Advance in Space Radiation Effects of Bipolar Transistors
Bipolar transistor has become the electronic component commonly used in aerospace vehicles due to their good current driving ability,low noise,good linearity and excellent matching characteristics.However,the bipolar transistor is prone to performance degradation in space radiation environment,further endangering the operation of the space equipment.In the work,the radiation damage effects of the bipolar transistor in space environment are summarized,including ionization damage,displacement damage and the irradiation synergistic effects of ionization damage and displacement damage.In the meanwhile,the performance degradation law and the damage mechanism of the bipolar transistor are analyzed.It can provide a reference for the long-term development of radiation resistance technology of bipolar transistor.
