The SEMIKRON SKKT92/16D is a dual SCR (thyristor) module delivering 92A average on-state current and a 1600V repetitive peak off-state voltage (VDRM/VRRM). Built on SEMIKRON's proven SEMIPAK platform, it features isolated copper base-plate construction, low thermal resistance, and robust gate sensitivity optimized for phase-control and line-commutated converter designs. The high blocking voltage rating and thermally efficient package make it a preferred choice in high-reliability power conversion systems where junction temperature management and long service life are critical requirements.

The SKKT92/16D is widely deployed across heavy industrial segments including AC and DC motor drives, soft-start units, resistance welding controllers, crane and hoist drive systems, uninterruptible power supplies, and three-phase bridge rectifier assemblies. Its dual SCR topology simplifies PCB and busbar layout in anti-parallel and common-cathode converter configurations, reducing overall system component count. The part is also found in renewable energy interface equipment, electrochemical process rectifiers, and industrial heating controllers where precise phase-angle firing control and high surge current capability are essential.

Key Features of the SKKT92/16D:

• Dual SCR topology with common cathode or anti-parallel configuration flexibility for three-phase bridge and AC controller circuits
• 1600V VDRM/VRRM blocking voltage providing robust margin in 480V–690V three-phase line applications
• 92A average on-state current (IT(AV)) with high surge current (ITSM) capability for reliable performance under transient overload conditions
• Isolated copper base-plate for direct heatsink mounting, enabling low junction-to-case thermal resistance and simplified thermal stack design
• High gate sensitivity with defined triggering parameters ensuring reliable firing across industrial control circuit voltage levels
• SEMIKRON SEMIPAK form factor offering standardized footprint compatibility with existing drive and rectifier platform designs

The SKKT92/16D carries a factory lead time of approximately 43 weeks for new production orders, reflecting current supply chain pressures on high-voltage thyristor modules across the industry. For maintenance teams facing unplanned downtime or procurement professionals building safety stock, waiting on new factory runs is rarely an option. ATI Accurate Technology specializes in bridging exactly this gap—maintaining sourcing networks for long-lead-time and hard-to-find SEMIKRON devices so your production line or repair schedule doesn't wait on a 43-week queue. Contact us early to discuss allocation and scheduling options.

ATI Accurate Technology is based 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.
