AD-DTA143XM

Changjing · Digital Transistors · SOT-723

AD-DTA143XM from Changjing, in a SOT-723. 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 via built-in series resistor R1 (typ 4.7 kΩ) to the base; input voltage range -20 V to 7 V, VI(off) min -0.5 V, VI(on) max -2.5 V.
2 GND power_in Ground (emitter) reference of the PNP digital transistor, shown as GND(+) in the equivalent circuit; supply voltage Vcc is -50 V.
3 OUT output Open-collector output of the PNP transistor rated for output current IO of -100 mA, with VO(on) typ -0.1 V (max -0.3 V) at -10 mA.

CAD (KiCad official)

  • Symbol: AD-DTA143XM
  • Footprint: Package_TO_SOT_SMD:SOT-723
  • 3D model: SOT-723, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.5 mm nominal SOT-723 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: ad-dta143xm-etched.step / ad-dta143xm-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ad-dta143xm.step / ad-dta143xm.glb are the bare package body.
