靜電ESD抑制器，亦稱為：靜電放電抑制器、ESD靜電保護管、ESD二極管、ESD、TVS二極管陣列、瞬態(tài)抑制二極管陣列、瞬變電壓抑制二極管陣列等等，當然也有電子工程師習慣稱為TVS二極管、TVS、TVS管，不管其名稱叫法如何多種多樣，其作用都是一樣的。ESD靜電抑制器，主要用于各類通信端口靜電防護，低結電容、低功率、小體積，其工作電壓一般都是根據IC電壓設計。ESD廠家東沃電子（DOWOSEMI）推出的靜電ESD抑制器工作電壓主要有：2.5V、2.8V、3.3V、5V、6V、7V、8V、12V、15V、18V、24V、36V等等。接下來，ESD保護器件廠家東沃電子（DOWOSEMI）要科普的是：DWNC9D5V1BA。

DWNC9D5V1BA描述

查閱東沃電子（DOWOSEMI推出的DWNC9D5V1BA產品手冊可知：The DWNC9D5V1BA is designed to protect voltage sensitive components from damage or latch-up due to ESD. Excellent clamping capability, low leakage, and fast response time provide best in class protection on designs that are exposed to ESD for board level. Because of its small size and bi-directional design, it is ideal for use in cellular phones, MP3 players, and portable applications that require audio line protection.
