AOD458 from Alpha Omega Semicon, 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; gate-source voltage is limited to ±30 V maximum, with a typical threshold of 3.8 V (3 V to 4.5 V) at ID=250µA. |
| 2 | D | passive | Drain, also the exposed tab; drain-source voltage is 250 V maximum with 14 A continuous current at TC=25°C. |
| 3 | S | passive | Source; carries the 14 A maximum continuous body-diode and channel current at TC=25°C. |
