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.
