A fuse is a device designed to stop current flow when it exceeds a certain limit (overcurrent protection). The devices works by creating an opening in a material situated between two end terminals. The material will melt (blow) from an increase in heat generated by the device as the current flow changes. The amount of time it takes the device to blow is often defined as fast or slow-blow.
TVS - Diodes
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.
TVS - Varistors, MOVs
Transient voltage suppression (TVS) products based on Metal Oxide Varistor (MOV) technology are used to protect electrical and electronic devices against excess voltage hazards, such as may be caused by lighting induced transients, static electricity, or similar hazards. Their relatively high parasitic capacitance limits their application to low frequency circuits such as AC utility power inputs, in which application they excel due to their comparably high power dissipation capability and clamping behavior, which allows continued operation of protected devices without need of a reset process following a protection event, as is common with crowbar protection mechanisms.
Thermal Cutoffs (Thermal Fuses and Breakers)
Thermal Cutoffs (Thermal Fuses) are devices designed to keep components safe in situations when an excessive temperature occurs. When the rated functioning temperature of the thermal cutoff is exceeded, the device will fail open in the electrical circuit, breaking the flow of current.
