UMA5.0A thru UMA170CA ULTRAMITE™ SURFACE MOUNT 500 Watt Transient Voltage Suppressor 5.0 to 170 V SCOTTSD A L E DIVISION WWW.Microsemi .COM UMA5.0A – UMA170CA DESCRIPTION PACKAGE These 500 watt transient vo ltage su ppressors offer cap abilities o nly fo und in l arger packages. They are us ed for protectin g against a variet y of transients from inductiv e switching e nvironments or l ower l evels of induc ed s econdary l ightning effects of IEC61000-4-5. It offers the same size footprint a s the popular DO-214AC or BA packag e outline s ex cept with a m uch l ower profile heig ht. Its ro bust configuration in a “2010” style MELF package prevents damage to extended- lead terminals and virtually eliminates inductive parasitics from fa st 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. UltraMite™ IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com FEATURES APPLICATIONS / BENEFITS
