DTA143ZM3T5G

onsemi · Digital Transistors · SOT-723

DTA143ZM3T5G from onsemi, 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 BASE input Base (input) of the PNP bias resistor transistor, connected through the 4.7 kΩ series resistor R1, with Input Forward Voltage max 30 Vdc and Input Reverse Voltage max 5 Vdc.
2 EMITTER power_in Emitter (ground) of the PNP digital transistor, the common reference for the input and output.
3 COLLECTOR output Collector (output) of the PNP digital transistor, rated for VCEO 50 Vdc and continuous IC 100 mAdc.

CAD (KiCad official)

  • Symbol: DTA143ZM3T5G
  • 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: dta143zm3t5g-etched.step / dta143zm3t5g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dta143zm3t5g.step / dta143zm3t5g.glb are the bare package body.
