20SQ045 from LGE, in a R-6. 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 at the color-band end of the R-6 axial package; the part has 45 V repetitive peak reverse voltage (VRRM) and 20 A average rectified output current. |
| 2 | A | passive | Anode lead at the end of the R-6 axial package opposite the color band, carrying up to 20 A average forward current with 0.51 V maximum VFM at 20 A. |
