Cree Raises The Bar With 1200V SiC Power Device

The company says it is introducing industry’s first fully qualified, production-ready all-silicon carbide power module


Cree is introducing the first commercially available all-SiC Cree power module, the CAS100H12AM1.

The new high frequency module, rated at 100A current handling and 1200V blocking, allows higher efficiency, compact and lighter weight systems that can result in lower total system costs compared to conventional silicon-based technologies.

“An all-SiC module with these specifications enables us to meet our transit customers’ demands for reduced size and weight of auxiliary power converters, while meeting efficiency and cost targets," says Fisal Al-Kayal, innovation and research engineer, Alstom Belgium Transport.

The module includes SiC MOSFETs and SiC Schottky diodes in a 50mm half-bridge configuration rated to 150°C maximum junction temperature.

The SiC components enable the module to be operated at exceptionally high switching frequencies that can reduce the size, weight and cost of the power conversion system. The new power module has demonstrated up to 100kHz switching frequency. Target applications include high power converters, industrial motor drives, solar inverters and uninterruptible power supplies.

“The 1200V, 100A dual module extends our existing discrete MOSFET and diode products into higher power applications," explains Mrinal Das, product marketing manager, Cree Power and RF. “The efficient switching characteristics of an all-SiC module should allow system designers to meet customer demands for reduced size, weight and cost of the end-system, while reducing global energy consumption. Already, Cree SiC power devices have eliminated an estimated one million metric tons of annual CO2 emissions – the equivalent to planting 95 million trees."

Parts are available for immediate shipping through Digi-Key Corporation and Mouser Electronics (CAS100H12AM1). Sample gate drivers are available upon request to Cree for module customers.



AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
