【经验】解析GDT放电管的特点及选型注意事项
为提高电子产品的可靠性、稳定性等，电子工程师们通常都会在电路中添加ESD防护器件产品来降低电子产品的辐射干扰及浪涌问题。本文优恩将为我们介绍ESD防护器件——GDT放电管的特点及选型注意事项。
GDT放电管是一种开关型器件，主要将雷击浪涌电流导入大地，通常与MOV压敏电阻串联使用，阻断其漏电流，常用于信号避雷器的第一级泄放浪涌电流。 由于响应速度慢，第二级也用于限压保护。
GDT放电管的优点是电流流通能力大；寄生电容小；残压低，因此对高频电子电路的保护具有明显优势。其缺点为：放电延迟大，动作灵敏度不够理想，响应速度较慢，同时伴有续流电流，难以有效抑制上升陡度大的雷电波头，不利于交流或20V以上线路的保护。因此，GDT放电管一般用于防雷工程应用中，且多与限压避雷器配合使用。
对于GDT放电管选型，我们有以下几项需注意：
一、不能直接用在电源上进行差模保护；
二、击穿电压应大于线路上的最大信号频率电压；
三、耐受电流不应小于线路上可能出现的最大异常电流；
四、冲击击穿电压必须小于被保护线路的电压。

【经验】GDT放电管与MOV压敏电阻串联使用时是否导通在前？
GDT放电管与压敏电阻两个器件串联时，通常小容量的分压较高，大容量的分压较小，MOV压敏电阻的寄生电容是陶瓷气体放电管的百倍，因此绝大部分的电压会给到放电管，放电管导通之后，再施加到压敏电阻上，此时压敏电阻就会导通。

DC24V电源端口浪涌保护
DC24V电源端口浪涌保护DC24V电源是一种为设备提供稳定、可靠的直流电压输出的电源，其广泛应用于工业自动化控制系统。此方案设计为多级保护的方式，初级采用通流能力较强的陶瓷气体放电管和压敏电阻组合来承受泻放大的浪涌电流，中间使用电感做退耦，次级选用响应电压精准、稳定且快速的TVS管做保护，能有效抑制各类浪涌过电压，使后端的DC芯片及电路得到全面的保护。
解析TSS半导体放电管基本概念以及特征表现
本文中优恩半导体将为大家简要解析TSS半导体放电管基本概念以及特征表现。半导体放电管，简称TSS，也有很多人称为固体放电管，它主要应用场景在于信号线路的雷击浪涌防护。TSS半导体放电管与常见的几种放电管（GDT陶瓷气体放电管、SPG玻璃放电管）有所不同，它是一种利用晶闸管原理制成的过压保护器件，主要依靠PN结的击穿电流触发器件的导通和放电。
【技术】TVS管被击穿后的失效模式有哪些？
TVS(瞬态抑制二极管)可有效防护电路遭受瞬态浪涌电压及电流的危害。但它一旦被击穿，可能出现的现象一般有哪些？今天优恩半导体来为大家讲解。GDT放电管、TSS放电管、压敏电阻等电子元件是现如今在电子电路防护中用的比较多的几种过压保护器件，其应用领域十分广泛。
