PT150S8 | 800V 150A CIB Power Integrated Module (PIM) for Compact Drives
The PT150S8 is not merely an IGBT module; it is a highly integrated power stage engineered to streamline the design of compact and efficient power conversion systems. By co-packaging a three-phase converter, a three-phase inverter, and a brake chopper into a single, thermally efficient module, the PT150S8 provides a robust foundation for modern AC motor drives, servo systems, and uninterruptible power supplies. Its design philosophy centers on maximizing power density while minimizing system complexity and assembly costs.
- All-in-One CIB Topology: Integrates a full three-phase input rectifier, a three-phase output inverter, and a brake chopper circuit, significantly reducing PCB footprint and component count.
- Advanced Trench Field Stop Technology: Delivers an optimized balance between low conduction losses (VCE(sat)) and minimal switching losses, enhancing overall inverter efficiency.
- High Thermal Performance: Rated for a maximum operating junction temperature (Tjmax) of 175°C, providing a wide thermal margin for reliable operation in demanding industrial environments.
- Simplified System Design: The integrated nature of the PT150S8 reduces parasitic inductance, simplifies gate drive layout, and accelerates the time-to-market for new drive designs.

Engineered for Performance in Demanding Applications
The intrinsic design of the PT150S8 translates directly into superior performance and reliability in specific industrial applications. Its value extends beyond its specifications to how it solves real-world engineering challenges.
- Compact AC Motor Drives: For designers of Variable Frequency Drives (VFDs), the CIB topology is a game-changer. The PT150S8 enables the creation of extremely power-dense drives up to 75kW. The integrated brake chopper simplifies the management of regenerative energy during motor deceleration, an essential feature for applications like conveyors and cranes, thereby eliminating the need for a bulky and costly external braking unit.
- High-Performance Servo Drives: In precision motion control, system responsiveness is paramount. The low internal inductance and advanced Trench Field Stop IGBTs within the PT150S8 allow for the fast, clean switching required to control servo motors with high accuracy. This integration is critical for maintaining control loop stability in demanding robotic and CNC applications.
- Industrial Power Systems: For applications like uninterruptible power supplies (UPS) and welding power sources, the module's robustness and high integration simplify the power stage design, improve reliability by reducing solder joints and mechanical connections, and contribute to a more manufacturable end product.
Expert Q&A for the PT150S8
Our engineers frequently address key design questions. Here are two common inquiries regarding the PT150S8.
1. How does the 800V VCES rating provide an advantage over standard 650V modules?
The 800V rating provides a significantly larger safety margin for applications running on 400-480V AC lines. During switching events, especially under high dI/dt conditions, voltage overshoots caused by stray inductance can easily exceed the limits of a 650V device. The higher blocking voltage of the PT150S8 enhances the system's robustness against line voltage fluctuations and transient spikes, reducing the need for oversized snubber circuits and improving long-term reliability.
2. With three power stages in one package, what are the key thermal management considerations?
The integrated CIB design concentrates heat generation, making effective thermal management a critical design aspect. The module’s flat baseplate and low junction-to-case thermal resistance (Rth(j-c)) are engineered for efficient heat transfer. However, success hinges on the external thermal stack. A high-performance Thermal Interface Material (TIM) and a properly simulated and sized heatsink are non-negotiable. It is crucial to model the combined losses from the rectifier, inverter, and brake chopper under worst-case load profiles to ensure the junction temperature remains well below the 175°C maximum.
