The Semikron SKKT26/16D is a dual SCR (thyristor) power module delivering 26A average on-state current and a 1600V repetitive peak off-state voltage (VDRM/VRRM). Built on Semikron's proven SKKT platform, this module houses two thyristors in an industry-standard isolated base package, enabling straightforward heatsink integration without additional isolation hardware. Its robust silicon construction and reliable gate triggering characteristics make it a dependable solution for phase-control and AC switching topologies operating in high-voltage industrial environments where thermal stability and voltage blocking performance are critical.

The SKKT26/16D is well suited for a broad range of industrial power electronics applications including AC motor soft starters, DC drive converters, resistance welding controllers, heating element regulators, and UPS rectifier stages. Its dual-thyristor topology supports anti-parallel or series circuit configurations used in full-wave phase-control and bidirectional AC switching designs. Power supply OEMs, crane and hoist drive manufacturers, and industrial process heating system integrators rely on Semikron SKKT-series modules for their long service life, consistent triggering sensitivity, and compatibility with standard SKKT footprint heatsink assemblies.

Quick Reference: SKKT26/16D

Key Features of the SKKT26/16D:

• Dual thyristor configuration in a single isolated base module — reduces component count and simplifies PCB and busbar layout
• 1600V VDRM/VRRM blocking voltage provides substantial margin for 690V and higher AC line applications
• 26A IT(AV) rating suitable for medium-power phase-control circuits with appropriate heatsinking
• Industry-standard SKKT package footprint ensures drop-in compatibility with existing Semikron heatsink assemblies and mounting hardware
• Low gate trigger current (IGT) and well-defined holding current (IH) specifications enable reliable triggering from standard gate drive circuits
• Isolated copper base plate facilitates direct heatsink mounting without additional insulating pads, reducing thermal resistance in the assembly

The SKKT26/16D carries a factory lead time of approximately 41 weeks for new production, placing it firmly in the long-lead-time category that can stall critical maintenance and production schedules. Semikron SKKT-series modules of this voltage class are frequently encountered in aging industrial drives, welding equipment, and rectifier systems where replacement demand is unpredictable. ATI Accurate Technology actively sources new OEM stock of hard-to-find and extended-lead Semikron modules, giving maintenance teams and procurement professionals an alternative channel when factory direct timelines are unacceptable. Contact ATI early to check current inventory positions and avoid costly downtime.

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