With a maximum drain-source voltage of 30V and a continuous drain current of up to 5.7A, it offers excellent performance for its size. The device features a low on-resistance (R\u003csub\u003eDS(on)\u003c\/sub\u003e) — typically around 45mΩ at V\u003csub\u003eGS\u003c\/sub\u003e = 4.5V, allowing for minimal conduction losses and improved thermal performance in compact circuits.\u003cbr\u003e\u003cbr\u003eThanks to its fast switching capabilities and low gate charge, the AO3403 is well-suited for use in DC-DC converters, load switches, motor drivers, and power management systems. Its logic-level gate drive compatibility makes it easy to interface with microcontrollers and low-voltage logic circuits. The SOT-23 package not only supports space-constrained PCB designs but also provides sufficient thermal and electrical performance for many general-purpose switching tasks in consumer and industrial electronics.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e\u003cbr\u003eProduct Images are shown for illustrative purposes only and may differ from the actual product.\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eTechnical Details\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eType: N-Channel Enhancement Mode MOSFET\u003c\/li\u003e\n\u003cli\u003ePackage: SOT-23 (Surface Mount Device)\u003c\/li\u003e\n\u003cli\u003eDrain-Source Voltage (V\u003csub\u003eDS\u003c\/sub\u003e): 30V\u003c\/li\u003e\n\u003cli\u003eContinuous Drain Current (I\u003csub\u003eD\u003c\/sub\u003e): 5.8A @ V\u003csub\u003eGS\u003c\/sub\u003e = 10V, T\u003csub\u003eA\u003c\/sub\u003e = 25°C\u003c\/li\u003e\n\u003cli\u003eR\u003csub\u003eDS(on)\u003c\/sub\u003e: 22 mΩ @ V\u003csub\u003eGS\u003c\/sub\u003e = 10V, I\u003csub\u003eD\u003c\/sub\u003e = 4.5A\u003c\/li\u003e\n\u003cli\u003eR\u003csub\u003eDS(on)\u003c\/sub\u003e: 30 mΩ @ V\u003csub\u003eGS\u003c\/sub\u003e = 4.5V, I\u003csub\u003eD\u003c\/sub\u003e = 3.5A\u003c\/li\u003e\n\u003cli\u003eGate Threshold Voltage (V\u003csub\u003eGS(th)\u003c\/sub\u003e): 1.0V to 2.5V\u003c\/li\u003e\n\u003cli\u003eGate-Source Voltage (V\u003csub\u003eGS\u003c\/sub\u003e): ±12V (max)\u003c\/li\u003e\n\u003cli\u003eTotal Gate Charge (Q\u003csub\u003eg\u003c\/sub\u003e): ~10nC @ V\u003csub\u003eGS\u003c\/sub\u003e = 4.5V\u003c\/li\u003e\n\u003cli\u003eInput Capacitance (C\u003csub\u003eiss\u003c\/sub\u003e): ~500pF\u003c\/li\u003e\n\u003cli\u003ePower Dissipation (P\u003csub\u003eD\u003c\/sub\u003e): ~1.4W @ T\u003csub\u003eA\u003c\/sub\u003e = 25°C\u003c\/li\u003e\n\u003cli\u003eOperating Junction Temperature (T\u003csub\u003eJ\u003c\/sub\u003e): -55°C to +150°C\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eFeatures\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eLow R\u003csub\u003eDS(on)\u003c\/sub\u003e for high efficiency and low power loss\u003c\/li\u003e\n\u003cli\u003eFast switching speed\u003c\/li\u003e\n\u003cli\u003eLow gate drive voltage (as low as 2.5V)\u003c\/li\u003e\n\u003cli\u003eCompact SOT-23 surface-mount package\u003c\/li\u003e\n\u003cli\u003eRoHS compliant and halogen-free\u003c\/li\u003e\n\u003cli\u003eIdeal for low-voltage applications\u003c\/li\u003e\n\u003cli\u003eHigh-speed pulsed switching capability\u003c\/li\u003e\n\u003cli\u003eEnhanced ESD protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch2 class=\"sing--sub-heading\"\u003e\u003cspan style=\"font-size: 18.72px;\"\u003eApplications :\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePower Management in Portable Devices\u003c\/li\u003e\n\u003cli\u003eLoad Switching for Low-Voltage Circuits\u003c\/li\u003e\n\u003cli\u003eBattery-Powered Equipment\u003c\/li\u003e\n\u003cli\u003eDC-DC Converter Circuits\u003c\/li\u003e\n\u003cli\u003eReverse Polarity Protection\u003c\/li\u003e\n\u003cli\u003eMotor Control for Small DC Motors\u003c\/li\u003e\n\u003cli\u003eLow-Side and High-Side Switching\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePhysical Attributes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eWeight (g): 2\u003c\/li\u003e\n\u003cli\u003eLength: 2.92mm\u003c\/li\u003e\n\u003cli\u003eWidth: 1.3mm\u003c\/li\u003e\n\u003cli\u003eHeight: 1.1mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePackage Includes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds ls-n\"\u003e\n\u003cli\u003e1 x AO3403 SMD Low Voltage N-Channel MOSFET SOT-23 Package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"KitsGuru","offers":[{"title":"Default Title","offer_id":47166121246972,"sku":"INTEG160","price":6.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/AO3403SMDLowVoltageN-ChannelMOSFETSOT-23Package-1.jpg?v=1747225253","url":"https:\/\/kitsguru.com\/fr\/products\/ao3403-smd-low-voltage-n-channel-mosfet-sot-23-package","provider":"KitsGuru","version":"1.0","type":"link"}
