Schottky Diodes Deliver Efficiency Boost For Solar Power Apps

Highly suitable for use in converters for solar power systems, the STPSC806D and STPSC1006D SiC Schottky diodes are also useful in power supplies for servers and telecom systems and motor controllers. The diodes employ SiC technology that allegedly enables engineers to consider a lower maximum current rating for the diode. For switched-mode power supply designers, they allow higher switching frequencies, allowing for smaller filtering capacitors and inductors. According to the company, SiC technology is able to deliver these benefits because no reverse recovery charge accumulates during the diode’s normal conduction period. Eliminating this reverse recovery charge, SiC Schottky diodes have much lower switching losses, leading to higher efficiency and lower heat dissipation. Prices for the 8A STPSC806D and 10A STPSC1006D are $3.90 and $4.90 each/10,000, respectively. STMICROELECTRONICS, Lexington, MA. (888) 787-3550.
