Infineon HiRel FIT Rate Tool
In high-reliability industries such as aerospace and defense, the reliability of electronic components is paramount. At Infineon, we understand the importance of delivering industry-leading solutions that can operate flawlessly even in the most extreme environments.
One key metric used to measure the reliability of electronic components is the Failure In Time (FIT) rate. The FIT rate represents the number of failures that can be expected in one billion hours of operation. This metric provides a critical insight into the performance of components in high-reliability applications.
To support our customers in selecting the most reliable solutions for their high-reliability applications, we have developed a FIT rate tool specifically designed for our HiRel power discretes. This intuitive tool enables you to estimate the FIT rate of our components and make informed decisions about the solutions that best meet your requirements.
With Infineon's FIT rate tool, you can:
- Estimate the FIT rate of our HiRel power discretes
- Compare the reliability of different components
- Select solutions that meet the stringent requirements of high-reliability applications
At Infineon, we are committed to delivering innovative solutions that meet the highest standards of reliability and performance. Our FIT rate tool is just one example of our dedication to supporting our customers in their pursuit of excellence. Explore our industry-leading portfolio of high-reliability solutions and discover how we can help you achieve your goals.
To utilize the FIT rate tool, follow these steps:
- Device Selection: Begin by selecting a device from the search bar. This will enable you to access the relevant reliability data for the chosen device.
- Input Parameters: If reliability data is available for the selected device, you will be prompted to enter the following parameters:
- Thermal activation energy
- Case temperature
- Chi square confidence level
Please note that not all Infineon HiRel power discretes may have available reliability data. If you are unable to find the desired Infineon HiRel device in the tool, please contact our support team at hirel-discretes@infineon.com for further assistance.
The FIT rate estimations provided by this tool are based on the industry-recognized standard JEDEC JESD85, "Methods for Calculating Failure Rates in Units of FITs". To ensure the highest level of accuracy, our calculation methodology employs a sample size that comprises similar products from the same technology generation and polarity. This approach enables us to leverage the statistical advantages of a larger sample size, thereby increasing the reliability of our FIT rate estimates.
For HiRel MOSFETs, our FIT test data incorporates High Temperature Reverse Bias (HTRB) data at a minimum stress level of 80%. The resulting FIT rate represents an empirical estimate of die wear-out, which is independent of package and Total Ionizing Dose (TID) rating. It is essential to note that the actual FIT rate of a given component may vary depending on its specific application and operating conditions, which may deviate from the estimation provided by this tool. All reliability tests are conducted in accordance with relevant industry standards, ensuring the highest level of quality and consistency.

Limitations of FIT Rate Calculations
It is essential to understand that the FIT rate calculations provided by this tool are not intended for use in functional safety applications. The tool is designed to provide a general estimate of reliability, and its output should not be relied upon for safety-critical purposes.
For applications requiring compliance with functional safety standards, it is necessary to follow the guidelines and methodologies outlined in relevant industry standards, such as IEC 62380, IEC 61709, SN 29500, FIDES, and others. These standards provide the necessary framework for estimating the raw FIT rate, which is a critical component of safety-critical system design.
By using this tool, you acknowledge that you understand and accept these limitations, and that you will not use the calculated FIT rate for functional safety purposes without further evaluation and validation in accordance with applicable industry standards.
