# UF1010

**SUNMATE Elec** · Fast Recovery / High Efficiency Diodes · DO-41

UF1010 from SUNMATE Elec, in a DO-41. 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 lead, identified by the cathode band on the molded body ("Polarity: Cathode Band"); the rectifier conducts forward from anode to cathode, with a 1.0 A average rectified output current and 50 to 1000 V repetitive reverse voltage rating. |
| 2 | A | passive | Anode lead, the non-banded end opposite the cathode band; the datasheet gives no separate anode marking, so this lead is identified by elimination from the cathode band. |
