In addition, it can be used as a voltage limiter for protecting electrical components from high-voltage transients.

Working Principle: This device is a basic semiconductor device composed of a junction between a p-type semiconductor and an n-type semiconductor. In a forward-biased condition, electrons are injected from the n-side to the p-side, and some electrons from the valence band on the p-side move to the conduction band, resulting in a current flow from the p-side to the n-side. When reverse voltage is applied, holes are injected from the p-side to the n-side. Due to the built-in electric field, the carriers are repelled and the diode is in a reverse blocking condition. It is called a rectifier diode because it only allows current flow in one direction.

Summary: The 1N5397G-T is a single-phase silicon rectifier diode which has a wide array of applications in various electrical and electronic devices. It is mainly used in switching power supplies, DC-DC converters, high voltage rectifiers and photovoltaic systems. The basic principle of operation is the built-in electric field which allows current to flow only in one direction.
