en.Wedoany.com Reported - The JEDEC Solid State Technology Association has released two new guidelines for silicon carbide (SiC) power semiconductors, designated JEP203 and JEP204, aimed at standardizing the evaluation, qualification, and reliability testing processes for these devices. These documents were drafted by the association's JC-70.2 Silicon Carbide Subcommittee and are now available for free download on the JEDEC website.
As SiC devices continue to gain penetration in power electronics applications such as electric vehicles, industrial motor drives, renewable energy systems, and power infrastructure, the reliability challenges they face are becoming increasingly prominent. The new guidelines are designed to address these pain points.
Among them, JEP203, titled "Guideline for Short Circuit Evaluation in Power Conversion Transistors," specifically provides recommendations for short-circuit capability testing of power MOSFETs. This document aims to help engineers unify test methods, optimize protection circuit design, and enhance system robustness under fault conditions. As SiC devices evolve toward higher power density and faster switching speeds, accurately understanding their short-circuit characteristics has become a core prerequisite for ensuring safe and reliable operation.
The other publication, JEP204, titled "Catalog of Stress Procedures for Silicon Carbide Devices for Power Electronic Conversion," serves as a comprehensive reference covering reliability, environmental endurance, and robustness testing. It provides a general framework for evaluating long-term device performance and reliability, enabling manufacturers, qualification engineers, and system designers to adopt more consistent evaluation methods.
These two guidelines aim to promote a higher degree of consistency in testing and qualification methods across the industry, thereby enhancing confidence in deploying next-generation SiC power systems. Standardized evaluation procedures enable more comparable and repeatable performance assessments within the industry, accelerating the adoption and application of the technology.
The aforementioned documents were developed under the leadership of the JC-70 committee, which focuses on wide bandgap semiconductor standardization. Established in 2017 with 23 initial member companies, the committee has now expanded to over 70 participating organizations worldwide, including semiconductor manufacturers, system developers, test equipment suppliers, research institutions, and academic groups specializing in gallium nitride (GaN) and silicon carbide technologies.
The continued expansion of the committee reflects the industry's urgent need for common standards on reliability, test methods, and electrical characteristics for wide bandgap power semiconductors. The JC-70 committee plans to hold its next meeting on July 15, 2026, continuing to provide standardization support for the widespread adoption of advanced power semiconductor technologies.
