SOD-323 Single Line TVS Diode for ESD Protection
Description
TVS diodes are designed to replace multilayer
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 UMD05-323 is a Uni-Directional TVS that is
designed to provide high overvoltage protection
by clamping action and have instantaneous
response to transient overvoltages. The SOD-323
is a very small package which allows space
saving on high density printed circuit board and
also gives the designer the flexibility to protect
one line in applications where arrays are not
practical.
