3 Description

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 ±30 kV per the IEC 61000-4-2

international standard (greater than Level 4).

The ultra-low dynamic resistance (0.13 Ω) and

extremely low clamping voltage (6.8 V at 16 A

TLP) ensure system level protection against transient

events. This device has a low capacitance of 0.9

pF IO capacitance making it suitable for protecting

interfaces such as USB 2.0 and Ethernet 10/100/1000

Mbps.

The ESD321 is offered in the industry standard 0402

(DPY/DFN1006P2) and SOD-523 (DYA) packages.
