The SEMIKRON SKKT56/10D is a dual SCR (thyristor) module housed in the industry-standard SKKT package, rated for 56A average on-state current (IT(AV)) and a 1000V repetitive peak off-state voltage (VDRM/VRRM). Designed for phase-controlled rectification and AC power switching, this module integrates two thyristors in a common base isolated package, simplifying heatsink mounting and reducing system assembly complexity. With a low profile, robust copper base, and industry-proven gate characteristics, the SKKT56/10D is engineered for continuous duty in high-reliability power conversion systems.

The SKKT56/10D sees broad deployment across industrial power electronics including DC motor drives, soft-start units, resistance heating controllers, welding equipment power supplies, and field excitation circuits for AC generators. Its dual-SCR configuration makes it a natural fit for anti-parallel or series configurations in controlled rectifier bridges. OEM machine builders and MRO teams servicing legacy drive systems — including those from ABB, Siemens, and Eurotherm — frequently specify this module as a direct replacement or upgrade component in existing thyristor-based drive platforms.

Key Features of the SKKT56/10D:

• Dual SCR configuration in a single isolated base package — ideal for half-controlled or fully-controlled bridge topologies
• 1000V VDRM/VRRM blocking voltage with high dV/dt immunity suited to line-commutated converter environments
• 56A IT(AV) continuous current rating with low on-state voltage drop (VT) for reduced conduction losses and thermal stress
• Electrically isolated copper base plate enables direct heatsink mounting without additional isolation hardware
• Standard SKKT footprint provides drop-in interchangeability with other SEMIKRON and compatible third-party SKKT-series modules
• Gate trigger parameters optimized for phase-control firing circuits operating from conventional SCR trigger boards and thyristor controllers

The SKKT56/10D carries a factory lead time of approximately 27 weeks for new production orders — a reality that can halt production lines, delay commissioning, or leave critical drive systems offline when standard channels fall short. ATI Accurate Technology specializes in navigating exactly these supply chain gaps. Whether you're facing an urgent field replacement, building safety stock ahead of a planned shutdown, or sourcing for a multi-unit OEM build, our procurement team works established distributor and broker networks to locate genuine SEMIKRON inventory and accelerate delivery timelines whenever possible.

ATI Accurate Technology is headquartered in Palmetto, Florida, and ships same-day on orders placed before 5PM EST. We stock IGBTs, thyristors, diodes, and rectifier modules including obsolete and long-lead-time parts that other distributors can't deliver. Volume pricing is available for qualified orders.
