The 91MT160KB is an IGBT module manufactured by International Rectifier (IR), a trusted name in power semiconductor engineering. Designed for demanding switching applications, this module delivers reliable performance in systems where thermal stability, switching efficiency, and compact power density are non-negotiable. With factory lead times for new production currently at 99 weeks, sourcing this part through authorized stocking distributors is the only practical option for most maintenance and procurement teams operating on real-world timelines.

The 91MT160KB is well suited for a broad range of industrial power electronics applications including motor drives, servo controllers, UPS systems, induction heating equipment, welding inverters, and industrial power supplies. Its IGBT module architecture makes it a reliable choice for engineers designing or maintaining systems that require consistent gate drive response, low conduction losses, and robust short-circuit performance under variable load conditions found in factory automation and heavy industrial environments.

Quick Reference: 91MT160KB

Key Features of the 91MT160KB:

• IGBT module construction from International Rectifier with proven gate charge and switching characteristics optimized for industrial inverter duty cycles
• Rated voltage architecture suitable for low-voltage bus applications requiring precise switching control and low on-state voltage drop
• Module packaging provides integrated isolation between the semiconductor die and heatsink mounting surface, simplifying thermal management design
• Optimized for pulse-width modulation (PWM) drive topologies common in variable frequency drives and servo amplifier stages
• Designed for compatibility with standard IR gate driver ICs and reference drive circuits, reducing retrofit and replacement complexity
• New OEM condition ensures full rated performance, traceability, and compatibility with original equipment specifications

With a factory lead time of 99 weeks on new production, the 91MT160KB represents exactly the type of long-lead-time, hard-to-find component that can halt production lines and delay critical projects. Whether you're dealing with an unplanned equipment failure, building safety stock for aging IR-based drive systems, or managing an MRO parts program for industrial machinery, waiting two years for factory delivery is not a viable option. ATI Accurate Technology maintains inventory of obsolete and long-lead IR components specifically to bridge this gap for maintenance engineers and procurement professionals who cannot afford extended downtime.
