Transient Voltage Suppressor 5.0 to 170 V

DESCRIPTION
PACKAGE
These 500 watt transient voltage suppressors offer capabilities only found in larger
packages. They are used for protecting against a variety of transients from inductive
switching environments or lower levels of induced secondary lightning effects of
IEC61000-4-5. It offers the same size footprint as the popular DO-214AC or
BA package outlines except with a much lower profile height. Its robust
configuration in a “2010” style MELF package prevents damage to extended-
lead terminals and virtually eliminates inductive parasitics from fast rise-time
transients with very short internal/external conduction paths. They are also very
effective in protection from ESD or EFT per IEC61000-4-2 and IEC61000-4-4.
