This release in:

MALVERN, PENNSYLVANIA —Nov. 14, 2011 — Vishay Intertechnology, Inc. (NYSE: VSH) is expanding its PowerPAIR® family of dual asymmetric power MOSFETs for low-voltage DC/DC converter applications with new devices that expand the series’ voltage and package footprint options, making Vishay the only supplier to offer 3 mm by 3 mm, 6 mm by 3.7 mm, and 6 mm by 5 mm PowerPAIR form factors.

Expanding the portfolio with new footprint options are the 30 V SiZ300DT in the PowerPAIR 3 x 3 and the SiZ910DT in the PowerPAIR 6 x 5. The SiZ300DT targets DC/DC applications handling currents of 10 A and under, while the SiZ910DT is suitable for applications above 20 A. The PowerPAIR 3 x 3 has approximately one third the area of the PowerPAIR 6 x 5.

Three new devices in the PowerPAIR 6 x 3.7 are all industry firsts, and with the previously released SiZ710DT expand the voltage range in this form factor from 20 V up to 30 V. The new SiZ728DT is the first 25 V PowerPAIR 6 x 3.7 device, while the SiZ790DT is the first device in this form factor with an on-board Schottky diode. The SiZ730DT is debuting as the lowest-RDS(on) 30 V PowerPAIR 6 x 3.7 device.

The following table provides detailed specifications for all five new devices, as well as the SiZ710DT. Information on Vishay’s complete portfolio of PowerPAIR MOSFETs can be found at http://www.vishay.com/mosfets/powerpair-package/.

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 PowerPAIR allows Vishay to achieve a maximum on-resistance down to 3 m? 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.

Samples and production quantities of the new PowerPAIR devices are available now, with lead times of 12 to 14 weeks for large orders.

Vishay Intertechnology, Inc., a Fortune 1000 Company listed on the NYSE (VSH), is one of the world's largest manufacturers of discrete semiconductors (diodes, MOSFETs, and infrared optoelectronics) and passive electronic components (resistors, inductors, and capacitors).
