The Clamp
(TVS) are designed to replace multilayer 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. They are are designed to protect sensitive
semiconductor components from damage or upset due
to electrostatic discharge (ESD), lightning, electrical
fast transients (EFT), and cable discharge events
(CDE).
The Clamp
proprietary EPD process technology. The EPD process
provides low standoff voltages with significant reduc-
tions in leakage currents and capacitance over silicon-
avalanche diode processes. They feature a true
operating voltage of 3.3 volts for superior protection
when compared to traditional pn junction devices.
The Clamp3301D is in a SOD-323 package and will
protect one unidirectional line. They give the designer
the flexibility to protect one line in applications where
arrays are not practical.
They may be used to meet the ESD immunity require-
ments of IEC 61000-4-2, Level 4 (±15kV air, ±8kV
contact discharge).
