DTA123YKAT146 Description

Short technical summary and product information.

The DTA123YKAT146 is a PNP pre-biased bipolar transistor from ROHM Semiconductor. It integrates a 10 kΩ base resistor, enabling direct drive from microcontrollers or logic gates without additional external bias components. The device is rated for a maximum collector-emitter voltage of 50 V and a maximum collector current of 100 mA, with a power dissipation of 200 mW.

 

Electrical characteristics include a minimum DC current gain (hFE) of 33 at IC=10 mA and VCE=5 V, a maximum saturation voltage of 300 mV at IB=500 µA and IC=10 mA, and a minimum transition frequency of 250 MHz. The built-in resistor reduces external component count and simplifies switching and interface circuit design.

 

This device is supplied in a surface-mount SOT-23-3 (TO-236-3 / SC-59) package, with the supplier device package designation SMT3. The compact package is suitable for space-constrained PCB layouts and supports standard reflow soldering. The part is listed as RoHS3 compliant.
