PROTECTION PRODUCTS - MicroClamp^TM

Features

Description

The µClamp^TMseries of TVS arrays are designed to pro-

tect sensitive electronics from damage or latch-up due

to ESD. It is designed to replace multilayer varistors

(MLVs) in portable applications such as cell phones, note-

book computers, and other portable electronics. It fea-

tures large cross-sectional area junctions for conducting

high transient currents. They offer desirable character-

istics for board level protection including fast response

time, low operating and clamping voltage, and no device

degradation.

Transient protection for data lines to

IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (contact)

IEC 61000-4-4 (EFT) 40A (tp = 5/50ns)

Cable Discharge Event (CDE)

Ultra-small package (1.0 x 0.6 x 0.4mm)

Protects one data line

Low clamping voltage

Working voltage: 24V

Low leakage current

Solid-state silicon-avalanche technology

The µClamp^TM2401T is in a 2-pin, RoHS/WEEE compli-

ant, SLP1006P2T package. It measures 1.0 x 0.6 mm

with a nominal height of only 0.4mm. The leads are

spaced at a pitch of 0.65mm and are finished with

lead-free NiPdAu. Each device will protect one line

operating at 24 volts. It gives the designer the flexibil-

ity to protect single lines in applications where arrays

are not practical. They may be used to meet the ESD

immunity requirements of IEC 61000-4-2, Level 4

(±15kV air, ±8kV contact discharge). The combination

of small size and high ESD surge capability makes

them ideal for use in portable applications such as

cellular phones, digital cameras, and MP3 players.

Device Connection Options

Circuit Diagram

This device is designed to protect one data or power

supply line. The device is unidirectional and may be

used on lines where the signal polarity is above ground.

The cathode band should be placed towards the line

that is to be protected.

Circuit Board Layout Recommendations for Suppres-

sion of ESD.

Good circuit board layout is critical for the suppression

of ESD induced transients. The following guidelines are

recommended:

Place the TVS near the input terminals or connec-

tors to restrict transient coupling.

Minimize the path length between the TVS and the

protected line.

Minimize all conductive loops including power and

ground loops.

The ESD transient return path to ground should be

kept as short as possible.

Never run critical signals near board edges.

Use ground planes whenever possible.
