I was designing a snubber and thought about using a MOV to clamp the voltage spike below 250 so I can use the 250 volt capactors I have, but a 130 Volt (Littlefuse brand) MOV limits voltage to about 220 volts at 1 milliamp. Obviously, the current spike when a Triac shuts off is way more than 1 milliamp.
Perhaps I am out of date. Can anyone name a device that has lower clamping voltages per amp than a similar voltage rated MOV?
ps, I'm in USA with 125V mains and 60 Hz frequency.
