Single FETs, MOSFETs Procurement Notes

Verify the component authenticity by checking the manufacturer's marking code against official datasheets. Confirm the specific suffix 'ATMA1' matches the required packaging format. Ensure the operating environment stays within the specified junction temperature range of -55°C to 150°C. Cross-reference the PG-TO252-3-1 footprint with your PCB design guidelines before finalizing procurement.

Single FETs, MOSFETs Selection Notes

Select this component when a 500 V rating is required for high-side or low-side switching. The 3.2 A current capacity suits moderate power applications where space constraints favor the TO-252 package. Consider the 190 mΩ on-resistance for efficiency calculations in low-current scenarios. Verify that the 95 nC gate charge aligns with your available gate driver strength.

Single FETs, MOSFETs Part Context

This part belongs to Infineon's CoolMOS family, known for superjunction technology that optimizes the trade-off between on-resistance and breakdown voltage. The SPD series typically targets legacy or specific industrial replacements. The ATMA1 suffix indicates the specific tape-and-reel packaging configuration used for automated assembly processes.

Single FETs, MOSFETs Replacement Considerations

Direct substitutes may include other 500 V N-channel MOSFETs in the TO-252 package with comparable Rds(on) and Id ratings. Verify pinout compatibility and thermal resistance values before substitution. Check if alternative parts offer improved gate charge metrics for higher frequency operation.
