PESD2USB3UV-TR High-Speed ESD Protection Array (3.3V, 1pF)

When designing custom DIY electronics with exposed external ports, your fragile 3.3V microcontrollers are just one static shock away from permanent damage. The PESD2USB3UV-TR is a specialized Transient Voltage Suppressor (TVS) array engineered specifically for safeguarding high-speed data lines. Standard ESD diodes have a high internal capacitance that acts as a low-pass filter, destroying high-frequency signals. This premium chip solves that problem with a low capacitance of just 1pF, ensuring that fast digital communications—like USB 2.0, USB 3.0, and high-speed UART/SPI—remain crisp and completely distortion-free.

Optimized strictly for modern 3.3V logic systems, it provides a much tighter protection threshold compared to generic 5V TVS diodes. The moment a dangerous electrostatic discharge occurs from plugging in a cable or human contact, this microscopic array instantly clamps the voltage and shunts the destructive energy safely to ground. It is an indispensable, professional-grade shield for securing the data pins on your Raspberry Pi Pico, STM32, or ESP32-based custom development boards.

Key Features:

• Low Capacitance (1pF): Preserves high-speed signal integrity, making it ideal for protecting USB data lines and fast differential pairs without degrading the signal.

• 3.3V Logic Optimized: Perfectly matched for modern low-voltage microcontrollers, offering precise overvoltage clamping exactly where 3.3V chips need it.

• Bulletproof ESD Defense: Instantly reacts to high-voltage electrostatic strikes, saving expensive processors and transceivers from sudden electrical death.

• Multi-Line Shielding: Simplifies your PCB layout by protecting multiple data lines simultaneously with a single, highly compact surface-mount component.
