Product Overview
The S8050 is an NPN bipolar junction transistor (BJT) designed for low-voltage switching and general-purpose signal amplification. It features a 25V collector-emitter voltage rating, 500mA maximum collector current, 300mW power dissipation, and 150MHz transition frequency. Its DC current gain makes it suitable for various low-power signal and driver circuits.
Packaged in a compact SOT-23 surface-mount package, the S8050 is suitable for LED switching, signal buffering, and small-load control applications. Its surface-mount design supports space-efficient PCB assembly, while appropriate base drive and thermal management help maintain reliable operation.
