The SEMIKRON SKKT26B/16E is a dual thyristor (SCR) module delivering 26A average on-state current (IT(AV)) and a 1600V repetitive peak off-state voltage (VDRM/VRRM). Built in SEMIKRON's industry-standard SKKT package, this module integrates two SCR elements in a common isolated baseplate configuration, simplifying layout in controlled rectifier bridges and AC power controllers. The low-profile package supports direct heatsink mounting and is optimized for phase-control switching frequencies typical of industrial drive front-ends, resistance heating regulators, and motor soft-start assemblies operating on high-voltage distribution lines.

The SKKT26B/16E is a proven choice across demanding industrial sectors. Variable-speed DC drives rely on thyristor modules like this for front-end controlled rectification, enabling precise armature voltage regulation. Resistance and induction heating systems use phase-angle control with SKKT-series devices to manage load power continuously. Soft-starters for three-phase AC motors incorporate dual SCR modules for smooth ramp-up and ramp-down, reducing mechanical stress and inrush current. Uninterruptible power supplies, battery chargers, crane and hoist drives, and industrial power conversion equipment also utilize 1600V-class thyristor modules where robust blocking voltage margin is essential for reliable long-term operation.

Key Features of the SKKT26B/16E:

• Dual SCR topology in a single SKKT package simplifies controlled rectifier bridge assembly and reduces PCB or busbar footprint
• 1600V VDRM/VRRM blocking voltage provides substantial margin for line transients on 480V–690V three-phase distribution systems
• 26A IT(AV) per thyristor element rated for continuous phase-control duty in resistive and inductive load applications
• Isolated copper baseplate construction enables direct heatsink mounting with standard thermal interface materials for optimized thermal management
• Low gate trigger current and voltage requirements ensure compatibility with standard SCR gate driver and firing card circuits
• SEMIKRON SKKT package footprint is industry-standardized, allowing form-fit-function interchangeability with equivalent modules from the SKKT series lineup

The SKKT26B/16E carries a current factory lead time of approximately 43 weeks for new production from SEMIKRON, which presents a significant challenge for maintenance teams managing unplanned equipment failures or procurement teams building safety stock. SEMIKRON's SKKT-series thyristor modules are embedded in a wide base of installed industrial equipment, meaning supply disruptions translate directly into costly downtime. ATI Accurate Technology specializes in sourcing long-lead-time, hard-to-find, and legacy SEMIKRON power semiconductor modules, working through established supply channels to locate inventory when standard distribution cannot deliver.
