The SP4020 Series TVS Diode Arrays can safely provide up to 30A protection against lightning induced surges and up to 750W of power handling capability. This revolutionary design offers 2x the power handling capability of alternative solutions, and yields a 16% improvement in low loading capacitance (2.5pF TYP) than competitive products. Ideal for protecting telecommunications interfaces and other high-speed data interfaces without sacrificing signal integrity.

Superb surge protection

Peak pulse power of 750W

Low capacitance of 2.5pF (typ)

Enhanced ESD capability

Low dynamic resistance

RDYN is 0.7Ω for SP4020

Benefits:

Compared to similar market solutions, the SP4020 Series provides remarkably more overhead to electrical threats defined by regulatory standards

-2x higher power handling capability

16% lower capacitance than other solutions helps to preserve signal integrity and minimize data loss while offering a more robust device against electrical threats

Enhanced ESD protection provides maximum reliability for equipment during installation and servicing

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

Applications:

10/100/1000 Ethernet

T1/E1/T3/E3 Data Lines

USB1.1/2.0
