Low Voltage μClamp^®

for Gigabit Ethernet

PROTECTION PRODUCTS - MicroClamp^®

Features

Description

The μClamp^®3312T TVS diode is specifically designed

to meet the performance requirements of Gigabit

Ethernet interfaces. They are designed to protect

sensitive PHY chips from damage or upset due to

electrostatic discharge (ESD), lightning, electrical fast

transients (EFT), and cable discharge events (CDE).

High ESD withstand Voltage: +/-30kV (Contact/Air)

per IEC 61000-4-2

Able to withstand over 1000 ESD strikes per IEC

61000-4-2 Level 4

Flow-through design simplifies layout

Protects two line pairs

Low reverse current: 10nA typical (VR=3.3V)

Low variation in capacitance vs. bias voltage:

1.3pF Typical (VR = 0 to 3.3V)

Working voltage: 3.3V

Solid-state silicon-avalanche technology

The μClamp3312T is constructed using Semtech’s low

voltage EPD process technology. The EPD process

provides low operating voltages with significant reduc-

tions in leakage current and capacitance over silicon-

avalanche diode processes. The device features low

variation in capacitance over bias for stable operation

on GbE lines. This means the μClamp3312T will

introduce zero traffic frame errors on GbE interfaces

up to a PHY temperature of 120^oC (100M Cat 5/5e

Cable). The μClamp3312T also features high surge

capability and is designed to be placed between the

magnetics and the PHY chip. In this configuration, the

device can withstand intra-building lightning surges per

Telcordia GR-1089.

Mechanical Characteristics

SLP2010N8T package

Pb-Free, Halogen Free, RoHS/WEEE Compliant

Nominal Dimensions: 2.0 x 1.0 x 0.4 mm

Lead Finish: NiPdAu

Molding compound flammability rating: UL 94V-0

Marking: Marking code

Packaging: Tape and Reel

The μClamp3312T is in a 8-pin SLP2010N8T package.

It measures 2.0 x 1.0 x 0.4mm. The leads are spaced

at a pitch of 0.5mm and are finished with lead-free

NiPdAu. Each device will protect two line pairs operat-

ing at 3.3 volts. It gives the designer the flexibility to

protect multiple lines in applications where space is at

a premium. The small size and easy layout of the

uClamp3312T make it ideal for use in RJ-45 connec-

tors with integrated magnetics.
