Infineon TRENCHSTOP 5 WR6 Family Improves Isolation Voltage Rating

Article By : Infineon Technologies AG

Infineon's 650V TRENCHSTOP 5 WR6 family is optimized for PFC for residential and commercial air conditioning systems.

Infineon Technologies AG has launched the new 650V TRENCHSTOP 5 WR6 family in a discrete housing. Available in a TO-247-3-HCC package, the family offers a broad portfolio comprising 20, 30, 40, 50, 60, and 70A current ratings and can easily be used for replacing previous technologies like Infineon’s TRENCHSTOP 5 WR5 and HighSpeed 3 H3 as well as competitor technologies. The devices are optimized for power factor correction (PFC) for residential and commercial air conditioning systems as well as welding applications.

The TRENCHSTOP 5 WR6 switches provide very low conduction losses (30A, 1.45V at 25°C) as well as lowest switching losses (30A, 155mJ at 175°C). They feature a very low saturation voltage (VCE(sat)) of 1.45V and a monolithically integrated diode with optimized forward voltage for the target applications. This results in best-in-class performance while enabling a low BOM cost. Additionally, the device leverages the performance advantage of the TRENCHSTOP 5 WR5 series, the predecessor to the TRENCHSTOP 5 WR6 series.

The new TO-247-3-HCC housing of the WR6 family increases the creepage and clearance distances thus improving the isolation voltage rating. With this, the product family enables more reliable system designs that are resistant against contamination and condensation, which often occur at AC outdoor units. The TRENCHSTOP 5 WR6 reduces the total cost of ownership with less failure rate while it also enables higher switching frequency in application.
