Automotive varistors deliver lowest leakage current available

October 10, 2011 // By Christoph Hammerschmidt
Passive component manufacturer AVX Corporation has developed a varistor designed for general ESD protection use in automotive circuits, including CMOS, bi-polar, and SiGe based systems. The AEC Q200-qualified Automotive StaticGuard Series varistor delivers low capacitance and the lowest specified leakage current available in the industry. The product is ideal for high-speed signal lines, the company says.

The varistor series provides bi-directional transient voltage protection in the on-state and very high EMI/RFI attenuation in the off-state, while offering an ESD rating up to 15kV, the vendor advertizes. Available in miniature 0402, 0603, and 0805 case sizes, the RoHS-compliant Automotive StaticGuard Series devices are suited for general-purpose drives, general-purpose logic, transceiver chips, and sensor applications

Typical pricing for the Series ranges from $0.04 to $0.09 in volume with a lead time of 12 weeks.
