The Littelfuse SP4020 and SP4021-01FTG-C series TVS diode arrays can safely provide up to 30 A (SP4020)/25 A (SP4021) protection against lightning induced surges and up to 750 W (SP4020)/600 W (SP4021) 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 (2.5 pF TYP) than competitive products. It is ideal for protecting telecommunications interfaces and other high-speed data without sacrificing signal integrity.
Feature
Superb surgeprotection Peak pulse power of 600W Lightning, IEC61000-4-5, 25A
Low capacitance of 2.5pF (typ)
Enhanced ESD capability ESD, IEC61000-4-2, ±30kV contact
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 far exceeds the highest level of the IEC61000-4-2 standard (±8kV) providing maximum reliability for equipment during installation and servicing
Provides low clamping voltages for sensitive chipsets, protecting them from catastrophic failure and maximizing system reliability
