# HSP0139

**HUASHUO** · MOSFETs · TO-220

HSP0139 from HUASHUO, 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 | G | input | Gate; gate-source voltage is limited to ±20 V absolute maximum, with a gate threshold of -1.2 V min to -2.5 V max at ID=-250uA. |
| 2 | D | passive | Drain; drain-source voltage is rated -100 V with continuous drain current of -35 A at TC=25℃ and pulsed drain current of -100 A. |
| 3 | S | passive | Source; continuous source (body diode) current is rated -35 A. |

## CAD (KiCad official)

- Symbol: `HSP0139`
- Footprint: `Package_TO_SOT_THT:TO-220-3_Vertical`
- 3D model: TO-220 (KiCad packages3D, STEP)
- 3D model files: `hsp0139-etched.step` / `hsp0139-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `hsp0139.step` / `hsp0139.glb` are the bare package body.
