Diode Arrays Procurement Notes

Verify the specific suffix KHPSA1 against official Infineon documentation to confirm RoHS compliance and lead-free status. Ensure the ordering part number matches the exact datasheet version required for your design. Cross-reference the package dimensions and terminal configuration with the mechanical drawing before procurement to guarantee compatibility with your thermal management solution.

Diode Arrays Selection Notes

Select this component when a single-phase or bridge rectifier application requires 1200 V blocking capability and 171 A continuous current. Evaluate the thermal resistance and junction temperature limits against your system's cooling capacity. Consider the pressure contact mounting requirement for assembly processes compared to soldered alternatives.

Diode Arrays Part Context

This module is part of the DD171N series of high-power diodes manufactured by Infineon Technologies.
