# SF56-B

**GOODWORK** · Fast Recovery / High Efficiency Diodes · DO-27

SF56-B from GOODWORK, in a DO-27. 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 axial lead on the color-band end of the body; SF56 has 400 V maximum recurrent peak reverse and DC blocking voltage. |
| 2 | A | passive | Anode, the axial lead opposite the color band; SF56 passes 5.0 A maximum average forward current with 1.30 V maximum forward voltage at 5.0 A. |
