The ESD321 is a uni-directional TVS ESD protection diode featuring low dynamic resistance and low clamping voltage. The ESD321 is rated to dissipate ESD strikes up to ±30kV per the IEC 61000-4-2 international standard (greater than Level 4).

The ultra-low dynamic resistance (0.13Ω) and extremely low clamping voltage (6.8V at 16A TLP) ensure system level protection against transient events. This device has a low capacitance of 0.9pF IO capacitance making it suitable for protecting interfaces such as USB 2.0 and Ethernet 10/100/1000Mbps.

The ESD321 is offered in the industry standard 0402 (DPY/DFN1006P2) and SOD-523 (DYA) packages.

開發板

ESDEVM — 適用於 ESD 二極體封裝的通用評估模組,包括 0402、0201等

靜電敏感裝置 (ESD) 評估模組 (EVM) 是我們大多數 ESD 產品組合的開發平台。此電路板配備所有傳統 ESD 元件封裝,可測試任意數量的裝置。裝置可以焊接到其相應的元件封裝上,然後進行測試。對於一般高速 ESD 二極體,會實作阻抗控制的配置以取得 S 參數並取消內嵌電路板軌跡。對於非高速 ESD 二極體,其元件封裝會包含連接至測試點的軌跡,讓您輕鬆執行 DC 測試,例如崩潰電壓、保持電壓、洩漏等。電路板配置也可以透過將訊號針腳短路到訊號所在的任何地方,讓任何裝置針腳都能輕鬆地連接到電源 (VCC) 或接地。
