20N04-MS
MSKSEMI · MOSFETs · SOT-89
20N04-MS from MSKSEMI, in a SOT-89. 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 datasheet shows it as the left-hand lead of the SOT-89, with a Gate-Source voltage rating of ±20 V and a threshold of 1.0 to 2.5 V at ID=250μA. |
| 2 | D | passive | Drain; the middle lead, which is also connected to the package tab, with a Drain-Source voltage rating of 60 V and a breakdown of 40 V min at ID=250μA. |
| 3 | S | passive | Source; the right-hand lead of the SOT-89, with continuous drain current of 15 A at TA=25℃ flowing to it. |
