CMD240A from Cmos(广东场效应半导体), 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 limited to ±20 V, threshold 1 V to 3 V at ID=250uA, with RDS(ON) specified at VGS=10 V and 4.5 V. |
| 2 | D | passive | Drain (also the mounting tab); rated for VDS of 40 V and continuous current of 80 A at TC=25℃. |
| 3 | S | passive | Source; carries up to 80 A continuous and is the body-diode anode side of the N-channel MOSFET. |
