3 Description
The ESD751 and ESD761 are single-channel low
capacitance bidirectional ESD protection devices
for USB power delivery (USB-PD). These devices
are rated to dissipate contact ESD strikes beyond
the maximum level specified in the IEC 61000-4-2
international standard (±22-kV Contact, ±22-kV
Airgap) and (±15-kV Contact, ±15-kV Airgap),
respectively. The low dynamic resistance and low
clamping voltage help protect systems against
transient events. This protection is key because
industrial systems require a high level of robustness
and reliability.
