The SEMIKRON SKKT72/16E is a dual SCR (thyristor) module configured in a common cathode arrangement, rated for 72A average on-state current (IT(AV)) and a 1600V repetitive peak off-state voltage (VDRM/VRRM). Built in SEMIKRON's proven SEMIPACK 2 package, this module integrates two thyristors in a single isolated baseplate assembly, reducing component count and simplifying thermal management. It is optimized for use in phase-controlled rectifier bridges, soft-starters, and regulated AC-DC power supplies where high blocking voltage and reliable gate triggering are essential.

The SKKT72/16E is widely deployed in industrial AC motor drives, DC motor field and armature controllers, crane and hoist drive systems, resistance welding equipment, and uninterruptible power supply (UPS) front-end rectifiers. Its high voltage rating makes it particularly well-suited for 690V three-phase input systems, and its robust package construction handles the thermal cycling demands of continuous industrial duty cycles. Power electronics engineers also specify this module in battery formation equipment, electrochemical processing systems, and marine drive applications where controlled rectification at elevated voltages is required.

Key Features of the SKKT72/16E:

• Dual thyristor common cathode configuration in a single SEMIPACK 2 isolated baseplate package
• 1600V VDRM/VRRM blocking voltage rating — suitable for 690V three-phase line input applications
• 72A average on-state current (IT(AV)) with low on-state voltage drop for efficient thermal management
• Electrically isolated copper baseplate enables direct mounting to heatsink without additional isolation hardware
• High dI/dt and dV/dt capability supporting phase-controlled and force-commutated converter topologies
• Gate trigger current (IGT) and holding current (IH) parameters optimized for standard SCR gate driver circuits

The SKKT72/16E carries a factory lead time of approximately 26 weeks for new production orders, a timeline common across SEMIKRON's SEMIPACK series as global semiconductor supply chains continue to face capacity constraints. For OEMs managing production schedules, repair depots maintaining aging industrial drives, or procurement teams facing unexpected equipment failures, waiting six months for factory delivery is rarely an option. ATI Accurate Technology actively tracks availability across authorized distribution and secondary market channels to help customers locate genuine SEMIKRON product faster than standard lead times allow.

ATI Accurate Technology is a power semiconductor specialist based in Palmetto, Florida, stocking IGBTs, thyristors, diodes, and rectifier modules including long lead time and hard-to-find parts.
