SZNS6A5.0AFT3G Series
500 Watt Peak Power Zener
Transient Voltage
Suppressors
Unidirectional
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.
