1SMA5.0AT3G Series  
Description  
The 1SMA5.0AT3G series is designed to protect voltage  
sensitive components from high voltage, high energy  
transients. They have excellent clamping capability, high  
surge capability, low zener impedance and fast response  
time. The 1SMA5.0AT3G series is supplied in the Littelfuse  
exclusive, cost-effective, highly reliable package and is  
ideally suited for use in communication systems,  
automotive, numerical controls, process controls, medical  
equipment, business machines, power supplies and many  
other industrial/consumer applications.
