The VCAS04AP701R5YAT1A from Kyocera AVX is a Multilayer Varistor that has been optimized to offer high current and energy 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 350 V. The AEC-Q200 qualified varistor can handle larger voltage transients making it useful for applications where capacitance-sensitive circuits need to be protected against high energy and current. It has a low insertion loss, and low leakage current, and provides unsurpassed reliability compared to diodes. This RoHS-compliant varistor also ensures 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 x 0.5 x 0.6 inches and is ideal for Bluetooth, ethernet (IEEE 802.3bw and IEEE 802.3bp), antennas, sensors, RF circuits, data lines, and radar applications.
