Processing High Voltage SMD Diodes...Is it Possible?
SMF and SXF high voltage diodes are constructed using a hermetically-sealed diode over-molded with a rigid epoxy.   The advantages of using a diode such as this is that they are easy to pick-and-place, and are cost effective.  They pack a lot of high voltag...

Current Ratings in High Voltage Diodes, and the SXF6525 in Particular
The current ratings of a diode
(including surge currents) are best though of as guidelines.  The thing that keeps a diode from successfully operating at higher currents in excess of the published rating is the generated heat, and the inability to remove the...
