UF3M from DIYI Elec Tech, in a SMB. 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 | K | passive | Cathode, the end marked by the color band; UF3M is rated for 1000 V maximum recurrent peak reverse voltage and 3.0 A average rectified output current. |
| 2 | A | passive | Anode terminal; forward voltage is 1.7 V maximum at IF=3.0A for UF3M and the operating and storage temperature range is -55 to +175 °C. |
