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.
