The SEMIKRON SKKT213/18E is a dual SCR (thyristor) power module configured in a common-cathode or common-anode topology within the proven SKKT platform, rated for 213A average on-state current (ITAV) and 1800V repetitive peak off-state voltage (VDRM/VRRM). Designed to handle high-current phase-control and rectification duties, this module integrates two thyristors in a single isolated base package, simplifying assembly and reducing bus bar complexity in high-power converter designs. Its robust silicon technology and pressure-contact construction ensure consistent performance across wide temperature ranges in continuous industrial operation.

The SKKT213/18E is widely deployed in heavy industrial applications including AC and DC motor drives, crane and hoist drive systems, industrial power supplies, soft starters, excitation systems for synchronous machines, and electrochemical process rectifiers. It is equally at home in regenerative braking topologies, UPS front-end converters, and large-scale heating control systems where phase-angle firing at high current levels demands proven SCR reliability. Its 1800V voltage class provides the necessary margin for 690V and 1000V AC line applications after accounting for transient overvoltage conditions.

Key Features of the SKKT213/18E:

• Dual SCR topology in a single isolated base package — simplifies three-phase bridge assembly and reduces component count
• 1800V VDRM/VRRM rating provides robust voltage margin for 690V and 1000V AC line converter designs
• 213A ITAV continuous on-state current supports high-power phase-control and line-commutated rectifier circuits
• Low thermal resistance (RthJC) enables efficient heat transfer to external heatsinks, supporting full-rated current at elevated ambient temperatures
• Isolated copper base plate allows direct mounting to chassis or liquid-cooled heatsinks without additional electrical isolation hardware
• Gate trigger characteristics optimized for reliable firing with standard SCR gate drive circuits across the full operating temperature range

With a 32-week factory production lead time, the SKKT213/18E presents a significant procurement challenge for maintenance teams facing unplanned equipment failures or OEM production schedules. SEMIKRON's SKKT-series modules have long lifecycles but can enter allocation or extended lead times as wafer production is planned in batches. ATI Accurate Technology actively monitors distributor networks and maintains relationships with authorized channel partners to source these modules ahead of standard lead times wherever possible. Engaging ATI early in your planning cycle is the most effective strategy for protecting uptime and avoiding costly production delays caused by this long-lead-time component.

ATI Accurate Technology is based in Palmetto, Florida and stocks a deep inventory of SEMIKRON thyristor modules, IGBTs, diodes, and rectifier assemblies. We offer same-day shipping on qualifying in-stock orders placed before 5PM EST, and our team provides responsive support for urgent maintenance and volume procurement needs.
