The SEMIKRON SKKT25/06 is a dual thyristor (SCR) module from the SEMIPACK series, rated for 25A average on-state current and 600V repetitive peak off-state voltage (VDRM/VRRM). Housed in SEMIKRON's industry-standard SEMIPACK 1 package, this module integrates two thyristors in a common-cathode or inverse-parallel configuration suitable for fully controlled rectifier and AC power controller topologies. Its isolated baseplate, industry-standard footprint, and robust thermal characteristics make it a proven choice for demanding industrial power electronics designs.

The SKKT25/06 is widely deployed in variable-speed AC and DC motor drives, soft starters, resistance heating controllers, industrial UPS systems, and three-phase fully controlled bridge rectifiers. Its phase-control capability makes it equally suited for electrochemical process equipment, crane and hoist drives, and mill auxiliary drives where precise torque and speed regulation under heavy cyclic loads are required. OEM machine builders and MRO procurement teams across process industries rely on the SKKT25/06 as a long-service-life building block in medium-power converter stages.

Quick Reference: SKKT25/06

Key Features of the SKKT25/06:

• Dual SCR configuration in SEMIKRON SEMIPACK 1 package — enables fully controlled bridge or AC controller designs with minimal external hardware
• 600V VDRM/VRRM blocking voltage with high dV/dt and dI/dt ruggedness for inductive and reactive load environments
• 25A IT(AV) continuous on-state current with low on-state voltage drop (VT) for reduced conduction losses and improved thermal efficiency
• Electrically isolated copper baseplate for direct heatsink mounting, simplifying thermal stack design and reducing system insulation requirements
• Industry-standard SEMIPACK footprint ensures drop-in compatibility with legacy SEMIKRON and equivalent third-party module positions
• Gate trigger current and holding current characteristics optimized for standard SCR gate driver circuits used in phase-control applications

The SKKT25/06 carries a factory lead time of approximately 33 weeks for new production, a reality that reflects broader supply chain pressures on SEMIKRON SEMIPACK modules. For maintenance engineers managing aging drives or soft starters, and for procurement professionals building safety stock, waiting on factory orders is often not operationally viable. ATI Accurate Technology actively sources long-lead-time and hard-to-find SEMIKRON thyristor modules through established distributor and excess inventory channels, helping customers avoid extended equipment downtime or production delays.

ATI Accurate Technology is headquartered in Palmetto, Florida and stocks power semiconductors for same-day shipping on orders placed before 5PM EST.
