TVS – Varistors, MOVs

TVS – Varistors, MOVs

Varistors, also known as voltage-dependent resistors, are semiconductor devices intended to provide non-linear electrical characteristics in circuits. Also known as voltage-dependent resistors (VDRs) they exhibit a high electrical resistance to changes in voltage. When the voltage applied to a varistor exceeds a certain threshold value, the resistance decreases sharply. This effect makes the device useful for protecting electronic circuits from high voltage transients such as those found in power supplies, automotive systems, and other industrial and consumer electronics.Metal oxide varistors (MOVs) are voltage-dependent resistors which can provide reliable over-voltage protection for a wide range of applications including DC-DC converters, solar inverters, electronic home appliances, and many more. The MOV has two components, namely a metal oxide layer and electrodes. The metal oxide layer is usually made up of zinc oxide, and the electrodes can be made of any metal. In operation, when an overvoltage is applied to the MOV, it shorts the metal oxide layer, creating a short-circuit across the two electrodes and allowing excess current to be safely diverted.The VE17P05750K is a type of MOV which is specifically designed for power supply, automotive, and industrial applications. It has an operating range of withstanding an 8/20µs pulse waveform of up to 7.5kV peak, with transients less than <5% of total voltage. The device is constructed of Zinc Oxide, with Nickel material contacts and is rated for a maximum power of 250V and 1.5 amps. This device also provides excellent overvoltage protection and high ESD ratings of up to 10,000 volts.This device is suitable for applications that require high transient surge capability and a fast response time such as DC-DC converters, AC-DC power supplies, automotive systems, and HVAC systems. The MOV is able to respond quickly to overvoltage conditions, in milliseconds or less, which makes it ideal for protecting sensitive and high-value electronics from damaging voltage spikes. This device also has a long lifespan, with an MTBF (Mean Time Between Failure) of >10,000 hours at rated voltage and power. This provides a cost-effective solution and safety assurance for product designers looking for over-voltage protection.In conclusion, the VE17P05750K is a metal oxide varistor that provides reliable over-voltage protection. This device is suitable for applications that require high transient surge capability and a fast response time. Its high ESD ratings, long lifespan, and cost-effectiveness make it an excellent choice for those who need reliable protection in their power supply, automotive, and industrial applications.
