The Mitsubishi PS21962-4 is an Intelligent Power Module combining IGBT power switches with integrated gate drive circuitry, bootstrap power supply, and on-chip protection functions including overcurrent, short-circuit, and undervoltage lockout. This level of integration reduces external component count, shrinks board space, and accelerates design cycles for engineers building compact, high-reliability inverter systems. The module is engineered for demanding industrial and commercial environments where thermal performance and switching precision are non-negotiable requirements.

The PS21962-4 is well-suited for three-phase variable-frequency drives (VFDs), HVAC inverter compressors, servo drive amplifiers, uninterruptible power supplies (UPS), and solar inverter platforms. Its integrated protection architecture makes it a strong choice for OEM equipment manufacturers and field replacement applications where minimizing downtime is paramount. Industrial automation platforms, pump and fan controls, and light traction systems also benefit from the module's combination of high-side and low-side gate drive integration in a thermally optimized package.

Key Features of the PS21962-4:

• Integrated IGBT power stage with on-chip high- and low-side gate drive circuitry, eliminating the need for discrete gate driver ICs
• Built-in protection functions including overcurrent (OC), short-circuit (SC), and undervoltage lockout (UVLO) on both high- and low-side channels
• Bootstrap power supply circuit integrated within the module, reducing external power supply complexity for the high-side drive stage
• Fault output signal pin enables system-level fault monitoring and coordinated shutdown logic in the host controller
• Optimized IGBT switching characteristics reduce EMI generation and switching losses in PWM-controlled inverter topologies
• Compact, thermally efficient package construction supports direct heatsink mounting for high-density drive system assemblies

The PS21962-4 carries a factory lead time of 99 weeks from Mitsubishi — a reality that continues to challenge procurement teams across the motor drive, HVAC, and industrial automation sectors. Whether you're managing a production line stocking strategy, executing an emergency board-level repair, or qualifying inventory for a long-running OEM platform, waiting nearly two years for new production simply isn't viable. ATI maintains stock of hard-to-find and long-lead-time Mitsubishi IPMs specifically to bridge that gap for engineers and buyers who can't afford schedule risk on critical power components.
