DESCRIPTION

Dimensions in millimeters

The SMTPB series are designed for protecting sensitive

telecommunication equipment against lightning and

transient voltages induced by AC power lines.

SCHEMATIC DIAGRAM

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.
