PolySwitch Radial-leaded Resettable Devices
Step 1.
Fill in the following information about the circuit:
Maximum ambient operating temperature
Normal operating current
Maximum operating voltage
(i.e., RUE135 is 30V max.)
Maximum interrupt current
Step 2.
circuit’s maximum ambient temperature and normal operating
current.
Look across the top of Table R2 to find the temperature that most
closely matches the circuit’s maximum operating temperature. 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 PolySwitch device that will best accommodate the
circuit. Devices in this section are grouped by voltage rating; therefore,
your operating current requirement may be found in more than one
product grouping.
The thermal derating curves located in Figures R1–R5 are the normal-
ized representations of the data in Table R2.

rupt currents of the circuit.
Look down the first column of Table R3 to find the part number you
selected in Step 2. Look to the right in that row to find the device’s
