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, and 3 are internally tied together as the source connection; typically bonded to the ground/return rail in low-side switching. Body diode anode. |+| 2 | S | passive | Source terminal (parallel connection with pins 1 and 3) to share current and reduce package resistance/inductance. Rated for ID = 50A continuous, IDM = 200A pulsed. |+| 3 | S | passive | Source terminal (parallel connection with pins 1 and 2). Body-diode anode; VSD ≤ 1.2V at ISD = 20A. |+| 4 | G | input | Gate terminal. Controls the channel via VGS; threshold VGS(th) = 1.1-2.4V (typ 1.6V). Absolute maximum VGS = ±20V. Total gate charge Qg ≈ 38.4nC at VGS = 10V. |+| 5 | D | passive | Drain terminal. Pins 5, 6, 7, 8 (and the exposed thermal pad) are internally the drain connection for the N-channel MOSFET. VDS rating = 30V. Body-diode cathode. |+| 6 | D | passive | Drain terminal (parallel with pins 5, 7, 8 and exposed pad). Used to carry drain current and conduct heat to the PCB. |+| 7 | D | passive | Drain terminal (parallel with pins 5, 6, 8 and exposed pad). Continuous drain current ID = 50A at TC = 25°C. |+| 8 | D | passive | Drain terminal (parallel with pins 5, 6, 7 and exposed thermal pad). All drain leads plus the pad should be soldered together to a copper plane to meet the 4.9°C/W junction-to-case thermal spec. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | GOFORD |+| Package | DFN-8L(5x6) |+| Category | Transistors/Thyristors |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `G50N03D5`++## CAD (KiCad official)++- Symbol: `G50N03D5`+- Footprint: `Package_DFN_QFN:DFN-S-8-1EP_6x5mm_P1.27mm`+- 3D model: DFN-8L(5x6) (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [GOFORD datasheet](https://www.gofordsemi.com/upload/cn/propdf/G50N03D5.pdf) (None pp, sha256 `731b3d4e30fe7344`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
