Description
The TISP61089HDM is a dual forward-conducting buffered p-gate thyristor (SCR) overvoltage protector. It is 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.20, K.21 and K.45. The SLIC line driver section is typically powered from 0 V (ground) and a negative voltage in the region of -20 V to -155 V. The protector gate is connected to this negative supply. This references the protection (clipping) voltage to the negative supply voltage. The protection voltage will then track the negative supply voltage and the overvoltage stress on the SLIC is minimized.

TISP61089HDM Overvoltage Protector
Description (Continued)
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(R) B1250T fuses for overcurrent protection. Level 2 power fault compliance requires the series overcurrent element to become open-circuit or high impedance. For equipment compliant to ITU-T recommendations K.20, K.21 or K.45 only, the series resistor value is set by the coordination requirements. For coordination with a 400 V limit GDT, a minimum series resistor value of 6.5 is recommended.

NOTES: 1. Initially the device must be in thermal equilibrium with TJ = 25 C. The surge may be repeated after the device returns to its initial conditions. 2. The rated current values may be applied either to the Ring to Ground or to the Tip to Ground terminal pairs. Additionally, both terminal pairs may have their rated current values applied simultaneously (in this case the Ground terminal current will be twice the rated current value of an individual terminal pair). Ratings are obtained by using the gate circuitry as shown in Fig. 3. 3. Rated currents only apply if pins 1 & 8 (T ip) are connected together, pins 4 & 5 (Ring) are connected together and pins 6 & 7 (Anode) are connected together. 4.

GR-1089-CORE Issue A.C. Power Fault testing has been comprehended in the design of the TISP61089HDM. For compliance, circuit designs must pass both First Level and Second Level A.C. Power Fault testing. First Level Power Fault testing requires that the equipment shall not be damaged and continues to operate correctly without disruption to other parts of the system. In laboratory tests it has been shown that the circuit shown in Figure 3 can pass these tests without damage. Figure 4 shows the TISP61089HDM I TSM rating to be above the level of GR-1089-CORE First Level tests. Second Level Power Fault testing may result in the equipment becoming non-operational, but any component failure should not allow the equipment to become a hazard. 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.
