ZXTD09N50DE6TA

Overview

The ZXTD09N50DE6TA is a dual NPN low saturation switching transistor manufactured by Diodes Incorporated. It features a collector-emitter breakdown voltage (BVCEO) of 50V and supports a continuous collector current (IC) of 1A. The device utilizes an SOT-26 surface-mount package with a maximum power dissipation of 1.1W at +25°C. Electrical characteristics include a DC current gain (hFE) minimum of 200 at IC=500mA, VCE=2V, and a collector-emitter saturation voltage (VCE(sat)) of 270mV maximum at IC=1A, IB=50mA. The transition frequency (fT) is 215MHz at VCE=10V, IC=50mA. Operating temperature ranges from -55°C to +150°C.
