The SEMIKRON SKKT27B14E is a dual thyristor (SCR) module combining two SCR elements in a common isolated base package rated for 27A average on-state current and 1400V repetitive peak off-state voltage (VDRM/VRRM). Built to SEMIKRON's SKKT form factor, it features an electrically isolated copper base for direct heatsink mounting without additional isolation hardware. This module is engineered for demanding phase-control and rectification applications where high blocking voltage, thermal reliability, and repeatable gate-trigger characteristics are non-negotiable requirements in industrial power conversion systems.

The SKKT27B14E is widely deployed in AC/DC converters, DC motor soft starters, crane and hoist drives, resistance welding controllers, and electrochemical process rectifiers. Its 1400V voltage class provides adequate margin in 690V AC line environments, making it a preferred solution for heavy industrial machinery operating on European and North American high-voltage distribution networks. The module is also found in UPS systems, battery chargers, and field excitation circuits for synchronous machines where stable, controlled current delivery is critical to process integrity and equipment longevity.

Key Features of the SKKT27B14E:

• Dual SCR configuration in a single isolated-base module, enabling simplified half-wave or full-wave circuit topologies with reduced component count
• 1400V VDRM/VRRM rating provides robust voltage margin for 690V AC three-phase line applications and transient overvoltage environments
• 27A IT(AV) per thyristor supports continuous phase-control operation in industrial drive and converter designs
• Electrically isolated copper base plate allows direct mounting to standard heatsinks without additional insulating pads, reducing thermal interface resistance
• SEMIKRON SKKT package offers a proven, industry-standard footprint compatible with existing drive and converter designs for straightforward drop-in replacement
• Low gate trigger current and voltage specifications support reliable firing across wide temperature ranges in demanding control circuit designs

The SKKT27B14E carries a factory lead time of approximately 35 weeks for new production, placing it firmly in the long-lead-time category that can halt repair timelines or delay new builds. SEMIKRON thyristor modules at the 1400V class are periodically subject to production scheduling constraints and allocation, making early procurement essential. ATI Accurate Technology maintains an active sourcing network for hard-to-find and long-lead SEMIKRON components, helping maintenance and procurement teams avoid costly downtime. Whether you need a single replacement unit or are building buffer stock, contacting ATI early in your project cycle is the most effective mitigation strategy.
