ULTRAMITE™ SURFACE MOUNT 500 Watt

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.
