IR Intros 87CNQ020 and 47CTQ020 Schottky Diodes

International Rectifier (El Segundo, CA) has introduced a new 20V Schottky diode family designed to help power supply design engineers overcome the efficiency limitation in the output rectification process of switchmode power supplies by offering the lowest Vf in the industry (0.30V). The new 87CNQ020 and 47CTQ020 allow designers to achieve significantly improved system efficiency, increased power density and improved reliability in the 3.3V switch model supplies that are increasingly popular in telecom applications. The new 20V Schottky diodes are offered in various packages to enhance power density with maximum efficiency, utilizing a special die aspect ratio to take full advantage of the package die bond area. The diodes combine a new proprietary barrier metal with optimized epitaxial silicon and new planar geometries. This provides low Vf, which is needed for high efficiency Schottky diode rectification, and an operation junction temperature range required to guarantee reliability in telecom and industrial applications. Pricing is $1.20 for the 47CTQ020 and $6.00 for the 87CNQ020 in 10k lots.
