UFD320

DIYI Elec Tech · Fast Recovery / High Efficiency Diodes · TO-252

UFD320 from DIYI Elec Tech, in a TO-252. 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 N/A unconnected Not connected; the package diagram marks pin 1 as N/A.
2 K passive Cathode of the 200 V, 3 A ultrafast rectifier; the diagram shows it as the center pin 2, which is also the tab.
3 A passive Anode of the 200 V, 3 A ultrafast rectifier; the diode symbol in the package diagram points from pin 3 toward pin 2.

CAD (KiCad official)

  • Symbol: UFD320
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252 (KiCad packages3D, STEP)
  • 3D model files: ufd320-etched.step / ufd320-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ufd320.step / ufd320.glb are the bare package body.
