ESD652DBZR

ESD652 is a bidirectional ESD protection diode designed for battery management systems and other communication line protection. The ESD652 is rated to dissipate ESD strikes exceeding the highest level specified by the IEC 61000-4-2 international standard (±30kV contact discharge, ±30kV air discharge). The device can clamp 8/20μs surge peak pulse currents up to 5.5A per IEC 61000-4-5. With a typical IO capacitance of 4pF, the device enables high-speed interface protection. Low clamping voltage in both positive and negative directions helps protect the system from transient events. This protection is critical for industrial systems requiring high robustness and reliability. The ESD652 is available in a compact leaded SOT-23 (DBZ) package. The ESD652 is a diode-type TVS that provides a ground discharge path for transient voltage spikes such as ESD or surge on signal and power lines, requiring the device to be connected in parallel with the downstream circuit being protected. When transient current flows through the device, only a small voltage drop exists across the diode — this voltage is what gets applied to the protected IC. The low R_DYN of the triggered TVS keeps the clamping voltage V_CLAMP at a safe level for the protected IC.
