Low Profile μClamp®
1-Line ESD protection
PROTECTION PRODUCTS - MicroClamp®
Features
Description
The μClamp® 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 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.
Transient protection for data lines to
IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (contact)
IEC 61000-4-4 (EFT) 40A (tp = 5/50ns)
Cable Discharge Event (CDE)
Ultra-small package (1.0 x 0.6 x 0.4mm)
Protects one data line
Low clamping voltage
Working voltage: 8V
Low leakage current
Solid-state silicon-avalanche technology
The μClamp0801T 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 8 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
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 Suppres-
sion of ESD.
Good circuit board layout is critical for the suppression
of ESD induced transients. The following guidelines are
recommended:
z
z
z
z
Place the TVS near the input terminals or connec-
tors to restrict transient coupling.
Minimize the path length between the TVS and the
protected line.
Minimize all conductive loops including power and
ground loops.
The ESD transient return path to ground should be
kept as short as possible.
z
z
Never run critical signals near board edges.
Use ground planes whenever possible.
