Vishay VSMB3940X01GS08 Infrared Emitting Diode

The VSMB3940X01-GS08 is a 940nm infrared emitting diode built with Gallium Aluminum Arsenide (GaAlAs) double heterojunction technology, in a surface-mount PLCC-2 package. It offers high radiant power and high speed, making it ideal for IrDA data transmission, optical switches, and control circuits. With a half-intensity angle of ±60°, low forward voltage, and a maximum modulation bandwidth of 24 MHz, it guarantees reliable operation in miniature light barriers, photointerrupters, and shaft encoders. AEC-Q101 qualified, RoHS compliant, and suitable for high pulse currents.
