The μClamp

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 other portable electronics. It fea-

tures large cross-sectional area junctions for conducting

high transient currents. They offer desirable character-

istics for board level protection including fast response

time, low operating and clamping voltage, and no device

degradation.

The μClamp

ant, SLP1006P2T package. It measures 1.0 x 0.6 mm

with a nominal height of only 0.4mm. 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 flexibil-

ity 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.
