STD2N80K5 from STMicroelectronics, in a TO-252-2(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 | Gate | input | Gate control input with ±30 V maximum gate-source voltage rating and 3-5 V gate threshold voltage. |
| 2 | Drain | output | Drain terminal with 800 V maximum drain-source breakdown voltage, 2 A continuous current at 25°C (1.3 A at 100°C), and 8 A pulse current capability. |
| 3 | Source | output | Source terminal providing return path for drain current and reference for gate voltage, with parasitic body diode rated for 2 A continuous source-drain current. |
