1 / 14 page TISP61060D, TISP61060P DUAL FORWARD-CONDUCTING P-GATE THYRISTORS PROGRAMMABLE OVERVOLTAGE PROTECTORS PRODUCT INFORMATION 1 SEPTEMBER 1995 - REVISED SEPTEMBER 1997 Copyright © 1997, Power Innovations Limited, UK 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. PROGRAMMABLE SLIC OVERVOLTAGE PROTECTION q Dual Voltage-Programmable Protectors - Third Generation Design using Vertical Power Technology - Wide -5 V to -85 V Programming Range - High 150 mA min. Holding Current q Reduced VBAT Supply Current - Triggering Current is Typically 50x Lower - Negative Value Power Induction Current Removes Need for Extra Protection Diode q Rated for LSSGR & FCC Surges q Surface Mount and Through-Hole Options - TISP61060P for Plastic DIP - TISP61060D for Small-Outline - TISP61060DR for Taped and Reeled Small-Outline q Functional Replacements for description The TISP61060 is a dual forward-conducting buffered p-gate 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 TISP61060 limits voltages that exceed the SLIC supply rail voltage.

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. device symbol 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, V GG, applied to the G terminal.
