The SK15DGDL126ET is a SEMIKRON IGBT module combining a 1200V voltage class with a 15A current rating in a dual configuration optimized for high-frequency switching in industrial power conversion systems. Designed for efficiency and reliability under sustained thermal stress, this module integrates freewheeling diodes and advanced IGBT chip technology to minimize conduction and switching losses. Its compact footprint and standardized base plate dimensions simplify drop-in integration into existing converter designs, making it a preferred choice for engineers requiring proven performance in a thermally demanding environment.

The SK15DGDL126ET is well suited for a broad range of industrial applications including AC motor drives, servo amplifiers, UPS systems, induction heating equipment, and regenerative braking converters. Its 1200V voltage rating provides the necessary headroom for 690V AC bus architectures, while the 15A current capacity serves low-to-mid power drive stages. Renewable energy inverters, welding power supplies, and auxiliary power converters in rail traction systems also benefit from the switching characteristics and rugged construction this SEMIKRON module delivers.

Key Features of the SK15DGDL126ET:

• 1200V VCES blocking voltage with 15A rated continuous collector current for 690V bus compatibility
• Integrated freewheeling diodes per phase leg, eliminating external diode selection and reducing BOM complexity
• Low V_CE(sat) and optimized tail current characteristics reduce conduction and turn-off switching losses at operating frequencies up to 20kHz
• Isolated copper base plate construction ensures reliable thermal transfer to heatsink and meets IEC 60747 insulation requirements
• Industry-standard module footprint compatible with SEMIKRON and cross-reference equivalent housings for simplified retrofitting
• Designed for operation across a wide junction temperature range (T_j up to 150°C), supporting high-ambient industrial environments

With a factory lead time currently listed at 99 weeks, the SK15DGDL126ET represents a significant sourcing challenge for procurement teams managing production schedules or executing emergency maintenance replacements. SEMIKRON modules at this voltage and current class are frequently subject to extended manufacturing queues due to wafer allocation and substrate supply constraints. ATI Accurate Technology actively maintains distributor relationships and monitors secondary market channels to locate new OEM stock ahead of standard factory timelines, helping customers avoid costly line downtime while protecting warranty and quality standards.
