onsemi’s FS7 IGBTs are available with a voltage rating of 1,200 V and current ratings ranging from 40 A to 160 A. There are three packages available in the portfolio with different costs and applications in mind. The standard TO247 3-lead device is preferred for lower power applications as seen with the 40 A and 60 A current ratings. For higher power applications, the power TO247 or TP247 packages should be considered. These packages have an absence of the typical mounting hole seen on the standard TO247 packages to accommodate larger die and to dissipate heat more easily. The TP247 3-lead devices range from 60 A to 140 A in the S-series and one 100 A device in the R-series. The last package is the TO247 4-lead device that includes an additional source pin for a 30% improvement in switching losses. The TP247 4-lead devices will only be available in the S-series since these devices are optimized for low switching losses in high-switching frequency power converters.
