The Infineon T640N14TOF is a high-current, high-voltage thyristor module engineered for demanding power conversion and control applications. Rated at 640A average on-state current and a 1400V repetitive peak off-state voltage (VDRM), this module delivers robust performance in heavy industrial environments. Built to Infineon's proven power module platform, the T640N14TOF offers stable switching characteristics, low thermal resistance, and a rugged isolated base construction — making it a reliable choice for system designers and maintenance teams working with large-scale AC drives, rectifiers, and power regulators.

The T640N14TOF is well suited for AC motor soft starters, controlled rectifiers, industrial heating systems, crane and hoist drives, UPS systems, and grid-tied power conversion equipment. Its high current handling capability and 1400V voltage class make it appropriate for three-phase bridge configurations in medium-voltage industrial infrastructure. Utilities, steel mills, mining operations, marine systems, and heavy manufacturing facilities commonly rely on thyristor modules in this class to maintain continuous production uptime in harsh, high-demand electrical environments.

Quick Reference: T640N14TOF

Key Features of the T640N14TOF:

• 640A average on-state current (IT(AV)) for high-power phase control and rectification circuits
• 1400V repetitive peak off-state voltage (VDRM) providing adequate voltage margin in 690V AC bus applications
• Isolated copper base plate for direct heatsink mounting, minimizing junction-to-case thermal resistance
• Standard power module footprint compatible with established Infineon mounting hardware and gate driver configurations
• Low di/dt and dv/dt sensitivity characteristics supporting reliable triggering in noisy industrial gate drive environments
• Designed for phase-controlled converter topologies including fully controlled and half-controlled three-phase bridge rectifiers

With a current factory lead time of 99 weeks from Infineon, the T640N14TOF is effectively unavailable through standard OEM channels for nearly two years. For maintenance teams facing equipment failures or procurement professionals building safety stock for critical infrastructure, that timeline is simply not acceptable. ATI Accurate Technology specializes in exactly this scenario — stocking hard-to-find, long-lead-time, and legacy Infineon thyristor modules so your operation doesn't wait on a production queue. Whether you need one unit for emergency repair or a larger quantity for a scheduled overhaul, ATI has you covered.
