DTC124EETL from ROHM Semicon, in a SOT-416. 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; R2 (22kΩ) is connected between this pin and the base. |
| 2 | IN (BASE) | input | Input / base of the NPN digital transistor through built-in R1 = 22kΩ; VI(off) max 0.5V, VI(on) min 3.0V, input voltage range -10 to 40V. |
| 3 | OUT (COLLECTOR) | output | Output / collector of the NPN transistor; supply voltage VCC max 50V, output current IO max 30mA (IC(MAX) 100mA). |
