Bestirpower · SiC Diodes · TO-247-2
BCA120S20D2 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 SiC Schottky diode, internally connected to the case/tab; VRRM 1200 V repetitive peak reverse voltage. |
| 2 | A | passive | Anode of the SiC Schottky diode; carries the forward current (IF 20 A at TC = 150℃, 58 A at TC = 25℃). |
