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.
