AD-DTC143TM

Changjing · Digital Transistors · SOT-723

AD-DTC143TM 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 Base input of the NPN digital transistor, driven through the built-in series resistor R1 (4.7 kΩ typ, 3.29-6.11 kΩ); VEBO rating is 5 V.
2 GND power_in Emitter of the NPN digital transistor, connected to ground in the inverter circuit.
3 OUT output Collector output of the NPN digital transistor; VCEO is 50 V and IC is up to 100 mA.

CAD (KiCad official)

  • Symbol: AD-DTC143TM
  • 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-dtc143tm-etched.step / ad-dtc143tm-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ad-dtc143tm.step / ad-dtc143tm.glb are the bare package body.
