FET, MOSFET Arrays datasheet and documents for AO4818

AO4818

FET, MOSFET Arrays Overview

The AO4818 is a dual N-channel enhancement mode field effect transistor manufactured by Alpha & Omega Semiconductor Inc. It utilizes advanced trench technology to achieve low on-resistance and gate charge, making it suitable for load switch and PWM applications. The device features a drain-source voltage of 30V and a continuous drain current of 8A at VGS=10V. The maximum on-resistance is less than 19mΩ at VGS=10V and less than 23mΩ at VGS=4.5V. It operates within a junction temperature range of -55°C to 150°C and is housed in an SOIC-8 package.

FET, MOSFET Arrays Procurement Notes

Verify the specific ordering suffix against official Alpha & Omega Semiconductor documentation to confirm packaging type and environmental compliance status. Ensure that any requested variants match the electrical specifications detailed in the datasheet. Confirm lead times and availability directly with authorized distributors or the manufacturer, as these factors are subject to change based on production schedules and supply chain conditions.

FET, MOSFET Arrays Selection Notes

Select the AO4818 when a dual N-channel MOSFET with a 30V rating and 8A continuous current capability is required. Consider its low on-resistance characteristics for efficient power handling in load switch designs. Evaluate thermal management requirements based on the specified junction-to-ambient resistance values provided in the datasheet for your specific board layout and operating environment.

FET, MOSFET Arrays Part Context

The AO4818 belongs to the AO4818 family of dual N-channel MOSFETs from Alpha & Omega Semiconductor. It shares electrical characteristics with the AO4818L variant, which offers a green product ordering option. Both devices utilize similar trench technology for enhanced performance in compact surface-mount packages like the SOIC-8.

FET, MOSFET Arrays Replacement Considerations

The AO4818L is electrically identical to the AO4818 but offers a different ordering suffix for environmental compliance. Other dual N-channel MOSFETs with similar voltage and current ratings may serve as alternatives if pin compatibility and electrical parameters align with the application requirements.
