DESCRIPTION
APPEARANCE
This SMBJ5.0-170A or SMBG5.0-170A series of surface mount 600 W
Transient Voltage Suppressors (TVSs) protects a variety of voltage-sensitive
components from destruction or degradation. It is available in J-bend design
(SMBJ) with the DO-214AA package for greater PC board mounting density or
in a Gull-wing design (SMBG) in the DO-215AA for visible solder connections.
It is also available in both unidirectional and bidirectional configurations with a
C or CA suffix part number as well as RoHS Compliant with an e3 suffix. 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.
NOTE: All SMB series are
equivalent to prior SMS package
identifications.
