ZTX792ASTOA

Single Bipolar Transistors Overview

The ZTX792ASTOA is a PNP silicon planar medium-power high-gain transistor manufactured by Diodes Incorporated. It features a collector-emitter voltage (VCEO) of -70 V and a continuous collector current (IC) of -2 A, with a peak pulse current capability of -4 A. The device provides a static forward current transfer ratio (hFE) ranging from 300 to 800 at IC = -10 mA, and maintains a gain of 400 at IC = 3 A. Electrical characteristics include a transition frequency (fT) of 100 MHz and low saturation voltages, such as -0.5 V at IC = -1 A. Operating temperatures range from -55°C to +200°C.
