Selection Guide
and Product Data
This section has two parts:
• A Selection Guide that walks you through the process of
selecting the correct RGE device for a circuit.
• Product Data that outlines electrical characteristics,
physical characteristics, agency recognitions, environmental
specifications, component layouts, tape and reel specifications,
and ordering information for RGE devices.
RGE Selection Guide
Follow these seven steps to select a PolySwitch RGE device for
a circuit:
1. Define the operating parameters for the circuit.
These include:
• Maximum ambient operating temperature
• Normal operating current
• Maximum operating voltage (RGE is 16 V maximum)
• Maximum interrupt current
2. Select the RGE device that accommodates the circuit’s maximum
ambient operating temperature and normal operating current.
3. Compare the RGE device’s maximum operating voltage and maxi-
mum interrupt current with the circuit’s to be sure the circuit does
not exceed the device ratings.
4. Check the RGE device’s time-to-trip be to sure it will protect the
circuit.
5. Verify that the circuit’s ambient operating temperatures are within
the RGE device’s operating temperature range.
6. Verify that the RGE device’s dimensions fit the application’s space
considerations.
7. Independently evaluate and test the suitability and performance
of the RGE device in the application.

Define the circuit’s operating parameters.
Fill in the following information about the circuit:
Maximum ambient operating temperature
Normal operating current
Maximum operating voltage (RGE is 16 V max.)

2.
Select the PolySwitch RGE device that will accommodate the
circuit’s maximum ambient operating temperature and
normal operating current.
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 RGE device that will best accommo-
date the circuit.

representation of the data in the table below.

Compare maximum operating voltages and maximum
interrupt currents.
Look down the first column of the table below to find the part number
you selected in Step 1. Look to the right in that row to find the device’s
maximum operating voltage (V max.) and maximum interrupt current
(I max.).
Compare both ratings with the circuit’s to be sure the circuit’s ratings
do not exceed those of the RGE device.

Determine time-to-trip.
Time-to-trip is the amount of time it takes for a device to switch to a
high-resistance state once a fault current has been applied across the
device.
Identifying the RGE device’s time-to-trip is important in order to provide
the desired protection capabilities. If the device you choose trips
too fast, undesired or nuisance tripping will occur. If the device trips
too slowly, the components being protected may be damaged before
the device switches to a high-resistance state.
The chart below shows the typical time-to-trip at 25°C for each
PolySwitch RGE device. For example, the chart indicates that the typi-
cal time-to-trip for RGE500 at 10 A is 10 seconds.
On the chart below, find the typical time-to-trip for the RGE device you
selected. If the RGE device’s time-to-trip is too fast or too slow for the
circuit, go back to Step 2 and choose an alternate device.

Verify ambient operating conditions.
Ensure that your application’s minimum and maximum ambient
temperatures are within the operating temperature range of –40°C
and 85°C.
Maximum device surface temperature in the tripped state is 125°C.
