The Mitsubishi PM400DVA060 is a 400A, 600V Intelligent Power Module combining IGBT chips, gate drive circuitry, and onboard fault protection into a single, thermally optimized package. As part of Mitsubishi's DVA-series IPM family, this module was engineered to reduce external component count while delivering deterministic switching behavior and integrated protection functions including overcurrent, short-circuit, and temperature shutdown. Its self-contained architecture made it a preferred solution for engineers designing high-power inverter stages where board space, switching losses, and system reliability were primary constraints.

The PM400DVA060 was widely deployed in industrial variable-frequency drives (VFDs), servo amplifiers, regenerative AC drive systems, elevator traction controls, and large UPS inverter stages. Its current and voltage ratings placed it squarely in mid-to-heavy industrial applications where robust motor control and reliable fault response were non-negotiable. Facilities running legacy CNC machinery, industrial HVAC systems, crane drives, and automated manufacturing equipment frequently depend on this exact module to maintain uptime in installed platforms that cannot be easily redesigned around modern replacement parts.

Key Features of the PM400DVA060:

• 400A continuous collector current with 600V blocking voltage, suited for high-power three-phase inverter topologies
• Integrated gate drive circuitry eliminates the need for external isolated gate drivers, simplifying PCB layout and reducing BOM complexity
• Onboard overcurrent and short-circuit protection with fault output signal for system-level fault management
• Integrated temperature monitoring and over-temperature shutdown to protect against thermal runaway in demanding duty cycles
• Low switching losses through optimized IGBT chip design, supporting efficient PWM operation in motor drive and inverter applications
• Industry-standard module footprint compatible with established heatsink and mounting configurations used in legacy drive platforms

The PM400DVA060 has been discontinued by Mitsubishi Electric with no scheduled return to production, making factory procurement impossible through standard distribution channels. For maintenance engineers supporting installed VFD systems, servo drives, or industrial inverters built around this module, sourcing from the secondary market is the only viable path to keeping equipment operational. Attempting to redesign around a modern equivalent IPM involves significant engineering effort, firmware changes, and requalification — costs that far exceed sourcing an original replacement. Identifying a reliable supplier with verified new OEM stock is critical to avoiding counterfeit risk and extended downtime.
