ESD752DBZR

The ESD752 and ESD762 are bidirectional ESD protection diodes for USB power delivery (USB-PD) and industrial interfaces. The ESD752 and ESD762 are rated to dissipate contact ESD that meets or exceeds the maximum level specified in the IEC 61000-4-2 level 4 standard (±30 kV or ±20 kV contact and ±30 kV or ±20 kV 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 = 5.7 A (8/20 μs surge waveform) capability of the ESD752 makes it suitable for protecting USB VBUS against transient surge events as well as industrial I/O lines. Additionally, the 3 pF or 1.7 pF line capacitance of the ESD752 and ESD762 are suitable for protecting the slower speed signals for USB power delivery and IO signals for industrial applications. The ESD752 and ESD762 are offered in two leaded packages for easy flow through routing.
