TVS - Varistors, MOVs is a type of electrical component that has a wide range of uses and implementations. The ERZ-U23JP112 is a product line from the manufacturer EPCOS that is part of this family. This application field and working principle will be addressed in this article.

The ERZ-U23JP112 is a type of surface mount, hybrid suppression device composed of a varistor, an MOV (Metal Oxide Varistor) and suppression capacitors. It is specially designed to provide overvoltage protection from transient overvoltages and surges in high-speed, high-frequency applications. The device is rated for 125 volts maximum peak impulse voltage and provides a rated clamping voltage of up to 140 volts. It has a wide range of operating temperature ranges from -40 to +85°C and can be used in both DC and AC operating modes.

Varistors are also known as voltage-dependent resistors or VDRs. They are widely used in circuit protection because of their ability to suppress transient overvoltages in high frequency, high speed applications. Varistors are made of metal-oxide semiconductor material, and when subjected to a higher voltage, they act as a resistor and reduce the flow of current. This allows them to absorb the surge or transient voltages during an overvoltage event and protect the circuit.

MOVs are similar to varistors in that they are also made of metal-oxide semiconductor material and they also act as a resistor to reduce the flow of current and protect the circuit. They differ in that they are not voltage dependent, meaning they do not become more resistive when exposed to higher voltages. Instead, they act as a voltage clamp and have a predetermined voltage level that will not be exceeded and will therefore act to protect the circuit.

The ERZ-U23JP112 is a combination of both varistors and MOVs. It combines the surge protection benefits of a varistor with the clamping protection benefits of an MOV. The two devices are connected in series, and the combined voltage protection offered by the two is greater than that of either one individually. The combination also provides better current-limiting characteristics for high-speed, high-frequency applications.

The ERZ-U23JP112 is a versatile and reliable component for overvoltage protection and surge suppression. It can handle a wide range of voltages and is suitable for both DC and AC operating modes. Its hybrid design makes it an ideal choice for applications that require both surge and clamping protection, such as those in telecommunications, industrial, automotive and consumer electronics.

The ERZ-U23JP112 is an important component for any system that demands reliable performance and long-term reliability. Its combination of varistor and MOV protection makes it an ideal choice for high-speed, high-frequency applications and provides a wide range of protection for these applications. The device is highly reliable in its performance and can provide effective protection for overvoltage and surge events.
