SCOTTSDALE DIVISION
SURFACE MOUNT 600 Watt
Transient Voltage Suppressor
DESCRIPTION
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. 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.
