Mechanical Characteristics

The SDxxC TVS diodes are designed to replace multi-

layer varistors (MLVs) in portable applications such as

cell phones, notebook computers, and PDA’s. 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).
