Twin SLIC Protector
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/µs.
• 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.
