2SA2222 PNP Power Transistor TO-220F Package

2SA2222: PNP Power Transistor for High-Current, Low VCE(sat) Switching

The 2SA2222 Transistor is a PNP bipolar power device designed for high-current, low-loss switching. With a collector-emitter voltage rating of 50 V and continuous collector current up to 10 A, the 2SA2222 is well-suited for relay, lamp, and motor drivers. Its low V_CE(sat) and fast switching enable efficient operation in compact power circuits. The device comes in a TO-220F (fully-isolated) package for improved thermal handling and simplified mounting.
