P-channel MOSFETs are used for high-side switching: the source connects to the positive supply, and the drain connects to the load. When VGS is more negative than the threshold (-0.6 to -1.2V), the channel conducts. To fully enhance the MOSFET (minimum RDS(on)), VGS must be -4.5V or lower. For a 5V system, the gate is pulled to GND (VGS = -5V) to turn on, and to 5V (VGS = 0V) to turn off. The 60mOhm RDS(on) produces 0.78W at 3.6A, exceeding the SOT-23-3 package dissipation limit (0.5W at 25C). In practice, continuous current is limited to 2-3A with adequate PCB copper for heatsinking. The gate charge is only 7nC at VGS=-4.5V, allowing fast switching with minimal drive power. The device includes an internal gate-source ESD protection zener (8V clamp). The SOT-23-3 pinout follows the standard MOSFET convention: pin 1=G, pin 2=S, pin 3=D. The -NT1G suffix specifies SOT-23-3, lead-free, tape-and-reel (3000 pcs). Applications include: load switches (power gating), battery protection circuits, and reverse polarity protection in 3.3-5V systems.","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 (VGS threshold -0.6 to -1.2V, max +\/-8V)<\/td><\/tr><tr><td>2<\/td><td>S<\/td><td>Power<\/td><td>Source (connects to positive rail for high-side P-ch switching)<\/td><\/tr><tr><td>3<\/td><td>D<\/td><td>Power<\/td><td>Drain (-30V VDSS, connects to load, 60mOhm RDS(on) at VGS=-4.5V)<\/td><\/tr><\/table>","application_scenarios":"<li>Industrial control<\/li><li>Consumer electronics<\/li><li>Communication equipment<\/li><li>Automotive electronics<\/li>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>onsemi<\/td><td>NTR4503NT1G<\/td><td>SOT-23-3<\/td><td>Same device, onsemi brand<\/td><\/tr><tr><td>Diodes Inc<\/td><td>DMP3098L-7<\/td><td>SOT-23-3<\/td><td>P-ch -30V -2.4A, 65mOhm, Diodes Inc<\/td><\/tr><tr><td>Vishay<\/td><td>SI2323DS-T1-E3<\/td><td>SOT-23-3<\/td><td>P-ch -20V -3A, 40mOhm, Vishay<\/td><\/tr><tr><td>Infineon<\/td><td>BSS84P7H6327XTSA1<\/td><td>SOT-23-3<\/td><td>P-ch -60V -0.13A, Infineon<\/td><\/tr><tr><td>Toshiba<\/td><td>SSM3J334R<\/td><td>SOT-23-3<\/td><td>P-ch -30V -3A, 28mOhm, Toshiba<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/5587","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/comments?post=5587"}],"version-history":[{"count":1,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/5587\/revisions"}],"predecessor-version":[{"id":6171,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/5587\/revisions\/6171"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=5587"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=5587"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=5587"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=5587"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
