This paper analyzes the magnetic field coupling from System Generated Electromagnetic Pulse (SGEMP) in terminal protection devices (TPD's) to non-interface or buried circuits of spacecraft electronics boxes. The analysis approach is outlined and results obtained from a computer based solution of the analysis are presented along with test data collected to empirically verify the analysis. Finally an example is provided in which the analysis results are used to calculate the energy coupled to a buried circuit so that a comparison of known device pulse burn out levels can be made. This technique provides an assessment of device susceptibility to the induced fields for representative circuit board trace layouts.
