Advanced Power Switching and Polarity Protection for Effects
... When the battery leads are reversed, the MOSFET acts like an open circuit, as the nowpositive gate cannot enhance the drain-source channel, so there are only leakage currents flowing, and the inherent diode is reverse biased. So - the thing looks like an almost perfect polarity protection switch. Al ...
