The SEMIKRON SKKT213/10D is a high-current dual thyristor (SCR) module housed in the industry-standard SKKT package, rated for 213A average on-state current and a 100V repetitive peak blocking voltage (VRRM/VDRM). Designed for phase-controlled rectification and AC power regulation, this module integrates two SCR die with isolated baseplate mounting, simplifying heatsink assembly in high-density power converter designs. Its robust construction and well-established gate trigger characteristics make it a preferred choice where repeatable, stable switching performance is critical in three-phase and single-phase bridge topologies.

The SKKT213/10D is widely deployed across heavy industrial applications including DC motor drives, soft starters, crane and hoist controls, induction heating systems, electrochemical rectifiers, and uninterruptible power supplies (UPS). It is equally at home in welding equipment power stages, battery charging systems, and industrial furnace temperature controllers. Wherever controlled rectification of medium-to-high current loads is required — and where proven thyristor technology offers the reliability and simplicity advantages over newer switching topologies — the SKKT213/10D remains a go-to module for OEM builders and field maintenance teams alike.

Quick Reference: SKKT213/10D

Key Features of the SKKT213/10D:

• Dual SCR (thyristor) configuration in a single isolated-baseplate SKKT package, enabling compact B2 or B6 bridge circuit assembly with minimal external hardware
• 213A average on-state current (IT(AV)) with low on-state voltage drop, reducing conduction losses in continuous high-current rectifier duty cycles
• 100V VRRM/VDRM repetitive peak blocking voltage with high dV/dt immunity, supporting stable operation on regulated industrial supply rails
• Electrically isolated AlO₂ ceramic baseplate provides dielectric isolation between the power terminals and heatsink, simplifying mechanical integration and reducing system-level EMI coupling
• Gate trigger parameters optimized for straightforward firing circuit design; compatible with standard SCR gate driver ICs and pulse transformer triggering schemes
• Manufactured to SEMIKRON's established quality standards, offering consistent lot-to-lot parameter matching critical for paralleling applications and long-term field reliability

With a current factory lead time of 43 weeks for new production, the SKKT213/10D presents a genuine sourcing challenge for maintenance teams dealing with equipment downtime or procurement teams managing build schedules. SEMIKRON thyristor modules in the SKKT series are considered long-lead-time components, and spot availability on the open market is inconsistent. ATI Accurate Technology actively maintains sourcing networks for exactly these situations — hard-to-find, long-lead, and obsolete power semiconductors. Reaching out early in your planning cycle is strongly recommended to avoid schedule delays or unplanned outages waiting on factory lead times.

ATI Accurate Technology is based in Palmetto, Florida and stocked to support engineers and procurement teams who cannot afford to wait. We offer same-day shipping on orders placed before 5PM EST, genuine OEM parts, and volume pricing for larger quantity requirements.
