Vishay recently released their new 600V EF Series of fast body diode n-channel power MOSFETs. With low reverse recovery charge and on-resistance, the Vishay Siliconix SiHx28N60EF and SiHx33N60EF increase reliability and save energy in industrial, telecom, computing, and renewable energy applications.

Built on second-generation Super Junction Technology, the 600V fast body diode MOSFETs 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 SiHx28N60EF and SiHx33N60EF increase reliability in these applications by offering a 10x lower reverse recovery charge (Qrr) than standard MOSFETs. This allows the devices to regain the ability to block the full breakdown voltage more quickly, helping to avoid failure from shoot-through and thermal overstress. In addition, the reduced Qrr results in lower reverse recovery losses compared to standard MOSFETs.

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


  • 600V, 33A maximum RDS(on) max of 98 mΩ
  • 600V, 28A maximum RDS(on) max of 123 mΩ
  • Based on E Series Super Junction technology
  • Fast body diode provides as much as 10x reduction in Qrr over the standard E Series MOSFET for lifetime control
  • Designed and developed for soft-switching topologies along with similar standard E Series on-resistance values
  • Scales of economy can be achieved within a system using EF Series throughout the design (in place of standard E Series MOSFETs with similar on-resistance) in the hard-switched topology
  • Package options include TO-220AB (SiHP33N60EF); TO-263 (SiHB33N60EF D2PAK); TO-247AC (SiHG33N60EF); and TO-220 (SiHF28N60EF FULLPACK)
