# STD3N80K5

**STMicroelectronics** · MOSFETs · DPAK

STD3N80K5 from STMicroelectronics, in a DPAK. 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 | G | input | Gate control input rated for ±30 V gate-source voltage with threshold voltage 3-5 V. |
| 2 | D | passive | Drain terminal rated for 2.5 A continuous current at TC=25°C and 800 V drain-source breakdown voltage; TAB connects to drain for thermal dissipation. |
| 3 | S | power_in | Source terminal provides current return path; rated for ±30 V maximum gate-source voltage and 2.5 A reverse diode current. |

## CAD (KiCad official)

- Symbol: `STD3N80K5`
- Footprint: `Package_TO_SOT_SMD:TO-252-2`
- 3D model: DPAK (KiCad packages3D, STEP)
- 3D model files: `std3n80k5-etched.step` / `std3n80k5-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `std3n80k5.step` / `std3n80k5.glb` are the bare package body.
