within a compact surface-mount package. This AEC-Q102 qualified LED is optimized for high-current pulse operation and features a wide viewing angle of 130 degrees by 155 degrees.
Why Choose This Part
This emitter offers exceptional thermal stability with an operating range up to 125 degrees Celsius and high ESD robustness of 8 kV. The 950nm wavelength is selected to minimize visible 'red glow' while remaining highly effective for standard CMOS IR sensors. Its double-stack architecture allows for increased optical output without increasing the component footprint.
Applications
Key Specifications
Getting Started
When designing with this high-power IR LED, ensure the PCB layout includes sufficient thermal vias to manage heat dissipation during 1.5A DC or high-current pulse operation. Use a constant-current LED driver capable of handling the 2.75V forward voltage drop and implement PWM control if variable intensity or synchronization with global shutter cameras is required.
