SIDACtor Protection Thyristors Battraxe Series – Single Port Negative MS-013

Category: Electronics, Littelfuse Inc, Telecom ICS

Description

The Battraxe Series, specifically designed by Littelfuse for Single Line Interface Circuit (SLIC) protection applications, features programmable SIDACtor Protection Thyristors that cater to overvoltage protection needs. Offering a notable trait, these components are referenced to a negative voltage source, while internal diodes shield against positive surge events.

Features and Benefits

Key features include a low voltage overshoot, which promotes device stability during voltage fluctuation events. The product also boasts a low on-state voltage, and incorporates integrated diodes protecting against positive voltage surges. Notably, the device maintains its surge protection integrity after enduring multiple surge incidents. Moreover, the Battraxe series offers single-port protection and employs a lead-free, RoHS-compliant design, recognized by meeting Pb-free E3 interconnect standards. In case of extreme surges, it is designed to fail into a short circuit state, hence preventing open circuit failures which can be more damaging.

Applicable Global Standards

The product aligns with diverse global standards, such as TIA-968-A, GR 1089 Core, TIA-968-B, IEC 61000-4-5, ITU’s K.20/21 Enhanced and Basic levels, and various YD/T standards, ensuring broad compliance and integration capability in telecom infrastructure.

Agency Approvals

The series has obtained agency approval from UL, confirmed by the Agency File Number E133083.

Electrical Characteristics

Key electrical parameters include the DRM (peak repetitive off-state voltage) and IDRM (off-state leakage current), with DRM values at 100 mA max and IDRM values at 2.2 A max across various models within the series. Capacitance range is reported with minimum and maximum values tailored to specific part numbers which differ by suffixes that designate packaging format — ‘TP’ for Tube Pack and ‘RP’ for Reel Pack. It is important to note that these components are not compatible with positive ringing systems and that all values are measured at 25°C unless specified otherwise.

Pinout Designation and Schematic Symbol

The displayed diagram denotes Pin 6 as “No Connect”, whilst the other pins are assigned specific voltage reference points for device operation and schematic representation.
