PROTECTION PRODUCTS - MicroClamp®
Description
Features
The uClamp series of TVS arrays are designed to protect sensitive electronics from damage or latch-up due
to ESD. They are designed to replace multilayer varistors
(MLVs) in portable applications. They feature large crosssectional area junctions for conducting high transient
currents and offer superior electrical characteristics
such as lower clamping voltage and no device degradation when compared to MLVs. They offer desirable
characteristics for board level protection including fast
response time, low operating and clamping voltage, and
no device degradation.
The µClampTM0511PQ is in a 2-pin, 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 ±5 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.
The uClamp0511PQ is qualified to AEC-Q100 Grade 1 for
Automotive use.

Equivalent Circuit Diagram
These TVS diodes are 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 abd below ground.
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:
 Place the TVS near the input terminals or connectors
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.
 Never run critical signals near board edges.
 Use ground planes whenever possible.
