ZDT1053TC

Overview

The ZDT1053 is a dual NPN medium power transistor in an SM-8 package. It features a collector-emitter voltage (VCEO) of 75 V and a continuous collector current (IC) of 5 A. The device provides high DC current gain (hFE), with a minimum of 260 at IC = 10 mA and 300 at IC = 1 A. Collector-emitter saturation voltage (VCE(sat)) is less than 150 mV at IC = 1 A. Peak pulse current (ICM) reaches 20 A. Thermal resistance from junction to ambient is 45.5 °C/W when both dies are active. Operating temperature range spans from -55 °C to +150 °C.
