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.

Features
◆ Transient protection for telecommunications lines to Bellcore 1089 (long haul), VDE 0433, ITU K20 IEC 61000-4-5 (Lightning), and FCC Part 68
◆ High surge current rating (100A, tp = 10/1000µs)
◆ Protects up to two Tip & Ring line pairs
◆ Gate firing voltage is referenced to the system battery voltage
◆ Wide firing voltage range: -5V to -100V
◆ High holding current: 200mA
◆ Replaces discrete components
◆ Solid-state TVS process technology

Applications
◆ Subscriber Line Interface Circuit (SLIC) Protection
◆ Central Office Equipment
◆ ISDN Terminal Adaptors
◆ Cable Telephony
◆ Small Office Home Office (SOHO) Applications
◆ Wireless Local Loop (WLL)
