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. It features large cross-
sectional 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 µClampTM1211P is in a 2-pin, RoHS/WEEE
compliant, SLP1006P2 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 one bidirectional 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.

Applications Information
Device Connection Options
This TVS diode is designed to protect one data,
I/O, or power supply line. The device is bidirectional
and may be used on lines where the signal polarity can
go above and below ground. The device is
symmetrical, and therefore, the orientation of the
device is not critical.
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.
