The SEMIKRON SKR240/16 is a single thyristor (SCR) power module rated for 240A average on-state current and a 1600V repetitive peak off-state voltage (VDRM/VRRM). Designed for phase-controlled rectification, soft-start circuits, and AC power regulation, this module leverages SEMIKRON's robust ceramic substrate and pressure-contact construction to deliver stable thermal performance and high surge current capability. Its compact module format simplifies heatsink integration and reduces assembly complexity in high-power industrial drive and conversion equipment.

The SKR240/16 is well-suited for heavy industrial applications including DC motor drives, crane and hoist controls, excitation systems for generators and synchronous machines, electrochemical processing equipment, resistance welding controllers, and UPS input stage rectifiers. Its 1600V voltage class provides adequate margin for 690VAC three-phase line voltages when used in fully controlled bridge topologies. Engineers specifying equipment for steel mills, mining, marine propulsion, and utility infrastructure regularly rely on this voltage and current class of thyristor module for long-term field reliability.

Key Features of the SKR240/16:

• 240A average on-state current (IT(AV)) with high repetitive surge current (ITSM) capability for robust fault tolerance
• 1600V VDRM/VRRM voltage rating — suitable for 690VAC three-phase fully controlled bridge rectifier topologies
• Low on-state voltage drop (VT) minimizes conduction losses in continuous-duty industrial cycles
• High dI/dt and dV/dt ratings support reliable triggering in phase-control gate drive circuits
• Isolated baseplate construction enables direct mounting to standard heatsink profiles without additional insulation
• SEMIKRON module housing provides mechanical protection and simplifies series/parallel configuration in multi-module converter assemblies

SEMIKRON thyristor modules in the SKR240 series carry factory lead times that frequently extend to 33 weeks or more for new production orders. For OEMs managing production schedules, operators facing unplanned equipment downtime, or procurement teams building safety stock, waiting on factory lead time is often not a viable option. ATI Accurate Technology specializes in exactly this scenario — actively sourcing long lead time, allocated, and discontinued SEMIKRON power semiconductors through established distributor and surplus channels to close the gap between need and availability.

ATI Accurate Technology is headquartered in Palmetto, Florida, and ships same-day on orders placed before 5PM EST. We support maintenance engineers and procurement professionals with competitive pricing, volume discounts, and responsive service on hard-to-find IGBT modules, thyristors, diodes, and rectifier modules.
