Varistors, also known as voltage dependent resistors (VDRs), are components designed to protect other circuit elements such as electronics, circuits, and other components from excessive and damaging electrical energy. This is why it is also referred to as the voltage surge protector. Moving on to the topic of discussion, the article is about the EZJ-ZSV270DAK varistor. This varistor has a wide variety of application fields and a unique working principle.

EZJ-ZSV270DAK Application Field

The EZJ-ZSV270DAK varistor is a device that helps protect from transient overvoltages. It is mainly used in automotive applications such as powertrain controllers, power inverters, automotive batteries, etc. It can also be used in other applications like personal electronic devices and power supplies. The device has a voltage range of 270Vdc and an operating temperature of -65°C to 150°C which makes it suitable for various applications.

EZJ-ZSV270DAK Working Principle

The EZJ-ZSV270DAK varistor has a Siemens MOV construction which makes it an ideal device for providing protection against transient overvoltage. The basic principle behind the working of this device is as follows –

When there is an overvoltage or current spike, the device attempts to absorb the energy and reduce it to a safe level by clamping the voltage to the varistor’s breakdown voltage. This is done by creating a low resistance path for the current to flow through. As the current flowing through the device increases, the voltage across the varistor will increase as well. Once the peak voltage reaches the breakdown voltage of the device, the current will flow through the varistor and be dissipated. This will help protect the other components in the circuit from the high voltage.

The EZJ-ZSV270DAK varistor is a device that is used in many applications to protect against transient overvoltage. It has a wide variety of application fields and a unique working principle of voltage clamping. It is a great device to keep your electronics safe and functioning in the long run.
