Series Diode Reverse Polarity Protection. The series diode protection has a disadvantage, especially at low input voltages, due to the voltage drop across the diode. Depending on the choice of diode, a forward voltage drop of 0.2V to 0.7 V can be expected, with an associated power loss = VF × IIN, which reduces both the conversion efficiency ...Reverse Polarity Protection with a Schottky Diode. An easy way to mitigate both of the above disadvantages is to use a Schottky diode instead of a normal diode. This approach reduces voltage loss and power dissipation. I'm not sure how low Schottky diodes can go, but in some cases the forward voltage can be below 300 mV.Reverse polarity is one of the easiest issues in electrical wiring to correct.
