Polarity Reverse Protection (CB15055E)

Details
Written by: Newton C. Braga

 

For this circuit, the polarity of the power input does not matter, as the output terminals will always be correct. The diodes can be germanium for currents up to 50 mA and 1N4002 for currents up to 1 A. Remember that there is a small voltage drop in the diodes.
