BCH65S20D3 from Bestirpower, in a TO-220-2. 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 of the 650 V, 20 A SiC Schottky diode, internally connected to the case (mounting tab) per the page 1 symbol. |
| 2 | A | passive | Anode of the 650 V, 20 A SiC Schottky diode, with the diode drawn from pin 2 toward the cathode/case node on the page 1 symbol. |
