DTA114TKAT146

ROHM Semicon · Digital Transistors · TO-236-3(SOT-23-3)

DTA114TKAT146 from ROHM Semicon, in a TO-236-3(SOT-23-3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 EMITTER passive Emitter of the built-in PNP transistor; VEBO is rated -5 V.
2 BASE input Base input through the built-in 10 kΩ (typ., 7 to 13 kΩ) bias resistor R1 in series with the transistor base.
3 COLLECTOR passive Collector of the built-in PNP transistor; VCEO is -50 V and IC is -100 mA max.
