TVS, otherwise known as Transient Voltage Suppressors, are electrical components designed to protect a variety of circuits from excessive voltage changes. Varistors, MOVs, and the V68ZS20P model are all components in this field. This article examines the application field and working principle of the V68ZS20P.

The V68ZS20P is a multipurpose transient voltage suppression (TVS) diode designed to protect discrete circuitry from damaging ESD voltage transients. It works as an over-voltage protection device, clamping a high voltage of up to 4kV and absorbing energy released in the form of a current. This device is highly portable and suitable for use in many varieties of protection applications due to its advanced design. It is renowned for its high breakdown strength and excellent performance in various temperatures.

Varistors are typically used in circumstances where sudden, large voltage differences occur, and with a peak pulse power rating of 110 Watts, the V68ZS20P is an ideal choice for such a situation. It operates best with a peak reverse voltage of 420 volts. This makes it suitable for a wide range of applications, such as power electronics systems, consumer electronics, and automotive electronics. The low leakage current of this device is beneficial for applications where small leakage current is desirable.

As with other types of varistors, the V68ZS20P is a two-terminal, non-linear device. It contains a junction or diode which is formed from two different layers of semiconductor material. When the reverse applied voltage on the device exceeds the breakdown voltage, the p-n junction begins to conduct, leading to voltage clamping. This causes a sharp increase in the current, which can cause damage to the circuit. The device’s capacitance helps to reduce this current by absorbing the surge rather than passing it on.

MOV, of Metal Oxide Varistor, are high energy devices designed to provide surge protection and clamping of transient voltages. The MOV is installed as a component between two circuit nodes to shunt large surges and quickly dissipate the energy. With a high peak pulse current of 16kA per line, V68ZS20P has a robust encapsulation and therefore works effectively as a surge protector. It is able to react rapidly, clamping the voltage and preventing damage to the circuit.

In addition to its surge protection capabilities, the V68ZS20P has several additional features. For instance, its lead-free design makes it ideal for use in lead-free products and processes. The low power dissipation it offers makes it suitable for applications requiring a low thermal budget. Its high surge capability allows it to be used for a wide range of applications, including telecommunications and automotive systems.

Overall, the V68ZS20P is a robust and efficient varistor, designed to protect critical components from voltage surges. Its varistor and MOV designs give it the strength and speed of response required to handle large surges. The low power dissipation and lead-free design make it well-suited to a variety of applications. This makes the V68ZS20P an ideal choice for a variety of transient Voltage Suppressor designs.
