Image of KYOCERA/AVX Advantages of Multilayer Varistor Versus TVS Diodes - Size Reduction

Multilayer varistors can save up to 80% of the space of an equivalent TVS diode. Additionally, they replace the need for both a TVS diode and a capacitor in certain applications like an automotive communications Bus. There may be sensors or modules on the communications Bus that need circuit protection but also need EMI filtering capacitors, usually in the form of MLCCs. If the TVS diodes used on a communications Bus are uni-directional, two diodes will be needed, in which case an MLV would replace three diodes.
