TVS - Varistors, MOVs are solid-state devices made of zinc-oxide that were implemented in order to protect circuits from lightning strikes and high surges but modern technology enables these devices to provide various components and devices protection against modest and high voltage or current transients.

VP3225K101R017 is an SMD fusible varistor (MOV) designed to provide overvoltage protection to sensitive electronics. It features a surface-mount design for automated soldering processes, making it suitable for circuit protection by storing varying amounts of high-surge energy to help ensure against voltage peaks. It is able to provide long term performance and reliability and has a wide operating temperature range of -55°C to 125°C.

VP3225K101R017 Application Field

VP3225K101R017 offers reliable surge protection for a variety of different applications, such as computers, servers, communication equipment, household appliances, consumer electronics, industrial equipment, automotive electronics, and solar modules. It provides a maximum continuous operating voltage of 16 VDC and peak surge current of 2750 Amps, making it suitable for protecting any type of equipment.

VP3225K101R017 Working Principle

The VP3225K101R017 is a bidirectional solid-state device with two distinct parts – a metal oxide film and a zinc-oxide element. The metal oxide film acts as a current regulator, controlling the flow of current to the zinc-oxide element. In the event of a surge, the metal oxide film will dissipate the excess current into the zinc-oxide element, thus limiting the damage to the protected device.

The zinc-oxide element acts as a buffer between the external power source and protected device, reducing the effect of the surge. The VP3225K101R017 is designed to absorb a large amount of current while sustaining little to no damage individually, which allows it to protect circuits from electrical transients that would otherwise cause serious damage to unprotected devices.

The VP3225K101R017 also features a fuse functionality, which is implemented by providing a conductive path within the device. In the event of an overvoltage or overcurrent condition, the fuse will protect the protected device by opening the current path and interrupting the flow of current.

Conclusion

The VP3225K101R017 varistor helps protect systems from overvoltage and surge currents and is suitable for a wide variety of applications. It features a surface-mount design for automated soldering processes and a wide operating temperature range of -55°C to 125°C. This makes it an ideal choice for providing reliable surge protection in a variety of different applications.
