DTA114ECA

Changjing · Digital Transistors · SOT-23

DTA114ECA from Changjing, 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 of the built-in bias-resistor inverter; the datasheet's maximum input voltage (VIN) is -40 V to +10 V.
2 GND power_in Ground reference terminal of the device; the datasheet gives no separate electrical limit for this pin.
3 OUT output Output terminal of the transistor; the maximum ratings give an output current (IO) of -50 mA and a peak collector current (ICM) of -100 mA.

CAD (KiCad official)

  • Symbol: DTA114ECA
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: dta114eca-etched.step / dta114eca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dta114eca.step / dta114eca.glb are the bare package body.
