18N50F
HXY MOSFET · MOSFETs · TO-220F
18N50F from HXY MOSFET, in a TO-220F. 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 terminal of the 18N50F; gate-to-source voltage is rated at ±30 V (VGSS) and the threshold is 2.0 V to 4.0 V at VDS=VGS, ID=250uA. |
| 2 | D | passive | Drain terminal; drain-to-source voltage is rated 500 V (VDSS) and continuous drain current is 18 A at Tc=25℃ (18 A at Tc=100℃ also listed). |
| 3 | S | passive | Source terminal; continuous source current is limited to 13 A (ISD) with pulsed source current of 52 A (ISM). |
