Diode Arrays Procurement Notes

Verify the specific suffix HPSA1 against official Infineon documentation to confirm exact manufacturing lot details and compliance status. Cross-reference the Mouser part number 641-DD89N16K for availability checks. Ensure the procurement channel provides valid traceability documents. Confirm that the component matches the required pressure contact specifications for your assembly process. Validate RoHS compliance data directly from the manufacturer's latest release notes.

Diode Arrays Selection Notes

Select this module when a 1600 V blocking voltage and 89 A continuous current are required in a compact screw-mount form factor. Consider the 0.45 K/W thermal resistance for heatsink design calculations. Compare against the ND89N16K if thyristor functionality is needed instead of pure diode rectification. Evaluate the 2400 A surge rating against potential inrush currents in the target circuit. Ensure the operating temperature range aligns with the system's environmental constraints.

Diode Arrays Part Context

This component belongs to Infineon's Discrete Module family, specifically the Diode Modules subcategory. It is part of the broader Power Block series designed for high-power semiconductor applications. The DD89N16K designation indicates its position within the 20 mm housing lineup for bipolar semiconductors. Related variants include the DD89N14K and DD89N12K, which offer different voltage ratings while maintaining similar current capacities.

Diode Arrays Replacement Considerations

The DD89N16KAHPSA1 is listed as an alias or predecessor variant but is marked as End-of-Life (EOL). The ND89N16KHPSA2 is a related rectifier module with identical electrical ratings but may differ in packaging or lifecycle status. Verify pinout and thermal interface compatibility before substituting any alternative part numbers.
