SMAJ5.0 thru SMAJ170CA

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-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

DO-214AB or AC

(SMAJ)

products to meet higher and lower power demands and special applications.

IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
