Mitsubishi PS11036 | A Robust 600V/30A DIP-IPM for Compact Motor Drives
The Mitsubishi PS11036 is a highly integrated Intelligent Power Module (IPM) designed to streamline the development of low-to-medium power three-phase inverter applications. By co-packaging six 600V/30A IGBTs with optimized gate drivers and comprehensive protection circuits into a single compact DIP package, this module offers a proven, reliable solution that accelerates time-to-market and reduces system complexity for engineers.
Core Engineering Advantages
- Simplified System Design: Integrates the power stage (IGBTs) and control stage (gate drive, protection) into one component, significantly reducing PCB space, component count, and design complexity.
- Built-in Reliability: Features on-board protection for critical fault conditions, including short-circuit (SC), over-temperature (OT), and control supply under-voltage (UV), safeguarding the power electronics from catastrophic failure.
- Optimized Switching Performance: The integrated gate drive is precisely matched to the IGBT characteristics, ensuring efficient switching while minimizing EMI generation, a common challenge in compact motor control systems.
- Reduced Assembly Cost: The single-package DIP form factor simplifies manufacturing and mounting processes compared to designing with dozens of discrete components.
Ideal Application Scenarios and Value Proposition
The Mitsubishi PS11036 excels in applications where space, reliability, and development speed are critical design drivers. Its architecture provides tangible benefits across several key areas:
- Appliance Motor Control (Air Conditioners, Washing Machines): In consumer appliances, cost and reliability are paramount. The PS11036's high level of integration reduces the bill of materials (BOM) and its robust, built-in protections ensure a long operational lifespan, even under fluctuating load conditions.
- Small Industrial Pumps and Fans: For small Variable Frequency Drives (VFDs), the module's compact footprint allows for smaller overall drive dimensions. The integrated bootstrap diodes further simplify the high-side gate drive power supply, a crucial element for cost-effective three-phase control.
- General-Purpose Low Power Inverters: The module serves as a powerful building block for any inverter design up to approximately 2.2kW. Engineers can focus on higher-level control logic, knowing the power stage is pre-validated and protected, drastically cutting down on the typical challenges of robust gate drive design.

Is the PS11036 Right for Your Design?
Choosing between an integrated solution like the Mitsubishi PS11036 and a discrete design involves clear trade-offs. This IPM is the ideal choice when design goals prioritize speed, reliability, and a compact footprint. While a discrete solution using individual IGBTs and gate drivers might offer more granular control over switching parameters, it introduces significant design overhead in terms of layout, component matching, and implementing reliable protection circuits.
The PS11036 removes these variables, offering a pre-engineered solution that has been a workhorse in the industry for years. For teams looking to develop robust, cost-effective motor drives without dedicating extensive resources to power stage design and validation, this DIPIPM™ from Mitsubishi is an exceptionally strong candidate.
Frequently Asked Questions (FAQ)
Q1: What are the key considerations for the bootstrap circuit when using the PS11036?
A: The PS11036 has integrated bootstrap diodes, which is a major advantage. The primary consideration is selecting the correct bootstrap capacitor value. This depends on the PWM frequency, the IGBT's gate charge (QG), and the acceptable voltage drop on the high-side supply. A value that is too small will cause under-voltage trips, while one that is too large may not fully charge at high duty cycles.
Q2: How do I manage thermals for a DIP-IPM like this?
A: Effective thermal management is crucial for reliability. The PS11036 must be mounted on a heatsink with a suitable thermal interface material (TIM). The clamping torque must be within the datasheet's specified range to ensure optimal thermal contact without inducing mechanical stress on the module. Calculating the total power loss (conduction + switching) is the first step to sizing the required heatsink correctly for your application's ambient temperature.
