RailClamp

Low Capacitance TVS Diode Array

PROTECTION PRODUCTS

Features

Description

RailClamps are surge rated diode arrays designed to

protect high speed data interfaces. The SR series has

been specifically designed to protect sensitive compo-

nents which are connected to data and transmission

lines from overvoltage caused by ESD (electrostatic

discharge), EFT (electrical fast transients), and light-

ning.

! ESD protection to IEC 61000-4-2, Level 4

! Array of surge rated diodes with internal TVS Diode

! Protects two I/O lines

! Low capacitance (<10pF) for high-speed interfaces

! Low clamping voltage

! Low operating voltage: 5.0V

! Solid-state silicon-avalanche technology

The unique design of the SR series devices incorpo-

rates four surge rated, low capacitance steering diodes

and a TVS diode in a single package. During transient

conditions, the steering diodes direct the transient to

either the positive side of the power supply line or to

ground. The internal TVS diode prevents over-voltage

on the power line, protecting any downstream compo-

nents.

Mechanical Characteristics

! JEDEC SOT-143 package

! UL 497B listed

! Molding compound flammability rating: UL 94V-0

! Marking : R05

! Packaging : Tape and Reel per EIA 481

The low capacitance array configuration allows the user

to protect two high-speed data or transmission lines.

The low inductance construction minimizes voltage

overshoot during high current surges.

Applications

! USB Power & Data Line Protection

! Ethernet 10BaseT

! I²C Bus Protection

! Video Line Protection

! T1/E1 secondary IC Side Protection

! Portable Electronics

! Microcontroller Input Protection

! WAN/LAN Equipment

! ISDN S/T Interface
