The SEMIKRON SKKT105/14E is a dual SCR (thyristor) power module delivering 105A average on-state current and a 1400V repetitive peak off-state voltage (VDRM/VRRM). Housed in SEMIKRON's industry-standard SKKT package with an electrically isolated copper baseplate, this module supports reliable thermal management through direct heatsink mounting. The dual common-cathode or common-anode configuration makes it immediately applicable to three-phase bridge rectifier and AC phase-control topologies. Its rugged construction and well-documented gate characteristics make it a preferred choice in demanding industrial environments where thermal cycling and surge events are routine.

The SKKT105/14E is widely deployed across heavy industrial applications including AC variable speed drives, soft starters, DC motor field and armature controllers, resistance welding equipment, industrial heating systems, uninterruptible power supplies (UPS), and crane or hoist drive systems. Its 1400V voltage class provides the necessary headroom for 690VAC line-side connections, while the 105A current rating accommodates mid-range drive and converter designs. OEM capital equipment manufacturers and MRO maintenance teams in steel, mining, oil and gas, pulp and paper, and marine industries regularly rely on this module for both new builds and field replacements.

Key Features of the SKKT105/14E:

• 1400V repetitive peak off-state voltage (VDRM/VRRM) providing wide safety margin on 480V and 690VAC systems
• 105A average on-state current (IT(AV)) rated at case temperature TC = 85°C for reliable continuous-duty operation
• Electrically isolated copper baseplate enabling direct heatsink mounting without additional isolation hardware
• Industry-standard SKKT package footprint ensuring drop-in compatibility with existing SEMIKRON-designed power stacks and drive assemblies
• Low thermal resistance junction-to-case (Rthjc) supporting high power density converter designs with effective heat dissipation
• Compatible with standard phase-control gate drive circuits; well-characterized dV/dt and dI/dt ratings simplify snubber and gate resistor selection

The SKKT105/14E carries a 33-week factory lead time from SEMIKRON under current production schedules, placing it firmly in the long-lead-time category that routinely stalls maintenance repairs and new equipment builds. For facilities managing aging drives or capital projects with fixed commissioning deadlines, waiting eight-plus months for factory delivery is not a viable option. ATI Accurate Technology specializes in sourcing exactly these hard-to-find and extended-lead-time SEMIKRON thyristor modules through established distributor relationships and secondary market channels, providing engineers and procurement teams with faster access to verified new OEM components.
