CMD609

Cmos · MOSFETs · TO-252-4L

CMD609 from Cmos, in a TO-252-4L. 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 S1 passive Source of the N-channel MOSFET (40V, 12A, RDS(ON)≤21mΩ at VGS=10V).
2 G1 input Gate of the N-channel MOSFET, VGS rated ±20V, threshold 1V to 2.5V.
3 S2 passive Source of the P-channel MOSFET (-40V, -12A, RDS(ON)≤32mΩ at VGS=-10V).
4 G2 input Gate of the P-channel MOSFET, VGS rated ±20V, threshold -1V to -2V.
5 D1/D2 passive Common drain of the N-channel and P-channel MOSFETs, connected to the exposed tab.
