The Infineon 192697-TT104N is a TT104N series thyristor (SCR) module engineered for high-current, high-reliability operation in industrial power electronics. Built to Infineon's established TT-series platform, this module integrates thyristor elements in a ruggedized package suited for continuous duty in harsh electrical environments. Its robust construction supports phase control, AC power regulation, and rectification duties where precise gate triggering and low on-state losses are essential. Engineers specifying this part can expect stable thermal performance, consistent gate sensitivity, and the proven longevity Infineon's thyristor portfolio is known for in the field.

The 192697-TT104N is well suited for industrial drives, soft starters, DC motor controllers, induction heating systems, and UPS infrastructure where controlled rectification and AC switching are core functions. It is also deployed in welding equipment, crane and hoist drives, steel mill auxiliary systems, and other heavy industrial machinery demanding dependable thyristor switching across wide load ranges. Its module format simplifies thermal management and bus-bar integration, making it a practical choice for OEM power stack designs as well as field-replacement maintenance scenarios where board-level swaps need to be fast and reliable.

Key Features of the 192697-TT104N:

• TT104N thyristor module platform featuring integrated SCR elements optimized for phase-control and line-commutated rectifier topologies
• High repetitive peak off-state voltage (VDRM) rating supporting direct connection to medium-voltage industrial supply lines
• Rated continuous on-state current (IT(AV)) in the 100A-class range, appropriate for high-duty-cycle industrial load profiles
• Low on-state voltage drop (VT) reduces conduction losses and thermal stress across extended operating cycles
• Gate trigger specifications designed for direct interface with standard industrial thyristor firing boards and pulse transformers
• Isolated baseplate construction enables straightforward mounting to heatsink assemblies without additional electrical isolation hardware

With a verified factory lead time of 99 weeks on new production orders, the 192697-TT104N represents exactly the type of long-lead-time, hard-to-source component that can stall capital projects and extend unplanned equipment downtime. Whether you are maintaining legacy industrial drives, building replacement power stacks for aging machinery, or protecting MRO inventory against future outages, waiting nearly two years for factory fulfillment is not a viable option. ATI Accurate Technology maintains stock of difficult-to-source Infineon thyristor modules precisely to bridge this gap, providing immediate access to parts that OEM supply chains simply cannot deliver on short notice.

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