3 Description
The ESD752 and ESD7x2 are bidirectional ESD
protection diodes for USB power delivery (USB-PD)
and industrial interfaces. The ESD752 and ESD7x2
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 ensures
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
ESD7x2 are suitable for protecting the slower speed
signals for USB power delivery and IO signals for
industrial applications.
The ESD752 and ESD7x2 are offered in two leaded
packages for easy flow through routing.
