Vishay Intertechnology, Inc. has introduced three new devices in its new 600 V EF Series of fast body diode n-channel power MOSFETs. With low reverse recovery charge and on-resistance, the Vishay Siliconix SiHx21N60EF, SiHx47N60EF, and SiHx70N60EF with current ratings from 21- to 70-A increase reliability and save energy in industrial, telecom, computing, and renewable energy applications.

Built on second-generation superjunction technology, the 600 V fast body diode MOSFETs released today provide a complement to Vishay’s existing standard E Series components, expanding the company’s offering to devices that can be used in zero voltage switching (ZVS)/soft switching topologies such as phase-shifted bridges and LLC converter half bridges.

The 21-A SiHx21N60EF is offered in four packages, while the 47-A SiHx47N60EF and 70-A SiHx70N60EF are each available in two. The devices feature ultra-low on-resistance of 176 mΩ, 65 mΩ, and 38 mΩ, respectively, and low gate charge. These values translate into extremely low conduction and switching losses to save energy in high-power, high-performance switch mode applications, including solar inverters, server and telecom power systems, ATX/Silver box PC SMPS, welding equipment, UPS, battery chargers, and semiconductor capital equipment.
The devices are designed to withstand high energy pulses in the avalanche and commutation mode with guaranteed limits through 100 % UIS testing. The MOSFETs are RoHS-compliant and halogen-free. Samples of the new EF Series MOSFETs are available now. Production quantities will be available in Q2 2015, with lead times of 18 to 20 weeks for large orders. Pricing for U.S. delivery only starts at $3.21 in 1,000-piece quantities.
