The ESD652-Q1 is a bidirectional ESD protection diode for battery management systems and other automotive applications. The ESD652-Q1 is rated to dissipate ESD strikes beyond the maximum level specified in the IEC 61000-4-2 international standard (±30kV Contact, ±30kV Air-gap). The device can clamp 8/20µs surges with peak pulse currents up to 5.5A in accordance with the IEC 61000-4-5 standard. This device features a 4pF (typical) IO capacitance enabling high-speed interface protection. The low dynamic resistance and low clamping voltage help protect systems against transient events. This protection is key as automotive systems require a high level of robustness and reliability when they control safety devices. The ESD652-Q1 is available in a small leaded SOT-23 (DBZ) package.
