AOD4184A-MS from MSKSEMI, 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; controls the channel, with VGS rated ±20 V maximum and a threshold of 1.0 to 2.5 V at ID=250uA. |
| 2 | D | passive | Drain; the tab is also drain, with VDS rated 40 V and continuous current 50 A at TC=25℃. |
| 3 | S | passive | Source; the current return of the N-channel MOSFET, with a body diode of up to 50 A continuous source current. |
