Description

The UClamp series 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 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 UCLAMP1201P is in a 2-pin, RoHS/WEEE compliant,

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 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.
