1SMA5.0AT3 Series  
400 Watt Peak Power Zener  
Transient Voltage Suppressors  
Unidirectional*  
The SMA 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 SMA series is supplied in  
ON Semiconductor’s exclusive, cost-effective, highly reliable  
Surmetict 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.
