GPZ1275
Description
The GPZ1275 is a high power transient voltage suppressor (TVS) designed to provide protection against long duration
switching transient threats. This heavy duty device is constructed using hermetically sealed TVS subassemblies and is
suited for DC applications that include heavy duty motors, generators, or where DC power is being switched on and off
at frequent intervals.
