MultiGuard Transient Voltage Suppressors

Thu, 06/28/2001 - 7:33am
AVX Corp. introduces its MultiGuard® Series of bi-directional transient voltage suppressors in new, smaller case sizes, providing bi-directional ESD protection, EMI attenuation and sub nanosecond response time. Offering electronic circuit design engineers a reliable transient voltage protection solution, MultiGuard chips are now available in 0405 two-element, 0508 two and four-element and 0612 four-element case sizes. AVX's MultiGuard products consume less than half the PCB real estate required for the equivalent number of discrete chips. This size advantage, coupled with the savings associated with placing only one chip, makes MultiGuard a cost-effective product for ESD protection.

MultiGuard chips (0405, 0508 and 0612 sizes) enable circuit designers to place transient voltage suppression devices on high density PCBs in products, such as cellular phones, pagers and digital cameras. These TVS arrays provide ideal alternatives where multiple lines require ESD protection. These two-element and four-element arrays offer design engineers effective alternatives to the more time-consuming and expensive placement of multiple discrete components. That translates into higher productivity, lower inventory costs and more available PCB space.

Ideal for I/O lines in portable equipment and programming ports in cellular phones, the MultiGuard family of devices may be used on any electronic PCB containing multiple TVS chips of the same voltage/energy rating. Standard working voltages of 5.6V, 9V, 14V, and 18V with 0.1 joule energy ratings are available. The MultiGuard arrays have a typical capacitance range from less than 225pF to 825pF. These transient voltage suppressor arrays are rated for operation over the full temperature range from -55°C to +125°C. A StaticGuard version is also available (low capacitance at less than 75pF), rated at </=18 V/.05 joules.
