3. Mitsubishi PM100CG1B120 IPM Core Integrated Functions and Self-Protection Mechanisms
This module features multiple self-protection functions to handle various abnormal states in power system operation, ensuring the safety of the module and the entire device:
- Over Temperature Protection: Real-time monitoring of the module’s internal temperature; when the temperature exceeds the safety threshold, an automatic protection mechanism is triggered to cut off power output, preventing chip damage or performance degradation due to high temperatures;
- Short Circuit Protection Protection: When a short circuit fault is detected in the power circuit, it quickly responds and blocks the current path to prevent excessive short-circuit current from burning out components, reducing equipment maintenance costs.
Undervoltage Lockout (UVLO): When the drive power supply voltage is lower than the rated operating range, it activates lockout protection to prevent undervoltage from causing module drive abnormalities or unstable output.
Error Mode Recognition and Signal Output: For various abnormal states such as over-temperature, short circuit, and undervoltage, it accurately identifies the fault type and outputs corresponding error signals, facilitating users to quickly locate problems through the control system and improving troubleshooting efficiency.

5. Mitsubishi PM100CG1B120 IPM Safety Operation Guidelines
When using the PM100CG1B120 Intelligent Power Module (IPM), to ensure reliable equipment operation and personnel safety, strict adherence to electrical safety, mechanical installation, and operational procedures is required. Given that the module operates with 1200V high voltage and high current, all operations must comply with industry safety guidelines and Mitsubishi Electric’s official recommendations.
Electrical Safety Precautions
Personnel Qualifications and Protection Standards: The PM100CG1B120 has a rated operating voltage of 1200V and is a high-voltage device. All installation, commissioning, and maintenance work must be performed only by qualified professionals with high-voltage operation qualifications. During operation, insulated gloves, insulated shoes, and other compliant personal protective equipment (PPE) must be worn, and electrical safety standards such as NFPA 70E must be strictly followed.
Isolated Power Supply: Separate isolated control power supplies should be used for the high-side and low-side gate drive circuits. Specific requirements are detailed in the datasheet to prevent grounding loops and noise issues.
- Power Supply Circuit Layout Requirements: When designing the power supply circuit layout, stray inductance and leakage inductance must be minimized. During rapid module switching (high di/dt), excessive inductance can easily cause transient overvoltages, potentially damaging components.
- Control Signal Timing Specifications: Before applying the control power supply voltage (VD), ensure all control inputs are connected to the corresponding power supply voltage via pull-up resistors to reliably “off” the module. After completing this step, apply the on/off control levels specified in the manual.
- Protection Circuit: The PM100CG1B120 has built-in over-temperature, short-circuit, and undervoltage protection functions. External circuitry must be specifically designed with signal processing loops to ensure accurate reception and response to the module’s “Fault Output (FO)” signal, achieving a smooth system shutdown under abnormal conditions.
6. Mitsubishi PM100CG1B120 IPM Mechanical and Thermal Safety Precautions
Heatsink Installation Requirements: Ensure the module is installed on a heatsink with the specified flatness (typically -50 µm to +50 µm within a 100 mm range) for optimal thermal contact and efficient heat dissipation.
Thermal Grease Application Standard: Apply appropriate thermal grease to the base plate (recommended thermal conductivity of at least λ = 0.9 W/(m·K)) to ensure optimal heat transfer.
Correct Torque: Tighten the mounting screws and terminal screws to the recommended torque specifications provided in the manufacturer’s application instructions. Tighten the screws on the module in stages to avoid applying uneven stress.
Maintain Temperature Limits: During operation, continuously monitor and ensure that the module junction temperature and case temperature remain below their rated maximum values. Even during long-term continuous operation, pay close attention to cumulative temperature rise to prevent performance degradation or shortened lifespan due to high temperatures.
7. Mitsubishi PM100CG1B120 IPM Operation Precautions
Electrostatic Discharge (ESD) Protection: The PM100CG1B120’s internal control IC is highly sensitive to static electricity. Strict anti-static measures must be taken when operating the module: wear anti-static gloves or wrist straps, ensure reliable grounding of the operator’s body and workbench, and lay conductive mats in the work area to prevent electrostatic damage to internal components.
Physical and Thermal Stress Protection: Do not apply excessive mechanical force or impact to the module. Bending the terminals is strictly prohibited. During soldering, precise control of temperature and operating time is required to avoid excessive thermal stress on the module, preventing package cracking or damage to internal circuitry.
Testing Specifications: Do not use non-dedicated equipment such as curve tracers to test this IPM, as such equipment may damage internal components. Testing must strictly follow the test procedures and standards specified in the PM100CG1B120 official datasheet or application instructions.
Important Note: Following the detailed guidelines in Mitsubishi Electric’s official application instructions is a core prerequisite for ensuring the safe and reliable operation of the PM100CG1B120. In summary, the Mitsubishi Electric PM100CG1B120 Intelligent Power Module (IPM) is based on a high-power specification of 1200V/100A.
