Lightning Surge Protection- SP4021 Series

SP4021

SP4021 Series

Description

Applications

The SP4021 devices integrate low capacitance steering

diodes with one or two zener diodes for unidirectional or

bidirectional protection, respectively, to protect against

ESD and lightning induced surge events. These devices

can safely absorb up to 25A per IEC61000-4-5 (tp=8/20μs)

without performance degradation and a minimum ±30kV

ESD per IEC61000-4-2 International Standard. The low

loading capacitance and high surge capability make it ideal

for protecting telecommunication ports such as Ethernet

and other high speed data interfaces.

Features

• ESD, IEC61000-4-2,

±30kV contact, ±30kV air

• EFT, IEC61000-4-4, 40A

(5/50ns)

• Lightning, IEC61000-4-5,

25A (t

=8/20μs)

• Low capacitance of 2.5pF

(@ V

=0V)

• Low leakage current

• Unidirectional and

Bidirectional conﬁguration

• Small SOD323 package

ﬁts 0805 footprints

•10/100/1000 Ethernet
