The Infineon DD175N32K is a high-voltage, high-current diode module engineered for reliable operation in heavy-duty power electronics applications. Rated at 175A continuous current and a peak repetitive reverse voltage of 3200V, this module is built to handle the thermal and electrical stresses of industrial rectifier stages, regenerative drives, and DC link assemblies. Its robust construction and Infineon's proven semiconductor process make it a preferred choice where long-term reliability and consistent switching performance are non-negotiable requirements.

The DD175N32K sees widespread use across industrial sectors that depend on high-power conversion equipment. Typical applications include AC-DC rectifier bridges in medium-voltage drives, freewheeling circuits in inductive load controllers, traction power supplies, crane and hoist drives, UPS systems, and welding power sources. Its 3200V voltage class makes it especially relevant in applications where line transients and regenerative overvoltages must be absorbed without risk of avalanche breakdown, including mining equipment and heavy process machinery.

Key Features of the DD175N32K:

• 3200V peak repetitive reverse voltage (VRRM) for robust margin in high-line and transient-heavy environments
• 175A average forward current (IFAV) supports continuous operation in high-power rectifier and freewheeling topologies
• Low forward voltage drop minimizes conduction losses and reduces thermal management requirements at full load
• Isolated baseplate construction simplifies heatsink mounting and allows parallel configurations without additional isolation hardware
• Designed for operation up to 125°C junction temperature, ensuring reliable performance across wide ambient and load variation
• Compatible with standard Infineon DD-series footprints, enabling direct drop-in replacement in existing drive and rectifier assemblies

With a factory lead time of 99 weeks, the DD175N32K is one of the most difficult Infineon diode modules to procure through standard OEM or distribution channels. For maintenance engineers dealing with unplanned equipment failures and procurement teams managing MRO inventory or end-of-life system support, a 99-week wait is operationally unacceptable. ATI Accurate Technology specializes in exactly these situations — stocking obsolete, long-lead-time, and allocation-constrained power semiconductors so your line stays running and your projects stay on schedule without compromise.

ATI Accurate Technology is headquartered in Palmetto, Florida and ships the DD175N32K same-day on orders received before 5PM EST. All parts are new OEM condition. Whether you need a single replacement module or a larger quantity for MRO stock or a build project, ATI offers competitive volume pricing.
