OnSemi NVXK2KR80WDT Vienna rectifier module

“Our modules employ the latest SiC technology to minimise losses and overall system volume, allowing designers to meet charging efficiency and space goals,”, claimed Onsemi general manager Fabio Necco. “By adopting the pre-configured modular format, designers are able to configure their designs faster, with lower design risk.”

Operation is with junctions up to 175°C.

  • NVXK2TR40WXT is a 1.2kV 40mΩ, 27A H-bridge
  • NVXK2TR80WDT is a 1.2kV 80mΩ 18A H-Bridge
  • NVXK2KR80WDT (pictured) is a 1.2kV 80mΩ 18A single-mosfet six-diode module for Vienna rectifiers

The bridges are aimed at dc-dc conversion in the on-board charger, with headroom for high voltage battery stacks, while the Vienna rectifier version is aimed at the power-factor correction stage of on-board chargers. “There will be six-pack and full-bridge modules in the near future to complete the SiC on-board charging portfolio,” according to the company.


OnSemi NVXK2KR80WDT SiC transfer moulded packagePackaging is dual-inline, top-cooled and has serial numbers for traceability. It is also Pb-free, and ROHS and UL94V−0 compliant.

“Creepage and clearance distances meet IEC 60664-1 and IEC 60950-1,” said On. “Additionally, the modules are qualified to AEC-Q101 and AQG 324 for automotive use.”
