I'm using 12- 100a mosfets connected in parallel as a ~300a switch for a battery spot welder. I posted a question a couple weeks ago about adding flyback diode protection and the consensus was that it wasn't needed for this application.
I just finish building the mosfet array last night. Going over my schematic and other DIY projects that are similar to this, just to double-check everything is correct. But all the other DIY mosfet switches like this are either using TVS diodes and or large schottky diodes and I just want to make sure I should be fine without adding them
The project that I followed in order to make mine has a large 300amp schottky diode between the drain and the source.
Just want to clarify if it's necessary... Thx
