The SEMIKRON SKKT25/14 is a dual SCR (thyristor) power module delivering 25A average on-state current (IT(AV)) with a 1400V repetitive peak off-state voltage (VDRM/VRRM). Built in SEMIKRON's established SKKT package, this module integrates two thyristors in a common-cathode or common-anode configuration on an isolated copper base, enabling direct heatsink mounting. Its low thermal resistance, robust gate triggering characteristics, and high blocking voltage make it a reliable choice for demanding controlled rectification and phase-control applications across industrial power electronics platforms.

The SKKT25/14 is widely deployed in three-phase fully controlled bridge rectifiers, soft starters, AC voltage regulators, and DC motor drive front ends where precise phase-angle control is essential. It is also found in resistance welding controllers, electrochemical process power supplies, UPS input stages, and industrial heating systems. The module's isolated baseplate simplifies thermal management in multi-device assemblies, making it a preferred building block for OEM drive manufacturers and system integrators operating in steel, chemical, plastics, and material processing industries.

Quick Reference: SKKT25/14

Key Features of the SKKT25/14:

• 1400V VDRM/VRRM blocking voltage with high dV/dt immunity for robust operation in noisy industrial environments
• 25A average on-state current with low on-state voltage drop (VT), minimizing conduction losses in continuous-duty applications
• Dual SCR topology in a single package supports common-cathode bridge leg configurations, reducing component count and assembly complexity
• Electrically isolated copper baseplate (2500V RMS isolation) enables direct mounting to system heatsinks without additional insulation hardware
• Defined gate trigger current (IGT) and holding current (IH) parameters ensure predictable firing behavior across temperature ranges
• Compatible with standard SKKT footprint, allowing drop-in replacement of like-rated modules from earlier production runs

The SKKT25/14 carries a factory lead time of approximately 37 weeks for new production orders, a timeline that can critically impact equipment uptime, repair schedules, and capital project deadlines. SEMIKRON's SCR modules in this voltage class have seen extended lead times driven by raw material constraints and consolidated fab capacity. Procurement teams managing MRO inventory or commissioning replacement drives should plan well ahead or engage a specialist distributor capable of locating existing stock from secondary market and authorized surplus channels to bridge the gap.
