A reverse polarity protection diode blocks a backward supply at the cost of a permanent forward drop. How to work out the watts and choose the device.
A dual common anode Schottky diode puts two diodes on one shared anode. How pin configuration, forward drop and thermal limits decide the right part.
Updated: October 28, 2026 Automotive Schottky rectifiers trade lower forward drop for higher reverse leakage that rises fast with temperature — so the winning part is the one that meets reverse-voltage margin and hot leakage in your module, not the lowest VF on a cold data sheet.
