Cmos · MOSFETs · TO-251
CMU9N20 from Cmos, in a TO-251. 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, with a maximum gate-source voltage of ±20 V and a gate threshold voltage of 2 V min to 4 V max at VGS=VDS, ID=250uA. |
| 2 | D | passive | Drain, rated for a 200 V drain-source voltage, 9 A continuous current at TC=25℃ and 32 A pulsed current. |
| 3 | S | passive | Source, carrying up to 9 A continuous drain current at TC=25℃ and a 9 A continuous body-diode source current. |
