ESD451 - Texas Instruments

ESD451 1-Channel Bidirectional ESD Diode

The ESD451 is a bidirectional ESD protection diode for protecting data line and other I/O ports. The ESD451 is rated to dissipate ESD strikes up to ±30 kV per the IEC 61000-4-2 international standard (greater than Level 4). This device features a 0.5 pF (typical) IO capacitance enabling high-speed interface protection for protocols such as USB 3.0. The ext.
