The SP4021 Series TVS Diode Arrays can safely provide up to 25A protection against lightning induced surges and up to 600W of power handling capability. This revolutionary design offers 1.5x 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 600W

Low capacitance of 2.5pF (typ)

Enhanced ESD capability

Low dynamic resistance

RDYN is 0.52Ω for SP4021

Benefits:

Compared to similar market solutions, the SP4021 Series provides remarkably more overhead to electrical threats defined by regulatory standards

-1.5x 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
