Cree Unveils New Surface Mount Schottky Diode

Cree, Inc. stated that it is now shipping the industry's first commercial 1200V surface mount silicon carbide (SiC) Schottky diode.

Packaged in an industry-standard surface mount TO-252 D-Pak, the Schottky diodes deliver the same performance as Cree's TO-220 through-hole devices, but with a smaller board footprint and lower profile. This enables the design of smaller, lower cost, and more efficient solar power micro-inverters, compared to systems designed with larger and bulkier through-hole parts, according to Cree.

Cengiz Balkas, Cree Vice President and General Manager, Power and RF, said Cree developed the part because customers designing high-efficiency micro-inverters for solar power applications wanted to simplify their designs without compromising system efficiency.

Balkas went on to say that those customers were looking for a surface mount device that could deliver the same performance of SiC Schottky diodes including zero reverse recovery losses, high frequency operation with a low EMI signature, and reduced operating temperatures.

The move to the surface mount D-Pak was a "natural extension of our Schottky diode product line to serve this critical market," said Balkas.

Alessandro Di Nicco, design engineer of New Platforms for Power-One, said design trends in solar power micro-inverters are requiring the use of surface mount components with smaller footprints and lower profiles.

Di Nicco said the new Schottky diode "enables us to both reduce the size of the inverter circuitry and lower the cost, while maintaining reliability and high efficiency."

Cree C2D05120E Schottky diodes are rated for 5A and 1200V, with approximate board mounted dimensions of 6.6mm wide x 9.9mm long x 2.3mm high. Operating junction and storage temperature is rated for -55°C to +175°C.
