The SEMIKRON SKKT213/16E is a dual SCR (thyristor) power module delivering 213A average on-state current and a 1600V repetitive peak off-state voltage (VDRM/VRRM). Housed in SEMIKRON's industry-standard SKKT package, this module integrates two thyristors in a common-cathode or common-anode configuration suited for three-phase bridge and anti-parallel circuit topologies. Its isolated copper base plate and pressure-contact construction ensure reliable thermal transfer to heatsinks, making it a dependable choice for high-power, thermally demanding environments where consistent gate control and forward current handling are critical.

The SKKT213/16E is a proven solution across a broad range of industrial power conversion applications. Engineers specify this module in AC motor soft starters, DC motor drives, industrial rectifiers, crane and hoist controls, and resistance welding equipment. It is also widely deployed in UPS systems, induction heating, electrochemical processing, and regenerative braking circuits. Its high blocking voltage and robust current rating make it particularly valuable in medium-voltage drive platforms and heavy industrial machinery where reliability under continuous load cycling is non-negotiable.

Key Features of the SKKT213/16E:

• 213A average on-state current (IT(AV)) with high surge current capability (ITSM) for demanding load profiles
• 1600V VDRM/VRRM blocking voltage rating, suitable for medium-voltage three-phase rectifier and converter bridges
• Dual thyristor configuration in a single SKKT package enabling compact common-cathode or common-anode bridge assemblies
• Isolated aluminum oxide (Al₂O₃) ceramic base plate providing electrical isolation with low thermal resistance for efficient heatsink mounting
• Industry-standard SKKT package footprint ensuring direct form-fit-function replacement compatibility with legacy and current drive platforms
• Designed for phase-controlled converter duty with stable gate trigger characteristics across the full operating temperature range

The SKKT213/16E carries a factory lead time of approximately 30 weeks for new production from SEMIKRON, placing it firmly in the long-lead-time category. For OEMs managing production schedules and maintenance teams facing unplanned equipment downtime, this lead time presents a real operational risk. ATI Accurate Technology actively sources SKKT-series thyristor modules through authorized and vetted supply channels, helping customers bridge procurement gaps. Whether you need a single replacement unit or a larger buffer stock quantity, contacting ATI early in your planning cycle is the most effective strategy to avoid extended downtime.
