3 Description

The ESD401 is a bidirectional TVS ESD protection

diode featuring low RDYN and low clamping voltage.

The ESD401 is rated to dissipate ESD strikes

exceeding the maximum level specified in the IEC

61000-4-2 international standard (Level 4). The low

dynamic resistance (0.7Ω) to ensure system level

protection against transient events. This device

features a 0.77pF IO capacitance making it ideal for

protecting interfaces such as USB 2.0. The device

can operate with ultra-low leakage up to ±5.5V and

survive DC faults up to 8.3V.

The ESD401 is offered in the industry standard 0402

(DPY) package.
