Vishay Intertechnology Inc. (Malvern, PA) announced that it is adding to its transient voltage suppressor (TVS) families with what is claimed to be the industry’s first such single-chip devices rated for breakdown voltages up to 540V. The new additions increase the available maximum breakdown voltage from 440V to 540V in Vishay’s P4KE, P6KE and 1.5KE480 axial-leaded TVS families, and from 220V to 540V in the surface-mount P4SMA, P6SMB and 1.5SMC families.
Providing transient voltage protection for high-intensity discharge lighting and lighting ballast applications, the Vishay TVS devices are built on a patent-pending process that yields improved surge capability, lower leakage currents and improved voltage clamping for high-voltage applications. Enhanced performance in a single chip also allows designers to lower costs and reduce board space by implementing one device, rather than two, for high-voltage protection.
Samples and production quantities of the new extended-range TVS devices are available now, with lead times of eight weeks for larger orders. Pricing starts at about $0.10 in 100,000-piece quantities.
