DTC123JU3HZGT106 from ROHM Semicon, in a SOT-323-3. 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 of the built-in NPN transistor, connected to the end of R2 (2.2kΩ/47kΩ bias network). |
| 2 | IN (BASE) | input | Input/base connected through R1 (2.2kΩ) with R2 (47kΩ) to GND; input voltage range -5 to 12 V, VI(on) min 1.1 V and VI(off) max 0.5 V. |
| 3 | OUT (COLLECTOR) | output | Output/collector of the built-in NPN transistor, rated for VCC 50 V and output current up to 100 mA. |
