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
Power Ports
