DTD123YCHZGT116

Overview

The DTD123YCHZGT116 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-23-3 surface-mount package. It integrates biasing resistors with a typical input resistance of 2.2 kOhms and an emitter-base resistance of 10 kOhms. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 500 mA. Key electrical parameters include a minimum DC current gain (hFE) of 100 at 50 mA and 5 V, a transition frequency of 200 MHz, and a power dissipation rating of 200 mW. It operates up to a maximum temperature of +150 C and holds AEC-Q101 automotive qualification.
