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 TISP61060 limits voltages that exceed the SLIC supply rail voltage. A SD6XAE Terminals K1, K2 and A correspond to the alternative line designators of T, R and G or A, B and C. The negative protection voltage is controlled by the voltage, VGG, applied to the G terminal. The SLIC line driver section is typically powered from 0 V (ground) and a negative voltage in the region of -10 V to -70 V. The protector gate is connected to this negative supply. This references the protection (clipping) voltage to the negative supply voltage. As the protection voltage will track the negative supply voltage, the overvoltage stress on the SLIC is minimised. (see Applications Information). 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 will crowbar into a low voltage on-state condition. As the current subsides the high holding current of the crowbar prevents d.c. latchup. PRODUCT INFORMATION Information is current as of publication date. Products conform to specifications in accordance with the terms of Power Innovations standard warranty. Production processing does not necessarily include testing of all parameters. 1 TISP61060D, TISP61060P DUAL FORWARD-CONDUCTING P-GATE THYRISTORS PROGRAMMABLE OVERVOLTAGE PROTECTORS SEPTEMBER 1995 - REVISED SEPTEMBER 1997 These monolithic protection devices are fabricated in ion-implanted planar vertical power structures for high reliability and in normal system operation they are virtually transparent. The buffered gate design reduces the loading on the SLIC supply during overvoltages caused by power cross and induction. absolute maximum ratings RATING Repetitive peak off-state voltage, IG = 0, -40°C ≤ TJ ≤ 85°C Repetitive peak gate-cathode voltage, VKA = 0, -40°C ≤ TJ ≤ 85°C Non-repetitive peak on-state pulse current (see Notes 1 and 2) 10/1000 µs 10/160 µs 2/10 µs Non-repetitive peak on-state current (see Notes 1 and 2) 60 Hz sine-wave, 25 ms 60 Hz sine-wave, 2 s Continuous on-state current (see Note 2) Continuous forward current (see Note 2) Operating free-air temperature range Storage temperature range Lead temperature 1,6 mm (1/16 inch) from case for 10 s ITM IFM TA Tstg TL ITSM 6 1 0.3 0.3 -40 to +85 -40 to +150 260 A A °C °C °C Arms ITSP 30 45 50 A SYMBOL VDRM VGKRM VALUE -100 -85 UNIT V V NOTES: 1. Initially the protector must be in thermal equilibrium with -40°C ≤ TJ ≤ 85°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). Above 85°C, derate linearly to zero at 150°C lead temperature. recommended operating conditions MIN CG Gate decoupling capacitor TYP 100 MAX UNIT nF electrical characteristics, -40°C ≤ TJ ≤ 85°C (unless otherwise noted) PARAMETER ID Off-state current VD = -85 V, VGK = 0 V TEST CONDITIONS TJ = 25°C TJ = 85°C MIN TYP M.
