The logic-level gate drive (fully enhanced at 4.5V) allows direct interface with 3.3V\/5V MCU GPIOs without gate driver circuitry. The 16 nC total gate charge enables efficient switching at moderate frequencies. The PowerPAK 1212-8S package provides excellent thermal performance with its exposed drain pad, supporting 34 W power dissipation. This device is ideal for battery-powered load switching and synchronous rectification in portable electronics.","working_principle":"The SIRA18ADP-T1-GE3 uses Vishay TrenchFET technology where vertical trenches are etched into the silicon and filled with gate oxide and polysilicon gate material. This trench gate structure provides high channel density and eliminates the JFET region present in planar MOSFETs, resulting in significantly lower RDS(on) per unit area. When VGS exceeds the threshold (0.65-1.45V), an inversion layer forms along the trench sidewalls, creating conduction channels between the source and drain. The low 9.3 mOhm RDS(on) at VGS=4.5V is achieved through advanced cell design and optimized trench geometry. The logic-level gate means the device is fully enhanced at 4.5V VGS, making it compatible with 3.3V\/5V logic without additional gate drive voltage. The low Qg (16 nC) minimizes gate drive power loss at switching frequencies up to several hundred kHz.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>Source<\/td><td>Power<\/td><td>Source terminal<\/td><\/tr><tr><td>2<\/td><td>Gate<\/td><td>Input<\/td><td>Gate drive input<\/td><\/tr><tr><td>3<\/td><td>Source<\/td><td>Power<\/td><td>Source terminal<\/td><\/tr><tr><td>4-8<\/td><td>Drain<\/td><td>Power<\/td><td>Drain terminals<\/td><\/tr><tr><td>Pad<\/td><td>Drain<\/td><td>Power<\/td><td>Exposed thermal pad (drain)<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Portable device battery load switch with 3.3V MCU control<\/li><li>Synchronous buck converter low-side MOSFET<\/li><li>Motor drive H-bridge low-side leg<\/li><li>Hot-swap and inrush current limiting in server blades<\/li><li>USB PD port power routing and protection<\/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>SIRA14DP-T1-GE3<\/td><td>PowerPAK 1212-8<\/td><td>20V, lower RDS(on)<\/td><\/tr><tr><td>Infineon<\/td><td>BSZ097N06LS5ATMA1<\/td><td>PQFN-8<\/td><td>60V, 9.7mOhm, higher voltage<\/td><\/tr><tr><td>onsemi<\/td><td>NTMFS4C05N<\/td><td>PQFN-5x6<\/td><td>30V, 5.4mOhm, larger package<\/td><\/tr><tr><td>Texas Instruments<\/td><td>CSD17579Q5A<\/td><td>SON-5<\/td><td>30V, 9.6mOhm, power block<\/td><\/tr><tr><td>AOS<\/td><td>AON6260E<\/td><td>DFN-8<\/td><td>30V, 8.5mOhm, similar class<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/6782","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=6782"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/6782\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media?parent=6782"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/categories?post=6782"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/tags?post=6782"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=6782"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
