The Infineon T218N1200TOC is a robust phase control thyristor power module delivering a continuous on-state current of 218A at a repetitive peak off-state voltage of 1200V. Built to Infineon's rigorous manufacturing standards, this module features an isolated baseplate construction suited for heatsink mounting, enabling reliable thermal management in high-power density assemblies. Its SCR-based topology makes it a proven solution wherever precise AC power control, current limiting, or controlled rectification is required in industrial-grade equipment.

The T218N1200TOC is widely deployed in AC motor soft starters, static VAR compensators, resistance heating controllers, excitation systems, and three-phase power converters found across steel mills, mining operations, petrochemical plants, water treatment facilities, and renewable energy installations. Maintenance engineers specifying replacement modules for legacy drive platforms frequently rely on this part to restore uptime quickly. Its voltage and current class also makes it common in UPS systems, traction power supplies, and medium-voltage industrial rectifier assemblies.

Quick Reference: T218N1200TOC

Key Features of the T218N1200TOC:

• 218A average on-state current (IT(AV)) with 1200V repetitive peak blocking voltage (VDRM/VRRM)
• Isolated copper baseplate for direct heatsink mounting, minimizing thermal resistance in high-power installations
• Phase control SCR topology optimized for line-frequency switching in AC power regulation and rectification circuits
• Low gate trigger current requirements enabling compatibility with standard thyristor firing boards and pulse transformers
• High surge current capability (ITSM) providing resilience against transient overloads common in motor starting and fault conditions
• Compact module footprint consistent with standard Infineon housing dimensions for drop-in replacement on existing heatsink assemblies

Infineon lists the T218N1200TOC at a factory lead time of 99 weeks for new production orders — a timeline that makes open-market stock the only realistic option for emergency repairs, scheduled shutdowns, or projects that cannot absorb a two-year procurement cycle. ATI Accurate Technology maintains inventory of hard-to-find and long-lead-time power semiconductors precisely for this scenario. Whether you are sourcing a single module for breakdown maintenance or building buffer stock for a fleet of drives, having a reliable distributor with confirmed on-hand inventory eliminates schedule risk entirely.

ATI Accurate Technology is headquartered in Palmetto, Florida and specializes in IGBTs, thyristors, diodes, and rectifier modules — including obsolete and long-lead-time parts.
