Single FETs, MOSFETs Procurement Notes

Verify the exact suffix against official documentation, as variations such as ATMA1 or TATMA1 may indicate specific tape-and-reel configurations or regional manufacturing sites. Confirm RoHS compliance and halogen-free status via the manufacturer's certificate. Ensure the ordering code matches the required package variant PG-TDSON-8. Cross-reference the datasheet revision date to validate parameter accuracy before integration into design specifications.

Single FETs, MOSFETs Selection Notes

Select this component when low conduction losses are critical in 80 V systems. The 3.7 mΩ Rds(on) balances efficiency with manageable gate charge. Consider the PG-TDSON-8 package for its compact footprint and thermal performance compared to larger packages. Verify that the 100 A current rating aligns with the thermal management strategy of the target application, as this rating is typically specified at case temperature.

Single FETs, MOSFETs Part Context

This part belongs to the OptiMOS 5 family, representing Infineon's silicon-based trench technology for general-purpose power switching. It targets applications requiring high reliability and low loss in the 60-80 V voltage class. The series is widely used in industrial and telecom infrastructure where space constraints and thermal efficiency are paramount design drivers.

Single FETs, MOSFETs Replacement Considerations

Direct substitutes within the same voltage and package class include BSC021N08NS5 (lower Rds(on)) or BSC030N08NS5. Verify pinout compatibility and thermal resistance values before substitution. Ensure the replacement meets the same 175°C junction temperature rating and avalanche testing requirements.
