The question is self explanatory. I cannot find a TVS diode with a suitable voltage rating for my application. So, can I use a 'typical' fast diode to clamp high reverse voltages by breaking down? Or will repeated reverse breakdown hurt the diode?
Sorry for being inactive for a while. My application is to protect the IGBTs in a half bridge inverter for a tesla coil that I'm making from di/dt induced voltage spikes. The switching frequency will be quite high, somewhere around 250 Khz running from rectified 220VAC. I obviously don't need a precision reverse breakdown voltage for that, just somewhere below the 600V collector-emitter voltage rating of the transistor.So what is your "application" and what is the source of the voltage you want to clamp?
Why not use the ones shown in the schematic you posted? https://www.i-components.si/components/Hamlin-Littelfuse/1.5KE510A.htmlI cannot find a TVS diode with a suitable voltage rating for my application.
I can't find them. I wouldn't have posted this question if I could,Why not use the ones shown in the schematic you posted? https://www.i-components.si/components/Hamlin-Littelfuse/1.5KE510A.html
I found them for you. Or you could take the values from the data sheet of that link and look for another brand. Part of doing this electronics hobby is learning to find the parts, or the hunt for the parts.I can't find them. I wouldn't have posted this question if I could,
So it takes time to get the parts, I can't imagine how the need for a Tesla coil is life threatening.The only problem is... it will take at least a month to arrive.
