Diodes - Zener - Single

This article will discuss the SMZG3791B-E3/5B application field and working principle. The SMZG3791B-E3/5B is a single zener diode, intended for use as a regulator in electrical power supply systems.

Application Fields

The SMZG3791B-E3/5B is a single zener diode which is optimized for use in electrical power supply applications. It has a breakdown voltage of 37V and is capable of withstanding reverse voltages of up to 400V. This makes it ideal for use in high-voltage power supplies, such as the ones used in industrial machines and various other applications. Due to its low power consumption, the SMZG3791B-E3/5B can also be used in low-voltage and low-power applications, such as in signal processing and telecommunications equipment.

Working Principle

The basic operation of the SMZG3791B-E3/5B is similar to other zener diodes. In the forward direction, it acts as a regular diode, allowing electricity to flow through it in one direction only. In the reverse direction, the diode begins to breakdown and allows electricity to flow in both directions. This breakdown, or zener, voltage is what is used to regulate the electrical power supply output. The SMZG3791B-E3/5B can be used as a voltage regulator by connecting it to the power source and adjusting the source voltage until it is below the breakdown voltage of the diode. This will ensure that the output voltage does not exceed the specified voltage limit.

Conclusion

The SMZG3791B-E3/5B is a single zener diode designed for use in electrical power supply systems. It can be used to regulate high-voltage and low-power applications, such as those found in industrial machines and signal processing equipment. The diode works by allowing electricity to flow in one direction only until it reaches a certain breakdown voltage, at which point it begins to allow electricity to flow in both directions. By adjusting the source voltage, the output voltage of the power supply can be regulated.
