The NS6AxxAFT3G series is designed to protect voltage sensitive  
components from high voltage, high energy transients. This device  
has excellent clamping capability, high surge capability, low zener  
impedance and fast response time. The NS6AxxAFT3G series is  
ideally suited for use in computer hard disk drives, communication  
systems, automotive, numerical controls, process controls, medical  
equipment, business machines, power supplies and many other  
industrial/consumer applications.
