Click to expand... You have to describe the "current" situation of the circuit you want to protect. For I<1A you can use somethnig like 1N4001/4 or 1N5819 (Schottky) .. For I>1A and <3A -- 1N5404 or 1N5822 .. etc ... https://www.edn.com/design/analog/4...larity-protection-circuit-has-no-voltage-drop :wink: IanP
