The ESD851 is a bidirectional ESD protection diode designed for clamping harmful transients such as ESD and surge. The ESD851 is rated to dissipate ESD strikes up to ±30kV (contact and air gap discharge), which exceeds the maximum level specified in the IEC 61000-4-2 international standard (Level 4). For surges, the device can clamp 8/20µs surges with peak currents up to 6.5A in accordance with the IEC 61000-4-5 standard. This device also features a 4.3pF (typical) IO capacitance enabling it to protect data lines. The low dynamic resistance and low clamping voltage provides system level protection against transient events. The ESD851 is offered in the industry standard, leaded SOD-323 package to enable easy solderability.
