Product Overview
The BC848B is an NPN bipolar junction transistor designed for general-purpose switching and small-signal amplification. It features a 30V collector-emitter voltage rating, 100mA maximum collector current, and a DC current gain range of 200–450 at 2mA collector current. Its defined B-grade gain range provides predictable performance for analog, interface, and low-current control circuits.
Packaged in a compact SOT-23 surface-mount package, the BC848B is suitable for signal amplification, buffering, discrete switching, and level-shifting applications. Its 100MHz minimum transition frequency and low collector capacitance also make it useful in compact low-power signal-processing designs.
