BC556B PNP Through Hole Amplifier Transistor

BC556B is a PNP silicon epitaxial planar transistor rated for 65 V collector-emitter voltage and 100 mA collector current. It uses a TO-92 plastic package for leaded board assembly. The device is intended for switching and AF amplifier applications, giving engineers a straightforward PNP option for low-current discrete circuits. The BC556 type is offered in defined current-gain groups, including the B grouping represented by this part. When applying the device, set the bias point and operating margins with the circuit’s voltage, current, and thermal conditions in mind. BC556B combines a familiar through-hole package with a clearly defined PNP electrical range for supported switching and audio-frequency amplifier functions. Request a quote for BC556B.
