SiC diodes portfolio now addresses automotive and wider industrial applications

Nexperia has announced that its class-leading 650V, 10A SiC Schottky diode is now automotive qualified (PSC1065H-Q) and offered in real-two-pin (R2P) DPAK (TO-252-2) packaging, making it suited to various applications in EVs and other automobiles. Also, in a further extension to its portfolio of SiC diodes, the company is now offering industrial-grade devices with current ratings of 6 A, 16A, and 20A in TO-220-2, TO-247-2, and D2PAK-2 packaging to enable greater design flexibility. These diodes meet the challenges of demanding high voltage and high current applications, including switched-mode power supplies, AC/DC and DC-DC converters, battery-charging infrastructure, motor drives, UPS and photovoltaic inverters for sustainable energy production.

The merged PiN Schottky (MPS) structure of these devices supplies additional advantages over similar competing SiC diodes, including outstanding robustness against surge currents. This eradicates the necessity for extra protection circuitry, thereby greatly reducing system complexity and allowing hardware designers to achieve higher efficiency with smaller form factors in rugged high-power applications. The company's consistent quality across various semiconductor technologies provides designers with confidence in the reliability of these diodes.

Also, the company's 'thin SiC' technology delivers a thinner substrate (one-third of its original thickness), dramatically reducing the thermal resistance from the junction to the back-side metal. This results in lower operating temperature, higher reliability and device lifetime, higher surge current capability, and lower forward voltage drop.

"We've seen an excellent market response to the initial release of our SiC diodes. They have proven themselves in design-ins with one notable example in power supplies for industrial applications, where customers have achieved especially good results. The superior reverse recovery of these diodes translates to high efficiency in real-world use", says Katrin Feurle, senior director and head of Product Group SiC Diodes and FETs at Nexperia. "We are particularly excited that this is our first automotive-qualified product, and it is already recognised by major automotive players for its performance and reliability."
