Next-gen SiC diode targets renewable energy, EVs
Wolfspeed, A Cree Company, has introduced the 5th generation (C5D) 1700V SiC Schottky diode, which is optimized for renewable energy, industrial power and electric vehicle charging applications including solar power and wind turbine inverters, off-board chargers and uninterruptible power supply (UPS). The 1700V C5D is commercially available in both bare die and package formats, providing designers […]
Don’t get burned about LED UV
Another myth busted: You needn’t worry about ultraviolet light coming from ordinary LED bulbs. We recently checked a batch of LED bulbs for the amount of blue light they gave off. This effort came in response to claims from some in the alternative medicine crowd that LED bulbs gave off inordinate amounts of unhealthy blue […]
New 1.2-kV SiC Schottky diodes feature more creepage and clearance
Wolfspeed, a Cree Company, has expanded its C4D family of 1200V SiC Schottky diodes to introduce three new products in a TO-247-2 type package. The increased spacing between the two leads provides more than twice the creepage and clearance distance compared to standard TO-247-3 and TO-220-2 packages. “Improved creepage distance makes the C4D family expansion […]

RF design engineers are now able to build more efficient broadband power amplifiers for commercial and military wireless […]
GaN HEMT RF power devices handle 250 W, work up to 3 GHz
Wolfspeed, A Cree Company and a leading global supplier of GaN-on-SiC high electron mobility transistors (HEMTs) and monolithic microwave integrated circuits (MMICs) with best-in-class reliability, has extended its family of 50V unmatched GaN HEMT RF power devices by adding a 250W part with a frequency range up to 3.0GHz and the highest efficiency of any comparably-rated […]
DOE awards $30 million to advance new class of high-performance power converters
The U.S. Department of Energy’s (DOE) Advanced Research Projects Agency-Energy (ARPA-E) today announced $30 million in funding for 21 innovative projects as part of the Creating Innovative and Reliable Circuits Using Inventive Topologies and Semiconductors (CIRCUITS) program. CIRCUITS project teams will accelerate the development and deployment of innovative electric power converters that save energy and give the United States a critical […]
SiC MOSFET reference design details totem-pole PFC topology hitting 98% efficiency
Wolfspeed, a Cree Company, has advanced the development of high efficiency data center power supplies through the implementation of an innovative totem-pole PFC topology that employs its latest low-inductance SiC MOSFETs to exceed an 80+ Titanium rating, which is critical for reducing the overall power consumption for data centers, estimated to be more than 70 […]
50-V GaN MMICs handle D-Day radar apps
Wolfspeed, A Cree Company has introduced two new GaN MMICs, the first 50V GaN devices specifically designed for S-band radar (2.7–3.5GHz) applications. These new 50V GaN MMICs enable radar systems designers to reduce time to market with a less costly, less complex, 50V power amplifier line-up, while delivering the most efficiency possible. With a best-in-class combination […]
