Infineon Technologies AG introduced the new 650 V TRENCHSTOP 5 WR6 family.

The family comes in a TO-247-3-HCC package and offers a broad portfolio comprising 20 A, 30 A, 40 A, 50 A, 60 A and 70 A current ratings. 

The TRENCHSTOP 5 WR6 switches provide low conduction losses (30 A, 1,45 V at 25°C) as well as low switching losses (30 A, 1,55 mJ at 175°C). They feature a minimal saturation voltage (V CE(sat)) of 1,45 V and a monolithically integrated diode with enhanced forward voltage for the target applications. 

The devices are developed to easily be used to replace previous technologies like Infineon’s TRENCHSTOP 5 WR5, HighSpeed 3 H3, as well as technology from other developers. 

The new TO-247-3-HCC housing of the WR6 family increases the creepage and clearance distances thus improving the isolation voltage rating. 

The TRENCHSTOP 5 WR6 family enables more reliable system designs that are resilient to contamination and condensation which sometimes occur at AC outdoor units. 

The family is optimized for power factor correction (PFC) for residential and commercial air conditioning systems as well as welding applications.

According to Infineon, the TRENCHSTOP 5 WR6 reduces the total cost of ownership with less failure rate while it also enables higher switching frequency in application.
