3 Description

The ESD8x2 devices are bidirectional ESD protection

diodes for USB power delivery (USB-PD) and

industrial interfaces. The devices are rated to

dissipate ESD that meets or exceeds the maximum

level specified in the IEC 61000-4-2 standard

(±25kV contact and airgap, ±20kV contact and

airgap, or ±18kV contact and airgap). The low

dynamic resistance and low clamping voltage enables

system level protection against transient events. This

protection is key because industrial systems require a

high level of robustness and reliability.

These devices feature a low IO capacitance per

channel and a pin-out to suit two IO lines from

damage caused by electrostatic discharge (ESD)

and other transients. The IPP = 4.3A (8/20μs surge

waveform) capability of the ESD852 makes it an

excellent choice for protecting USB VBUS against

transient surge events as well as industrial I/O lines.

Additionally, the 2.8pF or 2.6pF line capacitance of

the ESD8x2 are an excellent choice for protecting the

slower speed signals for USB power delivery and IO

signals for industrial applications.
