In the last edition of Space Brief, I discussed how Total Ionizing Dose (TID) performance could vary wafer-to-wafer for bipolar transistors. If radiation qualified bipolar transistors are not available for a satellite build, then delays can be significant, totaling 7 months or more if the die has to be fabricated, packaged, and radiation tested. To avoid this issue, Microsemi is continuing to build and pre-qualify die banks of our popular bipolar transistors to ensure our customers are not waiting for 100krad (10mrad/sec) radiation lot acceptance test data on these products.
Pre-qualified wafers of the JANSR2N2222A and the JANSR2N2907A are now ready for order. In addition, the JANSR2N3700 and JANSR2N2369A wafers will be available at the end of 2018.
To guarantee you receive low dose rate qualified die (ie…10mrad/sec or less) please specify, “10mRAD/sec low dose rate tested die” on the purchase order. In parallel, we are working with the Defense Logistics Agency (DLA) to create a specific part number so you can order the low dose rate products directly.
Through investments like this, Microsemi continues to show our commitment to the space power market by investing ahead of market needs!
