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

DTD114ECT116 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 GND (EMITTER) power_in Ground/emitter of the built-in NPN transistor, connected to R2 and tied to circuit ground.
2 IN (BASE) input Input/base pin through built-in R1 = 10kΩ; VI(off) max 0.5V and VI(on) min 3.0V, input voltage rated -10 to 40V.
3 OUT (COLLECTOR) output Output/collector of the built-in NPN transistor, rated 50V supply (VCC) and 500mA maximum collector current.
