3 Description

The ESD562-Q1 is a bidirectional ESD protection diode for battery management systems and other automotive applications. The ESD562-Q1 is rated to dissipate ESD strikes beyond the maximum level specified in the IEC 61000-4-2 international standard (±22kV Contact/Air-gap). The device can clamp 8/20μs surges with peak pulse currents up to 3A in accordance with the IEC 61000-4-5 standard.

This device features a 1.5pF (typical) IO capacitance enabling high-speed interface protection. The low clamping voltage in the positive and negative direction help protect systems against transient events. This protection is key in automotive systems that require a high level of robustness.

The ESD562-Q1 is available in a small leaded SOT-23 (DBZ) package.
