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. |
