The SEMIKRON SKKT41/14E is a dual thyristor (SCR) module configured in a common cathode arrangement, rated for 41A average on-state current (IT(AV)) and a 1400V repetitive peak off-state voltage (VDRM/VRRM). Housed in SEMIKRON's industry-standard SEMIPACK 1 package, this module features an isolated copper base plate for efficient heat dissipation to a heatsink. It is designed for phase-controlled rectification, soft-start circuits, and AC power regulation in high-reliability industrial power conversion systems.

The SKKT41/14E is well suited for a broad range of industrial applications including DC motor drives, crane and hoist control systems, battery chargers, UPS systems, electrochemical processing equipment, and heating control. Its robust SEMIPACK construction makes it a preferred choice for OEM equipment builders and MRO replacement in legacy drives and power controllers where consistent gate trigger sensitivity and low thermal resistance are critical to uptime and system reliability.

Key Features of the SKKT41/14E:

• Dual SCR common cathode configuration in SEMIPACK 1 package — drop-in compatible with standard SEMIKRON SKKT footprints
• 1400V VDRM/VRRM repetitive peak off-state voltage for operation on 690VAC line voltages with adequate safety margin
• 41A average on-state current (IT(AV)) per thyristor with a low on-state voltage drop (VT) for reduced conduction losses
• Isolated copper base plate with Al2O3 DCB substrate providing low junction-to-case thermal resistance (Rthjc) for effective heatsink cooling
• Defined gate trigger current (IGT) and holding current (IH) parameters ensuring reliable firing with standard thyristor gate drive circuits
• High dv/dt and di/dt ratings supporting use in snubber-assisted phase control and soft-switching topologies

The SKKT41/14E carries a factory lead time of 36 weeks for new production, placing it firmly in the long lead time category that challenges maintenance schedules and MRO procurement alike. SEMIKRON thyristor modules in the SEMIPACK series are widely embedded in legacy motor drive platforms and industrial controllers that remain in active service well beyond standard product lifecycles. When production queues stretch into months, unplanned downtime becomes a real financial risk. ATI Accurate Technology actively sources and stocks hard-to-find SEMIKRON modules, helping engineers and buyers bridge the gap between factory lead times and operational urgency.

ATI Accurate Technology is headquartered in Palmetto, Florida, and stocks a deep inventory of SEMIKRON thyristor modules, IGBTs, diodes, and rectifier assemblies.
