BC558 Transistor (Pack of 5)

BC558 PNP Transistor (Pack of 5)

The BC558 is a PNP bipolar junction transistor used to amplify or switch electronic signals and electrical power. It is described as a heavy-duty drop-in replacement for a 2N2222 or 2N3906.

A bipolar transistor has three terminals: the emitter, base and collector. A small current into the base controls a larger current flow from the collector to the emitter; the base current is typically about one-hundredth of the collector-emitter current. The large current flow is almost independent of the voltage across the transistor from collector to emitter, which makes large voltage amplification possible by taking the output voltage from a resistor in series with the collector.
