Step 4.
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 PolySwitch 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.
Figures S11-S19 show the typical time-to-trip at 20°C for each of the
PolySwitch devices.
If the PolySwitch device’s time-to-trip is too fast or too slow for the
circuit, go back to Step 2 and choose an alternate device.
Step 5.
Ensure that your application’s minimum and maximum ambient
temperatures are within the operating temperature of -40°C to 85°C
(-40°C to 125°C for SMDH160).
Step 6.
Using dimensions in Table S4, compare the dimensions of the
PolySwitch device you selected with the application’s space con-
siderations.
Determine time-to-trip.
Verify ambient operating conditions.
Verify the PolySwitch device dimensions.
