International Rectifier Corp. (IR, El Segundo, CA) introduced a new series of 320A and 400A standard-recovery, stud-mount rectifiers in the DO-9 package. The new devices expand IR's current line of DO-9 rectifiers with ratings from 50V to 3,200V and 300A to 400A. The devices are made for high-voltage, high-current industrial applications such as welding, battery chargers, power supplies and light-duty traction applications.
The 240U060D, 240U080D, 240U100D and 240U120D (320A) and the 400U080D, 400U120D, 400U160D (400A) rectifiers are manufactured with a new process that combines brazed-die construction with compressed assembly. The new devices feature power-cycling performance and the ability to maintain stable forward-voltage characteristics.
Francesco Vallone, IR product marketing manager, said, "Stud-mount rectifiers are the 'workhorse' of the power electronics industry. IR's new rectifiers are made with the latest techniques to enhance performance while remaining cost-effective."
The new 320A and 400A stud-mount rectifiers are now available. Pricing is $12.80 each for the 320A versions and $16.20 each for the 400A devices in 100-unit quantities.
