Abstract： The paper is introducing the surge suppression circuit of a star sensor briefly. According to the design methods existing of surge suppression circuit, a component parameter analysis and calculation method with the best circuit performance is proposed. Starting with the stable realization of the circuit function and the electromagnetic compatibility of the circuit, this paper analyzes the selection and analysis of the key devices in the surge suppression circuit. Through theoretical analysis and experimental simulation, it is proved that the device selection obtained by the compatibility analysis idea proposed in this paper is effective and correct under the given design conditions. At the same time, it provides a reference for the surge suppression design of other subsystems, so as to improve the reliability of the whole on-board electronic equipment.
