DTC124EKA from Foshan Blue Rocket Elec, in a SOT-23. 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 | Base | input | Base terminal of the NPN digital transistor, which drives the built-in bias resistor R1 (typically 22 kΩ, range 15.4 to 28.6 kΩ). |
| 2 | Emitter | passive | Emitter terminal of the NPN digital transistor, the common return for the input and output circuit. |
| 3 | Collector | output | Collector terminal of the NPN digital transistor, rated for an output voltage VCC of 50 V and an output current IC of 100 mA. |
