Varistors Provide Reliable ESD Protection in Capacitance-Sensitive Applications

FOUNTAIN INN, S.C. — AVX Corporation has released the new Antenna PowerGuard Series varistors, an ultralow capacitance extension of its reliable AntennaGuard range with new voltage, capacitance, and energy ratings. Antenna PowerGuard Series varistors exhibit high current and energy handling capabilities, low insertion loss, low leakage current, and unsurpassed reliability compared to diode options. These advantages, combined with AEC-Q200 qualification, bidirectional overvoltage protection, EMI/RFI attenuation, fast response times (<1nS), and multi-strike capabilities make the small SMT packaged series ideal for use in RF and optic circuit, sensor, high-speed and data line, antenna, radar, Bluetooth, Ethernet, and other capacitance-sensitive applications across the automotive, industrial, and commercial markets.

The new Antenna PowerGuard Series varistors are currently available in two case sizes (0402 and 0603), three working voltages (18, 24, and 30VDC), and three capacitance ratings (1.5, 2, and 3.3pF). The series features a 25kV ESD rating, energy handling capabilities spanning 0.02 – 0.04J, and peak current handling capabilities spanning 1 – 3A, and is rated for use in operating temperatures ranging from -55°C to +125°C with no derating. Antenna PowerGuard Series varistors also meet 48VDC jump start requirements, are AEC-Q200 qualified and RoHS compliant, and offer excellent solderability thanks to nickel-barrier, 100% tin (Ni/Sn) terminations. Parts are shipped on 7” or 13” reel, and lead-time for the series is currently 14 weeks.
