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 Surmetic� 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.
The 1SMA5.0AT3 Series consists of unidirectional plastic surface mount Zener overvoltage transient suppressors designed to protect voltage-sensitive components from high voltage, high energy transients. These devices feature excellent clamping capability, high surge capability, low zener impedance, and a fast response time of typically less than 1 ns. They are supplied in ON Semiconductor's Surmetic package, which is suitable for top slide or bottom circuit board mounting.
