International Rectifier Announces the Development of Five New Recovery Diodes

October 08, 2000 by Jeff Shepard

International Rectifier (IR, El Segundo, CA) announced five new recovery diodes specifically developed to increase power and improve reliability and efficiency in high-frequency inverter welder-output stages.

Four of the new welding diodes, the 80EBU02, 150EBU02, 80EBU04 and 150EBU04, are available in IR's powIRtab package and are rated at 80A. The fifth device, 60EPU02, is rated at 60A and is packaged in the industry-standard TO-24 package for mounting flexibility in existing designs. The large anode tab of all these models allows more wire bonds to the silicon die chip in an effort to improve the forward voltage drop and increase the surge-handling capability to as high as 1,600A.

Francesco Valone, International Rectifier's high-power product marketing manager, stated, "IR's welding-specific diodes have at least three-percent-lower forward-voltage drop among devices of comparable recovery speed available on the market. This means the device is more efficient and requires less heatsinking, which reduces the cost, size and weight of the overall system."

Pricing for the new welding diodes begins at $1.30 each in quantities of 10,000.
