DESCRIPTION
PACKAGE
This SMAJ5.0-170A series of surface mount 500 W Transient Voltage
Suppressors (TVSs) protects a variety of voltage-sensitive components from
destruction or degradation. The package outline is similar to the DO-214AB or
DO-214AC. It is also available in a unidirectional configuration or as bidirectional
with a C or CA suffix part number. Their response time is virtually instantaneous.
As a result, they can be used for protection from ESD or EFT per IEC61000-4-2
and IEC61000-4-4, or for inductive switching environments and induced RF
protection. They can also protect from secondary lightning effects per IEC61000-
4-5 and class levels defined herein. Microsemi also offers numerous other TVS
products to meet higher and lower power demands and special applications.
DO-214AB or AC
(SMAJ)

FEATURES
APPLICATIONS / BENEFITS
Selections for 5.0 to 170 volts standoff voltages (VWM)
Suppresses transients up to 500 watts @ 10/1000 s
(see Figure 1)
Fast response
Optional 100% screening for avionics grade is
available by adding MA prefix to part number for added
100% temperature cycle -55
oC to +125oC (10X) as well
as surge (3X) and 24 hours HTRB with post test VZ &
IR (in the operating direction for unidirectional or both
directions for bidirectional)
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.
Axial-lead equivalent packages for thru-hole mounting
available as P5KE6.8 to P5KE170CA (consult factory for
other surface mount options)
Moisture classification is Level 1 with no dry pack
required per IPC/JEDEC J-STD-020B
Economical surface mount
Available in Unidirectional or as Bidirectional
construction with a C or CA suffix
Protects sensitive components such as IC’s,
CMOS, Bipolar, BiCMOS, ECL, DTL, T
2L, etc.
