Product Overview
The MMBT2222A is an NPN bipolar junction transistor designed for general-purpose switching, driver, and small-signal 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 relatively high current capability and 300MHz transition frequency make it suitable for compact driver, interface, and fast-switching circuits.
Packaged in a SOT-23 surface-mount package, the MMBT2222A is well suited to space-constrained PCB designs. It can be used in LED driving, low-voltage load switching, signal amplification, and general-purpose transistor control stages.
