AO4484

Overview

The AO4484 is a 40V N-Channel MOSFET manufactured by Alpha & Omega Semiconductor. It utilizes advanced trench technology to achieve an on-resistance of less than 10mΩ at VGS=10V and less than 12mΩ at VGS=4.5V. The device supports a continuous drain current of 10A and a pulsed drain current of 120A. It features low gate charge, with Qg values of 37nC at 10V and 18nC at 4.5V. The component is housed in an SOIC-8 package and is rated for junction temperatures ranging from -55°C to 150°C.

Feature Summary

Advanced trench technology provides excellent on-resistance characteristics combined with low gate charge for efficient switching performance.
Fully characterized for unclamped inductive switching (UIS) and gate resistance testing to ensure robust operation under transient conditions.

Applications

Power conversion circuits
PWM control applications
General purpose load switching

Procurement Notes

Verify the specific datasheet revision and manufacturing lot details upon procurement. Confirm that the received components match the SOIC-8 package outline and electrical parameters defined in the official Alpha & Omega Semiconductor documentation. Ensure compliance with the consumer market qualification status specified in the product literature.

Selection Notes

Select this component for designs requiring a 40V N-Channel MOSFET with high current handling capabilities in a surface-mount configuration. Consider the thermal impedance characteristics when designing heat dissipation strategies, as the junction-to-ambient rating depends on the specific PCB copper area and airflow conditions utilized in the final assembly.
