20N03-TD from TDSEMIC, in a TO-252-2L. 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; the pin configuration drawing labels this lead G, with gate-source voltage rated at ±20 V maximum. |
| 2 | D | passive | Drain, connected to the exposed tab; rated for 30 V drain-source voltage and 20 A continuous drain current at Tc=25°C. |
| 3 | S | passive | Source; the pin configuration drawing labels this lead S, and the body diode is rated 24 A continuous source current. |
