Diode Arrays Procurement Notes

Verify the specific suffix HPSA2 against official Infineon documentation to confirm pinout, packaging, and compliance details. Ensure the selected variant matches the required thermal interface and mounting torque specifications for the 34 mm housing. Cross-reference the part number with the latest short form catalog to avoid obsolete or superseded versions.

Diode Arrays Selection Notes

Select this component for applications requiring high surge capability and reliable conduction in medium power circuits. Evaluate the thermal management requirements based on the 0.26 K/W junction-to-case resistance. Confirm that the system operates within the 150 °C maximum junction temperature limit under expected load conditions.

Diode Arrays Part Context

This module belongs to the DD171N product line, which utilizes Advanced Medium Power Technology. The series is designed for industrial applications requiring robust rectification in compact 34 mm housings. The pressure contact design distinguishes it from screw-mounted alternatives by offering superior vibration resistance and lower contact resistance.

Diode Arrays Replacement Considerations

Consult the official Infineon short form catalog for verified substitute part numbers. Ensure any replacement maintains compatibility with the 34 mm footprint and pressure contact mounting style. Verify that alternative devices meet or exceed the 1600 V blocking voltage and 170 A current ratings.
