**HXY MOSFET** · MOSFETs · DFN-8(5x6)

NTMFS4937N-HXY from HXY MOSFET, in a DFN-8(5x6). 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 | S | passive | Source terminal (Pin 1 marker); the datasheet rates continuous drain current at 120A at TC=25°C. |
| 2 | S | passive | Source terminal, tied to the same source node as the other S pins; the datasheet rates continuous drain current at 120A at TC=25°C. |
| 3 | S | passive | Source terminal, tied to the same source node as the other S pins; the datasheet rates continuous drain current at 120A at TC=25°C. |
| 4 | G | input | Gate terminal with a maximum gate-source voltage of ±20V and a gate threshold of 1V min to 2.5V max at 250µA. |
| 5 | D | passive | Drain terminal with a maximum drain-source voltage of 30V and a pulsed drain current of up to 360A. |
| 6 | D | passive | Drain terminal with a maximum drain-source voltage of 30V and a pulsed drain current of up to 360A. |
| 7 | D | passive | Drain terminal with a maximum drain-source voltage of 30V and a pulsed drain current of up to 360A. |
| 8 | D | passive | Drain terminal with a maximum drain-source voltage of 30V and a pulsed drain current of up to 360A. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
