DTC114WUA

Changjing · Digital Transistors · SOT-323

DTC114WUA from Changjing, 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 input Input pin; the datasheet limits the input voltage to -10 to +30 V, with VI(off) at most 0.8 V and VI(on) at least 3 V.
2 GND power_in Ground reference pin for the built-in bias-resistor inverter circuit.
3 OUT output Output pin; the datasheet limits the output current to 100 mA maximum, with VO(on) at most 0.3 V at IO/II = 10 mA/0.5 mA.

CAD (KiCad official)

  • Symbol: DTC114WUA
  • Footprint: Package_TO_SOT_SMD:SOT-323_SC-70
  • 3D model: SOT-323 (KiCad packages3D, STEP)
  • 3D model files: dtc114wua-etched.step / dtc114wua-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dtc114wua.step / dtc114wua.glb are the bare package body.
