The SEMIKRON SKKT132/18E is a dual thyristor (SCR) module delivering 132A average on-state current and a 1800V repetitive peak reverse voltage (VRRM) rating. Built in SEMIKRON's industry-standard SEMIPACK topology, the module integrates two phase-leg SCRs in a single isolated base assembly, reducing bus-bar complexity and simplifying thermal management on a common heatsink. With low forward voltage drop and robust gate triggering characteristics, this module is engineered for demanding power conversion environments where reliable phase control is non-negotiable.

The SKKT132/18E sees extensive deployment across heavy industrial and commercial power conversion systems. Typical applications include three-phase fully controlled bridge rectifiers, AC motor soft starters, DC drive front-end converters, crane and hoist controls, induction heating power supplies, UPS systems, and electrochemical process rectifiers. Its 1800V voltage class provides the headroom required for 690V AC line-side installations where transient overvoltages must be absorbed without nuisance triggering or device stress, making it a preferred choice for OEM drive builders and field service engineers alike.

Key Features of the SKKT132/18E:

• 132A average on-state current (IT(AV)) with high surge current (ITSM) capability suitable for fault-tolerant converter designs
• 1800V VRRM rating providing robust margin for 690V AC three-phase line-side applications with transient overvoltage exposure
• Dual SCR configuration in a single SEMIPACK housing enables compact, symmetrical phase-leg assembly on shared heatsinks
• Isolated copper base with aluminum oxide substrate ensures high dielectric withstand voltage and efficient thermal transfer to heatsink
• Low on-state voltage (VT) and predictable gate trigger current (IGT) characteristics simplify firing circuit design and thermal budgeting
• Compatible with SEMIKRON SEMIPACK mechanical footprint, enabling like-for-like replacement in existing drive and rectifier chassis

The SKKT132/18E carries a current factory lead time of approximately 99 weeks for new production orders from SEMIKRON—a reality that can paralyze maintenance schedules and halt production lines when a module fails unexpectedly. ATI Accurate Technology specializes in sourcing exactly these types of long-lead-time, hard-to-find, and obsolescence-risk power semiconductors. Our procurement network allows us to locate verified new OEM inventory outside standard distribution channels, giving maintenance engineers and procurement teams a viable path to keep critical equipment running without waiting nearly two years for factory fulfillment.

ATI Accurate Technology is headquartered in Palmetto, Florida, and ships same-day on orders placed before 5PM EST. Whether you need a single replacement module or volume quantities for a fleet maintenance program, our team is ready to assist.
