SZNS6A5.0AFT3G Series
Description
The SZNS6AxxAFT3G 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 SZNS6AxxAFT3G 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.
