EL SEGUNDO, Calif. — International Rectifier, IR(®) (NYSE: IRF) introduced today four new 60A Schottky diodes in the TO-220 package. The new CTQ series devices carry 50% to 200% more current than the industry-best parts in the same package.

The new 60A Schottky diodes can replace devices in larger packages such as the TO-247 or D-61 or reduce the number of paralleled TO-220 devices to achieve the 60A rating. When compared to industry-standard TO-247 60A Schottky diodes, the new IR devices save 75% in space and increase current density by a factor of four with a lower forward voltage for better efficiency. Alternatively, designers can replace an industry-standard Schottky diode packaged in a TO-220 rated at 40A, the maximum current rating from other manufacturers, with the new IR Schottky diodes to improve system efficiency up to 3.3%.

IR's new devices save space in high-performance power supply output rectification stages and Oring applications for 3.3V to 15V systems found in telecom equipment, or space-constrained applications such as notebook power adaptors.

Stephen Oliver, Marketing Manager for AC-DC Products at International Rectifier said, "The new Schottky diodes increase density in power supply output stages and allow the adaptors for next generation notebooks to keep the same form factor as notebook power requirements are increasing. Their characteristics also make them ideal for Oring applications in redundant power systems used for minimum down-time in telecom equipment."
