瞬态抑制二极管,是一种二极管形式的高效能保护器件,正越来越广泛地用于宇航型号的电源电路及信号电路中以保护二级电源及信号电路。由于瞬态抑制二极管只有在电路出现异常的情况下才工作,应用过程中很难模拟电路异常,并且很难测出是否对后级电路造成了损伤,因此对宇航用该类器件进行充分的应用验证是非常必要的。本文研究了宇航用瞬态抑制二极管电性能应用验证方法,基于宇航型号中应用需求进行分析,设计了电性能验证的试验项目及试验方法,并按照本方法对北京微电子技术研究所生产的XX型瞬态抑制二极管进行了电性能应用验证,得出了对该器件电性能方面的全面评价。此方法也可推广至其它宇航用瞬态抑制二极管的应用验证工作。

Transient Voltage Suppressor (TVS), as an effective protective device in the form of diode, has found wider application in power circuits and signal circuits of aerospace models, which aims to protect secondary power and signal circuits. TVS only operates in case of circuit abnormality, which however is hard to be simulated, and it is also hard to measure whether such abnormality damages other circuits, thus it is necessary to carry out comprehensive application validation on such devices for aerospace applications. A validation method about the electrical performance of TVS for aerospace applications has been studied in the paper, which is analyzed based on application demands of aerospace models, and the test items and test method for electrical performance validation have been devised as well. Based on this method, the electrical performance of XX TVS manufactured by Beijing Microelectronics Technology Institute has been subjected to application validation, with a comprehensive evaluation on the electrical performance of the device achieved. This method can also be promoted in the application validation of other TVS for aerospace applications.

高等级宇航用瞬态抑制二极管的研制和生产技术难度较大,工艺要求高,目前国际上生产厂家主要集中在美国,主要有Microsemi和Sensitron等,产品已系列化生产,且生产自动化程度也较高,产品成品率和可靠性也很高,而国内关于高等级宇航用瞬态抑制二极管的研制工作起步较晚,目前完成研制的器件规格只有少数常用的几款,研制经验相对较少,产品的成熟度不够,产品可靠性存在隐患。而与此同时,长寿命卫星、载人航天工程、北斗导航、探月工程等多项航天工程并举,应用需求较大。为推动我国航天器用瞬态抑制二极管实现自主创新和跨越式发展,亟需对国产新研瞬态抑制二极管进行应用验证,充分验证器件的性能,以保证新研制器件在航天型号工程中的成功应用。

High-level TVS for aerospace applications involves sophisticated R&D and manufacturing technologies and higher demands on processing. Major manufacturers of such device are mainly located in the US, including Microsemi and Sensitron. Series manufacturing, which features higher automation, has been realized for this product, and its production yield and reliability are also very high. However, R&D for high-level TVS in China started late, with only several common models being researched and developed. The domestic production lacks R&D experience, product readiness and reliability. Yet, a number of aerospace engineering projects advance rapidly, including long-lived satellite, manned space flight project, Beidou navigation satellite system, and lunar exploration program, thus raising huger demand on this product. In order to boost the independent innovation and unbounded development of Chinese TVS for spacecraft, it is an urgent need to carry out application validation on the newly developed TVS in China, to comprehensively validate the performance of the device, thereby ensuring successful application of new devices in aerospace engineering.
