The AO4842 is a 30V dual N-channel MOSFET from Alpha & Omega Semiconductor, designed using advanced trench technology for low on-resistance and efficient switching. Each MOSFET can handle a continuous drain current of 7.7A at 25°C and 6.5A at 70°C, with a pulsed drain current rating of 64A. The device features a logic-level gate, allowing operation at 4.5V gate drive, with a maximum Rds(on) of 21mΩ at 10V and 30mΩ at 4.5V. Gate charge is 11nC, and input capacitance is 448pF, making it suitable for high-frequency switching applications such as buck converters. The MOSFETs are housed in an 8-SOIC surface-mount package with a compact 3.90mm width. The operating temperature range is -55°C to 150°C, and the device is RoHS3 compliant (unverified). Typical applications include DC-DC converters, power management, and load switching.
