Single FETs, MOSFETs Procurement Notes
Verify the specific ordering suffix 'I' corresponds to the TO-251A IPAK package configuration before procurement. Confirm that the required thermal performance aligns with the specified junction-to-ambient resistance values under your intended board layout conditions. Ensure compatibility with the manufacturer's standard terms and conditions regarding product liability and specifications.
Single FETs, MOSFETs Selection Notes
Select this component when a P-Channel MOSFET with high current handling (-70A) and low on-resistance is required in a TO-251A package. Consider the thermal characteristics and derating curves for high-temperature environments. Verify that the -30V rating meets the system voltage requirements and that the gate drive levels are compatible with the threshold voltage specifications.
Single FETs, MOSFETs Part Context
This part belongs to the AOS AlphaSGT series, which employs advanced trench technology to enhance power efficiency. The AOI423 variant specifically denotes the TO-251A package form factor. It shares electrical characteristics with the AOD423 and AOY423 variants, differing primarily in the physical packaging style provided by the manufacturer.
Single FETs, MOSFETs Replacement Considerations
The AOD423 and AOY423 are electrically identical alternatives offered in different packages (TO-252 and TO-251B respectively). When substituting, ensure the new package fits the PCB footprint and thermal design constraints.
