Insulated MOSFET control terminal; VGS(TH) = 2-4 V (typ 3 V), VGS absolute max ±20 V. Drive to 10 V for full enhancement (RDS(ON) typ 14 mΩ). Total gate charge Qg ≈ 34 nC at VDS = 40 V, VGS = 10 V, ID = 20 A. |+| 2 | D | passive | Drain. Power terminal, also electrically connected to the TO-220 metal mounting tab for heat sinking. BVDSS ≥ 80 V, ID = 50 A continuous (35.4 A at TC = 100 °C), IDM = 85 A pulsed. Body diode: VSD ≤ 1.2 V at IS = 20 A, trr typ 21 ns. |+| 3 | S | passive | Source. Power return terminal and reference for VGS. Anode of the intrinsic body diode (drain is cathode). Handles up to ID = 50 A continuous. |+| TAB | D | passive | Metal mounting tab, electrically connected to the Drain. Provides thermal path to heatsink; RθJC = 1.36 °C/W, PD = 110 W at TC = 25 °C with derating 0.73 W/°C above 25 °C. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | GOFORD |+| Package | TO-220 |+| Category | Transistors/Thyristors |+| Pins | 4 |++## CAD (KiCad official)++- Symbol: `8850`+- Footprint: `Package_TO_SOT_THT:TO-220-3_Vertical`+- 3D model: TO-220 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [GOFORD datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8590919057346809856) (None pp, sha256 `7360c2eb9bf4e5bc`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
