2SD1207S-AE

Single Bipolar Transistors Overview

The 2SD1207S-AE is an NPN single bipolar transistor manufactured by onsemi, designed for large-current switching applications. It features a collector-to-emitter voltage rating of 50 V and a continuous collector current capacity of 2 A, with a peak pulse current of 4 A. The device operates within a junction temperature range of -55 °C to +150 °C and dissipates up to 1 W of power. Key electrical characteristics include a DC current gain (hFE) ranging from 140 to 400 at 100 mA, a low collector-to-emitter saturation voltage of 0.15 V to 0.4 V at 1 A, and a gain-bandwidth product of 150 MHz.
