Diodes - Zener - Single - PLZ7V5A-HG3/H Application Field and Working Principle

Zener diodes are through-hole or surface-mount devices widely used in very low-voltage power supplies. They are widely used in power supplies and rectification circuits as well as protection in low voltage systems. PLZ7V5A-HG3/H is a single Zener diode designed to protect and regulate the voltage in low voltage circuits. This diode has a breakdown voltage of 7V and a power dissipation range of 2W in standard commercial temperature.

Application

PLZ7V5A-HG3/H is typically used in low-voltage power supplies and rectification circuits. It is also used for protection in low voltage power circuits. It is well suited for use in applications that require a higher breakdown voltage than a Schottky rectifier and/or a lower forward voltage drop than an ultra fast rectifier.

Working Principle

A Zener diode is an electronic component that works with a reverse breakdown voltage and a low forward voltage drop. In a Zener diode, when the reverse bias voltage is above a certain voltage (known as Zener voltage or \'knee\' voltage), the diode breaks down and allows current to flow in the reverse direction. This phenomenon is called Zener breakdown. In a reverse biased diode, the electric field created by the negative charge on the n-type material is larger than the electric field created by the positive charge on the p-type material. This causes electrons to accumulate near the junction, facilitating current flow in the reverse direction.The PLZ7V5A-HG3/H Zener diode has a breakdown voltage of 7V, meaning that when the reverse bias voltage reaches 7V, the diode will break down and the current will flow in the reverse direction. Once the reverse bias voltage drops below 7V, the diode will turn off and the current will not flow. This process protects the circuit from excess voltage, thus allowing the circuit to function correctly.

Conclusion

The PLZ7V5A-HG3/H is a single Zener diode with a breakdown voltage of 7V and a power dissipation range of 2W in standard commercial temperature. This diode has been designed to protect and regulate the voltage in low voltage circuits. It is most commonly used in low-voltage power supplies and rectification circuits and can also be used for protection in low voltage power supplies. The Zener diode works by breaking down and allowing current to flow when the reverse bias voltage reaches a certain level, thus protecting the circuit from excess voltage.
