Offering what it describes as unmatched power density and efficiency, Qorvo says its latest 1200V SiC half-bridge and full bridge power modules are set to revolutionise the industries of electric vehicle (EV) charging, solar inverters, and industrial power supplies.

The modules are available from distributor Ineltek.

At the heart of Qorvo's SiC Power Modules is silicon carbide (SiC) technology with its ability to conduct electricity more efficiently at high temperatures than traditional silicon-based solutions.

For engineers and technical professionals, this means a significant leap in efficiency - enabling smaller, more powerful devices that generate less heat and therefore operate more efficiently.

Qorvo's SiC power modules provide efficiency and power density through several key features: ​

  • Low Rds(on) and body diode voltage drop: The modules have a low Rds(on) (as low as 9.4 mohm) and a very low body diode voltage drop (1.63V). ​ This combination helps to minimise conduction losses, allowing more power to be delivered to the load and increasing overall efficiency.
  • Fast switching capability: These modules utilise a unique Cascode JFET configuration, which enables fast switching. ​ This reduces turn-off switching losses by 74% compared to competing solutions. ​ Faster switching allows for more efficient power conversion and reduces power losses.
  •    Increased power cycling capability: Qorvo's SiC power modules deliver 2x the power cycling capability compared to competing SiC modules. ​ This means that they can handle more power cycles without degradation, ensuring long-term reliability and efficiency.

The 1200V rating of Qorvo's SiC modules represents the high voltage threshold these modules can handle, making them ideal for high-power applications such as EV charging stations and solar inverters.

This voltage capacity, combined with the natural efficiency of SiC material, provides a robust solution capable of handling the rigorous demands of modern power systems.

For the EV charging market, Qorvo's SiC Power Modules enable faster, more efficient charging stations that can serve more vehicles without the need for extensive power grid upgrades.

In the realm of solar energy, these modules allow for more efficient conversion of solar power to usable electricity, improving the overall efficiency of solar inverters and contributing to a greener planet.

These SiC Power Modules are designed with superior electrical and thermal performance in mind. Their high efficiency translates to lower energy loss in the form of heat, which in turn means less stress on the components and extended product lifespan. This performance is critical in applications where reliability and durability are paramount, such as in industrial power supplies.


The design of Qorvo's SiC Power Modules reduces the thermal stress on the components, enabling an enhanced product lifetime, offering a more reliable and cost-effective solution over their lifespan.
