Balanced Three-chip SIDACtor® Device

This six-pin SMT package offers a guaranteed balanced protection, based on a Littelfuse

patent (US Patent 4,905,119). The ‘Y’ configuration offers identical metallic and longitudinal

protection all in one package.

SIDACtor devices enable equipment 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).

* “L” in part number indicates RoHS compliance. For non-RoHS compliant device, delete “L” from part number.

For individual “UA”, “UB”, and “UC” surge ratings, see table below.

** Asymmetrical

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.

• Listed SIDACtor devices are bi-directional. All electrical parameters and surge ratings apply to forward and reverse polarities.

• VDRM is measured at IDRM.

• VS is measured at 100 V/µs.

• Special voltage (VS and VDRM) and holding current (IH) requirements are available upon request.

• Device is designed to meet balance requirements of GTS 8700 and GR 974.
