Total Ionizing Dose (TID) testing, Update on ESCC22900 and discussion on TID response variability (part to part and lot to lot) and impact on sampling size and test requirements.
A new issue (issue 5) of ESCC22900 TID test standard will be released this year. The changes will be presented. Then, study results about part to part and lot to lot TID sensitivity variability on bipolar linear devices will be presented. Impact on sample size and testing requirements will be discussed.
TID Variability Within a Lot and Lot to Lot
ESA / TRAD study
- Test of 3 types of linear bipolar devices
- AD584, AD
- LM124, T
- TL1431, STM
- 3 lots per device type
- 30 parts per device type per lot
NASA GSFC study (R. Ladbury, IEEE Trans NucSci, Vol. 56, 2009)
- Analysis of historical data on 5 types of linear bipolar devices
- > 7 lots per device type
