SELECTION GUIDE
Follow these steps to select the proper Thyristor surge protector for your application:
1. Define the operating parameters for the circuit:
• Ambient operating temperature range
• Maximum telephone line operating current (highest battery and shortest copper loop)
• Maximum operating voltage: (Maximum DC bias + peak ringing voltage)
• Maximum surge current
• System voltage damage threshold
• Select device with an off-state voltage rating (V
3. Select surge current ratings (I
4. Verify that the minimum holding current of the device at the maximum ambient temperature is above the maximum dc current of the
system.
5. Verify that the maximum breakover voltage of the device is below the system damage threshold.
6. Verify that the circuit's ambient operating temperatures are within the device's operating temperature range.
7. Verify that the device's dimensions fit the application's space considerations.
8. Independently evaluate and test the suitability and performance of the device in the application

Notes:
1. Thermal accumulation between successive surge tests is
not allowed.
2. The device under test initially must be in thermal
equilibrium with TJ = 25 °C.
3. Test at 1 cycle, 60 Hz.
4. Surge ratings are non-repetitive because instantaneous
junction temperatures may exceed the maximum rated TJ.
Nevertheless, devices will survive many surge applications
without degradation. Surge capability will not degrade over
a device's typical operating life.
5. Adjust the surge generator for optimum current-wave
accuracy when both voltage and current wave
specifications cannot be exactly met. The current wave is
more important than the voltage wave for accurate surge
evaluation.
6. The waveform is defined as A/B ms where:
A: (Virtual front time) = 1.25 X Rise time = 1.25 X (Tb - Ta)
B (Duration time to 50% level of Ipps) = T1 - T

Notes:
The junction to lead thermal resistance represents a minimum limiting value with both leads soldered to a large near-infinite heatsink. The
junction to ambient thermal resistance depends strongly on board mounting conditions and typically is 3 to 6 times higher than the junction
to lead resistance. The data shown is to be used as guideline values for preliminary engineering.
