MPD18N20A from miracle, 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 at ±30 V maximum and a gate threshold of 2.0 V to 4.0 V. |
| 2 | D | passive | Drain, rated for VDS of 200 V and 18 A continuous at TC = 25°C (72 A pulsed); also connected to the exposed tab. |
| 3 | S | passive | Source; current return for the 18 A continuous drain current and the body diode (IS 18 A max). |
