Bidirectional TVS Diode Arrays from Littelfuse Protect High-Speed Interfaces from Damaging ESD

2017-03-06 | Return

CHICAGO, March 6, 2017 — Littelfuse, Inc., the global leader in circuit protection, today introduced a series of TVS Diode Arrays (SPA® Diodes) designed to protect electronic equipment from destructive electrostatic discharges (ESD). SP3042 Series Bidirectional Discrete TVS Diode Arrays include robust back-to-back TVS diodes fabricated using a proprietary silicon avalanche technology that can safely absorb repetitive ESD strikes up to the maximum level specified in the IEC 61000-4-2 international standard (±30kV contact discharge) without performance degradation. The back-to-back configuration provides symmetrical ESD protection for data lines when AC signals are present in a space-efficient 01005 footprint. The series’ low loading capacitance (0.35pF @ VR=0V, typ.) makes them ideal for protecting high-speed interfaces such as HDMI2.0, USB2.0, USB3.0 and eSATA.

Typical applications for the SP3042 Series include ESD protection for high-speed interfaces used in MIPI cameras and displays, DisplayPort1.3, eSATA, Internet of Things (IoT) modules, smartphones, external storage devices, ultrabook/notebook computers, tablets/eReaders and security modules.

“The small footprint of SP3042 Series TVS Diode Arrays allows them to protect high-speed interfaces while occupying minimal space on a printed circuit board,” said Tim Micun, global product manager/TVS Diode Arrays (SPA® Diodes) at Littelfuse. “Their low dynamic resistance enables them to respond quickly to prevent ESD damage.”

SP3042 Series TVS Diodes offer these key benefits:

。Bidirectional design ensures flexibility in assembly when placing parts on a printed circuit board (PCB).

。Provide linear frequency response performance across the working voltage, which is an important consideration for protecting high-speed interfaces.

。Low dynamic resistance (just 0.5Ω) allows them to respond quickly to ESD events.

。Provide robust ESD protection for high speed interfaces for voltages up to 30kV and current surges of up to 2A (8/20µs).

Availability

SP3042 Series TVS Diode Arrays are available in surface mount 01005-size flip chip packages in tape and reel format in quantities of 15,000. Sample requests can be placed through authorized Littelfuse distributors worldwide. For a listing of Littelfuse distributors, please visit Littelfuse.com.
