Low Profile µClampTM
1-Line ESD protection
PROTECTION PRODUCTS - MicroClampTM
Description
Features
The µClamp 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, notebook computers, and other portable electronics. It features large cross-sectional area junctions for conducting
high transient currents. They offer desirable characteristics for board level protection including fast response
time, low operating and clamping voltage, and no device
degradation.
The µClampTM2401T is in a 2-pin 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 24 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.

Device Connection Options
Circuit Diagram
This device is designed to protect one data or power
supply line. 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 Suppression 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 connectors 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.
