# OSD100N03T

**OSEN** · MOSFETs · TO-252

OSD100N03T 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 | G | input | Gate terminal of the N-channel MOSFET, rated for a gate-source voltage of ±20 V continuous with a threshold of 1.0 to 2.5 V. |
| 2 | D | passive | Drain terminal, rated for 30 V drain-source voltage and 100 A continuous drain current (400 A pulsed). |
| 3 | S | passive | Source terminal of the N-channel MOSFET, carrying up to 100 A continuous current. |

## CAD (KiCad official)

- Symbol: `OSD100N03T`
- Footprint: `Package_TO_SOT_SMD:TO-252-2`
- 3D model: TO-252 (KiCad packages3D, STEP)
- 3D model files: `osd100n03t-etched.step` / `osd100n03t-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `osd100n03t.step` / `osd100n03t.glb` are the bare package body.
