The SEMIKRON SKN26/08UNF is a single-phase thyristor (SCR) module designed for demanding industrial power control applications. Rated at 26A average on-state current and an 800V repetitive peak off-state voltage (VDRM/VRRM), this module is housed in SEMIKRON's compact, industry-standard SKN package featuring isolated baseplate mounting for efficient heat dissipation. Its gate-triggered turn-on characteristics and robust blocking capability make it a dependable choice where precise phase control, soft-start, or controlled rectification is required in high-reliability environments.

The SKN26/08UNF is widely deployed in industrial AC motor soft starters, variable speed drives, resistance welding controllers, DC power supplies, heating element controls, and regenerative braking systems. Its consistent triggering threshold and low forward voltage drop support stable operation across a broad temperature range, making it suitable for continuous-duty cycles in manufacturing automation, material handling, HVAC drive systems, crane and hoist controls, and other process equipment where thyristor phase control is the architecture of choice.

Quick Reference: SKN26/08UNF

Key Features of the SKN26/08UNF:

• 800V VDRM/VRRM repetitive peak blocking voltage with high dV/dt immunity for robust operation on noisy industrial line supplies
• 26A average on-state current rating with low forward voltage drop (VT), minimizing conduction losses and heatsink thermal load
• Isolated copper baseplate construction enables direct mounting to standard heatsinks without additional insulation hardware
• Gate trigger current (IGT) and holding current (IH) parameters optimized for compatibility with standard SCR gate driver circuits and firing boards
• High surge current capability (ITSM) supports inrush and fault-condition robustness in motor drive and power supply applications
• Compact SKN footprint allows drop-in replacement in existing panel layouts with minimal rework or mechanical modification

The SKN26/08UNF carries a factory lead time of approximately 99 weeks for new production from SEMIKRON, placing it firmly in the long lead time category that can halt maintenance schedules and new build programs alike. Procurement engineers managing MRO inventories, OEM production lines, or legacy system refurbishments must plan well ahead or source through distributors with pipeline access. ATI Accurate Technology actively tracks availability across authorized and independent supply channels to help customers close gaps when factory timelines are not an option and downtime is not acceptable.

ATI Accurate Technology is located in Palmetto, Florida, and specializes in IGBTs, thyristors, diodes, and rectifier modules — including hard-to-find, obsolete, and long lead time parts like the SKN26/08UNF.
