2SC3074-Y(Q)

Single Bipolar Transistors Overview

The Toshiba 2SC3074-Y(Q) is a silicon NPN epitaxial planar transistor utilizing the PCT process, designed for high current switching applications. It features a low collector saturation voltage of 0.4 V maximum at 3 A and a typical storage time of 1.0 μs. The device supports a continuous collector current of 5 A and a collector-emitter voltage of 50 V. The 'Y' suffix indicates a DC current gain (hFE) classification of 120 to 240 at IC = 1 A. It is packaged in a TO-220AB style case.
