针对商用航空电子设备的高可靠性电路保护
TVS二极管在恶劣条件下为敏感的电子产品提供保护
过去50年的统计数据显示,商业航空旅行已经成为最安全、最可靠的交通方式之一。由于商业飞行的安全性不断提高,对先进的商用航空电子技术的需求也持续增长。2014年9月,Avascent预测全球商用航空电子设备市场将保持4.8%的增长速度,并将一直持续到2019年。该公司还预计2015年在固定翼商用飞机的商用航空电子系统上的花费将达到210亿美元。
从财务价值角度来讲,商用航空电子设备的最大细分市场有哪些?Lucintel公司的分析师对这些细分市场从大到小进行了排名:
1.通讯网络和导航
2.控制系统
3.雷达和监控
4.显示系统
除了以上列出的系统,先进的商用航空电子设备还包括转向系统、飞机传感器、着陆辅助系统、信息娱乐系统、先进的预警技术、带有LED显示的升级版驾驶舱、可检测剧烈颠簸或风切变的尖端的气象数据采集器以及分析常见问题的飞行记录仪。先进的跟踪和记录技术使得监管机构、飞行员和航空公司可以共享有关飞行危险的大量信息,从而提高商业飞行的可靠性和安全性。
增加的复杂性导致脆弱性增加
与大多数电子系统一样,商用航空电子的发展及其不断增长的复杂性都导致了脆弱性增加,如果不采取预防措施,风险也在所难免。添加复杂的航空电子设备意味着在飞机中创建更为隐蔽、更加复杂的电子系统。而且,航空电子系统越复杂,这些电子设备就越容易受到损坏。
航空电子系统会受到各种危险条件的影响,包括极端的压力和温度、雷电浪涌、静电放电和其他瞬变。对于位于隐藏面板内的电气系统,机组人员难以进行检查维护,会因过电压瞬变而导致损坏,从而使其失效或故障。航空电子系统故障可能会产生高昂的维修费用,或者直接需要更换设备。在最坏的情况下,一处故障可能会危及机组人员和乘客的生命安全。
TVS二极管提供高可靠性的电路保护
高可靠性的电路保护是保护先进的商用航空电子设备中敏感电子组件免遭灾难性事件的关键。采用正确的电路保护解决方案,不便于检查和维护的电气系统的运行安全性和可靠性可得以提升。
当今的设计工程师依靠瞬态电压抑制(TVS)二极管对商用航空电子设备进行保护。在诸如全权数字式发动机控制(FADEC)系统、飞机传感器、航空电子设备计算机、电子控制飞行控制系统、驾驶舱电子设备和机场着陆辅助系统的航空电子设备中,TVS二极管可提供直流电源保护和静电放电保护。选择这些硅雪崩器件的原因是它们快速的响应时间、低钳位电压、高浪涌能力和低漏电流。它们设计的目的是保护敏感的电子设备免受因雷击浪涌、静电放电和其他瞬变引发的电压瞬变。
选择TVS二极管制造商的秘诀
要为某个航空电子应用找到最佳的电路保护解决方案,设计工程师首先要甄别电路保护器件的可靠制造商。在寻找TVS二极管制造商时,需注意以下几个关键特征:
•为关键应用生产TVS二极管的专业技术
•在航空航天工业中使用的跟踪记录,确保了经市场考验的表现
•应对大量且不断增长的需求的灵活的生产能力
•无与伦比的应用方面专业技术和支持
•设计和合规性支持的测试和验证服务
•广泛的电路保护产品和解决方案
•全球产品供应网络
优质TVS二极管的主要特色功能
确定好制造商之后,设计工程师应该对该公司的产品系列中的TVS二极管的功能加以考虑。最重要的特点是用来确保只选择符合MIL-STD和JEDEC标准的所有严格的测试程序要求的TVS二极管的筛选和分拣过程。这一高度精确的过程保证了这些器件卓越的可靠性和性能。除了筛选和分拣,还应备有浪涌监测、高温反向偏压(HTRB)监测和电气监测分拣步骤。
对于灵活性,TVS二极管应使用以下两种方式之一进行生产:1)、成品筛选及B组试验应力,包括抗浪涌、老化(即HTRB)等,或2)、按照制造商内部要求的客制化筛选和分拣过程流程。理想的TVS二极管的封装为紧凑的SMB、SMC和SMD DO-214AA封装,峰值脉冲功率耗散的额定值为600到3000W之间。在符合RTCA/DO-160《机载设备环境条件和测试程序标准》的前提下,理想的TVS二极管还应便于设计。

结论
随着商业航空电子产业在产品安全性和可靠性方面持续发展,对复杂航空电子设备的需求也持续增长。与先进的航空电子产品需求增长随之而来的是对电路保护技术的需求,以及为这些复杂系统内部的敏感电气组件提供保护。
采用TVS二极管技术的恰当的电路保护,确保了飞机电子设备的安全性和完整性,保护着机组人员和乘客的生命安全。当今的设计工程师在选择产品时,应选择在关键应用TVS二极管方面具有专业技术、先进的检测服务和久经市场验证的表现的可靠电路保护制造商作为合作伙伴。预先筛选、预先分拣的具有紧凑封装的TVS二极管将为商用航空电子产品提供最为可靠的保护和性能。

浪涌保护器LSP05系列的热保护型浪涌保护器最大能抑制2KV到4KV的瞬变电压吗?
浪涌保护器LSP05系列符合IEC61643-11 ClassII的等级,要符合这个等级必须要通过6KV的脉冲实验(这是模拟雷击实验的过程),因此该系列通过了IC61643-11 classII的认证,可以满足应用要求。

瞬态抑制二极管(TVS)SP1001漏电流参数的意义是什么?
瞬态电压抑制二极管的漏电流是指PN结间在截止状态下流过的微弱电流,PN结上的漏电流是不可能避免的,因为PN结间只要有电子的存在就不可避免的会做无规则的运动,因而产生漏电流。
