Varistors, also known as voltage dependent resistors, are two-terminal non-linear electronic components with a wide range of applications. One particular type of varistor is the VGAS222026Y570DP, a varistor made of a ceramic-oxide based semiconductor material. This article will discuss the application field and working principle of the VGAS222026Y570DP and its relevance to the TVS (transient voltage suppressor) family of devices.

Application Field Of VGAS222026Y570DP

The VGAS222026Y570DP is a type of varistor rated at 12volts and capable of handling up to 5amp of current. This varistor is primarily used to protect against overvoltage and overcurrent in low voltage electronic circuit. Specifically, it is used in applications such as overvoltage and overcurrent protection, power supply filtering, surge absorption, commutator protection, surge absorption for relay control, and other related applications. Additionally, this varistor is designed in such a way as to reduce EMI (electromagnetic interference) and help maintain the integrity of the circuit.

Working Principle Of VGAS222026Y570DP

Varistors are two-terminal components that work on the principle of voltage and current level sensing. When a particular voltage or current is exceeded, the resistance of the varistor changes drastically. This is a result of applied voltage inducing movement of charge carriers (electrons) within the material of the varistor. The VGAS222026Y570DP in particular, features a ceramic-oxide semiconductor material within its design. As a result, it has a very low voltage clamping range, allowing it to stop overvoltage and overcurrent in even lower voltage circuits.

VGAS222026Y570DP As Transient Voltage Suppressor/Surge Arrester

The VGAS222026Y570DP is part of the larger class of varistors called Transient Voltage Suppressors (TVS). TVS-based varistors are used in situations where transient currents need to be suppressed or arrested. This could be due to overvoltage, electrostatic discharge, or induced current from other sources. The VGAS222026Y570DP is capable of protecting against such transient currents due to its low voltage clamping range. Additionally, it possesses high current absorption capability which allows it to quickly suppress such current surges and protect the system from damage.

Conclusion

In conclusion, the VGAS222026Y570DP is a two-terminal device based on a ceramic-oxide semiconductor material. This varistor is mainly used to protect low voltage electronic circuits from overvoltage and overcurrent and can be classified under the TVS (transient voltage suppressor) family. Its low voltage clamping range and high current absorption capability makes it suitable for suppressing transient currents and protecting the system from damage.
