TVS (Transient Voltage Suppression), Varistors, and MOVs (Metal Oxide Varistors) are three commonly applied types of electrostatic discharge (ESD) protection found in electronic circuits. The VDRS07H275AGE (previously known as the VTMS07H275AGE) is a Varistor, or Variable Resistor, that provides fundamental ESD protection and EMI (electromagnetic interference) filtering. It is a specific series of multilayer varistor, called MSR, designed for high reliability and improved protection.

Varistors are essentially two-terminal semiconductor devices with an elongated, rod-like body. They consist of two or more materials such as ceramic, metal oxide, or silicon, sandwiched between two metal plates. The two plates are connected to the ends of the wire and can be used to carry electric current. The core material has a unique variability of electrical behavior that allows it to disperse the incoming voltage in a controlled manner. This ability to limit and control the surge of voltage makes them useful for ESD and EMI protection.

The VDRS07H275AGE Varistor is designed for use in personal electronics, small industrial and medical applications. It has a diameter of 7mm and a rated voltage of 275V, making it ideal for medium-powered applications. It is approved by UL, RoHS, CE, and PSE, and carries an end-of-life rating of 20nC, demonstrating its robust construction and reliability.

The VDRS07H275AGE is designed to work by providing fast and efficient diversion of high voltage pulses. The varistor will clamp the excessive voltage to a safe and controllable level, allowing it to remain outside the range of specified operational voltage for the connected circuits. Depending on the rise and fall time of the pulses, as well as the current, the varistor has the capacity to limit excessive voltage, dissipate the power, and minimize the possibility of damage to the sensitive electronic components.

The VDRS07H275AGE is capable of providing superior performance in any environment. It is designed to deliver reliable protection against ESD pulses of 15KV, as well as protection from surges of > 20KV. With a maximum permissible operating voltage of 375V, it is also suitable for providing noise filtering in circuits with higher voltage signals. These features make the VDRS07H275AGE a versatile option for ESD and EMI protection in many applications.

TVS, Varistors, and MOVs are all important elements in the fabrication of electronic circuits, but the VDRS07H275AGE Varistor stands out as a superior option for ESD protection and EMI filtering for many applications. Its advanced construction and ability to disperse excessive voltage provide superior protection and reliability, making it an excellent choice for any circuit.
