UMAFxxxA

UMAF5.0A thru UMAF170CA ULTRAMITE™ SURFACE MOUNT 500 Watt SCOTTSDALE DIVISION Transient Voltage Suppressor 5.0 to 170 V ENVIRONMENTALLY LEAD-FREE W W W . Microsemi . COM DESCRIPTION These 500 watt transient voltage suppressors offer power-handling capabilities only found in larger packages. They are also environmentally Lead-Free both externally and internally. 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 PACKAGE configuration www.DataSheet4U.com BA package outlines except with a much lower profile height. Its robust 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. UltraMite IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com FEATURES Available as a unidirectional or bidirectional device (bidirectional with CA suffix) Fast response time Suppresses transients up to 500 W @ 10/1000 µs (see Figure 1, 2, and 3). Robust 2010 MELF style flat package configuration for accurate pick-and-place handling Fits same small narrow PCB pad layouts as “SMAJ” packages in JEDEC DO-214AC (or BA) Very low heigh...
