The SEMIKRON SKKT25/10 is a dual SCR (thyristor) module configured in an isolated base package delivering 25A average on-state current and 1000V repetitive peak off-state voltage (VDRM/VRRM). Built to SEMIKRON's SKKT platform standards, the module integrates two thyristors in a common housing with an isolated copper baseplate, enabling direct mounting to a heatsink without additional insulation. Gate trigger characteristics are optimized for reliable firing across industrial control circuits, making this module a dependable choice for phase-controlled rectification and power regulation designs.

The SKKT25/10 is well suited for industrial AC motor soft-starters, resistance heating controllers, transformer tap changers, and three-phase phase-control bridge assemblies. It is also deployed in UPS input stages, battery chargers, and DC drive front ends where controlled rectification at medium current levels is required. The module's isolated baseplate simplifies thermal management in densely packed control cabinets, and its robust thyristor die construction supports repetitive surge and inrush conditions common in industrial load cycling environments.

Quick Reference: SKKT25/10

Key Features of the SKKT25/10:

• Dual SCR configuration in a single isolated-base module — reduces component count and simplifies PCB or busbar integration
• 1000V VDRM/VRRM blocking voltage with high dV/dt immunity for robust performance in noisy industrial line environments
• 25A average on-state current with specified surge current (ITSM) capability to handle startup inrush in motor and transformer loads
• Isolated copper baseplate for direct heatsink mounting without supplemental mica or thermal pad insulation, lowering junction-to-case thermal resistance
• Gate trigger parameters compatible with standard opto-isolated and pulse transformer firing circuits used in industrial phase control boards
• SEMIKRON SKKT package format with standardized footprint, enabling drop-in replacement across multiple current and voltage class variants

The SKKT25/10 carries a factory lead time of approximately 35 weeks for new production orders, a reality that catches many maintenance and procurement teams off guard during unplanned equipment failures. SEMIKRON thyristor modules in this current and voltage class are embedded in legacy drive systems, heating controllers, and rectifier assemblies that remain in service well beyond original design life. ATI Accurate Technology specializes in locating exactly these kinds of long-lead and hard-to-find power semiconductors through established distributor and broker networks, helping engineers avoid extended production downtime while factory orders are queued.

ATI Accurate Technology is a power semiconductor distributor based in Palmetto, Florida, stocking IGBTs, thyristors, diodes, and rectifier modules including obsolete and long-lead-time parts. Orders placed before 5PM EST ship same day when stock is on hand. For SKKT25/10 availability, volume pricing, and lead time options, call 239-734-7566 or email sales@igbts.us.
