新增的SOT-23封裝浪湧保護齊納二極體產品線擴展有助於電子設備品質改善

產品新聞2022年6月

東芝電子元件及儲存裝置株式會社(“東芝”)推出SOT-23封裝產品,擴充了“MKZ系列” 齊納二極管產品線。 齊納二極體可防止電子器件受開關浪湧[1]以及ESD(靜電放電)[2] 的影響。

機械式繼電器或電機工作時,線圈反電動勢會產生浪湧。 新品齊納二極體可防止電子器件受開關浪湧和ESD的影響。 此外,與現有系列產品一樣,新產品具有低動態電阻和低鉗位電壓特性,可以有效的吸收浪湧,抑制電子器件上的浪湧電壓,有助於提高電子設備的品質。 採用了通用SOT-23封裝的十款產品,齊納電壓覆蓋範圍5.6V至36V(典型值),支援大多數電壓,可用於各種電壓規格和安裝區域。

注:

[1]@IEC61000-4-5,tp=8/20μs脈衝

[2]@IEC61000-4-2

應用

  • 消費類設備(家用電器,電源等)
  • 工業設備(辦公自動化設備,電源等)

特性

  • 防止微秒級到毫秒級脈衝寬度浪湧電壓的影響。
  • 低動態電阻和低鉗位電壓
  • 寬齊納電壓產品線:VZ(典型值)=5.6V至36V
