# MD33N25

**Minos** · MOSFETs · TO-247

MD33N25 from Minos, in a TO-247. 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 of the N-channel MOSFET, with a maximum gate-to-source voltage of ±30 V and a threshold of 2.0 to 4.0 V. |
| 2 | D | passive | Drain terminal of the N-channel MOSFET, rated for a drain-to-source voltage of 250 V and a continuous drain current of 33 A. |
| 3 | S | passive | Source terminal of the N-channel MOSFET, with the body diode rated for a continuous source current of 33 A. |

## CAD (KiCad official)

- Symbol: `MD33N25`
- Footprint: `Package_TO_SOT_THT:TO-247-3_Vertical`
- 3D model: TO-247 (KiCad packages3D, STEP)
- 3D model files: `md33n25-etched.step` / `md33n25-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `md33n25.step` / `md33n25.glb` are the bare package body.
