Product Overview
The MMBTA92 is a PNP bipolar junction transistor designed for high-voltage, low-current switching and signal amplification. It features a 300V collector-emitter voltage rating, 100mA maximum collector current, and a minimum DC current gain of 25 at 30mA collector current. Its high breakdown voltage makes it suitable for communication, telephony, level-shifting, and other low-current control circuits operating at elevated voltages.
Packaged in a compact SOT-23 surface-mount package, the MMBTA92 is well suited to space-constrained PCB designs. It can be used in high-voltage PNP switching, discrete amplifier stages, interface circuits, and complementary transistor configurations.
