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 […]

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 […]
Power modules pass high humidity/temperature/voltage tests for extreme environments
Wolfspeed, a Cree Company, has released the industry’s first power module that passes the harsh environment qualification test for simultaneous high-humidity, high-temperature and high-voltage conditions. This reliability benchmark enables system designers to use this device in outdoor applications such as transportation, wind, solar and other renewables where extreme environmental conditions have historically challenged safe device […]
LED delivers more than 2,500 lumens 6mm light emitting surface (LES)
Cree, Inc. introduces the XLamp® XHP50.2 LED, which delivers up to seven percent more lumens and 10 percent higher lumens-per-watt (LPW) than the first generation XHP50 LED in the same 5.0 mm x 5.0 mm package.
