The Clamp

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.

The clamp

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.

This device may be used to meet the ESD immunity

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

contact discharge).

... Therefore, these devices are compatible with both lead-free and SnPb assembly techniques. In addition, unlike other lead-free compositions, matte tin does not have any added alloys that can cause degradation of the solder joint. 2003 Semtech Corp. uClamp0501H Circuit Diagram 4 www.semtech.com ...
