Texas Instruments ESD851/ESD851-Q1 ESD Protection Diode

Texas Instruments ESD851/ESD851-Q1 Bidirectional ESD Protection Diode is designed to clamp harmful transients such as ESD and surge. The ESD851/ESD851-Q1 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 following 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 provide system-level protection against transient events. The Texas Instruments ESD851/ESD851-Q1 is offered in the industry standard, leaded SOD-323 package to enable easy solderability. The ESD851-Q1 devices are AEC-Q100 qualified for automotive applications.
