TVS (transient voltage suppressors) – Varistors, MOVs (metal oxide varistors) offer a cost-effective solution that provides over-voltage protection to sensitive equipment. V551DHB34 is a type of varistor or MOV (metal oxide varistor) that provides protection from high voltage transients or surges.

V551DHB34 is an exceptionally small overvoltage protection device and provides superior protection of electrical and electronic equipment against transient overvoltage caused by electrostatic discharge (ESD), lightning, and other transients. With its low leakage current, high surge protection, and low capacitance, it is highly suitable for a wide range of current-sensitive devices.

V551DHB34 varistors and MOVs provide a broad operating frequency response, effective transient protection, and excellent EMI/RFI (electromagnetic interference/radio frequency interference) performance. They also provide a high surge current and withstand repeated surges up to 50 A in the 8/20μS waveforms, and excellent performance up to 1000. V/μs waveforms.

V551DHB34 offers a comprehensive series of solutions for systems found in industrial, automotive, medical and telecommunications applications. It is designed specifically to provide superior protection for high-speed data lines such as PCMCIA cards, USB ports, high-speed video cables, and other sensitive wiring. It dramatically improves the protection and operation of medical equipment, automotive sensors, and other electrical and electronic systems.

V551DHB34 offers excellent overvoltage protection with low capacitance, low leakage current, and high surge current capabilities in a wide variety of sizes and voltage ratings. Its unique design utilizes a series of metal oxide varistors stacked in parallel combined with a current limiting device, such as a thermistor or varistor, to provide maximum surge protection.

The working principles of V551DHB34 can be broken down into two distinct parts: the surge protection circuit and the overvoltage protection circuit. In the surge protection circuit, the varistors absorb slow or fast high-voltage transients and limit the voltage to the desired level.

The overvoltage protection circuit uses a thermistor or, in some cases, a combination of a thermistor with a varistor to limit the voltage. The use of thermistors is preferred in high-temperature environments due to their superior speed of response in comparison to the other components. The thermistor limits the voltage until either the transient or normal operating voltage is reduced to the desired level.

V551DHB34 is a great choice for applications that require reliable, high-speed protection against transients resulting from ESD, lightning and other sources. Its low-leakage current, high surge protection, and low capacitance give it superior performance, making it a must-have for many electronic systems.
