DTB123TCHZGT116

Overview

The DTB123TCHZGT116 is a PNP digital transistor with built-in bias resistors, manufactured by ROHM Semiconductor. It operates in an SOT-23-3 surface-mount package and meets AEC-Q101 automotive qualification standards. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of -40 V, a continuous collector current of -500 mA, and a power dissipation rating of 200 mW. The device features a typical input resistance (R1) of 2.2 kOhms and a minimum DC current gain (hFE) of 100 at -50 mA and -5 V. It supports a maximum operating frequency of 200 MHz and functions within a temperature range up to +150°C.
