TVS - Varistors, MOVs

V30MLA1210LWA is a varistor device used to protect circuits against transient overvoltage. It comes with either ceramic or metal oxide semiconductor technologies and can protect against surge voltage and lightning strikes. The working principle of the V30MLA1210LWA is quite simple, it is designed to absorb the extra energy from momentary overvoltages and redirect it into a safe discharge path. The device works by rapidly altering its electrical conductivity in response to the surge, thus allowing the greater than nominal voltage to be drawn away from the primary protected circuit. The device has been designed to survive such events thousands of times while still providing protection against them.
