Diode Arrays Procurement Notes

Verify the exact suffix configuration against official Infineon documentation, as ordering codes may vary by region or revision. Confirm RoHS compliance status through the manufacturer's latest environmental declaration. Ensure the procurement channel provides valid traceability for this discontinued or legacy component type. Cross-reference the specific HPSA1 designation with current inventory lists to avoid obsolete stock issues.

Diode Arrays Selection Notes

Select this module when a 1600 V blocking capability and 89 A continuous current are required in a compact form factor. The POW-R-BLOK™ package offers standardized dimensions for easy integration into existing thermal designs. Consider the 1.5 V forward voltage drop for efficiency calculations under high-load conditions. Verify that the screw mounting torque specifications meet the mechanical requirements of the heat sink interface.

Diode Arrays Part Context

This component belongs to the DD89N series of discrete diode modules manufactured by Infineon Technologies. It shares the same physical footprint and basic electrical characteristics as the DD89N16K, with the HPSA1 suffix indicating specific packaging or handling variations. The series is part of Infineon's broader portfolio of bipolar semiconductor devices for power conversion.

Diode Arrays Replacement Considerations

The DD89N16K is a confirmed substitute part number with identical electrical ratings and pinout compatibility. Other variants in the DD89N family, such as those with different voltage ratings (e.g., DD89N14K), require careful evaluation of reverse voltage margins before substitution.
