VSMY2940GX01
Overview
The VSMY2940GX01 is a high-performance 940nm infrared emitting diode based on Vishay Surface Emitter technology. This AEC-Q101 qualified component features a narrow 20-degree half-intensity angle and high radiant intensity of 75mW/sr at 100mA, making it ideal for long-range or high-precision sensing applications. Its gullwing SMD package is designed for high-reliability environments and is mechanically compatible with the VEMD2000X01 series detectors.
Why Choose This Part
The surface emitter technology provides very high radiant power and intensity, allowing for increased range or reduced power consumption compared to standard IR LEDs. AEC-Q101 qualification ensures long-term reliability in harsh automotive temperatures from -40 to 85 degrees Celsius, while the narrow 20-degree beam angle minimizes optical crosstalk.
Applications
Key Specifications
Getting Started
When designing for high pulse current operation, ensure the PCB thermal management can handle the peak dissipation of the 100mA continuous forward current. Pair this emitter with the VEMD2000X01 series photodiode for matched spectral sensitivity at 940nm. Use a standard constant-current LED driver with a 1.4V forward voltage drop to maintain stable radiant intensity across temperature fluctuations.
