The AO4403 is a P-Channel enhancement-mode MOSFET manufactured by Alpha and Omega Semiconductor using advanced trench technology. It is designed for applications requiring low gate charge and operation with gate voltages as low as 2.5V. The device is rated for a drain-source voltage of -30V and a continuous drain current of -6A at 25°C case temperature. On-resistance is specified at multiple gate voltages: 48mΩ maximum at VGS=-10V, 57mΩ at VGS=-4.5V, and 80mΩ at VGS=-2.5V. Typical gate threshold voltage is -0.9V with a range of -0.5V to -1.3V. The device offers low input capacitance of 645pF typical and total gate charge of 7nC at 4.5V. Switching characteristics include typical turn-on delay of 6.5ns and turn-off delay of 41ns. The AO4403 is 100% UIS and Rg tested for reliability. It is housed in an SOIC-8 surface mount package with dimensions 4.9mm x 3.9mm x 1.65mm. The junction temperature range is -55°C to 150°C. Typical applications include load switching, PWM circuits, and power management in portable devices, notebooks, and desktop computers.
