Diode Arrays Procurement Notes

Verify the specific suffix 'HPSA1' against official Infineon documentation to confirm exact pinout and labeling standards, as variations exist within the DD171N family. Confirm RoHS compliance status and check for any product change notices or obsolescence announcements prior to final design integration, as availability may be limited.

Diode Arrays Selection Notes

Select this component for high-reliability industrial power applications requiring 1600 V blocking capability and moderate current handling. The pressure contact interface offers superior thermal cycling performance compared to soldered alternatives. Ensure the cooling system can maintain the case temperature within limits to support the specified 170 A average current rating without exceeding the 150 °C junction limit.

Diode Arrays Part Context

This module belongs to the DD171N series of bipolar semiconductor rectifiers designed for medium power applications. It shares the same physical footprint and core technology as variants like DD171N18K but differs in voltage rating. The series is characterized by its use of AMPT and pressure contact mounting, targeting durable operation in demanding environments such as motor drives and energy storage systems.

Diode Arrays Replacement Considerations

Direct substitutes with identical specifications are not explicitly confirmed in public data. Consider checking the DD171N18K for higher voltage tolerance if applicable, or consult Infineon's official cross-reference tools for updated equivalents. Verify that any replacement maintains the 34 mm package dimensions and pressure contact interface requirements.
