Overview
™ Battery Tracking TransClamp™ For SLIC Linecard Protection PROTECTION PRODUCTS Description 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 ( -VBAT ) 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 TRNWT-001089, FCC Part 68, ITU K17-K20, and IEC 61000-4-5.
The high surge capability is advantag...
