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 circuit (SLIC) from transient voltages resulting from lightning strikes and AC power line disturbances.
The TC04A-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.
For positive transients, the surge-rated rectifiers will be forward biased, shunting the current to ground.
An external capacitor is used to aid in gate triggering during fast rise time transients.
The device may be used to protect any SLIC including those with inte...
