2SAR553PT100

Single Bipolar Transistors Overview

The 2SAR553PT100 is a PNP bipolar junction transistor manufactured by ROHM Semiconductor. It features a collector-emitter voltage (Vceo) of -50 V and a continuous collector current (Ic) of -2 A. The device utilizes the MPT3 package, equivalent to TO-243AA, with a power dissipation rating of 0.5 W. Key electrical characteristics include a DC current gain (hFE) ranging from 180 to 450 at -50 mA and -2 V, and a collector-emitter saturation voltage of 400 mV. The transition frequency (fT) is specified at 320 MHz, supporting operation up to a maximum junction temperature of +150°C.
