The SEMIKRON SKKT25/16 is a dual SCR thyristor module delivering 25A average on-state current at a 1600V repetitive peak off-state voltage (VDRM/VRRM). Built in SEMIKRON's established SKKT package, this module integrates two thyristors sharing a common baseplate for simplified thermal management and compact board layout. Designed for phase-controlled rectification, soft-start circuits, and AC power regulation, the SKKT25/16 offers reliable switching performance and low on-state voltage drop, making it a dependable choice for demanding industrial power conversion environments.

The SKKT25/16 is widely deployed in industrial DC drives, field excitation systems, battery chargers, uninterruptible power supplies, and resistance welding equipment where controlled, high-voltage rectification is essential. Its robust construction handles the repetitive surge currents and thermal cycling inherent in motor control and process heating applications. The module's screw-mount baseplate ensures consistent thermal contact with heat sinks, supporting continuous operation in harsh factory environments where uptime and thermal reliability are non-negotiable.

Quick Reference: SKKT25/16

Key Features of the SKKT25/16:

• 1600V VDRM/VRRM repetitive peak off-state voltage for high-line and international voltage applications
• 25A average on-state current (IT(AV)) with high surge current (ITSM) capability for short-circuit and inrush tolerance
• Dual thyristor configuration in a single SKKT package, enabling compact B2 or B6 bridge topologies with fewer components
• Isolated copper baseplate construction rated for direct heat sink mounting, minimizing thermal resistance and supporting forced-air or liquid-cooled assemblies
• Low on-state voltage drop (VT) reduces conduction losses and heat generation in continuous-duty rectifier stages
• Compatible with standard SEMIKRON SKKT footprint, simplifying like-for-like replacement in existing drive and converter platforms

The SKKT25/16 carries a factory lead time of approximately 38 weeks for new production, a reality increasingly common across SEMIKRON's thyristor module line as global semiconductor supply chains remain constrained. Procurement teams managing MRO inventory, capital equipment refurbishment, or OEM production schedules cannot afford to wait on standard distribution channels. ATI Accurate Technology maintains relationships with authorized distribution networks and excess inventory sources specifically to bridge these gaps for engineers and buyers who need SKKT-series modules without multi-month delays.
