VS-UF Series Ultrafast Diodes Modules

Ultra-fast Diodes modules in the SOT-227 package offer a wide range of current ratings and lower thermal resistance from Vishay

Image of Vishay Semiconductor/Diodes Division's VS-UF Series Ultra-fast Diodes ModulesVishay Semiconductor/Diodes Division's VS-UF insulated modules integrate two state of the art ultrafast recovery rectifiers in the compact, industry standard SOT-227 package. The diodes structure and its life-time control provide an ultra-soft recovery current shape, together with the best overall performance, ruggedness and reliability characteristics. Based on Vishay Fred Pt® and HEXFRED® ultra-fast diodes, these modules provide ultra-soft recovery characteristics with higher thermal efficiency versus previous generations.

These devices provide ideal solutions for high frequency applications. This isparticularly true in applications where the switching energy is not to be the predominant portion of the total energy. This includes areas such as in the output rectification stage of welding machines, SMPS, and DC/DC converters. Their extremely optimized, stored charge and low recovery current reduce both over dissipation in the switching elements (and snubbers) and EMI/RFI.
