    what kind of failure will happen to the diode if the forward current is more than the diode's rated forward current and also what will happen if the reverse voltage of the diode is more than the diode's rated reverse voltage?

    Generally, the diode will fail and be destroyed.

    Whether it will get short or opened?

    Both, typically semiconductors fail shorted first and then often burn open circuit (but not always) due to the high current.

    When the diode fails, it become open circuit or short circuit.
    Now I have a question, why the diode get short or open circuit when it fails.
    Is there any kind of diode that the probability of becoming open circuit be more than the probability of becoming short circuit?
    Is there this kind of diode?
