600 V EF Series MOSFETs

Built on second-generation super junction technology, the Vishay Siliconix 600 V EF series of 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 ZVS/soft-switching topologies such as phase-shifted bridges and  LLC converter half bridges.  The SiHx21N60EF, SiHx47N60EF, and SiHx70N60EF increase reliability in these applications by offering a 10x lower 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. The devices' ultra-low on-resistance and gate charge translate into extremely low conduction and switching losses to save energy in high-power, high-performance switch mode applications.

Features and Benefits

  • Low reverse recovery charge (Qrr) increases reliability in zero voltage switching topologies
  • Ultra-low on-resistance and gate charge reduce conduction and switching loss
  • Offered in TO-220, TO-263, thin-lead TO-220F, TO-247AD, and TO-247AC packages
  • Withstand high energy pulses in the avalanche and commutation mode with guaranteed limits through 100 % UIS testing
  • RoHS-compliant and halogen-free

Applications

  • Switch mode applications including solar inverters, server and telecom power systems
  • ATX/silver box PC SMPs
  • Welding equipment
  • UPS
  • Battery chargers
  • Semiconductor capital equipment
