Single FETs, MOSFETs Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm lead-free status and tape-and-reel packaging specifications. Ensure the component matches the required D2PAK footprint dimensions and thermal characteristics for the target PCB layout. Cross-reference the part number with official Infineon databases to validate current production status and availability.

Single FETs, MOSFETs Selection Notes

Select this component when low on-resistance is critical for efficiency in 55 V DC-DC or motor control designs. The logic-level threshold allows for efficient driving from standard 3.3 V or 5 V logic sources without additional gate drivers. Consider the D2PAK package's thermal dissipation limits relative to the expected continuous current load and ambient operating conditions.

Single FETs, MOSFETs Part Context
