Product Overview
The MPSA94 is a PNP bipolar junction transistor designed for high-voltage, low-current switching and amplification. It features a 400V collector-emitter voltage rating, 300mA maximum collector current, and low collector-emitter saturation voltage. Its high breakdown voltage makes it suitable for level shifting, signal control, and discrete amplifier circuits operating at elevated voltages.
Packaged in a SOT-89 surface-mount package, the MPSA94 provides a compact solution for high-voltage PNP control stages. The SOT-89 version supports up to 500mW power dissipation and is suitable for telephone interface circuits, complementary high-voltage stages, and other low-current surface-mount applications.
