International Rectifier Corp. (IR, El Segundo, CA) introduced its new family of 15V, 30V, 45V and 100V high-current schottky diodes rated at 110A in surface-mount and through-hole D-61 packages. The new CNQ Series devices offer over 35 percent higher current-carrying capability than IR's previous-generation devices in the same package, and over a 100 percent increase in current density over competing devices in SOT-227- or TO-247-type packages.
The new diodes are suitable for high-power switch-mode power supplies (SMPS) for telecom/datacom systems; servers; workstations; mainframes; output rectification in SMPS systems; and OR-ing, (15V diodes for 5V, 3.3V and 1.8V output converters and 100V devices for 48V output converters) in N+1 redundant power supply systems. The diodes come in an improved D-61 package with a thicker baseplate and heavy-duty leads for increased current-handling capability. Improved bonding techniques have lowered the forward-voltage drop by up to 20 percent, compared to IR's previous-generation devices, reducing conduction losses while improving thermal performance.
The new diodes will be available in April 2002. Pricing begins at $6.90 each in 10,000-piece quantities for the 115CNQ015A.
