DTC144EMT2L 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 | Base input through built-in R1 = 47kΩ; VI(off) max 0.5V, VI(on) min 3.0V, input voltage range -10 to 40V. |
| 2 | GND (EMITTER) | power_in | Ground/emitter terminal, connected to the input through built-in R2 = 47kΩ. |
| 3 | OUT (COLLECTOR) | output | Collector output, with supply voltage VCC 50V max and output current IO 30mA (collector current IC(MAX) 100mA). |
