# HSS41F

**HXY MOSFET** · Hall Switches · TO-92S

HSS41F from HXY MOSFET, in a TO-92S. 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 | VSUP | power_in | Supply pin; the datasheet gives an operating supply range of 3.8 V to 60 V, an overvoltage capability of 80 V, and a reverse-supply voltage of -60 V as an absolute maximum, with an integrated reverse-supply protection diode. |
| 2 | GND | power_in | Ground pin, the reference for the supply and the open-collector output. |
| 3 | VOUT | output | Open-collector digital output that requires an external pull-up resistor; the datasheet gives an output current of up to 30 mA, Vsat of 0.4 V at IOUT = 20 mA, and an absolute maximum output voltage of 80 V. |
