DTD123TCHZGT116

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

DTD123TCHZGT116 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; VEBO max 5 V and BVEBO min 5 V at IE = 50µA.
2 BASE input Base input through built-in series resistor R1 = 2.2kΩ (1.54 to 2.86kΩ), so no external input resistor is needed for inverter use.
3 COLLECTOR passive Collector of the built-in NPN transistor; VCEO 40 V, VCBO 50 V, IC max 500 mA.
