The low 0.65-1.2V threshold allows direct drive from 2.5V logic. The compact footprint and low cost make it popular for general-purpose switching in battery-powered and low-voltage applications.","working_principle":"The FDV303N is a voltage-controlled switch. When VGS exceeds the threshold (0.65-1.2V), the N-channel conducts from drain to source. Enhancement mode means normally off at VGS=0V. Low threshold enables direct interface with 2.5V or 3.3V logic.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>G<\/td><td>Gate<\/td><\/tr><tr><td>2<\/td><td>S<\/td><td>Source<\/td><\/tr><tr><td>3<\/td><td>D<\/td><td>Drain<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Logic-level load switching<\/li><li>Battery-powered power control<\/li><li>Level shifting and signal gating<\/li><li>LED switching circuits<\/li><\/ul>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Notes<\/th><\/tr><tr><td>onsemi<\/td><td>2N7002LT1G<\/td><td>Industry standard N-MOSFET<\/td><\/tr><tr><td>Nexperia<\/td><td>BSS138P<\/td><td>Logic-level N-MOSFET<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/5140","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/comments?post=5140"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/5140\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media?parent=5140"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/categories?post=5140"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/tags?post=5140"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=5140"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
