45mm SiC Six-Pack Power Module
Cree’s CCS050M12CM2 is the industry’s first commercially available silicon carbide (SiC) six-pack power module in an industry standard 45mm package. When replacing a silicon module with equivalent ratings, Cree’s six-pack module can reduce power losses by 75 percent, which leads to an immediate 70 percent reduction in the size of the heat sink or a 50 percent increase in power density.
The new six-pack SiC module unlocks the traditional design constraints associated with power density, efficiency, and cost, allowing designers to create high performance, reliable, and low cost power conversion systems.
When compared to state-of-the-art silicon modules, the SiC 1.2 kV, 50A modules deliver performance equivalent to silicon modules rated at 150A. The efficient switching of the SiC module also allows for significantly less derating than silicon IGBTs. This enables significantly higher frequency operation, which both increases fundamental output frequency and reduces passive component size in applications like motor drives, solar inverters, uninterruptible power supplies, and industrial power supplies.
Even when designers simply substitute Si modules with SiC in motor drive applications, the improved performance of SiC reduces power losses, leading to reduced cooling requirements and, in turn, to a reduction in size, weight,
The CCS050M12CM2 six-pack modules from Cree are the industry’s first commercially available silicon carbide (SiC) six-pack power module in an industry standard 45mm package and are available for immediate shipping through Digi-Key Corporation and Mouser Electronics.
Infineon AG 5th Gen 650V SiC Diodes
The new SiC diode technology of Infineon combines a couple of innovations – smallest die area and thus lowest cost for a given power handling capability, optimized trade-off between static and dynamic losses and the worldwide first implementation of thin wafer technology for SiC devices.
This new chip technology will soon be implemented in a newly developed packaging platform offering small footprint and very low stray inductance compared to existing solutions. Thus, it is an optimized combination of best in class chip technology with the optimum package in order to utilize the benefits offered by the chip to full extent.
The new product addresses the trend towards thinner chips in SiC in order to remove the contribution of the substrate to the on resistance as well as the issue of high stray inductance in standard packages which limits the high frequency performance of ultrafast SiC components ad acts as source of unwanted EMI problems.
Infineon developed a grinding process for SiC wafers as well as a high temperature technology to form a reliable and high performing ohmic backside contact after grinding without affecting the at this stage in the process chain

already finished front side structure. The resulting chip will be implemented in a newly developed low profile SMD package offering lowest stray inductance by multiple short thin wire bond connections to the terminals and pin free connection to the PCB.
Soraa GaN on GaN LEDs
The main advantage of Soraa’s GaN on GaN (Gallium Nitride on Gallium Nitride) LED material is that it allows reliable operation at very high current densities. It has 1000x fewer defects than conventional LEDs, which have GaN layers on cheaper foreign substrates like sapphire, silicon carbide, or silicon.
This enables Soraa LEDs to emit 10x more light per unit area of LED material than conventional LEDs. GaN on GaN’s optical transparency and high thermal and electrical conductivity also enable a very robust, simple LED design that delivers maximum light output and performance.
In February 2013, Soraa announced world-record performance from its GaN on GaN LEDs. For applications that require very high light output from tiny form factors – e.g. MR16 lamps – Soraa’s Gen 2 LEDs deliver unprecedented performance and colour rendering. The SORAA PREMIUM 2 and VIVID 2 LED MR16 lamps use these Gen 2 LEDs.
