650V TRENCHSTOP™ 5 Technology
The IKW40N65WR5 combines a 650V blocking capability with low conduction and switching losses. Infineon specifies a low VCE(sat) of approximately 1.4V, supporting efficient operation in high-power switching circuits.
Integrated Monolithic Diode
The WR5 device uses reverse-conducting IGBT technology with an integrated monolithic diode optimized for applications such as zero-current-switching converters. This provides the IGBT and reverse-current path within a single power-semiconductor package.
High-Speed Power Switching
Infineon positions the TRENCHSTOP™ 5 WR5 technology for switching frequencies in the approximately 20kHz to 60kHz range. Its combination of low VCE(sat), low switching losses and temperature-stable behavior makes it suitable for high-efficiency power conversion.
