The VCAS04AP704R7LAT1A from Kyocera AVX is an Automotive Qualified Multilayer Varistor that has been designed to offer high voltage and current handling capabilities in conjunction with fast response times. It has an AC voltage rating of 52 V, a DC voltage rating of 70 V, and a clamping voltage of 190 V. This AEC-Q200 qualified varistor handles large voltage transients, thereby making it useful for applications where capacitance-sensitive circuits need to be protected against high energy and current. It ensures low insertion loss, low leakage current, and unsurpassed reliability compared to conventional diodes.

This RoHS-compliant varistor provides bi-directional protection with a multi-strike capability and exhibits sub-1 ns response times to electrostatic discharge (ESD) strikes. It is available in a surface-mount package that measures 1.6 x 0.8 x 0.9 inches and is ideal for RF circuits, sensors, antennas, data lines, Bluetooth, Ethernet (IEEE 802.3bw and IEEE 802.3bp), and radar applications.
