The Infineon TT92N12KOF is a thyristor (SCR) module rated for 92A average on-state current and 1200V repetitive peak off-state voltage. Housed in a compact, industry-standard power module package, it integrates two thyristors in a configuration optimized for phase-control and AC power switching circuits. The device features an isolated baseplate for straightforward heatsink mounting, low thermal resistance for efficient heat dissipation, and gate characteristics suited to standard trigger circuits. It is engineered for continuous industrial duty where reliability, consistent triggering, and long service life are non-negotiable requirements.

The TT92N12KOF is widely deployed across heavy industrial environments where controlled AC power delivery is critical. Typical applications include AC motor soft starters, variable speed drives, resistance welding controllers, industrial heating and temperature regulation systems, and UPS input stage control. It is also found in crane and hoist drive systems, pump and fan controllers, and power conversion equipment in steel mills, paper mills, and process manufacturing plants. The 1200V voltage class provides adequate margin for 480V and 690V three-phase bus applications subject to transient overvoltage events.

Key Features of the TT92N12KOF:

• 92A average on-state current (IT(AV)) with 1200V repetitive peak off-state voltage rating for 480V and 690V three-phase systems
• Isolated copper baseplate construction enabling direct heatsink mounting with standard thermal interface materials
• Low on-state voltage drop (VT) minimizes conduction losses and reduces thermal stress in continuous duty cycles
• High dV/dt and dI/dt capability supports reliable operation in converter and inverter topologies with steep voltage transients
• Standard gate trigger current and voltage parameters compatible with conventional SCR driver and firing board circuits
• Compact module footprint simplifies retrofits and drop-in replacements for legacy phase-control drive platforms

With a factory lead time of 99 weeks for new production, the TT92N12KOF presents a serious procurement challenge for maintenance and MRO teams managing unplanned equipment failures or scheduled overhauls. Waiting nearly two years for a replacement module is not an operational option for most facilities. ATI Accurate Technology maintains inventory of hard-to-find and long-lead-time thyristor modules precisely for these situations. Whether you need a single unit for an emergency repair or a standing stock of spares to protect critical production equipment, ATI provides an immediate solution without the factory queue.
