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: All measurements are made at an ambient temperature of 25 °C. IPP applies to -40 °C through +85 °C temperature range. IPP is a repetitive surge rating and is guaranteed for the life of the product. VDRM is measured at IDRM. VS and VF are measured at 100 V/s. Special voltage (VS and VDRM) and holding current (IH) requirements are available upon request. Off-state capacitance (CO) is measured across pins 1-2 or 3-2 at 1 MHz with a 2 V bias. Capacitance across pins 1-3 is 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.
