**YFW** · Diodes - General Purpose · R-6

20A10 TB from YFW, 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, the lead at the banded end of the R-6 body; the part is rated for 1000 V maximum DC blocking voltage and 20 A average forward current. |
| 2 | A | passive | Anode, the lead at the end opposite the cathode band; forward voltage is 1.0 V maximum at 20 A. |
