Diodes and Rectifiers - Schottky

Silicon carbide (SiC) SBDs are compact semiconductor devices renowned for their utility as one-way switches in power conversion systems. Their efficiency is attributed to the unique properties of silicon carbide: excellent thermal conductivity, an extremely low thermal expansion coefficient, and remarkable resistance to thermal shock. Generally, SiC SBDs outperform standard diodes, as they can function at higher current densities with minimal forward voltage drop, resulting in significantly less energy loss.

However, the manufacturing process for silicon carbide diodes has historically been complex and costly. Fortunately, through a research collaboration with QMF, innovative patented methods have emerged, greatly expediting production while reducing costs. By integrating standard procedures from SiC wafer manufacturing, we have revolutionized the design of Schottky components. As a result, we can efficiently accommodate customer-specific requirements in terms of forward voltage and current ratings. This streamlined production leads to lower prices for end-users, who will benefit from these products, particularly in solar inverter, motor drive, electric vehicle charger, and uninterruptible power supply applications.

Currently, Quest can supply SiC SBDs operating within a voltage range of 600 V. Ongoing research suggests that even higher voltage capacities may soon be attainable. Presently, we offer products in the TO247 package or as Bare Die silicon carbide Schottky diodes, adequately covering the voltage range from 650 V.
