DESCRIPTION
The 422E/B series of protection is a two stage transient voltage protector providing primary and
secondary protection against lightning, inductive switching and electrostatic discharge (ESD)
transient threats. The first stage diverts the transient current through the ground terminal return
path and the second stage clamps the voltage to a safe level without interruption of service.
The 422E/B series is designed to protect data lines from differential (line to line) and common
mode (line to ground) transients. Terminals 1 and 2, 3 and 4 for the 422E and pins 2 and 3, 4,
and 5 for the 422B are designated as line pairs. Each line pair is referenced to ground. A
transient voltage suppressor is connected across each line pair for differential mode protection.
Each line pair is referenced to ground.
This product can also be used on telephone, signal/data lines, security, timing and control
interface circuits. For most applications, the product should be located as close as possible to
the equipment being protected. A low impedance grounding system is important to maintain a
low voltage clamp between the line-to-ground connection.
