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.
