# AO3422 b38f ## Description The AO3422 from Alpha & Omega Semiconductor is a high-performance, N-Channel Enhancement Mode Field Effect Transistor (FET) that leverages advanced trench technology to achieve outstanding RDS(ON) and low gate charge. Designed for efficient power conversion and load switching applications, this component operates effectively across a wide gate drive range of 2.5V to 12V. The AO3422 is characterized by a drain-source voltage (VDS) of 55V and a continuous drain current (ID) of 2.1A at a gate-source voltage (VGS) of 4.5V. Its RDS(ON) is impressively low, coming in at less than 160mΩ at VGS of 4.5V, making it suitable for a variety of power management tasks. The device is encapsulated in a compact SOT23 package, offering a robust solution for space-constrained applications. Additional features include a maximum junction temperature of 150°C, high forward transconductance, and fast switching characteristics that support efficient and reliable operation in high-performance circuit designs. ## Project Details - **Owner:** an-example-org - **Created:** 6/20/2024 - **Last Updated:** 6/20/2024 - **Visibility:** Public - **Q G 3 VGS:** 1.77nC - **Continuous Drain Current:** 2.1 - **Current Rating:** 2.1A - **Datasheet URL:** https://cdn2.flux.ai/copilot-datasheets/pdf-upload-45ff485d6bbe3b8cf1e94fd9814e9aa7b0631a0315b3388059f187c2516ee94c/45ff485d6bbe3b8cf1e94fd9814e9aa7b0631a0315b3388059f187c2516ee94c.pdf?GoogleAccessId=graviton-mvp%40appspot.gserviceaccount.com&Expires=4872513984&Signature=Yj71E7Xxp%2F6b%2FSYu%2Fojx54XCV0R6GBVdmgr%2BhH5A1KtDfouB90E3qI1ytmm%2BgswCFUawWGgqiVvCVP1bgu4DdCzcGn2jR6ibyCpteydlcjTsW663gTEwVKryn3hG3D5vOOl14cYzU0NW8vuNEVOyXdDEVOvOnbmwGgm6YWv5V0nHBGouDOVefJsVGQp2YqNK1KL9gY1rbU9ItWWxfmghkvQX1KzIBYqu5F9euf9OdkIa%2B7SpfPtEWluXGsZdJcQm4%2F5UNtQjt1EkHCRn8q3DEYxbHAKkPENGn8i0hTPJYEcPAqkm1bez47bILYEGbAlgTjztYx52xH5k1gDbmJbCEw%3D%3D - **Drain To Source Voltage:** 55V - **R DS ON 6 5 VGS:** 121.87mΩ - **Gate Charge Max:** 3.3nC - **Input Capacitance Max:** 300pF - **Manufacturer Part Number:** AO3422 - **Operating Temperature Range:** -55 to 150 - **Package or Case Code:** SOT23 - **Part Type:** FET - **Power Dissipation:** 1.25W - **Rds On Max:** 160mΩ - **Vgs Max:** +12V - **Voltage Rating:** 55V *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/an-example-org/ao3422-b38f~8g](https://www.flux.ai/an-example-org/ao3422-b38f~8g).* --- *Generated from [https://www.flux.ai/an-example-org/ao3422-b38f~8g](https://www.flux.ai/an-example-org/ao3422-b38f~8g)*
