DTA143XCA

Changjing · Digital Transistors · SOT-23

DTA143XCA 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 to the built-in bias network (R1 = 4.7 kΩ typ., 3.29 to 6.11 kΩ); input voltage is rated −20 V to +7 V.
2 GND power_in Common ground reference for the device; the datasheet gives no separate electrical limit for this pin.
3 OUT output Output pin of the inverter stage, rated for output current up to −100 mA and supply voltage VCC down to −50 V, with on-state output voltage VO(on) of −0.1 to −0.3 V at IO/II = −10 mA/−0.5 mA.

CAD (KiCad official)

  • Symbol: DTA143XCA
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: dta143xca-etched.step / dta143xca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dta143xca.step / dta143xca.glb are the bare package body.
