Bestirpower · SiC Diodes · TO-247-2
BCA120S10D2 from Bestirpower, in a TO-247-2. 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 1200 V, 10 A SiC Schottky diode, internally connected to the case/mounting tab as shown in the schematic symbol. |
| 2 | A | passive | Anode of the 1200 V, 10 A SiC Schottky diode; forward current flows from this pin to the cathode. |
