The AO4406A is a 30V N-Channel MOSFET manufactured by Alpha & Omega Semiconductor. It uses advanced trench technology to provide low on-resistance (RDS(ON) < 11.5mΩ at VGS = 10V, < 15.5mΩ at VGS = 4.5V) and low gate charge, making it suitable for high-side switching in applications like switch-mode power supplies (SMPS) and notebook CPU core power management. Key specifications include:

• Drain-Source Voltage (VDS): 30V
• Continuous Drain Current (ID): 13A (at VGS = 10V, Ta = 25°C)
• Maximum Power Dissipation: 3.1W
• Gate-Source Voltage (VGS): ±20V
• Gate Threshold Voltage (VGS(th)): 2.5V max
• Total Gate Charge (Qg): 5nC
• Package: SO-8 (SOP-8)
• Operating Temperature: -55°C to 150°C
