The SEMIKRON SKKT105/16E is a dual SCR thyristor module configured in a common-cathode or inverse-parallel arrangement, rated for 105A average on-state current (I_TAV) and a 1600V repetitive peak off-state voltage (V_DRM/V_RRM). Housed in SEMIKRON's proven SKKT power package, this module integrates two thyristors with isolated baseplate construction, enabling straightforward heatsink mounting and reliable thermal management. It is engineered for continuous operation in high-power industrial environments where gate controllability, surge current handling, and thermal cycling endurance are critical design requirements.

The SKKT105/16E is widely deployed in three-phase controlled rectifier bridges, DC motor drive front ends, soft-start units, AC power controllers, and UPS input stages across industries including metals processing, mining, oil and gas, marine propulsion, and heavy industrial automation. Its 1600V voltage class provides the necessary margin for line transients common in medium-voltage distribution environments. OEM equipment manufacturers and MRO facilities maintaining legacy drive systems regularly specify this module as a direct replacement in SEMIKRON-based power stacks that have remained in continuous service for decades.

Quick Reference: SKKT105/16E

Key Features of the SKKT105/16E:

• 105A average on-state current (I_TAV) with high surge current (I_TSM) capability for robust overcurrent resilience
• 1600V V_DRM/V_RRM voltage rating providing protective margin against line-side transients in medium-voltage systems
• Isolated copper baseplate construction for low thermal resistance (R_th(c-s)) and direct heatsink mounting without additional isolation hardware
• Low gate trigger current (I_GT) and voltage (V_GT) specifications enabling reliable firing from standard gate drive circuits
• SEMIKRON SKKT package format offering drop-in dimensional compatibility with existing SKKT-series designs and legacy power stacks
• Designed for repetitive blocking and high di/dt turn-on conditions typical of phase-controlled rectifier and cycloconverter topologies

The SKKT105/16E carries a factory lead time of approximately 34 weeks for new production orders — a timeline that can halt maintenance schedules and stall capital equipment commissioning. SEMIKRON thyristor modules at this voltage and current class are frequently required as emergency replacements in aging industrial drives and rectifier systems where no local inventory exists. ATI Accurate Technology specializes in bridging exactly this gap, actively sourcing long-lead-time and hard-to-find SEMIKRON power modules to support procurement teams and maintenance engineers who cannot wait out standard factory queues.

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