DTC123EUAT106 from ROHM Semicon, in a SOT-323. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Emitter; connected to ground reference; also serves as the low side of the built-in R2 (2.2 kΩ) resistor network. |
| 2 | IN | input | Base input through built-in R1 = 2.2 kΩ series resistor; VI(off) max 0.5 V, VI(on) min 3.0 V (IO = 20 mA, VO = 0.3 V); max input voltage 12 V. |
| 3 | OUT | output | Collector output (open-collector); IC(MAX) 100 mA, VCEO 50 V; VO(on) typ 100 mV / max 300 mV at IO = 10 mA, II = 0.5 mA. |
