# HFFSH2065BDNF085

**HXY MOSFET** · SiC Diodes · TO-247

HFFSH2065BDNF085 from HXY MOSFET, in a TO-247. 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 | A1 | passive | Anode of the first Schottky diode (650 V repetitive peak reverse voltage); the other end of this diode joins the common cathode at pin 2 and the case. |
| 2 | K (CASE) | passive | Common cathode of both Schottky diodes, internally connected to the case/tab, per the page 1 internal diagram. |
| 3 | A2 | passive | Anode of the second Schottky diode (650 V repetitive peak reverse voltage); the other end of this diode joins the common cathode at pin 2 and the case. |
