1.
Fill in the following information about the circuit:
Maximum ambient operating temperature
Normal operating current
Maximum operating voltage (RUE is 30 V max.)
Maximum interrupt current
2.
Look across the top of the table below to find the temperature that
most closely matches the circuit’s maximum ambient operating temper-
ature. Look down that column to find the value equal to or greater than
the circuit’s normal operating current. Now look to the far left of that
row to find the part number for the RUE device that will best accommo-
date the circuit.
The thermal derating curve located on the next page is a normalized
representation of the data in the table below.
