BC556 PNP Transistor - Black
The BC556 is a general-purpose PNP bipolar junction transistor suited to signal amplification and switching where a higher collector-emitter voltage rating is required. It is supplied in a through-hole TO-92 package and is rated for a collector-emitter voltage of -65 V and continuous collector current of -100 mA.
Selection guidance: Verify the manufacturer suffix, gain group, pinout, voltage, current, and thermal limits against the required circuit before installation.
