SiC Supply Is Becoming More Differentiated

Silicon carbide (SiC) illustrates this changing market particularly well. Supply for established automotive SiC devices has eased in some areas as EV demand has softened and additional wafer capacity has come online.

At the same time, demand for higher-voltage SiC devices is increasing in applications such as AI infrastructure, high-power power supplies and energy systems. This is creating new pressure on available manufacturing capacity.

As a result, there is no longer one simple answer to the question of “SiC availability.” Supply depends on factors such as voltage class, device technology, qualification requirements, application and manufacturing capacity.

For engineers, this makes a component-level approach increasingly important. Rather than asking whether the semiconductor shortage is over, the more useful questions are: Which components on the BOM remain constrained? Which are readily available? And what is driving the difference?

These considerations can influence not only purchasing decisions, but also component selection, second sourcing and long-term production planning.

Reliable Supply of Discrete Semiconductors

As a producer of discrete semiconductors, Diotec focuses on technologies that are essential to power management, switching and circuit protection.

Our portfolio includes not only SiC MOSFETs and MOSFETs, but also TVS and ESD diodes, BJTs and digital transistors, supporting a wide range of industrial, automotive and power electronics applications.

In a market where semiconductor availability increasingly depends on the individual device rather than the broader component category, reliable production and predictable lead times are becoming important factors alongside electrical performance and cost.

For technical buyers and design engineers, understanding these differences is key to managing supply-chain risk - and ensuring that today's component choices remain viable throughout the production lifecycle.
