DTC143TKA

Foshan Blue Rocket Elec · Digital Transistors · SOT-23

DTC143TKA 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 has built-in bias resistors (R1 = 4.7 kΩ typ., 3.29 to 6.11 kΩ) for simplified switching and inverter circuits.
2 Emitter passive Emitter terminal of the NPN digital transistor, intended for switching, inverter, interface and driver circuit applications.
3 Collector passive Collector terminal of the NPN digital transistor; absolute maximum collector current is 100 mA and collector-emitter voltage is 50 V.
