PS21564-SP68AT4 600V 15A IGBT IPM

The Mitsubishi Electric  Superway PS21564-SP68AT4 600V 15A IGBT IPM is a high-voltage, three-phase Intelligent Power Module (IPM) designed for inverter-based motor-control and power-conversion applications. The PS21564-SP family is a compact DIP-IPM solution that integrates the main power semiconductor devices and associated drive and protection circuitry into a single module, helping simplify inverter system design and reduce the number of external components required.

The base PS21564-SP is specified as a 600V, 15A three-phase IGBT Intelligent Power Module. The module is designed around a three-phase DC-to-AC inverter bridge and is intended for small-power motor-control applications. The available technical documentation specifies a 600V collector-emitter voltage (VCES) and 15A collector current (±IC) per IGBT at a case temperature of 25°C. A peak collector current of 30A is specified for pulses shorter than 1ms under the stated conditions.

The module incorporates a six-IGBT three-phase inverter configuration with integrated free-wheeling diode (FWD) chips. Superway PS21564-SP68AT4 600V 15A IGBT IPM This configuration allows the device to convert a DC bus voltage into controlled three-phase AC output for driving suitable motors. By integrating the power switches and drive circuitry into a single module, the PS21564-SP family provides a compact solution for inverter designs where space, assembly simplicity, and integrated protection are important.

The PS21564-SP 600V 15A IPM is designed for use in low-power motor inverter applications. Mitsubishi’s DIP-IPM documentation identifies applications such as household air conditioners, washing machines, refrigerators, and other low-power industrial motor drives. Superway PS21564-SP68AT4 600V 15A IGBT IPM The module can be used in systems where a three-phase motor requires controlled variable-frequency or variable-speed operation.

One of the primary advantages of an Intelligent Power Module is the integration of gate-drive circuits with the power semiconductor devices. The PS21564-SP series incorporates high-side and low-side gate-drive functionality for the three-phase inverter bridge. This reduces the complexity of designing separate driver circuits for each IGBT and helps simplify the overall PCB design.

The module also incorporates protection functions intended to improve system reliability. Superway PS21564-SP68AT4 600V 15A IGBT IPM The technical documentation specifies short-circuit protection capability, control-side under-voltage protection, and fault-output functionality. The protection system can detect certain abnormal operating conditions and provide a fault signal to the external controller. The exact protection thresholds and timing should always be checked against the official datasheet when designing or repairing equipment.

The PS21564-SP 600V 15A IPM has a specified control supply voltage of up to 20V for the relevant control supply terminals. The module also provides high-side bootstrap supply terminals for the upper IGBT gate-drive circuits. The input control terminals accept the external switching signals used to control the individual inverter phases.

For motor-control applications, the module receives PWM control signals from a microcontroller, DSP, or dedicated motor-control IC. The integrated driver circuits then control the internal IGBTs according to the applied input signals. By changing the PWM duty cycle and switching sequence, the inverter can control the output voltage and frequency supplied to a three-phase motor.

The PS21564-SP68AT4 can therefore be suitable for applications where a compact three-phase inverter power stage is required. Potential applications include air-conditioner inverter boards, washing-machine motor drives, refrigerator compressors, fan motors, pumps, small industrial motor drives, and other compatible AC motor-control systems.

For air-conditioning applications, an IPM such as the PS21564-SP series can form part of the outdoor-unit inverter power stage used to drive a compressor motor. The inverter controller regulates the switching of the IGBT bridge to control compressor speed according to system requirements. The actual suitability of the module depends on the original equipment design and the electrical specifications of the replacement device.

The module is also suitable for compatible three-phase motor-drive systems. Its integrated six-switch IGBT bridge allows the three motor phases to be controlled from a common DC bus. The integrated free-wheeling diodes provide current paths during switching and motor current recirculation.

The 600V voltage rating makes this module suitable for high-voltage DC-link inverter applications within its specified operating limits. The official documentation specifies a maximum supply voltage of 450V and a supply-voltage surge rating of 500V under the stated conditions, while the IGBT collector-emitter voltage rating is 600V. These values should not be confused with one another: the 600V rating is the semiconductor blocking voltage rating, whereas the recommended DC bus operating voltage is subject to the module’s specified supply limits and application conditions.

The module has a 15A collector-current rating per IGBT at the specified case temperature. A peak current rating of 30A is specified for a pulse duration of less than 1ms under the datasheet’s stated conditions. Actual continuous operating current depends on switching frequency, case temperature, motor power factor, PWM method, thermal management, and other application parameters.

Thermal management is an important consideration when using the PS21564-SP68AT4 600V 15A IGBT IPM. The module documentation specifies a case operating temperature range of approximately -20°C to +100°C and a storage temperature range of -40°C to +125°C. The maximum junction temperature of the integrated power chips is higher under specified conditions, but the documentation recommends limiting the average junction temperature for safe module operation.

The module’s transfer-molded construction provides an insulated package suitable for compact inverter assemblies. The technical documentation specifies a 2500Vrms isolation voltage under the stated test conditions for the PS21564-SP module. This isolation helps separate the power semiconductor section from the mounting or heatsink structure when installed according to the manufacturer’s requirements.

The PS21564-SP family uses a Dual-In-Line Package (DIP) Intelligent Power Module format. Distributor information identifies the device as a 37-PowerDIP module with through-hole mounting. This package style allows the module to be mounted directly onto a compatible PCB and connected to an appropriate thermal management arrangement.

For electronics repair and replacement applications, the PS21564-SP68AT4 should be matched carefully against the original module. Even if another IPM has the same 600V and 15A ratings, it may not be a direct replacement. The internal circuit configuration, pin arrangement, control logic, protection functions, package dimensions, and thermal characteristics must all be compatible.

Before installing a replacement module, technicians should inspect the complete inverter system. A failed IPM can be caused by a shorted motor or compressor, damaged DC-link capacitors, faulty gate-drive components, excessive voltage spikes, poor cooling, or PCB damage. Replacing only the IPM without identifying the original failure cause can result in repeated component failure.

The PS21564-SP68AT4 is especially useful as a replacement component when the exact original part number is confirmed. Because the suffix 68AT4 could not be independently verified in the available public documentation, buyers should compare the physical marking and datasheet information before listing this suffix as a confirmed manufacturer order code. The publicly available documentation I found identifies the core device as PS21564-SP.

Overall, the PS21564-SP 600V 15A three-phase IGBT Intelligent Power Module is a compact integrated power solution for inverter and motor-control applications. It combines a three-phase IGBT inverter bridge, free-wheeling diodes, gate-drive circuitry, bootstrap functionality, and protection features into a single DIP-IPM package.

Its combination of 600V voltage capability, 15A current rating, integrated IGBT bridge, built-in protection, and compact package makes it suitable for compatible low-power motor drives and inverter systems. It is particularly relevant to applications such as household appliance motor control, air conditioners, washing machines, refrigerators, and other equipment requiring compact three-phase inverter power stages.
