Dual element transient voltage suppressors

Circuit & System Protection
Offering design engineers the ultimate in high density circuit protection, AVX introduced a dual-element 0405 MultiGuard multilayer ceramic TVS array. This line of surface mount chips offer the equivalent of two separate 0402 varistors, or four back-to-back diodes with two EMI capacitors. The MultiGuard Series chips are based on AVX's multilayer varistor technology, providing bi-directional ESD protection, EMI attenuation and sub-nanosecond response time.
Smaller size chips are increasingly being specified by designers faced with densely packed circuit boards in next-generation products. The fact that AVX can offer the smaller size of an 0405 dual-element chip array with high quality plated terminations makes this product ideal for use in miniature systems.
The miniature MultiGuard Series 0405 chip arrays are available in 5,6, 14 and 18 V, with a 0,02J energy rating, and a typical capacitance range from 40 pF at 14 V and 18 V to 360 pF at 5,6 V. The 0405 chips are rated for operation over -55 to +125°C.
