DTC123EMT2L from ROHM Semicon, in a SOT-723. 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 | IN (BASE) | input | Input terminal connected to the transistor base through built-in bias resistor R1 (2.2kΩ typ.), with an input voltage rating of -10 to 12 V. |
| 2 | GND (EMITTER) | power_in | Ground terminal connected to the transistor emitter, which also connects to the base through built-in resistor R2 (2.2kΩ typ.). |
| 3 | OUT (COLLECTOR) | output | Output terminal connected to the transistor collector, rated for up to 100 mA output current and 50 V supply voltage. |
