ESD321 (ACTIVE)

1-Channel 30 kV ESD Protection Diode With Low Capacitance (< 1pF) in 0402 Package

 

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) package.
