# AO3400 (Component) ## Description The YFW AO3400 is a 30V N-Channel Enhancement MOSFET designed for low-voltage and high-speed switching applications. It uses advanced trench MOSFET technology to achieve low on-resistance (RDS(on)), fast switching performance, and efficient power handling in a compact SOT-23 package. It is commonly used in load switching, DC-DC converters, battery-powered devices, motor control, LED driving, and PWM switching circuits. Key Features N-Channel Enhancement Mode MOSFET Drain-Source Voltage (VDS): 30V Continuous Drain Current (ID): up to 5.8A Low RDS(on): < 28mΩ @ VGS = 10V < 33mΩ @ VGS = 4.5V < 52mΩ @ VGS = 2.5V Logic-Level Gate Drive Compatible Fast Switching Speed Low Gate Charge Compact SOT-23 Package Suitable for PWM and Load Switch Applications RoHS / Pb-Free Compatible Typical Applications Power switching DC-DC converters Battery management systems Motor and fan control LED drivers Portable electronics Microcontroller-based switching circuits #CommonPartsLibrary #Transistor #FET #Mosfet ## Component Details - **Owner:** lcsc - **Created:** 10/26/2024 - **Last Updated:** 5/28/2026 - **Visibility:** Public - **Manufacturer Name:** YFW(佑风微) - **LCSC Part Number:** C2977509 - **Manufacturer Part Number:** AO3400 - **Drain to Source Voltage:** 30V - **Package or Case Code:** SOT-23-3_L3.0-W1.7-P0.95-LS2.9-BR - **Part Type:** MOSFETs - **Datasheet URL:** https://www.lcsc.com/datasheet/C2977509.pdf?spm=wm.sxq.inf.ggs&lcsc_vid=FlkNBAIDRQULVABfFAVZBgZVFVZYBgZSQ1NeBVIFQlExVlNRTlhdX11QQVFeVzsOAxUeFF5JWBYZEEoKFBINSQcJGk4dAgUUFAk%3D - **Transistor Type:** N-channel MOSFET - **Continuous Drain Current:** 5A (Maximum) at 25°C - **JLCPCB Part Class:** Extended Part - **Used in:** 1008 projects ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
