Procurement Notes

Verify the specific suffix FHTL against official documentation to confirm tape and reel packaging specifications. Confirm that the component status remains active for new designs, as related variants may carry different lifecycle statuses. Ensure compatibility with standard SMD assembly processes for the TO-252-3 package. Cross-reference the AEC-Q101 certification details directly with the manufacturer's quality assurance records for automotive projects.

Selection Notes

Select this component when a dual common cathode Schottky diode is required in a DPAK package. The 6 A current rating and 110 V blocking voltage suit medium-power rectification tasks. Consider the low leakage current for high-temperature environments. Verify that the TO-252-3 footprint matches the PCB layout constraints. Compare thermal dissipation requirements against the 150 °C junction limit.
