The Semikron SKKT26/14E is a dual thyristor (SCR) module delivering 26A average on-state current and a 1400V repetitive peak reverse voltage (VRRM) rating. Built in Semikron's industry-standard SKKT package, this module integrates two thyristors in a common isolated base configuration, simplifying assembly and thermal management in demanding power conversion equipment. With a robust gate trigger interface and low thermal resistance, it is engineered for reliable, long-service-life operation in environments where device failure is not an option.

The SKKT26/14E is widely deployed in industrial AC/DC converters, variable-speed DC motor drives, soft starters, field excitation systems, and resistance heating controllers. Its 1400V voltage class provides essential voltage margin in 690VAC line applications or wherever transient overvoltages must be absorbed without device stress. The isolated baseplate mount integrates directly onto standard heatsinks, making it a drop-in solution for OEM equipment rebuilds, retrofit projects, and new panel designs across metals processing, material handling, marine, and oil-and-gas industries.

Quick Reference: SKKT26/14E

Key Features of the SKKT26/14E:

• 26A average on-state current (IT(AV)) with 1400V VRRM — suitable for 690VAC three-phase line operation with standard derating margins
• Dual thyristor common-cathode or common-anode configuration enables single-module antiparallel or half-controlled bridge topologies
• Isolated copper baseplate provides electrical isolation from heatsink, simplifying mechanical mounting in multi-device assemblies
• Low thermal resistance junction-to-case (Rth(j-c)) supports high power density designs with minimal heatsink requirement
• Semikron SKKT package footprint is industry-standardized, allowing direct interchangeability with equivalent modules from compatible manufacturers
• Qualified for phase-angle firing control at frequencies up to 60Hz with proven gate sensitivity for reliable turn-on across the full current range

The SKKT26/14E carries a factory lead time of approximately 40 weeks for new production orders, reflecting current semiconductor supply chain conditions for thyristor modules in this voltage class. For maintenance operations, emergency replacements, or projects that cannot absorb a 40-week wait, working with a specialized distributor like ATI is critical. ATI maintains active sourcing relationships and inventory pipelines specifically for long-lead-time and hard-to-find Semikron thyristor modules, helping engineers and procurement teams avoid costly equipment downtime while production queues remain extended.
