MALVERN, PA — Vishay Intertechnology, Inc. (NYSE: VSH) introduced a new series of transient voltage suppressor diodes designed to reduce circuit board space requirements in automotive and industrial electronics while increasing power dissipation capabilities.
The company launched four series of 3000 W surface-mount transient voltage suppressors in a new DFN6546A package format aimed at applications including electric vehicles, industrial automation systems, and advanced driver assistance technologies.
Vishay stated the new package delivers higher power density in a smaller footprint compared with existing industry-standard packaging formats used in power electronics.
According to the company, the new DFN6546A package provides twice the power dissipation of comparable SMPC-packaged devices while reducing profile height by 20%. Compared with SMC-packaged components, the new devices maintain similar power dissipation while reducing package volume by 76%.
The Automotive Grade T3KNxxA and T3KNxxCA series are qualified under AEC-Q101 standards and support operating temperatures up to 185 degrees Celsius.
The company said the devices are intended to protect electronics from voltage spikes caused by lightning strikes and inductive load switching.
Potential automotive applications include advanced driver assistance systems, lidar, battery management systems, onboard chargers, traction inverters, infotainment systems, and electric power steering systems.
Industrial applications include robotics controls, automation systems, energy storage infrastructure, telecom equipment, medical devices, and server power modules.
Vishay also highlighted the package’s wettable flank design, which allows automated optical inspection during manufacturing without requiring X-ray inspection processes.
