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 (±25-kV
contact and airgap, or ±18-kV 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 (8/20 μs 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 2.8 pF or 2.6 pF 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.
