Lightning Surge Protection - SP3304N Series

Description

Applications

The SP3304N integrates 4 channels of low capacitance

diodes with an additional zener diode to protect sensitive

I/O pins against lightning induced surge events and

ESD. This robust device can safely absorb up to 20A per

IEC61000-4-5 (t

=8/20μs) without performance degradation

and a minimum ±30kV ESD per IEC61000-4-2 international

standard. The low loading capacitance makes the SP3304N

ideal for protecting high-speed signal pins.

Features

• ESD, IEC61000-4-2,

±30kV contact, ±30kV air

• EFT, IEC61000-4-4, 40A

=5/50ns)

• Lightning, IEC61000-4-5,

20A (t

=8/20µs)

• Low capacitance of 3.5pF

(TYP) per I/O

• Low leakage current of

1µA (MAX) at 3.3V

• 10/100/1000 Ethernet

Interfaces

• Customer Premise

Equipment (CPE)

• VoIP Phones

• Set Top Boxes

• PBX Systems
