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

DTC123JCAT116 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 terminal of the built-in NPN transistor, connected to the end of R2 (R2/R1 = 17 to 26).
2 IN (BASE) input Base input through built-in R1 (2.2kΩ typ), with VI(off) max 0.5V, VI(on) min 1.1V and input voltage rating -5 to 12V.
3 OUT (COLLECTOR) output Collector output of the built-in NPN transistor, rated up to VCC 50V and IO 100mA.
