PROTECTION PRODUCTS - MicroClampTM
Description
The μClampTM series of TVS arrays are designed to pro-
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 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 μClampTM0502P is in a 3-pin, RoHS/WEEE compli-
ant, SLP1006P3 package. It measures 1.0 x 0.6 x
0.5mm. The leads are spaced at a pitch of 0.65mm
and are finished with lead-free NiPdAu. Each device
will protect two lines operating at 5 volts. It gives the
designer the flexibility to protect single lines in applica-
tions 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.

Applications Information
Device Connection Options
These TVS diodes are designed to protect two data,
lines. The device is unidirectional and may be used on
lines where the signal polarity is above ground. The
cathode band should be placed towards the line that is
to be protected.
Circuit Board Layout Recommendations for Suppres-
sion of ESD.
Good circuit board layout is critical for the suppression
of ESD induced transients. The following guidelines are
recommended:
z Place the TVS near the input terminals or connec-
tors to restrict transient coupling.
z Minimize the path length between the TVS and the
protected line.
z Minimize all conductive loops including power and
ground loops.
z The ESD transient return path to ground should be
kept as short as possible.
z Never run critical signals near board edges.
z Use ground planes whenever possible.
