To help designers meet ground lead creepage, requirements being introduced by international safety standards such as IEC 60950 and UL1950, Power Innovations has introduced three enhanced versions of its proven TISP family of programmable dual Subscriber line interface circuit (SLIC) protectors.
The devices provide 3 mm creepage clearances to ground despite using an industry standards small outline footprint, by reassigning pins and upgrading the current carrying capability within the package. The TISP61089S, TISP61089AS and TISPPBL2S are dual programmable protectors, offering respectively 85 and 110 V operating voltages, and optimised protection for Ericsson PBL SLICs. All models provide the same broad range of international surge ratings as the original versions, including GR 1089 Core, and ITU-T K20/K21.
In addition to providing designers with a route to compliance with new safety standards, full application data is available which gives guidance on compliance with first and second level GR 1089 Core surge and power fault requirements, including comprehensive current/time coordination graphs.
These TISP protectors integrate two buffered and voltage-triggered thyristors, each with an inverse-parallel power diode protection of both Tip and Ring lines to ground. Positive voltages are clamped to ground by the diodes, while negative voltages are initially clipped to the supply rail, followed by a low voltage crowbar for higher current surges. The high holding current of 150 mA ensures that the protector switches off again once the surge has been cleared.
