DTC143ZMT2L 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 (base) pin with built-in R1 = 4.7kΩ series resistor and R2 = 47kΩ to emitter; VI(off) max 0.5V, VI(on) min 1.3V, input voltage range -5 to 30V. |
| 2 | GND (EMITTER) | power_in | Ground (emitter) pin, common return for the input and output. |
| 3 | OUT (COLLECTOR) | output | Output (collector) pin, rated 50V supply voltage VCC and 100mA output current. |
