UMA5.0A thru UMA170CA ULTRAMITETM SURFACE MOUNT 500 Watt Transient Voltage Suppressor 5.0 to 170 V SCOTTSDALE DIVISION PACKAGE BA package outlines except with a much lower profile height. Its robust configuration in a "2010" style MELF package prevents damage to extendedlead 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.
