DTC143XCAHZGT116

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

DTC143XCAHZGT116 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 Emitter of the built-in NPN transistor, connected to ground, with R2 (10kΩ) connected between it and the base side of the input.
2 IN (BASE) input Input (base) through built-in R1 = 4.7kΩ, with VI(off) max 0.3V, VI(on) min 2.5V and input voltage rating of -7 to 20V.
3 OUT (COLLECTOR) output Output (collector) of the built-in transistor, rated for VCC 50V and output current IO up to 100mA.
