Transient Voltage Suppressors

Wed, 05/30/2001 - 11:55am
AVX Corporation introduces its MultiGuard® Series of bi-directional transient voltage suppressors in new, smaller case sizes, providing bi-directional ESD protection, EMI attenuation and subnanosecond response time. The 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.

Ideal for I/O lines in portable equipment and programming ports in cellular phones, the MultiGuard family devices may be used on any electronic PCB containing multiple TVS chips of the same voltage/energy rating. Available with standard working voltages of 5.6 V, 9 V, 14 V, and 18 V with 0.1 joule energy rating available. The MultiGuard arrays have a typical capacitance range from less than 225 pF to 825 pF. 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 75 pF), rated at >=18V/.05 joules.
