The Infineon TTB6C110N14KOF is a three-phase fully controlled thyristor bridge module engineered for high-reliability AC-DC power conversion. Rated at 110A average current and 1400V repetitive peak off-state voltage (VDRM/VRRM), this module integrates six thyristors in a compact, isolated-base housing suitable for demanding environments. Its robust gate trigger characteristics and low thermal resistance make it a preferred solution for engineers designing or maintaining industrial drives, power supplies, and soft-start systems where repeatable, stable phase control is essential.

The TTB6C110N14KOF sees broad deployment across industrial sectors including AC motor soft starters, DC drive front-end converters, electrochemical rectifiers, crane and hoist drives, heating element controllers, and uninterruptible power supply (UPS) systems. The module's 1400V voltage class provides the necessary margin for 690VAC line applications, while the 110A current rating suits mid-range drive platforms. Its standardized footprint simplifies drop-in replacement in OEM equipment and legacy systems still operating in the field.

Quick Reference: TTB6C110N14KOF

Key Features of the TTB6C110N14KOF:

• 1400V VDRM/VRRM repetitive peak voltage rating — provides full margin for 690VAC three-phase line operation
• 110A IT(AV) average on-state current with optimized thermal resistance for efficient heat transfer to external heatsink
• Fully controlled three-phase bridge (B6C) topology — six thyristors integrated in a single isolated-base module for simplified assembly
• Low gate trigger current (IGT) and reliable dv/dt and di/dt ratings suited for phase-angle firing control circuits
• Electrically isolated baseplate — enables direct mounting to system heatsinks without additional isolation hardware in most configurations
• Compliant with standard Infineon SEMIPACK footprint — facilitates direct replacement of equivalent modules in legacy equipment

With a published factory lead time of 99 weeks, the TTB6C110N14KOF represents exactly the type of long-lead, hard-to-plan component that can halt production or delay capital projects when not proactively sourced. Infineon's extended production scheduling for this class of thyristor module means that waiting until a failure or a project BOM is finalized is a significant operational risk. Procurement teams supporting active manufacturing lines, OEM service depots, or multi-year capital installations should treat current available inventory as a strategic stocking opportunity rather than a just-in-time purchase.

ATI Accurate Technology, based in Palmetto, Florida, stocks the TTB6C110N14KOF in new OEM condition ready for same-day shipment on orders received before 5PM EST.
