SMAJ5.0 thru SMAJ170CA, e3

SURFACE MOUNT 500 Watt

Transient Voltage Suppressor

S C O T T S D A L E D I V I S I O N

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-214AC or

DO-214BA. 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-214AC or BA

(SMAJ)

higher and lower power demands and special applications.
