DTC123JU3T106

ROHM Semicon · Digital Transistors · SOT-323

DTC123JU3T106 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 (EMITTER) power_in Ground/emitter terminal of the built-in NPN transistor, connected to the common return of the inverter circuit.
2 IN (BASE) input Input terminal connected to the base through built-in bias resistor R1 of 2.2kΩ (R2 47kΩ to emitter), with input voltage rated -5 to 12 V.
3 OUT (COLLECTOR) output Open-collector output of the built-in NPN transistor, rated for 50 V supply voltage and 100 mA output current.
