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. |
