SMT Devices Protect Network & Customer Premises Equipment

When used together, the PolySwitch TS600 resettable fuses and 100A-rated SiBar thyristor surge protectors provide a complete, surface-mount solution for the overcurrent and overvoltage protection of telecomm equipment while meeting demanding Bellcore GR-1089 and UL1950 3rd edition requirements. PolySwitch TS600 devices automatically reset after an overcurrent event, eliminating the need for telecomm operators to search out and replace the blown component. Other features include a hold current of 170-200 mA, typical resistance of 10 ohms, and a normal operating voltage rating of 60V.The SiBar thyristor surge protectors switch into low impedance state when the breakover voltage is exceeded, allowing the device to conduct surge current away from the sensitive telecomm electronics.
