Selection Guide
Follow these steps to select the proper Thyristor surge protector for your application:
1. Dene 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
2. Select device with an off-state voltage rating (VDRM) above the maximum operating voltage at the minimum
operating temperature.
3. Select surge current ratings (IPPS and ITSM) > those which the application must withstand
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 t the application’s space considerations.
8. Independently evaluate and test the suitability and performance of the device in the application.

Notes:
The junction to lead thermal resistance represents a minimum limiting value with both leads soldered to a large near-innite 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.

Notes (1,2,4,5,6)
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 specications cannot be exactly met.
The current wave is more important than the voltage wave for accurate surge evaluation.
6. The waveform is dened 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 - T0
