Additional Details

The ESD5Z3.3 is typically packaged in a small surface-mount package such as SOD-523 or similar. It features a working voltage of 3.3V, making it suitable for protecting 3.3V logic circuits. The device is designed to meet industry-standard ESD immunity requirements, such as IEC 61000-4-2. This is a transient voltage suppression (TVS) diode. Its low capacitance makes it suitable for protecting high-speed data lines. It protects against contact discharge events.

Given its END-OF-LIFE status, it is advised to contact Weitron Technology or their authorized distributors to find suitable replacement options for new designs or ongoing projects.
