DSS5140V-7

Single Bipolar Transistors Overview

The DSS5140V-7 is a low VCE(SAT) PNP surface mount transistor manufactured by Diodes Incorporated. It utilizes epitaxial planar die construction and is housed in an SOT-563 case. The device supports a maximum collector current of -1 A and withstands collector-emitter voltages up to -40 V. Key electrical parameters include a DC current gain (hFE) ranging from 160 to 800, a collector-emitter saturation voltage of -310 mV at -1 A, and a transition frequency (fT) of 150 MHz. Power dissipation reaches 600 mW with a thermal resistance of 208 °C/W.
