1 / 8 page  PRELIMINARY 1 www.semtech.com PROTECTION PRODUCTS TC03A-200 Battery Tracking TransClamp™ ™ ™ ™ ™ For SLIC Linecard Protection PRELIMINARY Description Features Circuit Diagram Schematic & PIN Configuration Revision 9/2000 The battery tracking TransClamp series of transient voltage suppressors (TVS) are designed to protect subscriber line interface circuits (SLIC) from transient voltages resulting from lightning strikes and AC power line disturbances. The TC03A-200 integrates all the components necessary to protect SLIC ICs from line to ground for positive and negative transients. For negative transient events, the TVS thyristor will crowbar or “fire” when the line voltage exceeds the gate reference voltage. The gate voltage is referenced to the battery voltage ( -V BAT ) plus the VF of the series rectifier. The device firing voltage range is -5V to -100V. External diodes are used to shunt positive transients to ground. These devices are designed to meet industry standard transient immunity requirements such as Bellcore TR- NWT-001089, FCC Part 68, ITU K17-K20, and IEC 61000-4-5. The high surge capability is advantageous in harsh environments, and offers better reliability than "low surge" rated devices. The integrated design saves board space and increases equipment reliability by replacing multiple discrete components. The device may be used to protect any SLIC and is particularly suited for those with integrated ring generators. Applications Mechanical Characteristics !
