Integrated Power Modules (IPM)
Semikron's SKiiP (Semikron integrated intelligent power) Modules combine IGBT modules, gate drive and cooling technology in one set-up and all components are perfectly matched. Final testing at the end of production, including a one hour burn-in test which ensures the highest reliability in the application.The SKiiPs are available in two product lines, SKiiP3 and SKiiP4. SKiiP3 operates safely and reliably with applications in a current range from 500A to 2400A both in 1200V and 1700V technology. SKiiP4 provides an incresed level of reliability with an extended junction temperature of up to a maximum of 175°C and an extended current rating. The current ranges from 1800A to 3600A, both in the 1200V and 1700V volatge classes. The elevated junction temperatures for the SKiiP4 became reliable with the introduction of Semikron's sintered technology.
