Product Overview
The PZT2222A is an NPN bipolar junction transistor designed for general-purpose switching, driver, and amplification applications. It features a 40V collector-emitter voltage rating, 1A maximum collector current, and a minimum DC current gain of 100 at 150mA collector current. Its moderate current capability and 300MHz transition frequency make it suitable for compact driver, interface, and low-voltage switching circuits.
Packaged in a SOT-223 surface-mount package, the PZT2222A provides a larger thermal and current-handling platform than typical SOT-23 small-signal transistors. It is suitable for load switching, LED driving, signal amplification, and general-purpose transistor control stages.
