Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | S | passive | Source terminal of the N-Channel MOSFET. Pins 1, 2, 3 are internally connected to the source and should be tied together on the PCB to carry the drain current (rated ID=80A @ TC=25°C). |+| 2 | S | passive | Source terminal of the N-Channel MOSFET. Internally bonded to pins 1 and 3; tie together on the PCB for full current handling. |+| 3 | S | passive | Source terminal of the N-Channel MOSFET. Internally bonded to pins 1 and 2; tie all source pins together on the PCB. |+| 4 | G | input | Gate terminal of the N-Channel MOSFET. Gate threshold VGS(TH)=1.0-2.5V (typ 1.7V); absolute maximum VGS=±20V. Drive with VGS≥4.5V for RDS(ON) ≤ 8 mΩ, or VGS=10V for RDS(ON) ≤ 6 mΩ. Total gate charge Qg≈38 nC. |+| 5 | D | passive | Drain terminal of the N-Channel MOSFET. Pins 5, 6, 7, 8 (and the exposed thermal pad) are internally connected to the drain; all must be tied together on the PCB and copper-poured for thermal dissipation (RθJA=30 °C/W). Rated V(BR)DSS ≥ 30V. |+| 6 | D | passive | Drain terminal of the N-Channel MOSFET. Internally bonded to pins 5, 7, 8 and the exposed thermal pad; tie together on the PCB. |+| 7 | D | passive | Drain terminal of the N-Channel MOSFET. Internally bonded to pins 5, 6, 8 and the exposed thermal pad; tie together on the PCB. |+| 8 | D | passive | Drain terminal of the N-Channel MOSFET. Internally bonded to pins 5, 6, 7 and the exposed thermal pad; tie together on the PCB for full-current and thermal path. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HXY MOSFET |+| Package | DFN-8(5x6) |+| Category | Transistors/Thyristors |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `NTMFS4C290N-HXY`++## CAD (KiCad official)++- Symbol: `NTMFS4C290N-HXY`+- Footprint: `Package_DFN_QFN:DFN-S-8-1EP_6x5mm_P1.27mm`+- 3D model: DFN-8(5x6) (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HXY MOSFET datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8602881198188208128) (None pp, sha256 `a418d5311e4e8ee8`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
