µClamp^TM

1-Line ESD Protection

PROTECTION PRODUCTS - MicroClamp^TM

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 PDAs. It features large cross-sectional area junc-

tions for conducting high transient currents. It offers

superior electrical characteristics such as lower clamp-

ing voltage and no device degradation when compared

to MLVs. They offer desirable characteristics for board

level protection including fast response time, low oper-

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

Protects one I/O or power line

Low clamping voltage

Working voltage: 12V

Low leakage current

Solid-state silicon-avalanche technology

The µClamp^TM1201H is in a 2-pin, RoHS compliant,

SOD-523 package. The leads are finished with lead-

free matte tin. Each device will protect one line oper-

ating at 12 volts. It gives the designer the flexibility 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.
