Technical Specifications:

The SESD0201X1UN-0020-090 typically features a standoff voltage around 2V, a breakdown voltage slightly above that, and a clamping voltage significantly lower than the surge voltage it is designed to protect against. The device is designed for high-speed data lines, maintaining signal integrity while providing robust ESD protection. It is typically packaged in a small form factor suitable for dense PCB layouts.

Detailed specifications include parameters like reverse standoff voltage (VRWM), breakdown voltage (VBR), clamping voltage (VC), peak pulse current (IPP), and capacitance. Consult the datasheet for precise values and application guidelines to ensure proper circuit protection.
