Do the cases of the four Mosfets of the H-bridge on the 24V23 have to be isolated from each other? Or is it acceptable to fit a single large heat-sink across all four mosfets, hence connecting them with a conductor? I have not been able to find any guidelines for fitting heat-sinks anywhere so far, any comments will be appreciated. Regards,
Hello.
The MOSFET housings are non-conductive, so you can use a single heat sink spanning all the MOSFETs. Just make sure you avoid shorting the leads of different components (or different exposed copper nodes on the PCB) together with the heat sink.
