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 I PP = 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.
