Product Overview
The PZT2222A is an NPN bipolar junction transistor (BJT) designed for general-purpose switching and amplification. It features a 40V collector-emitter voltage rating, 1A maximum collector current, and 1W power dissipation. Its 300MHz transition frequency also makes it suitable for a range of signal amplification and switching applications.
Housed in a SOT-223-4 surface-mount package, the PZT2222A can be used in relay drivers, LED switching circuits, and discrete transistor output stages. Its compact package supports surface-mount PCB assembly, while its electrical characteristics make it a practical choice for medium-current switching applications.
