SURFACE MOUNT 500 Watt
Transient Voltage Suppressor

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 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
DO-214AB or AC
(SMAJ)
higher and lower power demands and special applications.
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com

For Bidirectional device types indicate a C or CA suffix after the part number. (i.e.: SMAJ170CA or SMAJ170C). Bidirectional
capacitance is half that shown in figure 4 at zero volts.
Microsemi Corp’s SMA series (500 W) surface mountable packages are designed specifically for transient voltage suppression. The
wide leads assure a large surface contact for good heat dissipation, and a low resistance path for surge current flow to ground. These
high speed transient voltage suppressors can be used to effectively protect sensitive components such as integrated circuits and MOS
devices.
