DTC143ECA-TP

MCC Micro Commercial Components · Digital Transistors · SOT-23

DTC143ECA-TP from MCC Micro Commercial Components, 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 digital transistor, with input voltage rated from -10 V to +30 V per the maximum ratings.
2 GND power_in Ground reference pin, marked GND(+) on the internal structure diagram.
3 OUT output Output pin of the transistor, with output voltage VO(on) at most 0.3 V when on and collector current Ic rated at 100 mA.

CAD (KiCad official)

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