# HMBRF1045CT

**HXY MOSFET** · Schottky Barrier Diodes (SBD) · TO-220F

HMBRF1045CT from HXY MOSFET, in a TO-220F. 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 leg, with the cathode common at pin 2; rated 5A per leg for forward voltage and 10A total average forward current. |
| 2 | K | passive | Common cathode of both Schottky diode legs, joined at the center pin; rated 10A maximum average forward current and 150A peak forward surge current. |
| 3 | A2 | passive | Anode of the second Schottky diode leg, with the cathode common at pin 2; rated 5A per leg for forward voltage and 10A total average forward current. |
