The Mitsubishi PS22A76 is a 22A Intelligent Power Module (IPM) designed to simplify inverter circuit design by integrating IGBT chips, gate drive circuitry, and comprehensive protection functions into a single, thermally optimized package. This level of integration reduces PCB footprint, minimizes external component count, and improves system reliability by eliminating discrete gate drive design variables. The onboard protection logic guards against overcurrent, short circuit, undervoltage lockout, and overtemperature conditions, making the PS22A76 a dependable solution for demanding power conversion applications where uptime is critical.

The PS22A76 is widely deployed in three-phase AC motor drives, variable frequency drives (VFDs), HVAC compressor inverters, industrial pump and fan controls, and light industrial servo systems. Its compact IPM architecture is particularly valued in equipment where board space is constrained and where integrating discrete IGBT arrays with separate gate drivers would introduce unacceptable complexity or risk. OEMs and service organizations supporting legacy inverter platforms rely on this module to maintain uptime in fielded equipment across manufacturing, building automation, and process control environments.

Quick Reference: PS22A76

Key Features of the PS22A76:

• Integrated six-pack IGBT inverter bridge with onboard gate drive circuitry, reducing external component requirements and simplifying PCB layout
• Built-in protection functions including overcurrent (OC), short-circuit (SC), undervoltage lockout (UVLO), and overtemperature (OT) shutdown with fault output signal
• 22A continuous output current rating optimized for sub-fractional to fractional horsepower three-phase motor drive applications
• Isolated, transfer-molded package construction providing enhanced thermal performance and mechanical durability in industrial environments
• Compatible with standard microcontroller and DSP-based PWM inverter control schemes, easing integration into existing drive platform designs
• Low-loss IGBT chip technology contributing to reduced switching and conduction losses, improving overall inverter efficiency

The PS22A76 carries a factory lead time of 99 weeks through standard Mitsubishi distribution channels, placing it firmly in the category of long-lead-time and effectively allocation-constrained components. For engineers tasked with repairing fielded equipment or procurement teams managing MRO and spare parts inventories, waiting nearly two years for factory production is not a viable option. ATI specializes in exactly this scenario — sourcing and stocking hard-to-find, long-lead-time, and discontinued power semiconductors so that production lines and critical systems do not sit idle waiting on new factory runs.

ATI Accurate Technology is a power semiconductor distributor based in Palmetto, Florida, stocking IGBTs, IPMs, thyristors, diodes, and rectifier modules including obsolete and long-lead-time parts like the PS22A76.
