The Infineon TT61N16KOF-K is a thyristor (SCR) module combining two thyristors in a single isolated package, rated for 61A average on-state current and 1600V repetitive peak off-state voltage. Built to Infineon's industrial-grade standards, this module delivers reliable phase-control and AC switching performance in demanding environments. Its robust construction and high blocking voltage make it a preferred choice for engineers designing or maintaining systems where thermal stability, low switching losses, and long service life are non-negotiable requirements.

The TT61N16KOF-K sees wide deployment across industrial power conversion and process control applications. Common platforms include AC motor soft starters, thyristor power controllers for resistance heating and temperature regulation, battery charging systems, UPS topologies, and DC drive front-end rectifier stages. Its 1600V voltage class provides the necessary derating margin for 690VAC three-phase supply environments, while the dual thyristor configuration simplifies half-wave or anti-parallel circuit layouts and reduces PCB real estate in control panel designs.

Quick Reference: TT61N16KOF-K

Key Features of the TT61N16KOF-K:

• 1600V repetitive peak off-state voltage (VDRM/VRRM) — suitable for 690VAC three-phase applications with standard derating
• 61A average on-state current (IT(AV)) — supports continuous phase-control duty in AC power regulation systems
• Dual thyristor configuration in a single isolated baseplate module — enables compact anti-parallel or half-wave circuit integration
• Low on-state voltage drop (VTM) — reduces conduction losses and thermal stress in continuous-duty installations
• High dI/dt and dV/dt ratings — ensures stable triggering response in fast-switching phase-control and soft-start applications
• Isolated copper baseplate — allows direct heatsink mounting without additional isolation hardware, simplifying thermal management

With a current factory lead time of 99 weeks, procurement teams relying solely on the Infineon supply chain face serious exposure to production halts and extended equipment downtime. The TT61N16KOF-K appears across legacy industrial drives, heating controllers, and power conditioning systems that remain in active service well beyond original production runs. For MRO buyers, OEMs managing EOL risk, and field engineers facing an unplanned failure, sourcing from a stocking distributor with verified new OEM inventory is the only practical path to keeping operations on schedule.
