About HiRel FIT Rate Tool

Infineon offers an industry-leading solutions portfolio for high-reliability applications. FIT rate, or Failure In Time rate, is a commonly used measure of electronic components reliability. It is the number of failures that can be expected in one billion hours of operation. This metric is especially relevant for high-reliability electronics, such as those used in aerospace and defense applications.

This FIT rate tool is designed to help customers estimate this measure for Infineon’s HiRel power discrete's and choose solutions that can operate reliably even in the most extreme environments.

How it works

In the tool, start by selecting a device in the search bar. If reliability data is available, you may enter values for thermal activation energy, case temperature and Chi square confidence level.

Note that data may not available for all Infineon HiRel power discrete's. If you’re unable to find an Infineon HiRel device in the tool, please contact  hirel-discretes@infineon.com.

Calculation Details

FIT rate estimations are per JEDEC JESD85, Methods for Calculating Failure Rates in Units of FITs. The sample size used to calculate FIT rate in this tool includes similar products from the same technology generation and polarity to gain higher statistical accuracy. Within a product family, all members are equal with respect to the fabrication process and technology design.

For HiRel MOSFETs, FIT test data includes HTRB data at minimum 80% stress levels. The FIT rate, an empirical estimate of die wear-out, is independent of package and TID rating. The actual FIT rate of a given component depends on its application and may deviate from the estimation shown in this tool. All reliability tests are performed according to the relevant industry standards.

Disclaimer

A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
