DTC143XCA

Yangzhou Yangjie Elec Tech · Digital Transistors · SOT-23

DTC143XCA from Yangzhou Yangjie Elec Tech, 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 IN input Input terminal connected through built-in bias resistor R1 (typ 4.7 kΩ) to the base; input voltage rated -7 V to +20 V.
2 GND power_in Ground terminal connected to the emitter of the NPN transistor and to R2 (R2/R1 typ 2.1).
3 OUT output Output terminal at the NPN collector; rated 100 mA maximum output current and 50 V supply voltage.

CAD (KiCad official)

  • Symbol: DTC143XCA
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: dtc143xca-etched.step / dtc143xca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dtc143xca.step / dtc143xca.glb are the bare package body.
