SMA5.0AT3G Series Pb Description The SMA5.0AT3G series is designed to protect voltage sensitive components from high voltage, high energy transients.

1 SMA5.0AT3G Series Pb Description The SMA5.0AT3G 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 SMA5.0AT3G 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.
