    i have searched before minutes and there is no such diode in my country. If you tell me replacement maybe i can have it from Bulgaria.From foreign i see there is no such at aliexpress (and alibaba) and at ebay. I have to compare the newark farnell and other stores prices for shipping.

    You can first find the group of similar diodes with the same or greater ratings for current and voltage. Then find which ones are available in your country. Then, you might want to ask help deciding from that group of devices.

    Hello,

    The diode is an 600 V, 5 A H-Series PFC Diode.
    The measurement does not show the defect.
    The forward voltage at 5 A is 2.6 to 3.1 Volts.
    Your meter will likely use a couple of miliamps.
