CMD240 from Cmos, 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; drive with VGS up to ±20 V, with RDS(ON) below 4 mΩ at VGS=10 V and below 5 mΩ at VGS=4.5 V, and threshold of 1 to 3 V. |
| 2 | D | passive | Drain; rated for 40 V VDS, 80 A continuous at TC=25℃ (package limited) and 300 A pulsed. |
| 3 | S | passive | Source; carries up to 80 A continuous at TC=25℃ with diode forward voltage of 1 V max at 30 A. |
