Two-chip SLIC Protector Modified TO-220 RoHS ¨ This two-chip SLIC modified TO-220 unidirectional protector is constructed with a 1 (T) 2 (G) 3 (R) SIDACtor® device and an integrated diode. It protects SLICs (Subscriber Line Interface Circuits) from damage during transient voltage activity and enables 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 6.40 through Figure 6.43 in Section 6, “Reference Designs” of this Telecom Design Guide.

For non-RoHS compliant device, delete “L” from part number. 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. • Parallel capacitive loads may affect electrical parameters. • Compliance with GR 1089 or UL 60950 power fault tests may require special design considerations.
