... For the most basic design, all that is needed is a circuit protector, two resistors and a capacitor. 2.2 Surge Protection Although the CPC1465 is current limited not an over-voltage surge protector. To protect the CPC1465 against destructive over-voltage transients, Clare recommends the use of a crowbar-type surge protector that limits the surge voltage seen by the CPC1465 to 250 V ...

... PR+ and PR- pins. 2.6.2 Over-Voltage Conditions Potentials in excess of 100 V applied to the tip and ring interface will cause the CPC1465 to disable the sealing current hold circuit and enter a standby state with very little current draw. Once the over-voltage condition is removed, the CPC1465 automatically resumes normal operation ...
