This is one of the most widely used SOT-23 MOSFETs for low-voltage load switching in Li-ion battery-powered devices, DC-DC converters, and motor drives. The low threshold voltage (0.65V typical) allows direct drive from 2.5V logic.","working_principle":"The SI2302DS-T1-GE3 uses Vishay's TrenchFET technology with a vertical trench-gate structure that provides high channel density. This achieves 65mOhm RDS(ON) in the compact SOT-23 package, significantly better than planar MOSFET alternatives. The 20V rating covers single-cell Li-ion (3.0-4.2V) and 5V USB power applications with adequate voltage margin. The low threshold (0.65V) enables operation from low-voltage MCU GPIO.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>G<\/td><td>Input<\/td><td>Gate<\/td><\/tr><tr><td>2<\/td><td>S<\/td><td>Power<\/td><td>Source<\/td><\/tr><tr><td>3<\/td><td>D<\/td><td>Output<\/td><td>Drain<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Li-ion battery load disconnect switch<\/li><li>Single-cell DC-DC buck converter low-side<\/li><li>Toy and drone motor H-bridge element<\/li><li>LED indicator string driver<\/li><li>5V USB power load switch<\/li><\/ul>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>Vishay<\/td><td>SI2304DS-T1-GE3<\/td><td>SOT-23<\/td><td>30V version<\/td><\/tr><tr><td>Infineon<\/td><td>BSB008NE2LX<\/td><td>SOT-23<\/td><td>20V 8.5mOhm<\/td><\/tr><tr><td>Diodes Inc<\/td><td>DMN2075U-7<\/td><td>SOT-23<\/td><td>20V 75mOhm<\/td><\/tr><tr><td>onsemi<\/td><td>NTS4001NT1G<\/td><td>SOT-23<\/td><td>20V 55mOhm<\/td><\/tr><tr><td>NXP<\/td><td>PMV65XP<\/td><td>SOT-23<\/td><td>20V 60mOhm<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/9976","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=9976"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/9976\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media?parent=9976"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/categories?post=9976"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/tags?post=9976"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=9976"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
