When VGS exceeds the threshold (0.8-1.5V), an inversion layer forms in the P-type body region creating a conductive channel between drain and source. The low threshold voltage enables direct drive from 2.5V logic circuits.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>Gate<\/td><td>Gate control input<\/td><\/tr><tr><td>2<\/td><td>Source<\/td><td>Source terminal<\/td><\/tr><tr><td>3<\/td><td>Drain<\/td><td>Drain terminal<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Portable equipment load switching<\/li><li>Battery-powered devices<\/li><li>Low-voltage logic level switching<\/li><li>Small-signal analog switching<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Spec<\/th><th>Package<\/th><\/tr><tr><td>2N7002<\/td><td>onsemi<\/td><td>60V 300mA N-ch MOSFET<\/td><td>SOT-23<\/td><\/tr><tr><td>BSS138<\/td><td>Nexperia<\/td><td>50V 220mA N-ch MOSFET<\/td><td>SOT-23<\/td><\/tr><tr><td>2SK3019EB<\/td><td>Rohm<\/td><td>30V 100mA N-ch MOSFET<\/td><td>SOT-416FL<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/posts\/9843","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/comments?post=9843"}],"version-history":[{"count":0,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/posts\/9843\/revisions"}],"wp:attachment":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/media?parent=9843"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/categories?post=9843"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/tags?post=9843"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=9843"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
