The Infineon FS15R12YT3 is a 1200V, 15A IGBT module engineered for demanding power switching applications where efficiency, thermal stability, and compact packaging are critical. Built on Infineon's proven IGBT technology, this module integrates fast-recovery freewheeling diodes to reduce switching losses and simplify circuit design. Its robust construction makes it well suited for continuous-duty operation across a wide temperature range, meeting the performance expectations of engineers designing or maintaining precision power conversion equipment.

The FS15R12YT3 sees widespread deployment in industrial variable-speed motor drives, solar inverters, UPS systems, induction heating equipment, and auxiliary power supplies. Its 1200V blocking voltage and 15A current rating position it as a reliable choice for mid-power inverter legs, H-bridge configurations, and three-phase converter stages found in factory automation, HVAC drive systems, and renewable energy infrastructure. Maintenance teams servicing legacy drive platforms frequently require this module as a direct drop-in replacement to restore equipment to full operational capacity.

Key Features of the FS15R12YT3:

• 1200V collector-emitter breakdown voltage (VCES) for high-voltage bus compatibility in industrial inverter topologies
• 15A continuous collector current rating with integrated fast-recovery anti-parallel freewheeling diodes
• Low VCE(sat) characteristics reduce on-state conduction losses, improving overall converter efficiency
• Optimized gate charge and switching speed balance between low switching losses and EMI performance in PWM applications
• Isolated baseplate construction supports standard heatsink mounting and simplifies thermal management in multi-module assemblies
• Wide operating junction temperature range (Tj) suitable for sustained industrial duty cycles and high-ambient installations

With a current factory lead time of 99 weeks, sourcing the FS15R12YT3 through standard distribution channels can bring production lines and critical equipment to a standstill. For maintenance engineers facing an unplanned failure or procurement teams building safety stock, waiting nearly two years is not an option. ATI Accurate Technology specializes in exactly this scenario — stocking hard-to-find, long-lead-time, and obsolete power semiconductors so that a 99-week manufacturer queue never becomes your problem. Our inventory is verified new OEM product, not gray-market or reconditioned stock.

ATI Accurate Technology is located in Palmetto, Florida, and ships same-day on orders placed before 5PM EST. Whether you need a single replacement module or volume quantities for a stocking program, our team is ready to help.
