The SKKT210/12E is a SEMIKRON dual SCR (thyristor) module from the SEMIPACK series, rated for 210A average on-state current and a 1200V repetitive peak off-state voltage (VDRM/VRRM). Designed for phase-controlled rectifier and AC power controller applications, this module integrates two thyristors in a common base package, simplifying busbar connections and heatsink mounting. The isolated copper base plate ensures reliable thermal transfer to the heatsink, while the industry-standard footprint supports direct replacement in existing converter assemblies without mechanical redesign.

The SKKT210/12E is widely deployed in industrial drives, soft starters, DC motor controllers, crane and hoist systems, welding power supplies, and electrochemical process rectifiers. Its robust current and voltage ratings make it suitable for three-phase bridge rectifier configurations in heavy industrial environments where continuous duty cycles and high surge current capability are essential. Utilities, steel mills, chemical processing plants, and marine drive OEMs rely on SEMIPACK thyristor modules of this class as the core switching element in medium-power AC-to-DC conversion stages.

Key Features of the SKKT210/12E:

• Dual SCR configuration in a single SEMIPACK module, supporting half-controlled and fully-controlled bridge topologies
• 1200V VDRM/VRRM blocking voltage with 210A IT(AV) continuous current rating for medium-to-high power phase control
• Isolated copper base plate construction for low thermal resistance and compatibility with standard aluminum extrusion heatsinks
• High surge current capability (ITSM) suitable for applications with inrush events and short-circuit overcurrent conditions
• Industry-standard SEMIPACK footprint enables direct form-fit-function replacement of equivalent modules from compatible series
• Gate trigger characteristics optimized for resistive and inductive load phase control at industrial line frequencies (50/60Hz)

The SKKT210/12E carries a factory lead time of approximately 36 weeks for new production orders, placing it firmly in the long lead-time category that strains MRO and capital project timelines alike. Procurement teams supporting aging drive systems or mid-project converter builds cannot afford to wait nine months for a critical switching element. ATI Accurate Technology actively sources SEMIPACK thyristor modules through authorized and independent distribution channels, maintaining visibility into surplus, excess, and broker inventory that bypasses standard factory queues. Contacting ATI early in your project planning cycle is the most effective way to secure allocation.

ATI Accurate Technology is based in Palmetto, Florida and specializes in power semiconductors including hard-to-find, long lead-time, and obsolete IGBTs, thyristors, diodes, and rectifier modules.
