DESCRIPTION
The SMTPB series are designed for protecting sensitive
telecommunication equipment against lightning and
transient voltages induced by AC power lines.
The devices provide bidirectional protection by crowbar
action.Their characteristic response to transien over-
voltages makes them particularly suited to protect volatge
sensitive telecommunication equipment.
