International Rectifier Introduces New 300V Family of Diodes

International Rectifer (El Segundo, CA) announced the introduction of their new 300V ultrafast diodes to its fast-recover epitaxial diode (FRED) family. The new 300V family includes 8A (8ETH03), 15A (15ETH03) and 30A (30EPH03, 30CPH03) devices optimized for 48V switch-mode power supply systems for telecom and datacom applications.

According to the company, the new 300V ultrafast diodes feature 50 percent lower reverse-recovery current compared to the best competitive device. In addition, the new devices have smaller forward-conduction losses and lower reverse-recovery time compared to 400V devices. The improvements result in three percent lower losses than the industry-best 300V device, and up to an 18-percent reduction in power losses when compared in-circuit to the industry-best 400V ultrafast diode, according to IR.

Stephen Oliver, International Rectifier marketing manager for the ac-dc sector, stated, "IR's new 300V ultrafast diodes can replace 400V or 200V devices for increased converter efficiency. More efficiency can reduce heatsink size, or increase power density within the same footprint in a circuit upgrade. More efficiency also translates into lower temperature and increased reliability."

The new 300V ultrafast diodes are available immediately. Pricing ranges from $0.56 to $1.35 each in 10,000-unit quantities.
