Procurement Notes

Verify the specific package variant required, as the datasheet covers AOD482 and AOI482 which share electrical characteristics but may differ in physical packaging such as TO-252 or IPAK. Confirm that the component meets consumer market qualification standards, as critical life support applications are not authorized. Ensure compatibility with the intended thermal management design given the specified thermal resistance values.

Selection Notes

Select this component for applications requiring high current handling up to 32A and low conduction losses below 37mΩ. Consider the 175°C maximum junction temperature for high-temperature environments. Evaluate the gate charge requirements against the driver capability, noting the 26nC to 44nC range. Ensure the PCB layout supports the thermal dissipation needs defined by the junction-to-ambient resistance.
