# OSD65R550

**OSEN** · MOSFETs · TO-252

OSD65R550 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 control input; gate-source voltage is rated at ±30 V maximum, with a threshold of 2.0 V to 4.0 V at VDS=VGS, ID=250 µA. |
| 2 | D | passive | Drain terminal; drain-source voltage is rated at 650 V maximum, with 7 A continuous and 25 A pulsed drain current. |
| 3 | S | passive | Source terminal; continuous body-diode forward current is 7 A maximum, with a forward voltage of 1.4 V maximum at IS=7 A. |

## CAD (KiCad official)

- Symbol: `OSD65R550`
- Footprint: `Package_TO_SOT_SMD:TO-252-2`
- 3D model: TO-252 (KiCad packages3D, STEP)
- 3D model files: `osd65r550-etched.step` / `osd65r550-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `osd65r550.step` / `osd65r550.glb` are the bare package body.
