DTA143ZCA

Changjing · Digital Transistors · SOT-23

DTA143ZCA 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 inverter, rated for an input voltage of -30 V to +5 V, with an input resistor R1 of 4.7 kΩ typical (3.29 kΩ to 6.11 kΩ).
2 GND power_in Ground pin; the datasheet states no separate electrical limit or function for this pin beyond its GND label.
3 OUT output Output pin, with an output current rating of -100 mA and a supply voltage VCC of -50 V maximum.

CAD (KiCad official)

  • Symbol: DTA143ZCA
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: dta143zca-etched.step / dta143zca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dta143zca.step / dta143zca.glb are the bare package body.
