1N4454 Diode Temperature-Current Derating Curve [DO-213AA]
High Conductance Ultra Fast Diode.

1N4454 Diode Current Derating Curve, PCB Temperature
Thermal Characteristics:
Derate the 1N4454 above 250C by 3.33mW/0C.
Use the 1N4454 diode graph to determine maximum operation current based on the operational temperature of the Printed Circuit Board [PCB]. Diode Derating Curves.
Temperature-Current derating is a standard design practice for electrical engineers, use the two gray curves for proper derating of the 1N4454 diode.
To obtain a higher operational operating temperature apply forced air cooling, the graph relates to still air.
