AO4498

Overview

The AO4498 is a 30V N-Channel Enhancement Mode Field Effect Transistor manufactured by Alpha & Omega Semiconductor. It utilizes advanced trench MOSFET technology to achieve extremely low on-resistance, making it suitable for load switching and battery protection applications. The device features a maximum drain-source voltage of 30V and a continuous drain current of 18A at VGS=10V. Key electrical parameters include an RDS(ON) of less than 5.5mΩ at VGS=10V and less than 7.5mΩ at VGS=4.5V. It is packaged in an SOIC-8 surface-mount package with a junction temperature range of -55°C to 150°C.

Procurement Notes

Verify the specific datasheet revision and manufacturing date code upon procurement. Ensure that the component meets RoHS compliance requirements if applicable to your design. Confirm thermal management strategies align with the specified junction-to-ambient thermal resistance values under your actual board layout conditions. Cross-reference the part number with official Alpha & Omega Semiconductor documentation to avoid counterfeit components.

Selection Notes

Select the AO4498 when designing circuits requiring a 30V N-Channel MOSFET with low on-resistance for efficient power handling. Consider its 18A continuous drain current capability and SOIC-8 packaging for space-constrained applications. Evaluate the thermal performance based on your specific PCB copper area and airflow conditions, as the junction-to-ambient resistance is highly dependent on board design.

Part Context

The AO4498 belongs to the family of N-Channel Enhancement Mode MOSFETs produced by Alpha & Omega Semiconductor. These devices are designed for general-purpose power switching applications where low conduction losses and fast switching speeds are critical. The SOIC-8 package offers a compact footprint suitable for surface-mount assembly processes commonly used in modern electronic manufacturing.
