Modular SiC Inverter Platform by Cissoid at Rhopoint

As industries push the boundaries of electrification, the demand for high-efficiency inverter modules that offer both power density and thermal robustness is more critical than ever. From electric vehicles (EVs) to renewable energy systems and aerospace-grade power supplies, engineers are seeking scalable solutions that combine compact form factors with reliable performance under extreme conditions.

The Cissoid CMT-PLA3SB12340A, distributed by Rhopoint Components, meets this challenge head-on. Leveraging the benefits of Silicon Carbide (SiC) technology, this intelligent power module enables higher switching speeds and lower conduction losses compared to traditional silicon or IGBT-based solutions.

Its design addresses key pain points in today’s power conversion landscape, where efficiency, space savings, and thermal performance must converge. Whether it's for EV drivetrain systems, solar inverters, or high-altitude avionics, this scalable SiC solution delivers the performance modern applications demand while future-proofing product development against evolving standards and expectations in power electronics.

Power Density Meets Thermal Robustness in a Compact Form Factor

The CMT-PLA3SB12340A stands out as a cutting-edge 1200V SiC MOSFET solution designed to meet the stringent demands of modern power electronics. Engineered to handle a maximum continuous current of 340A at 25°C, this intelligent power module is ideal for high-load environments where thermal performance and compact design are non-negotiable.

At the heart of the module lies a high-efficiency SiC switching structure that enables rapid switching frequencies of up to 50kHz (with temperature-based derating), ensuring fast response times in demanding applications. Its low R_DS(on) SiC characteristic—just 3.25mΩ typical—reduces conduction losses, maximising overall system efficiency and enabling more compact thermal management solutions.

Designed with a rugged AlSiC flat baseplate, the module offers exceptional thermal conductivity while maintaining structural integrity in environments where junction temperatures may reach up to 175°C. The compact footprint (34 x 104 x 154mm) and robust electrical isolation (up to 5000VDC) make it highly suitable for automotive inverters, industrial motor drives, and renewable energy converters where performance and form factor must align.

Integrated Gate Driver for Seamless, Safe Operation

The CMT-PLA3SB12340A is equipped with an integrated SiC gate driver built on the high-reliability CISSOID HADES2 chipset, streamlining design and boosting system-level efficiency. This embedded control architecture reduces the need for external components, offering a fully validated and compact solution ideal for high-performance inverter systems.

Engineered for fast, noise-immune switching, the driver delivers a typical turn-on/turn-off delay of just 180ns, enabling superior dynamic performance at high frequencies. But beyond speed, it also prioritises protection and reliability. Critical safety features include:

• Desaturation protection (Desat) for short-circuit monitoring
• Active Miller clamping (AMC) to prevent false turn-on during high dV/dt events
• Soft shutdown (SSD) for controlled fault responses
• Gate-source short-circuit protection and open-drain fault reporting
• Under-voltage lockout (UVLO) on both V_CC and internal secondary supplies

Together, these features make the module exceptionally robust for applications in electric transport, renewable systems, and industrial automation, where safety and continuous operation are paramount. The high integration level also simplifies PCB layout, shortens design cycles, and improves reliability by reducing potential points of failure.

Modular Power Architecture for Next-Gen Electrification

The CMT-PLA3SB12340A is more than just a power module—it’s a building block in a wider modular inverter design strategy that accelerates system integration and scalability. Its flexible architecture allows engineers to adapt power levels and configurations without overhauling the entire design, making it ideal for rapidly evolving applications in electrification and energy conversion.

This application-agnostic power module supports both bench-top evaluation and embedded system deployment, enabling streamlined proof-of-concept and production-level design. With footprint-compatible variants and comprehensive reference materials, it empowers developers to iterate quickly while maintaining performance integrity.

Supported application domains include:

• Automotive and e-Mobility: EV and hybrid powertrains, onboard chargers
• Renewables and Storage: Solar inverters, battery energy storage systems
• Industrial Automation: Motor drives, UPS, SMPS
• Aerospace and Defence: High-temp avionics, rugged military power supplies
• Marine and Rail: Propulsion and traction systems for transport electrification
