Working Principle

The basic principle of 1N4738A-T50R is based on the behaviour of an atom. When electric current passes through a diode, it drags electrons from the N-type side, where they move to the P-type side. During this moving process, electric field is generated across the PN junction, and which creates a barrier between the two layers. This barrier, called Zener barrier, is a very stable characteristic, and it can limit the electric current and voltage applied to it.

A Zener barrier works in a reverse-bias condition, which means that the PN junction is connected in a reverse direction to the current flow. The reverse voltage applied to the junction is called the Zener voltage. When the reverse voltage exceeds the Zener voltage, electrons are pushed across the junction, which results in an electric current flowing in the diode. This electric current is called Zener current and it is limited by the Zener voltage.

When the applied voltage reaches a certain level, the Zener diode will start to conduct, and thus it can limit the output voltage. This function can be used in a variety of applications, such as overvoltage protection, voltage regulators, and voltage multipliers.

The 1N4738A-T50R is a very reliable and cheap Zener diode that can be used in a wide range of applications. It has a wide range of voltages available and it can be used for low voltage applications.
