**STMicroelectronics** · MOSFETs · TO-220

STP6N80K5 from STMicroelectronics, in a TO-220. 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 | Gate | input | Gate control input with ±30 V maximum gate-source voltage rating, protected by internal Zener diode at 30 V breakdown voltage |
| 2 | Drain | passive | Drain terminal with 800 V maximum drain-source voltage rating (V(BR)DSS) and 4.5 A maximum continuous drain current at 25°C |
| 3 | Source | passive | Source terminal serving as return path for drain current and reference for gate-source voltage |

## CAD (KiCad official)

- Symbol: `STP6N80K5`
- Footprint: `Package_TO_SOT_THT:TO-220-3_Vertical`
- 3D model: TO-220 (KiCad packages3D, STEP)
- 3D model files: `stp6n80k5-etched.step` / `stp6n80k5-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `stp6n80k5.step` / `stp6n80k5.glb` are the bare package body.
