Texas Instruments ESD451 ±30kV ESD Protection Diode
Texas Instruments ESD451 ±30kV ESD Protection Diode is a bidirectional ESD protection diode for protecting data lines and other I/O ports. The ESD451 is rated to dissipate ESD strikes up to ±30kV per the IEC 61000-4-2 international standard (greater than Level 4). This device features a 0.5pF (typical) IO capacitance enabling high-speed interface protection for protocols such as USB 3.0. The extremely low dynamic resistance (0.19Ω) and clamping voltage (10.4V at 16A TLP) are specified for system-level protection against transient events.
The ±30kV ESD rating and 6.2A surge provide robust transient protection in a tiny package for protecting 5.5V power rails and data lines in portable electronics and other space-constrained applications such as wearables. The Texas Instruments ESD451 is offered in the industry standard 0201 (DPL) package.
