瞬態(tài)抑制二極管，是一種二極管形式的高效能保護(hù)器件，正越來越廣泛地用于宇航型號(hào)的電源電路及信號(hào)電路中以保護(hù)二級(jí)電源及信號(hào)電路。由于瞬態(tài)抑制二極管只有在電路出現(xiàn)異常的情況下才工作，應(yīng)用過程中很難模擬電路異常，并且很難測出是否對后級(jí)電路造成了損傷，因此對宇航用該類器件進(jìn)行充分的應(yīng)用驗(yàn)證是非常必要的。本文研究了宇航用瞬態(tài)抑制二極管電性能應(yīng)用驗(yàn)證方法，基于宇航型號(hào)中應(yīng)用需求進(jìn)行分析，設(shè)計(jì)了電性能驗(yàn)證的試驗(yàn)項(xiàng)目及試驗(yàn)方法，并按照本方法對北京微電子技術(shù)研究所生產(chǎn)的XX型瞬態(tài)抑制二極管進(jìn)行了電性能應(yīng)用驗(yàn)證，得出了對該器件電性能方面的全面評(píng)價(jià)。此方法也可推廣至其它宇航用瞬態(tài)抑制二極管的應(yīng)用驗(yàn)證工作。
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.
高等級(jí)宇航用瞬態(tài)抑制二極管的研制和生產(chǎn)技術(shù)難度較大，工藝要求高，目前國際上生產(chǎn)廠家主要集中在美國，主要有Microsemi和Sensitron等，產(chǎn)品已系列化生產(chǎn)，且生產(chǎn)自動(dòng)化程度也較高，產(chǎn)品成品率和可靠性也很高，而國內(nèi)關(guān)于高等級(jí)宇航用瞬態(tài)抑制二極管的研制工作起步較晚，目前完成研制的器件規(guī)格只有少數(shù)常用的幾款，研制經(jīng)驗(yàn)相對較少，產(chǎn)品的成熟度不夠，產(chǎn)品可靠性存在隱患。而與此同時(shí)，長壽命衛(wèi)星、載人航天工程、北斗導(dǎo)航、探月工程等多項(xiàng)航天工程并舉，應(yīng)用需求較大。為推動(dòng)我國航天器用瞬態(tài)抑制二極管實(shí)現(xiàn)自主創(chuàng)新和跨越式發(fā)展，亟需對國產(chǎn)新研瞬態(tài)抑制二極管進(jìn)行應(yīng)用驗(yàn)證，充分驗(yàn)證器件的性能，以保證新研制器件在航天型號(hào)工程中的成功應(yīng)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.
