Vishay Intertechnology Inc. (NYSE:VSH) is one of the best performing semiconductor stocks so far in 2026.
On May 13, Vishay Intertechnology introduced four new series of 3000 W surface-mount transient voltage suppressors/TVS housed in the new DFN6546A package with wettable flanks
The rollout includes the Automotive Grade T3KNxxA and T3KNxxCA series, which are AEC-Q101 qualified and support high-temperature operation up to +185°C. For industrial applications, the 3KDFNxxA and 3KDFNxxCA series meet the LL15i Industrial Reliability Qualification. The DFN6546A package features a compact 6.5 mm x 4.6 mm footprint and a low typical profile of 0.88 mm.
It is footprint-compatible with the traditional TO-277A package but delivers twice the power dissipation with a 20% lower profile. Compared to standard DO-214AB packages, the new design offers the same 3000 W power dissipation while reducing total component volume by 76%. Designed to protect sensitive electronics from voltage transients, the unidirectional and bidirectional diodes provide clamping capabilities up to 137 V.
