Single FETs, MOSFETs Procurement Notes

Verify the specific ordering suffix ATMA1 to confirm tape-and-reel packaging and ensure it matches the required reel quantity. Confirm that the component meets the necessary AEC-Q101 reliability requirements for your specific automotive application environment. Cross-reference the datasheet revision date to ensure you are using the latest technical specifications and safety warnings provided by Infineon.

Single FETs, MOSFETs Selection Notes

Select this component when a 40 V N-channel MOSFET with high current handling is required in a D2PAK package. Ensure the gate drive voltage can reach at least 10 V to achieve the specified low on-resistance. Verify that the PCB layout provides sufficient copper area for the drain connection to manage the thermal resistance effectively under your expected operating conditions.

Single FETs, MOSFETs Part Context

This part belongs to Infineon's OptiMOS-T2 family, designed for low-side switching applications. It is distinct from leaded versions like IPP120N04S4-02 and other SMD variants such as IPI120N04S4-02 due to its specific PG-TO263-3 package configuration. The 'ATMA1' suffix indicates the specific packaging and marking details for mass production supply chains.

Single FETs, MOSFETs Replacement Considerations

Direct pin-compatible replacements within the same package and voltage class should be evaluated based on Rds(on) and Qg values. Check if alternative OptiMOS generations offer improved figures of merit while maintaining the 40 V rating and D2PAK footprint.
