Preventing Reverse Current in Distribution Boxes

Discover how reverse protection diodes, like Schottky and PN junction diodes, protect systems and components from possible harm by permitting current to flow in the right direction while obstructing it in the opposite. Reverse current is an event in which current travels in the opposite direction it should be moving through a system due to a high reverse bias voltage; from output to input. Fortunately, there are a handful of ways to protect your system from reverse current. Battery-operated equipment is prone to the consequences of batteries installed backward, accidental short circuits. Simplest is a diode -- as long as you can tolerate its reverse leakage current.
