Vishay — SiR5x0DP TrenchFET® Power MOSFETs

Vishay SiR5x0DP TrenchFET® Power MOSFETs

Power MOSFETs offer high efficiency in secondary-side converter applications

New products in the fifth generation of the Vishay family of TrenchFET® power MOSFETs provide superior performance and efficiency in applications such as the secondary side of dc-dc converters in servers and telecoms infrastructure.


The 150 V SiR570DP, 100 V SiR510DP, and 80 V SiR580DP offer the industry’s best figure-of-merit for the product of on-resistance and gate charge: in the case of the SiR510DP, as much as 78% better than typical competing products. This superior figure-of-merit enables power-system designers to reduce switching and conduction losses, and so to achieve higher conversion efficiency.


The SiR5x0DP products are ideal for use in a range of power functions, including:

  • Input inrush switches
  • ORing
  • Primary-side switching
  • Synchronous rectification
  • Hot-swap switching
  • Motor-drive control


  • Low output capacitance
  • PowerPAK® SO-8 package
  • Operating-temperature range: -55°C to 150°C


  • Servers
  • Power tools
  • Power adaptors
  • Telecoms equipment
  • Industrial systems
