BC857C

BC857C Description

The BC857C from Good Ark Semiconductor is a high-performance PNP bipolar junction transistor (BJT) designed for general-purpose amplification and switching applications. With a collector-emitter voltage (Vce) rating of 45V and a collector current (Ic) capability of 100mA, it offers robust performance in compact surface-mount packages. The transistor features a transition frequency (ft) of 150MHz, making it suitable for low-noise, high-frequency signal processing. Its low saturation voltage (650mV @ 5mA, 100mA) ensures efficient switching, while a high DC current gain (hFE ≥ 125 @ 2mA, 5V) guarantees stable amplification. Compliant with ROHS3 and REACH standards, the BC857C is packaged in Tape & Reel (TR) for automated assembly, with MSL 1 (Unlimited) moisture sensitivity for easy handling.
