Shikues · MOSFETs · TO-252
SK120N03B from Shikues, 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; drives the MOSFET with a Gate-to-Source voltage rating of ±20 V (RDS(ON) specified at VGS=10 V and 4.5 V). |
| 2 | D | passive | Drain (centre lead, also connected to the mounting tab); Drain-to-Source voltage 30 V, continuous drain current 120 A at TC=25℃. |
| 3 | S | passive | Source; body diode continuous source current up to 120 A, pulsed 480 A. |
