FET, MOSFET Arrays Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Infineon Technologies to ensure authenticity. Check RoHS compliance status via official datasheets. Validate the SO-8 package dimensions against your PCB footprint requirements before finalizing procurement decisions.

FET, MOSFET Arrays Selection Notes

Select this component for low-voltage, high-current applications requiring dual N-channel isolation. The 20 V rating suits 3.3 V or 5 V systems. Compare Rds(on) and Qg values against alternatives for efficiency optimization. Ensure the SO-8 package fits the available board space and thermal constraints of the design.

FET, MOSFET Arrays Part Context

This part belongs to Infineon's HEXFET family, known for planar trench technology. The IRF7311 variant specifically offers dual N-channel functionality in an 8-pin SOIC package. It complements other HEXFET devices like the IRF7309 and IRF7319, which offer similar configurations but with different voltage or current ratings.

FET, MOSFET Arrays Replacement Considerations

The IRF7309TRPBF serves as a functional substitute, offering dual N/P-channel configuration with comparable 30 V ratings. Verify pinout compatibility and electrical parameters such as Rds(on) and Id before substitution.
