SMZG3795B-E3/52 Application Field and Working Principle

Diodes - Zener - Single is a type of Zener diode, which is a semiconductor device consisting of two terminals that are connected to a single p-n junction. The SMZG3795B-E3/52 is a specially designed device that provides high-voltage and low-current protection when placed correctly in an electrical circuit. With its ability to dissipate large currents in a very short period of time, this device is also suitable for short circuit protection.

The Zener diode is named after Dr. Clarence Zener, who first discovered the property of Zener breakdown in the early 1930s. Zener breakdown is a phenomenon where a large electric current passes suddenly through a reverse bias p-n junction diode, resulting in an abrupt avalanche breakdown. This uncontrolled current is called a Zener or avalanche current. The discovery of Zener breakdown is an important development in semiconductor physics, as it enables the production of diodes with precise breakdown voltages.

The SMZG3795B-E3/52 is a Zener diode with a breakdown voltage of 39V and a Zener current of 5mA. It is used in many applications where ultra-high Zener voltage and low Zener current are required. It is known for its long life and reliability. The device is available in multiple package types which makes it easy to integrate into different circuit boards.

The working principle of a Zener diode is based on the principle of electrostatic induction. When a reverse bias voltage is applied to the diode, it creates an electric field which causes electrons to be attracted to the p-n junction. When the reverse bias voltage reaches the Zener voltage, the electric field becomes so intense that electrons tunnel across the p-n junction and create a current. This current then passes through the diode, while being dissipated as heat.

The SMZG3795B-E3/52 has various uses in different applications. It is used in voltage regulation and as a reference voltage source in Automotive Control Systems, such as Vehicle Electronic Control Units (ECU). It is also used in high voltage power supplies, voltage multipliers and surge protectors, as well as other power supply and protection related applications. The device is also suitable for automotive, military and aerospace applications, where high stability and high reliability is required.

In conclusion, the SMZG3795B-E3/52 is a reliable and highly efficient Zener diode designed for medium current and ultra-high Zener voltage requirements. Being able to dissipate large currents in a very short period of time, the device is suitable for high-voltage and low-current protection and is able to offer excellent protection against over and undervoltage in many circuit applications.
