Use a 1n5401 large area silicon not specked like this but it should work. I
used 4001's for about 30pf varicap as FM modulators for pirate radio about
20 years ago they work fine. Effectively the bigger the diode the larger the
silicon hence capacitance any 'big' rectifier will do

Subject: [EE] varactor diode 200pF

I'm searching for a 200pF-300pF varactor diode with large capacitor
variation, at least 10 (something equivalent with MV1405). No luck at
Digikey or Mouser.
Any clue ? The RF guys are allive ?
