This new broadband protection device from Littelfuse provides overvoltage protection for applications such as 10/100/1000 BaseT Ethernet, T3/E3 DS3 interfaces, ADSL2+, and VDSL2+. This new protector combines the TVS diode element with a diode rectifier bridge to provide both longitudinal and differential protection in one package. This design innovation results in a capacitive loading characteristic that is log-linear with respect to the signal voltage across the device. This reduces intermodulation (IM) distortion caused by a typical solid-state protection solution. The application schematic provides the connection information.
Feature:
RoHS compliant
MS-012 surface mount package (JEDEC SO-8)
Low insertion loss, log-linear capacitance
Combined longitudinal and metallic protection
Clamping speed of nanoseconds
Pin-to-Pin compatible with SEMTECH LC03-6
UL 94V-0 epoxy molding
Pending UL recognized component
Low clamping voltage
Applications:
T1/E1 Line cards
T3/E3 and DS3 Interfaces
STS-1 Interfaces
10/100/1000 BaseT Ethernet

Asymmetrical Modified MS-013 Balanced Three-chip SIDACtor® Device This balanced protector is a surface mount alternative to the modified TO-220 package. Based on a six-pin surface mount SOIC package, it uses Littelfuse's patented "Y" (US Patent 4,905,119) configuration. It is available in surge current ratings up to 500A.
SIDACtor devices are used to enable equipment to meet various regulatory requirements including GR 1089, ITU K.20, K.21, and K.45, IEC 60950, UL 60950, and TIA-968 (formerly known as FCC Part 68).
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 & surge ratings apply to forward and reverse polarities.
Vdrm is measured at Idrm.
Vs is measured at 100 V/µs.
Special voltage (Vs & Vdrm) and holding current (Ih) requirements are available upon request.
Off-state capacitance is measured between Pins 1-3 and 1-4 at 1 MHz with a 2 V bias.
Designed to meet balance requirements of GTS 8700 and GR 974.

These devices are designed to help protect sensitive telecommunication equipment from the hazards caused by overvoltage faults stemming from lightning, power contact, and power induction. They have a high electrical surge capability to help protect against transient faults and a high off-state impedance, rendering them virtually transparent during normal system operation.
