Silicon Carbide (SiC) MOSFET Intelligent Power Module

The CMT-PLA3SB12340AA is a Silicon Carbide (SiC) Power Module from Cissoid, engineered for highly efficient power conversion in demanding applications.

It is a 3-phase, 1200V/340A SiC MOSFET intelligent power module that integrates power switches and a gate driver based on the CISSOID HADES2 chipset. The module is cooled using a lightweight AlSiC flat baseplate, making it ideal for high-power-density converters. It is designed to operate at junction temperatures of up to 175°C, ensuring reliable performance in harsh environments.

This solution provides significant advantages over traditional IGBT modules by fully utilising SiC technology, offering:

High Efficiency: The low switching losses of SiC reduce heat generation, enhancing overall power efficiency.
High Power Density: The compact design allows for a smaller footprint, optimising system architecture.
High Reliability: Operation at elevated temperatures improves durability, particularly for industrial and automotive applications.

The integration of the gate driver with the power module delivers a fully validated and optimised solution. It ensures faster switching speeds, minimises losses, and provides robustness against dI/dt and dV/dt. Additionally, the module includes built-in protection features such as:

• Desaturation protection (Desat)
• Soft Shutdown (SSD)
• Negative gate drive (-3V)
• Active Miller Clamping (AMC)
• Gate-Source Short-circuit Protection
• Open-drain fault reporting (per side or per phase)
• Turn-On/Off delay: 180ns (typical)
• Under-voltage lockout (UVLO) on VCC and internally generated secondary supplies

These features make the CMT-PLA3SB12340AA ideal for high-power applications requiring robust, efficient, and reliable power management solutions.

Typical Applications for the CMT-PLA3SB12340AA include:

Automotive Industry: Electric and hybrid vehicle powertrains, High-power battery chargers
Renewable Energy: Solar inverters, Wind turbine power systems, Energy storage systems
Industrial Sector: Industrial motor drives, High-efficiency switch mode power supplies (SMPS), Uninterruptible power supplies (UPS)
