Overview
The Fairchild MPSA93 is a silicon epitaxial planar PNP high-voltage transistor designed for switching and amplifier circuits. Operating at up to 200V collector-emitter voltage with 500mA continuous collector current, the MPSA93 delivers reliable performance in telephone signal switching, high-voltage driver applications, and industrial amplifier designs. The standard TO-92 package provides easy PCB insertion for both prototyping and production runs.
