Hello Forum,

I am trying to isolate a AC to DC power supply and a lead acid battery for a large robot. I am looking for two diodes to isolate each supply. System voltage will be at 12 volts. I expect a continuous 50 amps to be used at times and a peak of about a 100 amps for around 5-10 seconds max.

I attempted to search on the eBay and Amazon but I can't find any diodes that can take that much current.

I am looking for a recommendation on what diode to get and where to get it from.

Thank you for your help
