Wall / Panel / Backboard Mount | Surge suppressors have bolting or mounting holes so that they can be attached to a wall or backboard. | ||
Hard-Wired / Device Mount | Surge suppressors mount on or within the device that is to be protected from surges. | ||
DIN Rail | Surge suppressors mount on a DIN rail. | ||
In-Line / Integrally Attached | Surge suppressors are threaded, or are designed for integral attachment to conduits, cabling, etc. | ||
Plug-in Module | Surge suppressors are modules that plug into an existing system or surge suppression device. | ||
PCB Mount | Surge suppressors are wired or soldered onto printed circuit boards (PCBs). | ||

Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
Technology | |||
Your choices are... | |||
MOV | Metal oxide varistors (MOV) have high energy capabilities, good reliability, and consistent performance. They also have a non-linear clamping curve and fatigue rapidly at higher amperage levels. | ||
Silicon Avalanche Diode | Silicon avalanche diodes have high clamping voltages, but a limited power-handling capacity that is destroyed easily by the power levels encountered in typical power-line surges. Silicon avalanche diodes are used most often in data-line protectors and on circuit boards as static protectors. | ||
Silicon Thyristor Diode | Silicon thyristor diodes are used mainly to protect telecom systems. | ||
Gas Tube | Gas tubes have higher energy capabilities than either MOVs or diodes. They typically consist of two electrodes held at a close distance so that high voltages between the electrodes simply arc through the air to effectively clamp the voltage. Gas tubes are very slow, but can handle very large surges. | ||
Hybrid | Hybrids attempt to incorporate all the major advantages of many of the individual components, while collectively overcoming their individual faults. | ||
Other | Other less commonly used technologies include spark gaps, selenium, and Zener diodes. | ||

Performance

Maximum Surge Current | Maximum surge current is the maximum current allowed for a single impulse waveform with a continuous voltage applied. This value indicates the protection capacity of a particular surge suppressor design, and is used in specifying a product for a given application. A higher-level surge current capacity is required for a high-exposure application where there are very large transients present from lightning. | ||
