The SEMIKRON SKN130/18 is a single-phase thyristor module delivering 130A average on-state current (IT(AV)) and a 1800V repetitive peak reverse voltage (VRRM), housed in SEMIKRON's industry-standard SKN power module package. Designed for phase-control and soft-start applications, this module integrates a thyristor in a thermally efficient, electrically isolated base configuration. It features a pressure-mounted package for superior thermal contact with heatsinks, making it well-suited for continuous-duty industrial power circuits where reliability and thermal management are paramount.

The SKN130/18 is deployed across a broad spectrum of heavy industrial applications including AC motor soft starters, DC motor drives, crane and hoist controls, industrial heating systems, and electrochemical power supplies. Its high blocking voltage rating makes it especially valuable in medium-voltage drive architectures and utility-connected rectifier stages. The module is also found in uninterruptible power supplies (UPS), welding equipment, and field excitation systems where controlled rectification at elevated voltage levels is required.

Key Features of the SKN130/18:

• 1800V repetitive peak reverse voltage (VRRM) for high-voltage phase-control applications
• 130A average on-state current (IT(AV)) rating supports continuous heavy-duty industrial duty cycles
• Electrically isolated copper base plate ensures safe mounting to grounded heatsink assemblies without additional insulation hardware
• Low thermal resistance (Rth(j-c)) for efficient junction-to-case heat transfer, extending operational life under high-load conditions
• Stud or screw terminal design compatible with standard SKN footprint busbars and gate driver configurations
• Qualified to IEC and EN power module standards, consistent with SEMIKRON's established manufacturing quality controls

The SKN130/18 carries a factory lead time of 99 weeks for new production — nearly two years — making open-market inventory the only practical source for maintenance, repair, and retrofit projects that cannot tolerate extended downtime. Procurement teams managing aging drives, legacy rectifier banks, or long-running industrial installations should treat available stock as a strategic asset. ATI sources genuine OEM components through established distribution channels and maintains inventory of hard-to-find SEMIKRON thyristor modules specifically to support customers facing these long lead time constraints.
