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 rectifi-
ers 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 integrated ring generators.
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 integrated design saves board space
and increases equipment reliability by replacing mul-
tiple discrete components.
