3 Description

The ESD752 and ESD762 are bidirectional ESD

protection diodes for USB power delivery (USB-PD)

and industrial interfaces. The ESD752 and ESD762

are rated to dissipate contact ESD that meets

or exceeds the maximum level specified in the

IEC 61000-4-2 level 4 standard (±30-kV or ±20-kV

contact and ±30-kV or ±20-kV 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 = 5.7 A (8/20 μs surge

waveform) capability of the ESD752 makes it suitable

for protecting USB VBUS against transient surge

events as well as industrial I/O lines. Additionally, the

3 pF or 1.7 pF line capacitance of the ESD752 and

ESD762 are suitable for protecting the slower speed

signals for USB power delivery and IO signals for

industrial applications.

The ESD752 and ESD762 are offered in two leaded

packages for easy flow through routing.
