The SEMIKRON SKKT162/14E is a dual thyristor (SCR) module in the SEMIPACK package format, rated for 162A average on-state current (IT(AV)) and a 1400V repetitive peak off-state voltage (VDRM/VRRM). Designed for phase-control rectification and AC power regulation, this module integrates two SCR elements in a common isolated base, simplifying heatsink mounting and reducing system wiring complexity. Its robust construction and well-characterized gate trigger parameters make it a reliable choice for engineers designing or maintaining high-power industrial converter systems where thermal performance and long service life are critical.

The SKKT162/14E is widely used in industrial DC motor drives, soft starters, resistance heating controllers, crane and hoist drives, and field excitation systems for large AC machines. Its 1400V voltage class makes it well-suited for 690V AC line applications with adequate voltage margin, and the dual-SCR topology supports three-phase fully controlled bridge configurations with minimal additional components. Power conversion system integrators, OEM drive manufacturers, and MRO procurement teams rely on this module for both new build and retrofit applications across metals, mining, oil and gas, and heavy manufacturing sectors.

Key Features of the SKKT162/14E:

• Dual SCR (anti-parallel not included) configuration in isolated SEMIPACK baseplate package for simplified heatsink integration
• 1400V VDRM/VRRM voltage class providing robust margin on 690V AC three-phase power systems
• 162A average on-state current rating supporting high-power phase-controlled rectifier and AC controller designs
• Low thermal resistance junction-to-case (RthJC) enabling efficient heat dissipation in forced-air or liquid-cooled heatsink assemblies
• Industry-standard gate trigger characteristics compatible with established firing board and pulse transformer designs used in legacy and modern drive platforms
• Meets IEC and UL isolation voltage standards with electrically isolated copper baseplate for safe, reliable multi-module heatsink mounting

With a factory lead time of approximately 34 weeks for new production, the SKKT162/14E presents a real sourcing challenge for maintenance teams facing unplanned equipment failures or procurement professionals managing tight project schedules. SEMIKRON's SEMIPACK thyristor modules are widely embedded in legacy drive systems still in active service, making urgent replacement a common scenario. ATI Accurate Technology specializes in locating long-lead-time and hard-to-find power semiconductors through a broad network of verified distributor and OEM channels, helping customers avoid extended production downtime while new factory stock is on order.

ATI Accurate Technology is headquartered in Palmetto, Florida and ships same-day on orders placed before 5PM EST. Our team understands the urgency behind power semiconductor failures and is equipped to support both emergency single-unit needs and volume procurement programs.
