2SD1782KT146R

Single Bipolar Transistors Overview

The 2SD1782KT146R is an NPN bipolar power transistor manufactured by ROHM Semiconductor, designed for driver applications. It features a collector-emitter voltage (VCEO) of 80V and a continuous collector current (IC) of 500mA. The device operates with a maximum power dissipation of 200mW at 25°C ambient temperature. Key electrical characteristics include a typical collector-emitter saturation voltage (VCE(sat)) of 0.2V at IC=500mA and IB=50mA, and a transition frequency (fT) of 120MHz. The unit utilizes the SOT-346 (SC-59/SMT3) surface-mount package.
