IR Presents New ETX and ETL Series Diodes

International Rectifier Corp. (IR, El Segundo, CA) introduced its new ETX and ETL Series of high-efficiency diodes for active power-factor correction (PFC) in switch-mode power supply applications. Power-factor correction circuits smooth out the pulsating ac mains current, allowing the maximum amount of power to be drawn from ac lines, and are used in a wide range of ac-operated electronic products - from large computer system servers and telecom systems to small notebook computer power adaptors, video games and other home entertainment devices.

The new PFC-specific diodes enable lower system losses (less heat), and lower stress in switching components in power supplies, shrinking circuits and creating higher current density for space-restricted, high-performance applications. The ETX Series diodes have low reverse-recovery charge for continuous current-mode PFC, while the ETL Series diodes have low forward-voltage drop for discontinuous current-mode PFC applications.

The new PFC diodes are now available. Pricing begins at $0.34 each in 10,000-unit quantities for the 8ETL06.
