2SA2127-AE

Single Bipolar Transistors Overview

The onsemi 2SA2127-AE is a PNP single medium-power bipolar junction transistor (BJT) housed in an MP package, equivalent to SC-51 or TO-92(1-WATT). It features a collector-to-emitter voltage of -50 V and a continuous collector current rating of -2 A. The device utilizes the MBIT process to achieve low saturation voltage and wide safe operating area (ASO). Key electrical characteristics include a DC current gain (hFE) ranging from 200 to 560 at -100 mA, a gain-bandwidth product of 420 MHz, and a collector-to-emitter saturation voltage of -0.4 V maximum at -1 A.
