Nexperia partners with KYOCERA AVX to produce a 650 V silicon carbide rectifier module

1 min read

Nexperia has entered into a partnership with KYOCERA AVX Components to jointly produce a 650 V, 20 A silicon carbide (SiC) rectifier module.

Intended for high frequency power applications ranging from 3 kW to 11 kW power stack designs, the module is 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.

Both space-saving and weight reduction are the key requirements for manufacturers in terms of the next generation of power applications and the compact footprint of this new SiC rectifier module will help to maximise power density, thereby reducing the amount of required board space and lowering the overall system cost.

Thermal performance is optimised 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,” explained 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”.

Thomas Rinschede, Deputy Vice President Sensing and Control Division at KYOCERA AVX Components Sensing and Control Division, welcomed the extension of what has been a successful partnership with Nexperia into the production of silicon carbide modules for power electronics applications.

“Nexperia’s manufacturing expertise combined with KYOCERA module know-how make a compelling offering for customers looking to achieve higher power densities using wide bandgap semiconductor technology,” Rinschede said.

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