DTC143ECA

Changjing · Digital Transistors · SOT-23

DTC143ECA 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 pin of the built-in bias-resistor network (R1 nominal 4.7 kΩ, range 3.29 to 6.11 kΩ); the input voltage is rated from -10 V to +30 V, with VI(off) at most 0.5 V and VI(on) at least 3 V.
2 GND power_in Ground reference pin for the transistor; the datasheet gives no separate electrical limit for this pin.
3 OUT output Output pin of the NPN digital transistor, rated for an output current of 100 mA maximum, with VO(on) at most 0.3 V at IO/II = 10 mA / 0.5 mA and a supply voltage VCC up to 50 V.

CAD (KiCad official)

  • Symbol: DTC143ECA
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: dtc143eca-etched.step / dtc143eca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dtc143eca.step / dtc143eca.glb are the bare package body.
