The EUPEC 120632-DT46N is a thyristor/diode combination power module engineered for high-reliability operation in industrial AC/DC conversion, drive systems, and controlled rectifier circuits. EUPEC, a recognized leader in high-power semiconductor technology now operating under Infineon Technologies, built this module to deliver consistent gate-controlled switching performance alongside low forward-voltage diode conduction in a compact, thermally efficient package. As a legacy EUPEC component, the 120632-DT46N is no longer in routine production, making in-stock availability through specialized distributors critical for facilities dependent on this design.

The 120632-DT46N is well suited for applications including DC motor drives, soft-start systems, regenerative braking circuits, UPS rectifier stages, and industrial power supplies where a controlled thyristor and a freewheeling or blocking diode are integrated in a single housing. Its module construction simplifies PCB and busbar layouts, reduces interconnect inductance, and improves thermal management versus discrete component assemblies. Industries including steel, paper, mining, marine propulsion, and oil and gas infrastructure commonly rely on EUPEC thyristor/diode modules of this platform in legacy drive cabinets and rectifier panels.

Key Features of the 120632-DT46N:

• Thyristor/diode co-packaged module configuration reduces external component count and simplifies drive topology design
• EUPEC-grade silicon construction provides stable gate trigger characteristics and low on-state voltage drop for efficient power conversion
• Isolated baseplate design enables direct heatsink mounting with standard thermal interface materials, supporting robust thermal dissipation in continuous-duty applications
• Compact module footprint compatible with existing drive cabinet form factors, facilitating like-for-like replacement without mechanical redesign
• Suitable for both phase-controlled rectifier and inverter-assist circuit topologies commonly found in legacy industrial drive systems
• New OEM condition ensures original manufacturer specifications are fully met, critical for safety-rated and process-critical installations

With a current factory lead time of 99 weeks, procuring the 120632-DT46N through standard channels is not a viable option for facilities facing unplanned downtime or scheduled maintenance windows. EUPEC legacy modules across this platform have not seen active replenishment, and the supply window for new OEM stock continues to tighten. ATI Accurate Technology maintains inventory of hard-to-find and long-lead-time EUPEC components specifically to serve maintenance and procurement teams who cannot wait nearly two years for factory delivery. Securing stock now is strongly advisable for any operation running equipment dependent on this module.

ATI Accurate Technology is located in Palmetto, Florida and specializes in IGBTs, thyristors, diodes, and rectifier modules — including obsolete and long-lead-time parts.
