Diodes are semiconductor components used for current rectification, voltage regulation, and signal switching between circuits. Within the diode category, Zener diodes are the most commonly used for special purposes such as stabilizing voltage, in the field of power electronics. A Zener diode is a particular type of semiconductor diode that has a breakdown voltage low enough for a single diode to regulate voltage in a circuit. The BZV55C2V4 is a single Zener diode whose main purpose is to provide a regulated voltage to a circuit from a higher DC supply.

BZV55C2V4 Application Field

The BZV55C2V4 is commonly applied in all kind of memory circuits and radio frequency circuits, to keep the circulating current of the power cord within a certain range. It is widely used in television receivers and computers as clipper, clamp and decoupling as well as in wide range of other applications. It can also be used in temperature systems and automatic control equipment and it has been found to be ideal for circuit protection due to its superior reverse voltage characteristics. This Zener diode is also an ideal choice for voltage regulation of automotive and telecom systems.

BZV55C2V4 Working Principle

The working principle of the BZV55C2V4 is based on the PN Junction. A PN Junction is a device made of semiconductor material which does not, in itself, carry a current. Instead, when an electric field is applied to it, current can flow through it. The PN Junction operates as a diode, allowing current to flow in only one direction. When a current is applied to the PN Junction from the anode side the minority carrier’s slow movement to the P-type material produces a built-in field and reduces the PN junction barrier. The BZV55C2V4 is constructed using a PN Junction which allows it to handle higher reverse voltages.

The Zener diode is connected in reverse bias in the circuit so that it experiences a reverse electric potential relative to its anode. This causes electrons to move from the anode side to the cathode side to create an electric field across the PN Junction. When the applied reverse voltage reaches the zener voltage, the electric field across the junction becomes strong enough to cause a breakdown. As an electric current is applied, the barrier between the regions breaks down and allows electrons from the anode to cross over to the cathode side, forming a junction.

This junction enables current flow in both directions, but only with a greater magnitude in the forward direction. This is because the valance band in the P-type material is much narrower than the conduction band in the N-type material, thereby providing a greater conduction current along the reverse bias region to suppress reverse current flow. The ratio of the forward current to the reverse current is known as the Zener Impedance. The BZV55C2V4 Zener diode can regulate voltage in a circuit because its Zener Impedance remains constant at higher reverse voltage levels.

Conclusion

The BZV55C2V4 is a single Zener diode used for voltage regulation in a variety of conditions ranging from memory structures to power supplies. The BZV55C2V4’s working principle is based on the PN Junction, and its Zener Impedance allows it to provide a regulated voltage to a circuit from a higher DC supply. As a reliable, efficient and highly versatile Zener diode, the BZV55C2V4 is an ideal choice for a wide range of applications in the electronics market.
