BC546 NPN Transistor – Datasheet

BC546 is an NPN epitaxial silicon transistor that is available in a TO-92 package. This transistor is very popular for its high voltage characteristics where the maximum voltage across collector-emitter (VCE) could be 65V and a maximum collector current of 100mA. It’s a low power loss, high-efficiency transistor ideal for automated placement with high surge current capability.
