“I have back-to-back Zeners from the final FET Gates to Ground on my DE. (No series resistors) Before installing them I tested how well they would clamp at RF frequencies, due to concerns I had about their speed. My tests using a scope and RF at 30 MHz showed that the 5 Watt Zeners I selected did in fact clamp at their design voltage. “
Can you give a little schematic or paragraph explaining how you did this test?
That would allow others to try to repeat the experiment.
