Diode should be overrated compared to the fuse, so it won't blow before the fuse. In this case, a resettable fuse clearly is a good choice :) Since there's no voltage drop, why using Schottky diodes (since they're also less resistant) ? What not just "usual" diodes like 1N4001 (or 1N4007) ? TIA Seb -- You received this message because you are subscribed to the Google Groups "jallib" group.
