The SEMIKRON SKKT210/16E is a dual thyristor (SCR) module delivering 210A average on-state current (IT(AV)) and a 1600V repetitive peak off-state voltage (VDRM/VRRM). Built in SEMIKRON's proven SEMIPACK2 platform, this module integrates two SCR elements in a common isolated baseplate package, simplifying heatsink mounting and bus bar connections. Its thermally optimized design supports high-power density installations where reliable phase control and switching performance are non-negotiable. Engineers specify the SKKT210/16E where robustness, established thermal ratings, and long service life are critical requirements.

The SKKT210/16E is widely deployed across heavy industrial sectors where controlled rectification and AC power regulation are essential. Typical applications include three-phase controlled rectifier bridges in DC motor drives, soft starters for large induction motors, excitation systems for synchronous generators, resistance heating controllers, electrochemical process power supplies, and crane or hoist drive systems. Its high blocking voltage and substantial current rating make it equally suitable for regenerative drive topologies and UPS input stage rectifiers operating on 690V or higher distribution systems common in European and heavy industrial environments.

Key Features of the SKKT210/16E:

• Dual SCR configuration (common cathode or common anode configurable) in a compact SEMIPACK2 package for simplified bridge circuit assembly
• 210A IT(AV) per thyristor element with high surge current capability (ITSM) suitable for demanding pulse and fault-withstand requirements
• 1600V VDRM/VRRM blocking voltage providing robust margin on 690V and higher AC distribution networks
• Electrically isolated copper baseplate enables direct mounting to standard heatsinks without additional isolation hardware, reducing assembly complexity
• Low thermal resistance junction-to-case (Rth(j-c)) supports efficient heat dissipation at full rated load in continuous industrial duty cycles
• Gate trigger characteristics optimized for compatibility with standard SCR firing boards and phase-control gate driver circuits across a wide temperature range

With a factory lead time of approximately 38 weeks for new production, procurement teams relying solely on the OEM supply chain face significant schedule risk for maintenance spares, retrofit projects, or unplanned equipment failures. ATI Accurate Technology specializes in sourcing long-lead-time and hard-to-find SEMIKRON thyristor modules like the SKKT210/16E through established distribution channels. Engaging ATI early in your procurement cycle—or maintaining a conversation about buffer stock—can protect your operation from costly downtime caused by extended delivery windows on critical power semiconductor components.

ATI Accurate Technology is headquartered in Palmetto, Florida, and stocks a broad range of power semiconductors including IGBTs, thyristors, diodes, and rectifier modules.
