產品新聞2022年7月
東芝電子元件及儲存裝置株式會社(“東芝”)推出“CSLZ系列”齊納二極管,可保護半導體器件,避免受開關浪湧/感應雷電浪湧 [1] ,以及靜電放電(ESD)[2] 的影響。 本產品線有10款產品,齊納電壓覆蓋範圍5.6V至30V(典型值)。
新品齊納二極體可防止半導體器件受奈秒級ESD[2] ,微秒級到毫秒級開關浪湧,以及接近直流的過壓脈衝的影響。 產品在東芝齊納二極管首次採用超小型SOD-962[3]封裝,安裝面積為0.1984mm2(典型值),與東芝目前採用SOD-523 [5] 封裝的產品[4]相比,佔位面積減小約85%,允許在設備上進行高密度打件。 產品有助於有效利用電路板,提高設備可靠性。
