東芝推出適用於ThunderboltTM 3及其他高速訊號線的低電容TVS Diode

October 17, 2019

Toshiba Electronic Devices & Storage Corporation

DF2B5M4ASL,DF2B6M4ASL

東芝電子元件及儲存裝置株式會社(東芝)推出兩款低電容舜態電壓抑制二極體(TVS Deido)(ESD靜電放電保護二極體),兩款二極體均支援Thunderbolt 3、HDMI® 2.1和USB 3.1等高速通訊標準並已開始出貨。新推出的DF2B5M4ASL支援3.6V最大工作峰值反向電壓,而DF2B6M4ASL則支援5.5V。

平板電腦、筆記型電腦和遊戲機使用10Gbps或48Gbps高速通訊標準,可將視訊資料或大型檔案的傳輸時間盡可能縮短。隨著此類高速通訊中使用的控制IC逐漸縮小化,ESD容差也在下降,因此必須加強措施以因應ESD和連接器的突波;缺少這些措施可能導致嚴重故障,例如通訊錯誤和檔案損壞。

另外,連接到高速通訊線路的元件會對信號產生重大影響;印刷電路板上的電容器和電阻器等被動元件可能會使訊號波形失真。

其兩款產品利用適合高速通訊的低電容來減少這些影響。加上製程最佳化,新產品的電容(典型值)可達0.15pF,約比當前產品低25%[1] ,有助於在高速通訊中保持電路穩定。 

應用

  • 高速訊號線(平板電腦、筆記型電腦、遊戲機以及擴增實境和虛擬實境設備等)的ESD保護

產品特點

  • 總電容低:Ct = 0.15 pF(典型值)
  • 靜電放電額定電壓高[2]
  • VESD= ±16kV (DF2B5M4ASL)
    VESD= ±15kV (DF2B6M4ASL)
  • 小型表面黏著封裝:SL2(封裝代碼:SOD-962,0.62×0.32×0.3mm(典型值))
