Description

The SR70 consists of four, low capacitance, rail-to-rail

diodes that provide protection against ESD and lightning

surge events. These robust diodes can safely absorb up to

40A (tP=8/20μs) and repetitive ESD strikes at the maximum

level (Level 4) specified in the IEC 61000-4-2 international

standard without performance degradation.

Its low loading capacitance makes it ideal for protecting

high-speed data lines such as VDSL and VDSL2.

Features

• ESD, IEC61000-4-2 ,

±30kV contact discharge,

±30kV air discharge

• EFT, IEC61000-4-4, 80A

(tp=5/50ns)

• L ightning protection,

(tp=8/20µs)

• Low capacitance of 2.0pF

(TYP) per I/O

• L ow clamp voltage

• Small SOT143 (JEDEC TO-

253) packaging

Applications

• xDSL Lines

• Video Lines

• Customer Premises

Equipment

• 10/100/1000 Ethernet
