NSA5.0AT3G

400 Watt Peak Power Zener

Transient Voltage

Suppressor

Unidirectional

The NSA5.0AT3G is designed to protect voltage sensitive

components from high voltage, high energy transients. It has

excellent clamping capability, high surge capability, low zener

impedance and a fast response time. The NSA5.0AT3G 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.
