SMAJP4KE6.8 thru SMAJP4KE400CA, e3  
TRANSIENT VOLTAGE SUPPRESSOR  
S C O T T S D A L E D I V I S I O N  
DESCRIPTION  
PACKAGE  
This Transient Voltage Suppressor (TVS) series is an economical molded  
surface mount package with very low thermal resistance due to its unique  
axial subassembly. It is used for automotive applications and others to  
protect voltage sensitive components from destructive or partial degradation.  
They have a peak pulse power rating of 400 watts for 1 ms as depicted in  
Figures 1 and 2. The package is configured for easy pick and place onto PC  
Boards for automated handling. The J-bend terminations also provide stress  
relief for use on a variety of PC Board materials.  
DO-214AC or BA  
(SMAJ)  
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
