Product Attributes

Introduction

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.

Features
