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 PDAs. It features large cross-sec-

tional area junctions for conducting high transient cur-

rents. It offers superior electrical characteristics such

as lower clamping voltage and no device degradation

when compared to MLVs. They offer desirable charac-

teristics for board level protection including fast response

time, low operating and clamping voltage, and no device

degradation.

The µClamp^TM1201P is in a 2-pin, RoHS/WEEE compli-

ant, SLP1006P2 package. It measures 1.0 x 0.6 x

0.50mm. 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 12 volts. It gives the

designer the flexibility to protect single lines in applica-

tions 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 Applications

makes them ideal for use in portable applications such

as cellular phones, digital cameras, and MP3 players.

Applications Information

Device Connection Options

Circuit Diagram

These TVS diodes are designed to protect one data,

I/O, 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.
