Hi Mosaic,Considering this one as an option with a basic bolt on heat sink.

When using a MOSFET as a switch the drain/source parasitic diode only becomes a problem when the load retains a voltage (if the load were a battery for example) and the source goes to a low resistance when the source is turned off. In this situation the load will feed current back into the source through the parasitic diode. Otherwise you can forget about the parasitic diode as it will be reverse biased.Hi,
I want to control a < 40VDC line @ around 10A max with a PFET as a switch, high side.
Would the parasitic diode cause leakage when the PFET is switched off by a 0 Vgs?
Could that diode 'blow' shorted and disable the PFET as a high side switch?
