The SEMIKRON SKKT107B16E is a dual thyristor (SCR) module configured in a common cathode arrangement, rated for 107A average on-state current (IT(AV)) and 1600V repetitive peak off-state voltage (VDRM/VRRM). Housed in the industry-standard SKKT pressure-contact power package, this module is engineered for high-efficiency phase control, soft-start circuits, and AC power regulation in medium- to high-power industrial systems. Its isolated baseplate construction simplifies heatsink integration and meets the thermal demands of continuous-duty operation in harsh environments.

The SKKT107B16E is widely deployed across industrial drive systems, DC motor controllers, resistance welding equipment, UPS systems, electrochemical processing rectifiers, and crane and hoist control applications. Its 1600V voltage class provides the necessary blocking margin for 690V AC line-connected systems, while the 107A current rating supports mid-range power conversion stages where reliable, controllable SCR switching is critical. OEM equipment manufacturers and MRO teams maintaining legacy industrial platforms consistently specify this SEMIKRON module for its proven long-term field reliability.

Key Features of the SKKT107B16E:

• Dual thyristor common cathode configuration suitable for three-phase bridge and midpoint rectifier topologies
• 1600V VDRM/VRRM blocking voltage providing adequate margin for 690V AC bus applications with transient overvoltage protection requirements
• 107A average on-state current (IT(AV)) with low on-state voltage drop (VT) for reduced conduction losses in continuous-duty cycles
• Isolated aluminum oxide (Al₂O₃) baseplate for direct heatsink mounting, minimizing thermal resistance and simplifying module-level thermal management
• High dI/dt and dV/dt ratings suited for phase-angle firing and line-frequency switching in industrial converter designs
• Compatible with standard SEMIKRON SKKT footprint, enabling direct form-fit-function replacement in existing equipment without mechanical redesign

The SKKT107B16E carries a factory lead time of approximately 32 weeks for new production from SEMIKRON, placing it firmly in the long lead time category that creates serious risk for maintenance teams managing unplanned downtime or capital project schedules. ATI Accurate Technology actively sources hard-to-find and extended lead time SEMIKRON thyristor modules through authorized and vetted supply channels. Whether you need a single replacement unit for emergency MRO or a scheduled quantity for a build or upgrade project, ATI has the sourcing expertise to locate verified new OEM stock when standard distribution cannot meet your timeline.

ATI Accurate Technology is headquartered in Palmetto, Florida, and ships same-day on orders placed before 5PM EST. We specialize in IGBTs, thyristors, diodes, and rectifier modules — including obsolete and long lead time parts that other distributors can't source.
