PowerPAIR®


Vishay Siliconix's family of dual asymmetric power MOSFETs


Vishay Siliconix's PowerPAIR®Vishay Siliconix is expanding its PowerPAIR® family of dual asymmetric power MOSFETs for low-voltage DC/DC converter applications. These new devices expand the series’ voltage and package footprint options, making Vishay the only supplier to offer 3 mm x 3 mm, 6 mm x 3.7 mm, and 6 mm x 5 mm PowerPAIR® form factors.

Devices in the Vishay Siliconix PowerPAIR® family help to simplify the design of highly efficient synchronous buck single and multiphase DC/DC converters by providing an optimized combination of two MOSFETs in a single package. Their asymmetric configuration improves performance by allowing the size of the low-side MOSFET to be increased for lower conduction losses. The combination of TrenchFET® Gen III technology and the asymmetric nature of the PowerPAIR® allows Vishay to achieve a maximum on-resistance down to 1.3 m Ω for the low-side synchronous MOSFET, almost 50% lower than in a comparable symmetrical device.

By giving designers two co-packaged MOSFETs, PowerPAIR® devices simplify PCB layouts and reduce parasitic inductance, which can help to reduce switching losses and improve efficiency. The new PowerPAIR® devices will help to promote more efficient use of power and space in a wide range of electronics, including notebook and desktop computers, servers, game consoles, set-top boxes, TV monitors, and modems.

Benefits
