Surface Mount MLV MLCV SMD 1608 Metric Multilayer Chip Metal Oxide Varistor MVR0603-8R0G 8V 30A For Surge Protection

DESCRIPTION

The MVR series is metal oxide based chip varistor for transient voltage suppression. They have non-linear voltage-current behavior, similar to zener diode. Multilayer structured varistor, however, shows superiority in electrical reliability than zener diode, since each grain exhibits small p-n junction. In addition, MVR series shows better electrical properties such as high clamping voltage and low leakage current.

APPLICATIONS

* Protection from transient voltage noise in all kinds of IC
* Protection from ESD, EFT and surge in power I/O port
* Replacement of zener diode

FEATURES

* Chip varistor provides high reliability on surface mounting
* Wide range of working voltage (VW = 5.6V˜30V)
* Good clamping ratio and low leakage current
* Electroplating of Ni and solder gives higher solderability
* Wide operating temperature (-55˜125°C )
* Various capacitance is available

Varistor vs. TVS Diode

ESD current has the rise time of sub-nanosecond, duration of tens of nanosecond, and its amplitude reaches over 10KV. So, the protecting device from ESD also needs fast response time.
TVS diode has a similar performance with that of LATTRON's varistor, in terms of response time and handling capacity. Which, however, shows inferiority in surge current, leakage current,
operating directionality, polarity, and miniaturization as shown in the table.
