The PS21864-AP is a 600V, 20A Mitsubishi Electric Intelligent Power Module (IPM) from the DIPIPM series, combining a fully integrated 3-phase IGBT inverter bridge with onboard gate drive ICs, bootstrap power supply circuitry, and comprehensive protection functions including over-current, short-circuit, under-voltage lockout, and over-temperature shutdown. The monolithic integration of drive and protection logic reduces external component count, simplifies PCB layout, and accelerates time-to-market for inverter designers working within tight form-factor constraints. It is an industry-standard solution for low-to-mid power motor control platforms.

The PS21864-AP is widely deployed in variable-frequency drives (VFDs), HVAC fan and pump controllers, air conditioner compressor inverters, small servo drives, and general-purpose industrial motor control equipment. Its compact DIP-style package and self-contained protection architecture make it a preferred choice for OEM appliance inverter boards and industrial automation platforms where board space, thermal management, and reliability are critical design priorities. Replacement demand is consistently high across HVAC, industrial machinery, and consumer inverter markets.

Key Features of the PS21864-AP-MITSUBISHI:

• 600V / 20A 3-phase IGBT inverter bridge in a compact DIPIPM package suitable for space-constrained PCB designs
• Integrated gate drive circuitry with bootstrap power supply eliminates the need for isolated gate drive power supplies on the high-side switches
• Built-in protection: over-current (OC), short-circuit (SC), under-voltage lockout (UVLO), and over-temperature (OT) with fault output signal to the control MCU
• Low-loss IGBT chip technology optimized for PWM switching frequencies up to 20kHz, reducing audible noise in motor drive applications
• Single-supply operation from a 15V gate drive rail simplifies power supply design in cost-sensitive inverter platforms
• Thermistor output pin for real-time junction temperature monitoring and thermal derating by the system controller

The PS21864-AP has reached mature and declining production status, making reliable sourcing increasingly difficult through standard distribution channels. Lead times from broadline distributors frequently extend 26–52 weeks, and counterfeit risk in the spot market is a genuine concern for procurement teams. ATI Accurate Technology maintains verified stock of genuine Mitsubishi IPM modules specifically to serve engineers and buyers who cannot afford extended downtime or unplanned redesigns. Our inventory is traceable, inspected, and ready to deploy.
