The Mitsubishi PS21765 is an Intelligent Power Module combining high-speed IGBT chips with integrated gate drive, fault protection, and bootstrap circuitry in a single molded package. This level of integration reduces external component count, simplifies PCB layout, and improves system reliability in demanding power conversion environments. Designed to operate across industrial temperature ranges, the PS21765 delivers consistent switching performance with built-in safeguards against overcurrent, short circuit, undervoltage lockout, and overtemperature conditions — making it a preferred solution for compact, high-reliability inverter designs.

The PS21765 is widely deployed in variable frequency drives (VFDs), AC servo amplifiers, uninterruptible power supplies, air conditioning compressor inverters, and general-purpose motor control systems. Its integrated protection and drive functions make it especially well-suited for space-constrained industrial equipment where discrete gate drive circuits would add cost and design complexity. OEMs and repair facilities working on HVAC systems, CNC machinery, elevator drives, and factory automation equipment regularly specify or replace this module in both new builds and field service applications.

Quick Reference: PS21765

Key Features of the PS21765:

• Integrated IGBT switching devices with monolithic gate drive IC eliminate need for external driver circuitry
• Built-in protection functions including overcurrent shutdown, short-circuit protection, undervoltage lockout (UVLO), and overtemperature detection
• Bootstrap power supply circuit simplifies high-side gate drive implementation without isolated power supplies
• Fault output signaling enables host controller monitoring for system-level fault response and diagnostics
• Low-loss IGBT chip technology supports high switching frequency operation while minimizing thermal stress
• Compact, standardized package footprint supports direct drop-in replacement in existing inverter board designs

With a factory lead time of 99 weeks on new production, the PS21765 presents a significant procurement challenge for maintenance operations, production line repairs, and OEM restocking. Extended lead times at this level effectively make the part functionally obsolete for any application requiring rapid turnaround. Facilities relying on Mitsubishi IPM-based drives cannot afford to wait nearly two years for a single critical component. ATI Accurate Technology maintains independent stock of hard-to-find and long-lead-time modules like the PS21765 specifically to bridge this gap and keep industrial equipment running without costly downtime.

ATI Accurate Technology is a power semiconductor distributor based in Palmetto, Florida, stocking IGBTs, thyristors, diodes, and intelligent power modules including obsolete and long-lead-time parts.
