Texas Instruments ESD752 & ESD762 Dual ESD Protection Diodes

Texas Instruments ESD752 and ESD762 Dual ESD Protection Diodes are designed 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 (±30kV or ±20kV contact and ±30kV or ±20kV airgap). The low dynamic resistance and clamping voltage provide system-level protection against transient events. This protection is essential because industrial systems require high robustness and reliability.

The TI ESD752 and ESD762 dual ESD protection diodes 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 = 5.7A (8/20µs surge waveform) capability of the ESD752 is ideal for protecting USB VBUS against transient surge events and industrial I/O lines. Furthermore, the 3pF or 1.7pF line capacitance of the ESD752 and ESD762 is suitable for protecting the slower speed signals for USB power delivery and IO signals for industrial applications.

The ESD752 and ESD762 are housed in two leaded packages allowing easy flow through routing.
