The SEMIKRON SKKT213/16D is a dual thyristor (SCR) module in the SEMIPACK 3 package, rated for 213A average on-state current and a 1600V repetitive peak off-state voltage (VDRM/VRRM). Configured as two thyristors in an isolated base housing, this module is engineered for phase-controlled rectifier bridges, AC power controllers, and soft-start assemblies where high blocking voltage and robust thermal performance are critical. The isolated copper base simplifies heatsink mounting and supports tight thermal management in high-power cabinet designs.

The SKKT213/16D is widely specified in industrial motor soft starters, resistance heating controllers, crane and hoist drives, DC motor speed controllers, and three-phase bridge rectifiers for process industry equipment. Its performance envelope suits demanding cycles in steel mills, paper machinery, plastics extrusion lines, and heavy-duty HVAC systems. OEMs and MRO engineers depend on this module in legacy drive platforms where the thyristor module forms the core of the power conversion stage and long-term parts continuity is essential.

Key Features of the SKKT213/16D:

• 213A average on-state current (IT(AV)) with high surge current capability for robust overcurrent tolerance
• 1600V VDRM/VRRM blocking voltage supporting high-line industrial supply voltages with adequate safety margin
• Dual thyristor configuration in a single SEMIPACK 3 isolated-base package — simplifies bridge and anti-parallel circuit layouts
• Electrically isolated copper base plate for direct heatsink mounting, enabling low thermal resistance and efficient junction-to-case heat dissipation
• Industry-standard SEMIPACK footprint ensuring dimensional and electrical interchangeability with compatible SEMIKRON and cross-reference devices
• Designed for phase-angle firing control with stable gate trigger characteristics across the full operating temperature range

The SKKT213/16D carries a factory lead time of approximately 29 weeks for new production — a reality that frequently creates unplanned downtime for maintenance teams and supply chain gaps for OEM production schedules. SEMIKRON thyristor modules in the 200A-class at 1600V are a known long lead time commodity, and waiting on standard distribution channels is not always viable. ATI Accurate Technology actively sources these modules through authorized and vetted supply chains, maintaining relationships that give customers options when factory lead times are prohibitive and production or repair schedules cannot wait.

ATI Accurate Technology is based in Palmetto, Florida, and ships same-day on orders placed before 5PM EST. We serve maintenance engineers, procurement teams, and OEM production lines with new SEMIKRON IGBTs, thyristors, diodes, and rectifier modules — including hard-to-find and long lead time parts.
