The SEMIKRON SKKT26/12D is a dual SCR (thyristor) power module configured in a common cathode or inverse parallel arrangement, rated for 26A average on-state current and a 1200V repetitive peak off-state voltage (VDRM/VRRM). Housed in SEMIKRON's industry-standard SKKT package with an isolated copper baseplate, this module delivers efficient thermal management and straightforward heatsink integration. It is engineered for demanding AC and DC power control applications where reliable gate triggering, low on-state losses, and rugged blocking performance are essential requirements.

The SKKT26/12D is widely deployed in industrial AC motor soft starters, DC drive front-end converters, resistance welding controllers, induction heating systems, and UPS input rectifier stages. Its robust 1200V blocking capability provides adequate voltage margin for 480V and 690V three-phase industrial line voltages, while the 26A current rating fits mid-range power conversion designs. Crane and hoist drives, electrochemical process rectifiers, and industrial temperature control systems represent additional application areas where this thyristor module performs reliably under continuous and demanding duty cycles.

Key Features of the SKKT26/12D:

• Dual SCR configuration in a compact SKKT package, enabling simplified B2 or B6 bridge circuit assembly with minimal external hardware
• 1200V VDRM/VRRM repetitive peak off-state voltage with adequate dV/dt and dI/dt ratings for industrial line-commutated converter designs
• 26A average on-state current with low VT(TO) threshold voltage, minimizing conduction losses and reducing heatsink thermal resistance requirements
• Isolated copper baseplate construction provides electrical isolation from heatsink while maintaining low junction-to-case thermal resistance for efficient heat dissipation
• Industry-standard SKKT footprint ensures direct form-fit-function interchangeability with compatible modules across SEMIKRON's product family
• Tight gate trigger current (IGT) and holding current (IH) parameters support reliable firing across a wide temperature range in phase-angle and burst-fire control topologies

The SKKT26/12D carries a factory lead time of approximately 38 weeks for new production, which is typical for SEMIKRON thyristor modules in this voltage and current class. Supply chain disruptions and end-of-life production schedules have made modules like this increasingly difficult to source through standard distribution channels. ATI Accurate Technology maintains an active network of verified suppliers and warehouse stock specifically to support engineers and procurement teams facing long lead times, obsolescence challenges, or urgent equipment downtime scenarios requiring fast turnaround on hard-to-find SEMIKRON power modules.
