Fixed Voltage SLIC Protector

integrated diode. They protect SLICs (Subscriber Line Interface Circuits) from damage

during transient voltage activity and enable line cards to comply with various regulatory

requirements including GR 1089, ITU K.20, K.21 and K.45, IEC 60950, UL 60950, and

TIA-968-A (formerly known as FCC Part 68).

For details of specific design criteria, see Figure 6.31 in Section 6, “Reference Designs” of

this Telecom Design Guide).

* “L” in part number indicates RoHS compliance. For non-RoHS compliant device, delete “L” from part number.

For individual “SA” and “SC” surge ratings, see table below.

General Notes:

• Parallel capacitive loads may affect electrical parameters.

* Current waveform in µs
