DTC143XUAT106

ROHM Semicon · Digital Transistors · SOT-323

DTC143XUAT106 from ROHM Semicon, in a SOT-323. 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 power_in Ground, connected to the emitter and to R2 of the built-in bias network.
2 IN input Base input through built-in R1 (typ. 4.7 kΩ); input voltage range is −7 to +20 V.
3 OUT output Open-collector output of the NPN transistor; supply voltage max 50 V and output current max 100 mA.
