DD175N36KXPSA1

Overview

The DD175N36KXPSA1 is a single rectifier diode module from Infineon's Power Block series, utilizing 34 mm pressure contact technology. It features a maximum repetitive peak reverse voltage (VRRM) of 3600 V and an average on-state current (IFAVM) of 175 A at 180° electrical conduction. The device has a maximum forward voltage drop (VT0) of 2.05 V at the maximum junction temperature. Key thermal parameters include a junction-to-case thermal resistance (RthJC) of 0.2 K/W and a maximum operating junction temperature (Tvj) of 150 °C. The module supports a non-repetitive surge current (IFSM) of 4300 A for 10 ms.

Feature Summary

• Pressure contact technology ensures high reliability and robust mechanical connection for industrial applications.
• Electrically insulated baseplate provides safety and simplifies mounting without additional insulators.
• High overload capability allows for fuseless design protection in demanding power circuits.

Applications

• Phase control systems in industrial power electronics
• High-voltage DC transmission and conversion equipment
• Industrial motor drives requiring high voltage isolation

Procurement Notes

Verify the exact ordering code against official Infineon documentation, as suffixes like XPSA1 may indicate specific tape-and-reel packaging or compliance variations not always detailed in generic summaries. Confirm RoHS status and lead times directly with authorized distributors, as availability fluctuates. Ensure the procurement channel is authorized to guarantee component authenticity and traceability.

Selection Notes

Select this module when designing circuits requiring 3600 V blocking capability with moderate current ratings up to 175 A. The 34 mm package size suits applications where space is constrained but high power density is needed. Evaluate thermal management requirements based on the 0.2 K/W RthJC value to ensure the heatsink can maintain junction temperatures below 150 °C under continuous load conditions.

Part Context

This component belongs to Infineon's Power Block family, which specializes in high-power semiconductor modules for industrial and traction applications. The 34 mm form factor is a standard industry size for medium-power rectifiers, allowing compatibility with existing heatsink designs and mechanical layouts common in high-voltage power conversion systems.

Replacement Considerations

Direct replacements must match the 3600 V rating, 175 A current capacity, and 34 mm package dimensions. Verify that alternative modules offer comparable forward voltage characteristics and thermal resistance to ensure equivalent performance in the existing circuit design without requiring major layout modifications.
