KYOCERA AVX, a leading global manufacturer of advanced electronic components engineered to accelerate technological innovation and build a better future, released the new range of load dump varistors as an extension of its trusted TransGuard Automotive Series.
KYOCERA AVX TransGuard Automotive Series varistors are innovative, zinc-oxide-based ceramic semiconductor devices that provide bidirectional overvoltage protection and EMI/RFI attenuation in a single, space-saving SMT package qualified to AEC-Q200 and backed by more than 20 years of proven performance in an array of automotive electronics. Key features include a unique monolithic multilayer construction, nonlinear, bidirectional voltage-current characteristics, high-current and -energy-handling capabilities, multi-strike capabilities, and extremely fast, sub-nanosecond response times. They are also available with glass encapsulation for enhanced resistance against harsh environment hazards including acids, salts, and chlorite flux. Combined, these features enable TransGuard Automotive Series varistors to provide reliable, state-of-the-art circuit protection from voltage transients caused by ESD, induction motor loads, module load dump, and other disruptions, which is increasingly vital as the number of electronic systems deployed in automotive applications continues to grow

The new VCAS Series load dump varistors outperform competing solutions in terms of both energy handling & footprint size
The new TransGuard Automotive Series load dump varistors are characterized by higher peak current ratings than the rest of the series (2,000A), which make them even more effective at providing reliable protection against high-energy automotive load dump transients. Load dump pulses simulate a sudden battery disconnection from the alternator and cause the alternator to generate an overvoltage impulse that can damage sensitive ICs, which are also increasingly common in today's automotive designs.
