FRED Pt® Ultrafast Rectifiers in SMP Package

Vishay's FRED Pt ultrafast recovery rectifier family offers eight 100 V and 200 V devices in the eSMP series SMP (DO-220AA) package, including the industry’s first to offer current ratings to 2 A. These rectifiers are able to increase power density by providing the high current ratings typically reserved for the SMA (DO-214AC) package in the smaller SMP package, which needs 24% less PCB space. The SMP package boasts ultrafast recovery times down to 14 ns, reduced Qrr to 10 nC, and soft recovery features, making this product ideal for automated placement.
