Texas Instruments ESD8x2 2-Channel, 36V ESD Protection Diodes
Texas Instruments ESD8x2 2-Channel, 36V ESD Protection Diodes are designed for USB power delivery (USB-PD) and industrial interfaces. The bidirectional ESD protection diodes are rated to dissipate ESD that meets or exceeds the maximum level specified in the IEC 61000-4-2 standard (±25kV contact and airgap, or ±18kV contact and airgap). The low dynamic resistance and clamping voltage allow system-level protection against transient events. This protection is ideal for industrial systems that need a high level of robustness and reliability.
The TI ESD8x2 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 = 4.3A (8/20µs surge waveform) capability of the ESD852 makes it excellent for protecting USB VBUS against transient surge events and industrial I/O lines. Additionally, the 2.8pF or 2.6pF line capacitance of the ESD8x2 protects the slower speed signals for USB power delivery and IO signals for industrial applications.
