Single FETs, MOSFETs Procurement Notes

Verify the specific package variant required, as the datasheet covers AOD518 and AOI518 which share electrical specifications but may differ in physical packaging such as TO-251B or DPAK. Confirm RoHS and Halogen-Free compliance status matches project requirements. Ensure the component is suitable for consumer market applications, as critical life support uses are not authorized by the manufacturer.

Single FETs, MOSFETs Selection Notes

Select this component when a 30V N-Channel MOSFET with high current handling up to 46A is needed. The low on-resistance at 4.5V makes it suitable for logic-level driving applications. Consider the thermal resistance values for heat dissipation planning in computing and industrial power supply designs. Verify that the operating temperature range meets the environmental constraints of the target system.

Single FETs, MOSFETs Part Context
