CHICAGO, March 6, 2017Littelfuse, 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.
