Arc-Welding Diodes Feature Fast Recovery Times

Developed to increase power and improve reliability and efficiency in high-frequency inverter welder output stages, the 60EPU02, 80EBU02, 150EBU02, 80EBU04 and 150EBU04 arc-welding diodes feature t_rr times from 35 to 60 ns. Four of the devices are available in the company's POWIRTAB package and are rated at 80A. The 60EPU02 is available in a TO-247 package and is rated at 60A. Internally, the devices feature a large anode tab, which is said to allow more wire bonds to be placed on the silicon die chip. This is said to improve forward-voltage drop and increase surge-handling capability to as high as 1,600A. Pricing begins at $1.30 each/10,000.
