    Hi Guys,

    I am looking for an equivalent replacement for the following

    1 x OA47 diode
    1 x 3V0 zener diode (type BZY88)

    I couldnt find exact ones, so can any one suggest something equivalent and one I can find easily.

    Thanks.

    The BZY 88 series of zeners were 400 milliwatt, 250 milliamp diodes.

    The 1S 2000 series is a similar 400mW device

    1S2030 is 10%; 1S2030A is 5% tolerance.

    Alternatively try

    1S7030 or 1S7030A.

    Other similar European number types are

    BZV55
    BZV60
    BZX55
    BZX79
    BZX83
    ZPD

    all are 500mW types

    The 0A478 was a germanium gold bonded switching diode, 25 volts PIV and 110 mA current.

    If the germanium (low) forward voltage is important to your application try

    1N98A
    1N273
    1N279
    AAY series

    AA series eg AA143, AA144
