Microwave oven diodes are rated for a couple thousand volts at high current so high voltage would likely cause early failure.
There should be plenty of focus diodes around. I suggest a direct replacement.

They used to have those plug in jobs, to replace a 1V2 or 2AV2. Try to get one of those and solder the leads to the pins.
