                         The space environment is harsh and radiation is the main problem 
                         for space systems which causes short and long term effects on 
                         electronic systems and components. In this case the key is to use 
                         resistant components and tolerant to radiation. The COTS 
                         components (Commercial Off-The Shelf) for some decades has been 
                         supplying some characteristic functions that space components do 
                         not have. However, because components (COTS) are not designed for 
                         the space environment, they are not guaranteed to function 
                         primarily due to radiation. Thus this research dissertation 
                         developed an understanding of the radiation and its effects on 
                         electronic components, especially transistors and in other 
                         semiconductor components, and develop a method of selection and 
                         component integration into the system in order to increase the 
                         reliability of the electronic component and the system in which it 
                         is integrated according to the intended mission. As a study case, 
                         it will be analyzed the behavior of COTS transistors exposed to 
                         ionizing radiation to demonstrate the affected parameters and 
                         their resistance to radiation, evaluating how they would behave in 
                         the space environment. Finally, the proposed method will be 
                         discussed in relation to the study case. Thus, with the correct 
                         use of the COTS component, it is possible to combine the benefit 
                         of using this component with adequate reliability and system life
