... Description The TISP61089HDM is a dual forward-conducting buffered p-gate thyristor (SCR) overvoltage protector designed to protect monolithic SLICs (Subscriber Line Interface Circuits) against overvoltages on the telephone line caused by lightning, a.c. power contact and induction. The TISP61089HDM limits voltages that exceed the SLIC supply rail voltage. The TISP61089HDM parameters are specified to allow equipment compliance with Telcordia GR-1089-CORE, Issue 3 and ITU-T recommendations K ...

... Positive overvoltages are clipped to ground by diode forward conduction. Negative overvoltages are initially clipped close to the SLIC negative supply rail value. If sufficient current is available from the overvoltage, then the protector SCR will switch into a low voltage on-state condition. As the overvoltage subsides the high holding current of TISP61089HDM SCR prevents d.c. latchup. The TISP61089HDM is designed to be used with a pair of Bourns requires the series overcurrent element to become open-circuit or high impedance ...

... F1b B1250T Figure 3 illustrates how a typical SLIC protection circuit may look for a TISP61089HDM and a pair of Bourns protectors. This is a generic circuit that is designed to withstand both lightning surge testing and AC power fault testing. As applications can differ recommended you contact your Bourns representative for detailed applications guidance on your specific design. ...

... The system should not burn, fragment, or become an electrical safety hazard. The test data in Figure 5 illustrates that the TISP61089HDM and the B1250T are current coordinated, as the fuse interrupt time is shorter than the time it takes to damage the TISP61089HDM package for a given current. ...
