The EUPEC TTB6C110N12KOF is a three-phase bridge thyristor module rated for 110A average on-state current and a 1200V repetitive peak off-state voltage. Built to EUPEC's proven module packaging standards, it integrates a fully controlled three-phase thyristor bridge into a compact, thermally efficient housing suited for demanding industrial environments. Isolation voltage, low thermal resistance junction-to-case, and robust gate trigger characteristics make this module a reliable choice for phase-controlled power conversion in high-cycle-rate applications where component longevity and predictable switching behavior are non-negotiable.

The TTB6C110N12KOF is widely deployed in industrial AC drives, soft starters, DC motor drive front ends, electrochemical rectifiers, and UPS input stages. Its three-phase fully controlled bridge topology makes it well-suited for applications requiring precise phase-angle control over output voltage and current, including resistance heating systems, excitation regulators for synchronous machines, and regenerative braking circuits. The module's 1200V blocking capability provides adequate margin for 480V and 690V three-phase mains with transient overvoltage exposure typical of industrial plant environments.

Key Features of the TTB6C110N12KOF:

• 110A average on-state current (IT(AV)) with robust thermal design for continuous industrial duty cycles
• 1200V repetitive peak off-state voltage (VDRM/VRRM) providing margin on 480V and 690V three-phase systems
• Fully controlled three-phase bridge configuration enabling bidirectional power flow and phase-angle output regulation
• Low thermal resistance (junction-to-case) supporting effective heat dissipation when mounted to appropriate heatsink
• High isolation voltage between terminals and baseplate for safe integration into grounded chassis assemblies
• EUPEC-standard gate trigger sensitivity ensuring compatibility with standard SCR gate driver circuits used in legacy and modern drive platforms

EUPEC thyristor modules of this series have been out of active production for an extended period, and new factory orders carry a lead time of 99 weeks — well beyond the tolerance of most maintenance or production schedules. For OEMs sustaining legacy drive platforms and maintenance teams managing fleet repairs, waiting on new production is rarely viable. Availability of genuine new OEM stock from a specialized distributor is the practical path forward. Substitution with alternate part numbers risks dimensional, electrical, or trigger characteristic mismatches that can compromise system reliability or damage gate driver circuits.
