DTC124EUA from TECH PUBLIC, in a SOT-323. 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 22kΩ series resistor R1 (with 22kΩ R2 to GND); input voltage rated -10 to +40 V, VI(OFF) min 0.5 V, VI(ON) max 3 V. |
| 2 | GND (EMITTER) | power_in | Emitter/ground terminal of the NPN digital transistor, also the return for the R2 22kΩ base-emitter resistor. |
| 3 | OUT (COLLECTOR) | output | Collector output of the digital transistor, rated 50 V supply (VCC), 30 mA output current (IO) and 100 mA max collector current. |
