S20K275 Description

Short technical summary and product information.

The EPCOS S20K275 is a leaded metal-oxide varistor (MOV) designed for transient voltage suppression. It features a round varistor element with epoxy resin coating, flame-retardant to UL 94 V-0, and tinned copper wire terminals.

Key electrical specifications include a maximum applied AC voltage of 275V and a maximum applied DC voltage of 350V. The nominal varistor voltage is 430V, with a clamping voltage of 710V at 100A. This varistor can handle a peak current of 6.5kA and a transient energy of 140J, with a response time of 15ns.

This component is suitable for through-hole mounting. The SuperioR Series designation suggests high-energy capabilities and very high surge current ratings.

Environmental compliance includes RoHS3 compliance, MSL 1 Unlimited, and REACH unaffected status, though these are currently of low confidence and require verification.
