Cree 1200V Z-Rec family of silicon carbide schottky diodes offers higher performance at lower cost for power conversion apps
DURHAM, USA: Cree Inc. announced a new family of seven 1200V Z-Rec silicon carbide (SiC) Schottky diodes optimized for price and performance and available in a range of amperages and packages. Cree is advancing the adoption of silicon carbide power devices into mainstream power applications by introducing a comprehensive family of SiC diodes with a wide range of amperage ratings and package options.
“In order to develop the next generation of power electronics, design engineers are looking for the unique performance advantages of SiC Schottky diodes – zero reverse recovery losses, temperature-independent switching losses, higher frequency operation – all with a lower EMI signature,” said John Palmour, Cree co-founder and chief technology officer, Power and RF.
“This new family of diodes allows a higher current density and increased avalanche capability over previous generation SiC Schottky diodes with no penalty in performance. Cree’s recent innovations in device design and commitment to continuous process improvement are allowing us to offer significantly higher amperage ratings at lower cost per amp.”
Cree Z-Rec diodes feature zero reverse recovery, resulting in up to a 50 percent reduction in switching losses versus comparable silicon diodes. They also exhibit consistent switching performance across their entire temperature range, which simplifies circuit design and reduces the need for complex thermal management.
When used in conjunction with Cree’s recently-introduced 1200V SiC power MOSFETs, these SiC Schottky diodes enable the implementation of all-SiC power electronic circuits with the capability to operate at up to four times higher switching frequencies when compared to conventional silicon diodes and IGBTs.
This enables a reduction in the size, complexity and cost of inverter circuitry, while achieving extremely high system efficiency. Finally, this new family has the additional benefits of higher surge ratings and avalanche capabilities than the previous generation of SiC Schottky diodes, helping to increase overall system reliability.
These devices are ideal as boost diodes and anti-parallel diodes in solar inverters and 3-phase motor drive circuits, as well as in power factor correction (PFC) boost circuits in power supplies and UPS equipment. They can also be used in applications where engineers typically parallel many devices to address higher power requirements.
Devices now released are rated for 2A[C4D02120x], 5A[C4D05120x], 10A[C4D10120x], 20A[C4D20120x] and 40A[C4D40120x]. Dependent on amperage ratings, the parts are available in standard or fully-isolated TO-220 and standard TO-247 packages. Check with Cree for availability of devices in die form.
These new Z-Rec 1200V Schottky diodes are fully qualified and released for production use.

China Mobile Research Institute and SkyCross demo tunable MIMO antenna for multimode, multiband handsets in LTE deployments
BEIJING, CHINA & VIERA, USA: China Mobile Research Institute and SkyCross announced a demonstration of a tunable, MIMO antenna design for multimode, multiband handsets in LTE deployments around the globe. The world’s first compact, tunable MIMO antenna covers 12 frequency bands ranging from 700 MHz to 2.7 GHz for TD LTE/LTE FDD/TD SCDMA/GSM EDGE/WCDMA deployments worldwide.
China Mobile believes that the convergence of TDD and FDD and the support of multiband are important for the mobile industry to realize the global scale and global roaming capabilities of the LTE standard. Cooperating with industry partners, China Mobile has made great strides in the convergence of TD-LTE and LTE FDD. The vision of "one standard, one network platform, and single-chipset solutions” has built a solid foundation for the development of a global LTE terminal.
In September 2010, China Mobile Research Institute and SkyCross signed a joint memorandum of understanding (MoU) to jointly pursue compact MIMO antenna design and implementation for multimode, multiband LTE handsets. China Mobile provided detailed requirements for global frequency band combinations needed including TD LTE/LTE FDD/TD SCDMA/GSM EDGE/WCDMA for potential global LTE and legacy network co-deployment, as well as target global roaming bands. China Mobile also provided detailed antenna performance requirements meeting 3GPP specifications.
SkyCross conducted all the antenna design and implementation using a software-configurable approach to tune the antenna frequency band coverage from 700 MHz to 2.7 GHz. The final tunable, multimode, multiband, MIMO antenna design was tested at the China Mobile Research Institute and TMC laboratories in Beijing and satisfies China Mobile’s performance requirements.
Compact, multiband MIMO antennas are a key element in executing multimode, multiband handset designs for global LTE deployments since LTE band definitions cover nearly all the possible unpaired TDD and paired FDD frequencies that all mobile operators use around the world. With multiband MIMO antennas now in place, the mobile handset ecosystem can now move forward in developing the remaining multiband components including power amplifiers, filters and duplexers, switches, RFICs, and front-end-modules.
“Our joint development effort with SkyCross has demonstrated that cost-effective, multimode, multiband antennas are technically achievable for global LTE handsets,” said Bill Huang, General Manager of China Mobile Research Institute. “We believe this demonstration will accelerate the development of universal handsets capable of roaming worldwide, as well as create the manufacturing volume to meet all operators’ requirements.”
“SkyCross is honored to collaborate with China Mobile on an initiative that is so important to the future of the wireless industry,” said Ben Naskar, SkyCross CEO and Chairman. “Multiband, state-tunable ST-iMAT MIMO antennas enable 4G wireless devices to support worldwide roaming without sacrificing performance or increasing antenna size.”
China Mobile is the largest mobile operator by number of subscribers in the world. SkyCross is a global developer and manufacturer of advanced antenna and RF solutions that are powering the emergence of 4G networks.
