K220 from DOWO, in a SOD-123FL. 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, marked by the cathode line on the package; the K220 blocks up to VRRM = 200 V repetitive peak reverse voltage. |
| 2 | A | passive | Anode; the K220 carries up to 2.0 A average rectified output current (IO) in forward conduction. |
