The AO4422 is a N-channel enhancement mode field effect transistor from Alpha & Omega Semiconductor, Ltd. Its maximum drain-source voltage is 30V, and its maximum drain-source current is 11A. Its on-resistance is less than 15mΩ (VGS = 10V) and less than 24mΩ (VGS = 4.5V).
The A04422 is an N‑Channel Enhancement Mode Field Effect Transistor that uses advanced trench technology to deliver low gate charge and high current capability. It is intended for use as a load switch or in power‑voltage‑modulation applications, with source leads that can be Kelvin‑connected to reduce source inductance.
Key specifications include a maximum drain‑source voltage of 30 V, gate‑source voltage rating of +20 V, continuous drain current of 11 A at 25 °C, and a pulsed drain current rating of 50 A. Thermal data show a maximum junction‑to‑ambient temperature of 40 °C and a power dissipation of 2.1 W. Electrical parameters such as input capacitance (Ciss = 1040 pF) and on‑resistance are also provided.
