PowerPAIR® Dual-MOSFETs Vishay PowerPAIR® Dual-MOSFETs combine optimized combinations of MOSFETs in one compact package. The co-packaged Vishay PowerPAIR Dual-MOSFETs use less space and offer increased performance over separate discretes. By having the two MOSFETs already connected inside the PowerPAIR package, layouts are made easier and parasitic inductance from PCB traces are reduced, increasing efficiency.
