    I'm currently designing a buck converter with a MBRA340 diode and the
    only problem is that it
    has high junction capacitance at 0V (900pF). The junction capacitance
    drops significantly pass 5V (<500pF). I wanted your opinion on how
    this would effect a buck converter, as the TRR on the diode is still
    very fast. I believe this will be a non-issue, as it is a variable
    capacitance (depending on Vb), along with the fact that most of the
    capacitance will
    be spent with Vb greater than 5V. Your feedback on this is greatly
    appreciated. Thanks.

    Sounds like that diode may be good for FM work...
