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 鈥渇ire鈥?when the line voltage exceeds the
gate reference voltage. The gate voltage is referenced
to the battery voltage ( -V
BAT
) plus the V
F
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.
