# OSD50N10G

**OSEN** · MOSFETs · TO-252

OSD50N10G from OSEN, in a TO-252. 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 terminal; gate-source voltage limited to ±20 V with threshold of 1.2 V min to 2.5 V max at ID=250µA. |
| 2 | Drain | passive | Drain terminal (also the tab); drain-source voltage rated 100 V with 50 A continuous drain current. |
| 3 | Source | passive | Source terminal; carries up to 50 A continuous drain current and 50 A continuous body-diode forward current. |

## CAD (KiCad official)

- Symbol: `OSD50N10G`
- Footprint: `Package_TO_SOT_SMD:TO-252-2`
- 3D model: TO-252 (KiCad packages3D, STEP)
- 3D model files: `osd50n10g-etched.step` / `osd50n10g-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `osd50n10g.step` / `osd50n10g.glb` are the bare package body.
