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 . 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 .. 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. Ultra Mite IMPORTANT: For the most current data, consult MICROSEMI’s website: http://.microsemi. 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 height profile (approx 1 mm) - Available on Tape and Reel - Built-in stress relief with similar COE as PC boards - Lead-Free construction externally and internally - Optional Lead-Tin finish (UMA5.0A-170CA) - Options for screening in accordance with MIL-PRF19500 for JAN, JANTX, JANTXV, and JANS are available by adding MQ, MX, MV, or MSP prefixes respectively to part numbers APPLICATIONS / BENEFITS - Protects sensitive ponents such as IC’s, CMOS, 2 Bipolar, Bi CMOS, ECL, DTL, T L, etc. -...
