SiC diodes suit demanding automotive applications

ON Semiconductor has announced an expansion of its silicon carbide (SiC) Schottky diode portfolio to include devices specifically intended for demanding automotive applications. The company says the new automotive grade SiC diodes deliver the reliability and ruggedness needed by modern automotive applications, along with the numerous performance benefits synonymous with wide band gap (WBG) technologies.

SiC technology can provide superior switching performance and higher reliability compared with silicon devices. The diodes have no reverse recovery current, and switching performance is independent of temperature.

These SiC diodes are available in popular surface mount and through-hole packages, including TO-247, D2PAK and DPAK. The FFSHx0120 1200 Volt (V) Gen1 devices, and FFSHx065 650 V Gen2 devices offer zero reverse recovery, low forward voltage, temperature independent current stability, low leakage current, high surge capacity and a positive temperature coefficient. They aim to deliver improved efficiency while the faster recovery increases switching speeds, thereby reducing the size of magnetic components required.

To meet the robustness requirements and perform reliably in the harsh electrical environments of automotive applications, the diodes have been designed to withstand high surge currents. They also include a patented termination structure that improves reliability and enhances stability. Operating temperature range is -55 degrees C to +175 degrees C.

The new devices will be demonstrated during PCIM along with the company’s solutions in areas such as wide band gap, automotive, motor control, USB Type-C power delivery, LED lighting and smart passive sensors for industrial predictive maintenance applications.

ON Semiconductor will also be demonstrating its advanced SPICE model that is sensitive to process parameter and layout perturbations and therefore represents a step-change versus current industry modelling capabilities.

Using this tool, circuit designers can evaluate technologies early in the simulation process. A further benefit of ON Semiconductor’s SPICE agnostic model is that it can port across multiple industry standard simulation platforms.
