Maybe I'm confusing this with something else but I always thought 1N4007's
were 1000 V PIV, 1 A rectifiers.

I believe "any" diode has varactor characteristics to some extent but if you
need a varactor you'd be better off using one designed as a varactor.

The common 1N4007 seem to work for HF but what is the max. frequency they
can be used as varactors?

And how about zener diodes?
