The TRENCHSTOP™5 technology will be used as the basis of two families.

The first family, the HighSpeed 5 (H5), is available for the ease of use/plug and play replacement of existing IGBTs. It is a soft, high-speed IGBT requiring low design-in efforts.

The second family, the HighSpeed 5 FAST (F5), requires higher design effort, but offers the highest ever efficiency seen by an IGBT, for example more than 98% system efficiency has been observed in application measurements in a photovoltaic inverter using a H4 bridge.

Both are released with and without a 650V, anti-parallel, free-wheeling hyperfast silicon diode (FWD), where the hyperfast diode is an Infineon developed diode technology, from Infineon’s proprietary Rapid diode family.


  • Best-in-Class efficiency, resulting in lower junction and case temperature leading to higher device reliability
  • 50V increase in the bus voltage possible without compromising reliability
  • Higher power density design

Ultrafast Reverse Recovery Power Silicon Diodes

650 V Rapid 1 Diode

Infineon`s Rapid 1 diode family, with 1.35V temperature-stable forward voltage (V F), ensures the lowest conduction losses and by means of soft recovery keeps EMI emissions to a minimum. The devices are perfectly suited for Power Factor Correction (PFC) topologies, typically found in major home appliances, like air conditioners and washing machines.


  • 1.35V temperature-stable forward voltage (V F)
  • Highest S-factor for ultimate softness and low EMI filtering
  • Lowest I rrm to provide low turn-on losses on the boost switch
  • For applications switching between 18kHz and 40kHz

Key Applications

  • UPS
  • Air Conditioning System
  • Home Appliance
  • Welding

650V Rapid 2 Diode

The Rapid 2 diode family is designed for applications switching between 40kHz and 100kHz by offering low reverse recovery charge (Q rr) and time (t rr) to minimize the reverse conduction times attributed to the power switch turn-on losses and thus providing maximum efficiency.


  • Lowest reverse recovery charge (Q rr): forward voltage (V F) ratio for BiC performance
  • Low reverse recovery time (t rr)
  • Lowest I rrm to provide lowest turn-on losses on the boost switch
  • Designed for applications switching between 40kHz and 100kHz

Key Applications

  • Telecom
  • Server
  • PC Power
  • UPS
  • Welding
  • Adapter
