The 1250 V direct surge voltage capability of the TS110-8 enables high robustness of the whole circuit breaker. The low leakage current of the TS110-8 reduces power consumption over the entire lifetime of the circuit breaker. The high off-state immunity (200 V/µs) insures the non tripping of the breaker in case of electrical fast transient (EFT) on the mains. The TS110-8 is available in through-hole TO-92 package with GAK and KGA pinout and in SMBflat-3L package. ## **Features** - On-state rms current, 1.25 A - Repetitive peak off-state voltage, 800 V - Non-repetitive direct surge peak off-state voltage, 1250 V - Non-repetitive reverse surge peak off-state voltage, 900 V **Table 1.

Non repetitive surge peak on-state current** DocID026589 Rev 1 5/10 **AC line transient voltage ruggedness** **TS110-8** ## **2 AC line transient voltage ruggedness** In comparison with standard SCRs, the TS110-8 is self-protected against over-voltage. The TS110-8 switch can safely withstand AC line direct surge voltages by switching to the on state (for less than 10 ms on 50 Hz mains) to dissipate energy shocks through the load. The load limits the current through the TS110-8. The self-protection against over-voltage is based on an overvoltage crowbar technology. This safety feature works even with high turn-on current ramp up. _Figure 16_ represents the TS110-8 in a test environment. It is used to stress the TS110-8 switch according to the IEC 61000-4-5 standard conditions. The TS110-8 folds back safely to the on state as shown in _Figure 17_ . The TS110-8 recovers its blocking voltage capability after the direct surge and the next zero current crossing. Such a non repetitive test can be done at least 10 times. **Figure 16. Overvoltage ruggedness test circuit for IEC 61000-4-5 standards** **Figure 17.
