2STF2550

Single Bipolar Transistors Overview

The 2STF2550 is a PNP bipolar junction transistor manufactured by STMicroelectronics. It features a maximum collector-emitter voltage of 50 V and a continuous collector current of 5 A. The device dissipates up to 1.4 W of power and operates at junction temperatures reaching 150°C. Packaged in a surface-mount SOT-89-3 (TO-243AA) format, it exhibits a minimum DC current gain of 110 at 2 A and 2 V. The saturation voltage is specified at a maximum of 550 mV under 3 A collector current conditions.
