DTC114TKAT146

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

DTC114TKAT146 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 NPN transistor; emitter-base voltage is limited to 5 V (VEBO).
2 BASE input Base input through the built-in 10 kΩ resistor R1 (7 to 13 kΩ), so no external input resistor is needed.
3 COLLECTOR passive Collector of the built-in NPN transistor; VCEO 50 V and IC 100 mA maximum.
