ZXT12P12DXTA

Overview

The ZXT12P12DXTA is a dual PNP silicon switching transistor from Diodes Incorporated, housed in an MSOP8 package. It features a collector-emitter voltage (VCEO) of -12 V and a continuous collector current (IC) of -3 A per channel. The device exhibits extremely low saturation voltages, ranging from -65 mV at IC=-1 A to -190 mV at IC=-3 A with IB=-150 mA. Static forward current transfer ratios (hFE) reach up to 900 at IC=-12 A. Transition frequency is specified at 85 MHz. Operating junction temperature ranges from -55°C to +150°C.
