SP4042 Series 3.3V TVS Diode Arrays from Littelfuse Help Prevent Equipment Damage Due to Lightning-Induced Surge Events, ESD

Two channels of protection for Ethernet interfaces, CPE, Carrier Class Equipment, and PBX systems

CHICAGO--()--Littelfuse, Inc., the global leader in circuit protection, has introduced the SP4042 Series TVS Diode Array, which are designed specifically to protect sensitive electronic equipment from damage due to lightning-induced surge events and electrostatic discharges (ESD). The SP4042 Series integrates low capacitance steering diodes with a TVS diode to provide two channels of protection. This robust device can safely absorb up to 120A per IEC61000-4-5 (tP= 2/10μs) without performance degradation and a minimum ±30kV ESD per IEC61000-4-2 international standard. Low loading capacitance (11pF per line) makes the SP4042 Series ideal for protecting 10/100/1000 Ethernet interfaces, Customer Premise Equipment (CPE), Carrier Class Equipment, and PBX systems.

“With leakage current of just 0.1µA, the SP4042 Series offers 90 percent lower leakage current than competitive devices.”

“The SP4042 Series was developed in collaboration with some key customers, who had a variety of implementation concerns, including leakage current, which negatively affects signal integrity,” said Tim Micun, product manager/TVS Diode Arrays (SPA® Diodes). “With leakage current of just 0.1µA, the SP4042 Series offers 90 percent lower leakage current than competitive devices.”

All SP4042 Series TVS Diodes offer these key benefits:

  • With a peak pulse power rating of 2500W, the SP4042 Series provides excellent surge protection, ensuring the headroom needed to guard against electrical threats defined by regulatory standards.
  • Low capacitance of 11pF per line preserves signal integrity and minimizes data loss while offering a more robust device against electrical threats.
  • Enhanced ESD capability (±30kV contact, ±30kV air) permits manufacturers to provide ESD protection beyond the maximum level stated in the IEC standard and protects against a multitude of other threats to ensure product reliability in the field.
  • Low leakage current of 0.1μA at 3.3V provides enhanced signal integrity, as leakage is often an indicator for the device “turning on.”

Availability

The SP4042 Series is packaged in a μDFN-10 package and is provided in tape & reel packaging in quantities of 3,000. Sample requests can be placed through authorized Littelfuse distributors worldwide. For a listing of Littelfuse distributors, please visit Littelfuse.com.
