DTC124EKA

Foshan Blue Rocket Elec · Digital Transistors · SOT-23

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.
