The SEMIKRON SKKT92B18E is a dual thyristor (SCR) module in the SEMIPACK 2 package format, rated for 92A average on-state current and 1800V repetitive peak off-state voltage (VDRM/VRRM). Configured as two independent SCRs in a common base package, the SKKT92B18E is engineered for phase-controlled rectification and AC power switching in industrial systems requiring high blocking voltage and consistent gate trigger sensitivity. SEMIKRON's proven isolation base and copper bond construction ensure low thermal resistance and long operational life under continuous load cycling.

The SKKT92B18E is widely deployed in industrial DC drives, soft starters, crane and hoist controllers, thyristor power controllers (TPCs), battery chargers, and welding power supplies. Its 1800V voltage class makes it particularly suited for 690V AC line-connected equipment where transient overvoltage margins must be maintained. The module also sees regular use in static VAR compensators, heating controllers, and three-phase bridge rectifier assemblies where paired SCR modules simplify layout and reduce assembly time on the power board.

Key Features of the SKKT92B18E:

• Dual SCR configuration in a single SEMIPACK 2 housing simplifies power stage layout and reduces component count
• 1800V VDRM/VRRM blocking voltage provides robust margin for 690V AC bus applications with transient protection requirements
• 92A average on-state current (IT(AV)) with low on-state voltage drop for efficient continuous power control operation
• Low thermal resistance junction-to-case (RthJC) enabling effective heat transfer to industry-standard heatsink profiles
• Isolated copper base plate with UL-recognized dielectric isolation for simplified heatsink grounding in multi-module assemblies
• Gate trigger characteristics optimized for reliable firing across industrial phase-control and zero-crossing gate drive circuits

The SKKT92B18E carries a factory lead time of approximately 32 weeks for new production orders, a reality common across SEMIKRON's SEMIPACK thyristor line as global demand for industrial power modules continues to pressure supply chains. For OEMs managing production schedules and maintenance teams facing unplanned downtime, waiting on factory lead times is rarely an option. ATI Accurate Technology actively sources long-lead-time and discontinued SEMIKRON modules through authorized and vetted distribution channels, often maintaining inventory ahead of factory availability for exactly these situations.
