JEDEC Unveils SiC Standards to Boost Power Electronics Reliability
Event summary
- JEDEC released JEP203 and JEP204 guidelines for SiC power semiconductors on June 3, 2026.
- JEP203 focuses on short-circuit evaluation for power MOSFETs in EVs, industrial drives, and energy infrastructure.
- JEP204 provides a framework for stress-testing SiC devices to ensure long-term reliability.
- The JC-70 committee, with over 70 member companies, developed the standards to accelerate SiC adoption.
The big picture
The release of JEP203 and JEP204 marks a critical step in standardizing SiC technology, addressing reliability concerns that have been a barrier to wider adoption. As the power electronics industry shifts toward wide bandgap (WBG) semiconductors, these guidelines provide a unified framework that could enhance confidence among engineers and manufacturers. The involvement of over 70 member companies in the JC-70 committee underscores the industry's commitment to advancing SiC adoption.
