Nexperia and KYOCERA AVX to produce silicon-carbide rectifier module

Nexperia, a semiconductor provider, announced it has entered into a partnership with KYOCERA AVX Components, an international supplier of advanced electronic components, to jointly produce a new 650 V, 20 A silicon-carbide (SiC) rectifier module.

The new rectifier module will be for high-frequency power applications ranging from 3 to 11 kW power stack designs — aimed at applications like industrial power supplies, EV charging stations, and on-board chargers.

This release will represent a further deepening of the existing, long-lasting partnership between the two companies.

Space-saving and weight reduction are the key requirements for manufacturers of the next-generation power applications. This new SiC rectifier module’s compact footprint will help maximize power density, reducing the amount of required board space and lowering the overall system cost.

Thermal performance will be optimized using a combination of top-side cooling (TSC) and an integrated negative temperature coefficient (NTC) sensor, which monitors the device temperature and provides real time feedback for device or system-level prognosis and diagnosis. This rectifier module has a low inductance package to enable high frequency operation and it has been qualified to operate with a junction temperature of up to 175° C.

“This collaboration between Nexperia and KYOCERA AVX combines cutting edge silicon carbide semiconductors with state-of-the-art module packaging and will allow Nexperia to better serve the market demand for power electronic products which offer exceptionally high levels of power density,” according to Katrin Feurle, senior director of the Product Group SiC at Nexperia. “The release of this rectifier module will represent the first step in what is envisaged as a long-term SiC partnership between Nexperia and KYOCERA AVX”.

Nexperia expects samples of the new SiC rectifier modules to be available in the first quarter of 2024.
