HL · MOSFETs · TO-252
20N03 from HL, 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 of the MOSFET; the datasheet rates gate-source voltage VGS at ±20 V, and VGS(th) is 1 to 2.5 V at VGS=VDS, ID=250µA. |
| 2 | D | passive | Drain of the MOSFET; the datasheet rates drain-source voltage VDS at 30 V and continuous drain current ID at 20 A (TC=25℃). |
| 3 | S | passive | Source of the MOSFET; the datasheet gives continuous source current IS as 9 A maximum. |
