500 V High-Voltage MOSFETs Use Gen II Super Junction Technology

Vishay Intertechnology, Inc. announced the addition of 11 devices to its 500 V series of high-voltage MOSFETs optimized for operation in switch mode power supplies (SMPS) to 500 W. Featuring the same benefits of extremely low conduction and switching losses as the company's E Series 600 V and 650 V devices, the Vishay Siliconix MOSFETs were developed to assist customers in achieving higher performance/efficiency standards such as the stringent 80 PLUS efficiency standards required for certain high-performance consumer products, lighting applications, and ATX/silver box PC SMPS.

Built on second-generation Super Junction Technology, the 500 V MOSFETs released today provide a high-efficiency complement to Vishay's existing 500 V D Series components based on standard planar technology. The 12 A to 20 A devices feature low on-resistance from 190 mW to 380 mW and ultra-low gate charge of 22 nC to 45 nC. This combination results in a very favorable figure of merit (FOM) for power conversion applications.

The devices' low on-resistance also helps improve power density, while their faster switching speeds increase efficiency in typical hard-switched topologies such as power factor correction (PFC), two-switch forward converters, and flyback converters.

The RoHS-compliant devices are designed to withstand high energy pulse in the avalanche and commutation modes with guaranteed limits through 100 % UIS testing. Samples and production quantities of the new 500 V power MOSFETs are available now, with lead times of 16 to 17 weeks. Pricing for U.S. delivery only starts at $2.30 per piece.
