Total dose test of commercial off-the-shelf components to be used in power supply for space experiments

Commercial off-the-shelf components have been tested for their use on the power supplies of the AMS and PAMELA experiments. The test has been performed using the CALLIOPE Co60 source at the Casaccia (Rome-Italy) Laboratory of ENEA according to the ESA/SCC 22900 specifications. The total dose for this test: was 30 krads. Measurements of relevant parameters for each component has been taken at 3, 10 and 30 krads. Annealing and ageing has also been performed according to the ESA specification. The results on the degradation of performances in discrete transistors, op amps, regulators and other analog and digital components are reported.
