The Semikron SKKT26/16E is a dual thyristor (SCR) module delivering 26A average on-state current and a 1600V repetitive peak off-state voltage (V_DRM/V_RRM). Built in Semikron's established SKKT package, it features an isolated copper base plate for direct heatsink mounting, low thermal resistance, and industry-standard gate triggering characteristics. This module is engineered for continuous operation in line-frequency power conversion circuits where high blocking voltage and rugged thermal performance are critical to system reliability and longevity.

The SKKT26/16E is widely deployed in industrial AC motor soft starters, phase-controlled rectifiers, AC power regulators, resistance welding controllers, and three-phase converter front ends in variable speed drives. Its isolated base plate construction makes it suitable for multi-module heatsink assemblies in compact drive cabinets. Engineers specify this device in heating control systems, crane and hoist drives, elevator controls, and UPS input stages where proven thyristor technology provides predictable, controllable power switching under heavy cyclic load conditions.

Key Features of the SKKT26/16E:

• 1600V repetitive peak off-state voltage provides robust blocking margin in 690V and 480V three-phase line applications
• 26A average on-state current (I_TAV) with low on-state voltage drop (V_T) minimizing conduction losses in continuous duty cycles
• Isolated copper base plate (V_isol 2500V RMS) enables direct mounting to heatsink without additional insulation hardware in most configurations
• Industry-standard SKKT package footprint ensures drop-in compatibility with existing PCB layouts and heatsink designs
• Gate trigger specifications compatible with standard SCR firing boards and phase control ICs used in legacy and modern drive platforms
• Low thermal resistance junction-to-case (R_thJC) supports high power density mounting in multi-module converter assemblies

With a factory lead time of 42 weeks for new production, the SKKT26/16E presents a real procurement challenge for maintenance teams managing unplanned downtime or engineers designing equipment with firm delivery schedules. Semikron's SKKT-series modules are embedded in legacy industrial equipment worldwide, and sourcing genuine replacement stock requires a distributor with active supply chain relationships. ATI Accurate Technology specializes in exactly these situations — long lead time, hard-to-find, and production-discontinued power semiconductors where standard distribution channels fall short.

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