TVS Diodes are a semiconductor device designed to limit or stop surges in a specific voltage level. The items in this family are designed using diodes (a component that conducts in just one direction). TVS is an acronym for Transient Voltage Suppression (Suppressor). The types are steering (rail to rail) or Zener with the characteristics of unidirectional channels, bidirectional channels, voltage – reverse standoff, voltage – breakdown, voltage – clamping, current – peak pulse, power – peak pulse, and power line protection.
