Twin SLIC Protector Modified TO-220 Twin SLIC Protector Modified TO-220 1 (T) 2 (G) 3 (R) 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.

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.
