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
