Overview

The PESD5V0U2BT is a dual-channel bidirectional ESD protection diode designed to protect sensitive signal lines from electrostatic discharge events up to 10 kV. It features an ultra-low capacitance of 2.9 pF and a breakdown voltage of 5.5 V, making it suitable for high-speed data interfaces where signal integrity is critical.

Why Choose This Part

This device offers a very low diode capacitance of 2.9 pF to minimize signal attenuation and features a high ESD robustness reaching IEC 61000-4-2 level 4. Its bidirectional configuration allows for protection of signals that swing above and below ground without requiring multiple discrete components.

Applications

High-Speed Data Lines
Protection of dual bidirectional signal lines in computing and communication interfaces.
USB Interface Protection
Safeguards D+ and D- lines against ESD strikes while maintaining low signal distortion.
Portable Electronics
