JEDEC REGISTERED PACKAGE OUTLINE  
DESCRIPTION  
The SMAJ series are TRANSILTM diodes designed  
specifically for protecting sensitive equipment  
against transient overvoltages. The SMA package  
allows save spacing on high density printed circuit  
boards.  
SMA  
(JEDEC D0214 AC)  
Transil diodes provide high overvoltage protection  
by clamping action. Their instantaneous response  
to transient overvoltages makes them particularly  
suited to protect voltage sensitive devices such  
as MOS Technology and low voltage supplied  
IC’s.
