Use the links to determine how much to derate the current parameter for the diodes listed.
Temperature derating is a standard design practice for electrical engineers, and should be followed to insure that the junction temperature of the diode is not exceeded.
The curves provide increasing temperature vs decreasing device current.
A general rule-of-thumb for diode current derating, also called Stress Ratio or Derating Factor.
Power Diode Stress Ratio = Operating IF / Rated If = 70%
Small Signal Stress Ratio = Operating IF / Rated If = 85%
