Additional Details

The VESD05A1B-02Z is typically surface-mounted on a PCB near the protected component. The specific clamping voltage, capacitance, and other electrical characteristics can be found in the device's datasheet. Proper PCB layout is crucial for effective ESD protection. Keep trace lengths short and wide and place the TVS diode as close as possible to the connector or potential source of ESD.
