Nxx2AT23
300W Surface Mount TVS Diodes
The Nxx2AT23 Series of transient voltage
FEATURES
suppressors are designed to protect
components which are connected to data and
transmission lines from over voltages caused
by electrostatic discharge (ESD), electrical
fast transients (EFT), and induced lightning.
