The Mitsubishi PM25RKK120 is a 25A, 1200V Intelligent Power Module (IPM) combining high-speed IGBT chips with integrated gate drive circuitry and on-chip protection functions including overcurrent, short-circuit, undervoltage lockout, and overtemperature detection. This level of integration significantly reduces external component count and simplifies PCB layout in demanding power conversion designs. The PM25RKK120 is engineered for switching frequencies common in variable-speed drive applications and delivers low switching and conduction losses consistent with Mitsubishi's DIPIPM platform architecture.

The PM25RKK120 sees widespread deployment in industrial variable-frequency drives (VFDs), CNC machine tool servo amplifiers, HVAC inverter compressors, elevator drive systems, and general-purpose AC motor controllers operating at medium power levels. Its integrated protection suite makes it a preferred choice for OEM equipment designers and field retrofit engineers alike, particularly where board space is constrained and system reliability under fault conditions is non-negotiable. The module is also found in uninterruptible power supplies and renewable energy micro-inverter platforms.

Quick Reference: PM25RKK120

Key Features of the PM25RKK120:

• 1200V / 25A IGBT-based Intelligent Power Module with integrated 3-phase inverter topology
• Built-in gate drive circuitry eliminates the need for discrete isolated gate drivers per switch
• On-chip protection: overcurrent (OC), short-circuit (SC), undervoltage lockout (UVLO), and overtemperature (OT) with fault output signal
• Low thermal resistance junction-to-case supports high switching frequencies with adequate heatsinking
• Compatible with Mitsubishi DIPIPM application circuit references, simplifying design-in and field replacement
• Single-sided cooling package with industry-standard footprint for direct interchangeability in existing drive platforms

With a current factory lead time of 33 weeks on new production, procurement teams relying solely on direct factory orders face serious exposure to line stoppages and delayed field repairs. The PM25RKK120 has also reached end-of-life or allocation status across multiple distribution channels, making spot availability increasingly scarce. For maintenance operations running Mitsubishi-based drives or OEMs managing service parts inventory, securing stock from a specialist distributor with verified new OEM inventory is the practical path to avoiding extended downtime and missed production schedules.

ATI Accurate Technology, based in Palmetto, FL, stocks the PM25RKK120 as new OEM product and ships same-day on orders placed before 5PM EST. We specialize in IGBTs, IPMs, thyristors, and power modules — including obsolete and long-lead-time parts — and offer volume pricing for MRO and OEM procurement programs.
