Below its varistor voltage, it presents very high impedance (near open circuit). When a transient voltage exceeds the varistor voltage, the impedance drops dramatically, clamping the voltage and diverting surge current away from the protected circuit.","pin_description":"<table><tr><th>Terminal<\/th><th>Function<\/th><\/tr><tr><td>Lead 1<\/td><td>AC line connection<\/td><\/tr><tr><td>Lead 2<\/td><td>AC line connection (bidirectional)<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Power supply AC input surge protection<\/li><li>Industrial equipment transient suppression<\/li><li>Home appliance surge protection<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Disc<\/th><th>VAC<\/th><\/tr><tr><td>B72210S2251K101<\/td><td>TDK\/EPCOS<\/td><td>20mm<\/td><td>420VAC<\/td><\/tr><tr><td>V20E420P<\/td><td>Littelfuse<\/td><td>20mm<\/td><td>420VAC<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts\/9705","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/comments?post=9705"}],"version-history":[{"count":0,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts\/9705\/revisions"}],"wp:attachment":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/media?parent=9705"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/categories?post=9705"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/tags?post=9705"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/chip_brand?post=9705"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
