Selection Guide for SiBar Thyristor Surge Protectors

Fill in the following information about the circuit:

Maximum ambient operating temperature ______________________

Maximum DC supply voltage (V

Maximum ringing (AC) voltage (V

______________________

System voltage damage threshold

__________________________

Maximum fault current and duration

__________________________

Maximum system operating current

Maximum operating voltage = V

Refer to Table V1 to select a SiBar thyristor device with a maximum off-

state voltage (V

mum operating voltage of your system.

greater than the rated maximum breakover voltage (V

Refer to Table V1 to confirm that the maximum breakover voltage of the

device you selected in Step 2 is less than the system voltage damage

threshold.
