µClamp^TM

1-Line ESD protection

PROTECTION PRODUCTS - MicroClamp

Features

Description

The µClamp^TMseries of TVS arrays are designed to protect

sensitive electronics from damage or latch-up due to ESD.

It is designed to replace multilayer varistors (MLVs) in por-

table applications such as cell phones, notebook comput-

ers, and PDA’s. It features large cross-sectional area junc-

tions for conducting high transient currents. It offers su-

perior electrical characteristics such as lower clamping volt-

age and no device degradation when compared to MLVs.

They offer desirable characteristics for board level protec-

tion including fast response time, low operating and clamp-

ing 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 SOD-523 package (1.7 x 0.9 x 0.7mm)

! Protects one I/O or power line

! Low clamping voltage

! Working voltage: 5V

! Low leakage current

! Solid-state silicon-avalanche technology

The µclamp^TM0501H is in a ultra-small SOD-523 pack-

age ideal for use in portable electronics such as cell

phones, PDA’s, notebook computers, and digital

cameras. It will protect one unidirectional line operat-

ing at 5 volts. It gives the designer the flexibility to

protect one line in applications where arrays are not

practical. Additionally, it may be “sprinkled” around the

board in applications where board space is at a pre-

mium.

Mechanical Characteristics

! EIAJ SOD-523 package

! Molding compound flammability rating: UL 94V-0

! Marking : Marking code, cathode band

! Packaging : Tape and Reel per EIA 481

! Lead Finish: Matte tin

Applications

! Cellular Handsets & Accessories

! Cordless Phones

! Personal Digital Assistants (PDA’s)

! Notebooks & Handhelds

! Portable Instrumentation

! Digital Cameras

This device may be used to meet the ESD immunity

requirements of IEC 61000-4-2, Level 4 (15kV air, 8kV

contact discharge).

! Peripherals

! MP3 Players
