UMAF5.0A thru UMAF170CA
ULTRAMITE™ SURFACE MOUNT 500 Watt
Transient Voltage Suppressor 5.0 to 170 V
ENVIRONMENTALLY LEAD-FREE
DESCRIPTION
PACKAGE
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
BA package outlines except with a much lower profile height. Its robust
www.DataSheet4Uco.cnofmiguration 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.

FEATURES
APPLICATIONS / BENEFITS
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-PRF-
19500 for JAN, JANTX, JANTXV, and JANS are
available by adding MQ, MX, MV, or MSP prefixes
respectively to part numbers
Protects sensitive components such as IC’s, CMOS,
Bipolar, BiCMOS, ECL, DTL, T 2L, etc.
Protection from switching transients & induced RF
Compliant to IEC61000-4-2 and IEC61000-4-4 for ESD
and EFT protection respectively

42 Ohms source impedance:
Class 1: UMAF5.0 to UMAF100A or CA
Class 2: UMAF5.0 to UMAF51A or CA
Class 3: UMAF5.0 to UMAF24A or CA
Class 4: UMAF5.0 to UMAF12A or CA
§ Secondary lightning protection per IEC61000-4-5 with
12 Ohms source impedance:
