Low-Capacitance TVS Diode Arrays protect telecom interfaces.

Press Release Summary:



Offered in SOD323 packaging, SP4020 and SP4021 Series discrete low capacitance TVS Diode Arrays (SPA® Diodes) safeguard telecom interfaces from lightning-induced surges and ESD damage. Arrays integrate low capacitance steering diodes with either one or two TVS diodes to provide unidirectional or bidirectional protection from electrical threats for 3.3 V (SP4020) and 5 V (SP4021) applications. Loading capacitance helps preserve signal integrity and minimize data loss.



Original Press Release:



New Low Capacitance TVS Diode Arrays from Littelfuse Offer Greater Protection from Surges, ESD than Similar Components



High power handling capabilities safeguard modern telecommunications interfaces



CHICAGO — Littelfuse, Inc., the global leader in circuit protection, has introduced two series of discrete low capacitance TVS Diode Arrays (SPA® Diodes) optimized to help telecommunications circuit and hardware designers safeguard  telecom interfaces from lightning-induced surges and electrostatic discharge (ESD) damage. The SP4020 and SP4021 Series TVS Diode Arrays integrate low capacitance steering diodes with either one or two TVS diodes to provide unidirectional  or bidirectional protection from electrical threats for 3.3V (SP4020) and 5V (SP4021) applications. They offer a loading capacitance that is 16 percent lower than other solutions on the market, which helps preserve signal integrity and minimize data loss. The SP4020 Series provides twice the power dissipation capability as similar market solutions; the SP4021 Series offers one-and-one-half times higher power dissipation capability than other offerings. They can safely absorb high levels of lightning-induced surge current and are ideal for interfaces including, but not limited to T1/E1/T3/E3, 10/100/1000 Ethernet, USB 1.1/2.0, , etc.



“The SP4020 and SP4021 TVS Diode Arrays offer superb surge and ESD protection that will help design engineers comply with and exceed all the relevant industry standards such as IEC61000-4-2 (Level 4) and IEC61000-4-5 (Class 2),” said Chad Marak, Product Line Director for the TVS Diode Array line. “Their power handling capability and low dynamic resistance ensures exceptional clamping performance to protect today’s sensitive chipsets from premature failure.”



Benefits



Provides greater overhead to electrical threats as defined by regulatory standards than similar market solutions: 2x higher (SP4020) and 1.5x higher (SP4021) power handling capability



Helps preserve signal integrity and minimize data loss



Exceeds the highest level of the IEC61000-4-2 standard (±8kV) to provide higher equipment reliability during installation and servicing



Provides low clamping voltages for sensitive chipsets, protecting them from catastrophic failure and maximizing system reliability



Availability

The SP4020 and SP4021 Series are available in SOD323 packaging in reels of 3,000. Samples are available now; sample requests can be placed through authorized Littelfuse distributors worldwide. For a listing of Littelfuse distributors, please visit littelfuse.com.
