TVS diodes are designed to protect sensitive
electronics from damage or latch-up due to ESD. They
are designed to replace 0201 size multilayer varistors
(MLVs) in portable applications such as cell phones, note-
book computers, and other portable electronics. They
feature large cross-sectional area junctions for conduct-
ing high transient currents. These devices offer desir-
able characteristics for board level protection including
fast response time, low operating and clamping voltage,
and no device degradation.

0551Y features extremely good ESD protection
characteristics highlighted by low typical dynamic resis-
tance of 0.37 Ohms, low peak ESD clamping voltage,
and high ESD withstand voltage (+/-20kV contact per
IEC 61000-4-2). Low typical capacitance (6.9pF at
VR=0V) minimizes loading on sensitive cirucuits. Each
device will protect one data or power line operating at 5
Volts.
μClamp0551Y is in a 2-pin SLP0603P2X3E package
measuring 0.6 x 0.3 mm with a nominal height of
0.25mm. Leads are finished with lead-free NiAu. The
small package gives the designer the flexibility to
protect single lines in applications where arrays are not
practical. 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 tablet PC’s.
