The SKiM306GD12E4 is a 1200V 300A 6-pack configuration with 3 separated half bridges for high reliability operation.

Semikron uses silver sinter technology to increase the durability and pressure contact to obtain a solderless power module.

The SKiM306GD12E4 is based on IGBT4 technology from Infineon and CAL4-F diode. Semikron has designed the CAL4-F diode to be very efficient with the IGBT4. The diode has been designed to obtain a good resistance to environment in a non hermetic package and benefits from the expertise of Semikron in the irradiation to reduce the carrier lifetime.

The SKIM 63 module is a no baseplate design. The DBC substrates are directly assembled on the heatsink to enhance the power management and reduce the height of the module.

The sinter layer is very thin to decrease the thermal resistance and limit the cost of silver material. With a cost close to a classic SAC solder, the sintered joint increases the service life.

The report presents a deep technology analysis of the packaging and of the transistors and diodes structures.

It also includes production cost analysis and an overall comparison with Infineon FS100R12PT4 1200V 100A.
