White Paper: Measuring SiC Schottky Diode Ruggedness with A High Voltage Pulse Generator
When the first generation of silicon carbide Schottky diodes was introduced more than 10 years ago, their widespread adoption was somewhat challenged by unforeseen dV/dt limitations within certain manufacturers’ devices. In particular, devices with lower dV/dt capability were susceptible to failure from large in-rush currents. An initial reliability study of some of these early 600V SiC Schottky diodes reported an upper dV/dt limit of 55–60V/ns (volts per nanosecond), which unfairly tarnished the reputation of SiC diodes in general. Observing that their SiC Schottky diodes were not included in the initial study, researchers at Cree (now Wolfspeed, A Cree Company) performed a subsequent reliability study on their first-generation 600V SiC Schottky diode, and demonstrated that their SiC diodes could withstand a turn-on rate of 75V/ns and a turn-off rate of 100V/ns for more than 100,000 cycles without failure.

In the News: Enabling the Future of Electrically Powered Systems
The primary contributors to poor efficiency in power systems are the silicon semiconductor devices. Power semiconductor devices have been used in power converters since the 1960s, but silicon based power transistors and diodes that carry, switch, and convert the system power can be inefficient and slow to switch due to their intrinsic material properties. For power system users, SiC’s benefits over Si translate into lower system and operating costs, smaller physical footprints, lower cooling costs, and longer lasting, more reliable systems… Read more.
