3 Description
ESD762 is a bidirectional ESD protection diode
for USB power delivery (USB-PD) and industrial
interfaces. ESD762 is rated to dissipate contact ESD
that meets or exceeds the maximum level specified in
the IEC 61000-4-2 level 4 standard (±18kV contact
and ±18kV 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 = 2.5A (8/20μs surge
waveform) capability of the ESD762 makes it suitable
for protecting USB VBUS against transient surge
events as well as industrial I/O lines. Additionally, the
1.7pF line capacitance of the ESD762 is suitable for
protecting the slower speed signals for USB power
delivery and IO signals for industrial applications.
The ESD762 are offered in the SOT-23 package for
easy flow through routing.
