Working principle

The 1N5400-E3/73 operates using the PN junction. This type of rectifier diode is composed of a P-type and N-type semiconductor joined together at their junction. When a forward bias voltage is applied, the PN junction region is depleted and a current flows through the diode.

In forward bias operation, the diode acts like an AC switch, conducting current on the positive half of a cycle and blocking it on the negative half. The current is determined by the load resistance and the diode\'s forward voltage drop. In the reverse bias operation, the diode acts like an open switch and does not conduct current.
