1 *RoHS COMPLIANT TISP4C0LN THRU TISP4C035LN LOW CAPACITANCE BIDIRECTIONAL THYRISTOR OEROLTAGE PROTECTOR This series is, is not recommended for new designs. The Model TISP4P0xxLN Series is the recommended pin-to-pin replacement. TISP4C0xxLN Overvoltage Protector Series Designed for ADSL, ADSL, DSL, DSL protection SOT3-5 Package (Top iew) Ion-Implanted Breakdown Region - Precise and Stable oltage (Tip) 5 (Tip) Low oltage Overshoot Under Surge Low Off-State Capacitance Device Name DRM (BO) TISP4C0LN 8 TISP4C00LN 0 TISP4C05LN 6 5 TISP4C035LN 4 35 Rated for International Surge Wave Shapes Wave Shape Standard A 8/0 IEC /000 GR-089-CORE 8 Description Device Symbol Terminal typical application names shown in parenthesis. NU - Non-usable; no external electrical connection should be made to this terminal. MD-SOT a This range of devices is designed to protect xdsl line-driver interfaces from overvoltages. Overvoltages are normally caused by a.c. power-system or lightning-fl ash disturbances which are induced or conducted onto the telephone line. These symmetrical SD-TISP4-00-a protectors are two-terminal thyristor-crowbar devices. They can be used to protect between conductors, or a pair of devices can be deployed to protect from line to ground. When placed between the xdsl line driver IC and the transformer, this protector will clamp and switch into a low-impedance state, safely diverting the energy transferred by the xdsl coupling transformer. The low capacitance design makes this device suitable for designs from ADSL all the way up to 30 MHz DSL. NU 3 4 Telecom ports need protection against Common Mode (Longitudinal) and Differential (Metallic) surges, to comply with international standards such as ITU-T K.0, K. or K.45, Telcordia GR-089-CORE and YD/T. Common Mode surges are resisted by the galvanic isolation of the coupling transformer which is commonly rated to k or greater. Differential surges can be transmitted by the transformer, and can stress the Line Driver Interface IC. As the xdsl interface circuit is designed to operate from 3 khz to to 30 MHz, nearby high frequency events - such as cable fl ashover or primary protection activation - can generate damaging conditions for the interface requiring this type of protection. Please contact your Bourns representative if the protection voltage you require is not listed.
