Mechanical Characteristics
The SDxxC TVS diodes are designed to replace multi-
layer varistors (MLVs) in portable applications such as
cell phones, notebook computers, and PDAs. They
offer superior electrical characteristics such as lower
clamping voltage and no device degradation when
compared to MLVs. The SDxxC series TVS diodes are
designed to protect sensitive semiconductor compo-
nents from damage or upset due to electrostatic
discharge (ESD) and other voltage induced transient
events.
The SDxxC is in a SOD-323 package and will protect
one bidirectional line. They are available with working
voltages of 5 - 24 volts. These devices will fit on the
same PCB pad area as an 0805 MLV device. They give
the designer the flexibility to protect one line in applica-
tions where arrays are not practical. Additionally, it
may be sprinkled around the board in applications
where board space is at a premium.
They may may be used to meet the ESD immunity
requirements of IEC 61000-4-2, Level 4 (15kV air, 8kV
contact discharge).
