Twin SLIC Protector Modified TO-220

Subscriber Line Interface Circuits (SLIC) are highly susceptible to transient voltages, such

as lightning and power cross conditions. To minimize this threat, Littelfuse provides this

dual-chip, fixed-voltage SLIC protector device.

For specific design criteria, see details in Figure 3.29.

* For surge ratings, see table below.

General Notes:

approximately half.

• Parallel capacitive loads may affect electrical parameters.

• Compliance with GR 1089 or UL 60950 power cross tests may require special design considerations. Contact the factory for further

information.
