The Infineon TT92N12KOFB4 is a dual thyristor (SCR) power module rated for 92A average on-state current and 1200V repetitive peak off-state voltage. Built into a compact, industry-standard FB4 package, this module delivers reliable phase control and AC switching performance in high-voltage power conversion environments. Its robust silicon construction and optimized gate sensitivity make it well-suited for continuous industrial duty cycles where thermal stability and consistent triggering are non-negotiable. Engineers specifying thyristor modules in this voltage and current class will recognize the TT92N12KOFB4 as a proven Infineon platform component.

The TT92N12KOFB4 sees wide deployment across industrial AC motor drives, soft starters, resistance heating controllers, and DC power supplies requiring front-end rectification with phase-control capability. It is also used in UPS systems, crane and hoist drives, and electrochemical process equipment where precise current regulation at elevated voltages is essential. The module's isolated baseplate construction simplifies thermal management when mounting to a heatsink in multi-module configurations, making it a practical choice for systems integrators building three-phase bridge or anti-parallel converter topologies.

Key Features of the TT92N12KOFB4:

• 92A average on-state current (IT(AV)) with 1200V repetitive peak off-state voltage (VDRM)
• Dual thyristor configuration in a compact FB4 module footprint for simplified board-level or busbar integration
• Isolated copper baseplate for direct heatsink mounting, enabling efficient thermal dissipation in high-power assemblies
• Low gate trigger current (IGT) for compatibility with standard firing circuit designs and PLCs with SCR output cards
• High surge current capability (ITSM) supporting reliable operation under fault and inrush conditions
• Industry-standard terminal layout compatible with Infineon and cross-reference equivalent module mounting arrangements

Infineon's published factory lead time for new production of the TT92N12KOFB4 currently stands at 99 weeks — nearly two years from order placement to delivery. For OEMs managing production schedules, maintenance teams facing unplanned downtime, or procurement professionals building safety stock, waiting on the factory is rarely an option. Parts in this class frequently appear on obsolescence watch lists as manufacturers consolidate product lines, making distributor stock an increasingly critical resource. Sourcing from a stocking distributor with verified inventory and traceable OEM provenance is the only way to eliminate lead-time risk on this component.
