Semiconductor Qualification – Understanding the Transition from AEC-Q100 Rev-H to Rev-J

These updates reflect the evolving needs of the automotive industry, ensuring that semiconductor components can meet higher reliability and performance standards under varying conditions.

Key changes include:

  • Greater Emphasis on Automotive
  • New ESD tolerance requirements for 28-nanometer and RF chips.
  • Revised Temperature Cycling Test (TCT) conditions.
  • Introduction of Bias Temperature Instability (BTI) testing.

These updates aim to enhance the reliability and performance of automotive semiconductor devices, aligning with the industry’s focus on safety and technological maturity. For a deeper dive into each change the table below provides more explanation and the documents are free to download from the AEC website at:


The transition from AEC-Q100 Rev H to Rev J represents a significant update, incorporating new sections, enhanced guidelines, and a clear focus on automotive applications. Rev J is more detailed, reflecting current industry practices and requirements, making it a comprehensive guide for stress test qualification in automotive integrated circuits.
