**HXY MOSFET** · MOSFETs · DFN5X6-8L

HAM7440N from HXY MOSFET, in a DFN5X6-8L. 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 marked on the package); continuous drain current is rated 40A at TC=25℃ and the source-drain diode forward current is up to 48A. |
| 2 | S | passive | Source terminal, tied in parallel with the other source pins; carries the continuous drain current rated 40A at TC=25℃ and 28A at TC=100℃. |
| 3 | S | passive | Source terminal, tied in parallel with the other source pins; pulsed drain current is rated 160A. |
| 4 | G | input | Gate terminal; gate-source voltage is rated ±20V, threshold is 1V min to 2.5V max at VDS=VGS, ID=250µA, and the part operates with gate voltages as low as 4.5V. |
| 5 | D | passive | Drain terminal, tied in parallel with the other drain pins; drain-source voltage is rated 40V with RDS(ON) below 14mΩ at VGS=10V. |
| 6 | D | passive | Drain terminal, tied in parallel with the other drain pins; continuous drain current is 40A at TC=25℃. |
| 7 | D | passive | Drain terminal, tied in parallel with the other drain pins; pulsed drain current is rated 160A. |
| 8 | D | passive | Drain terminal, tied in parallel with the other drain pins; drain-source breakdown voltage is 40V minimum at VGS=0V, ID=250µA. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
