Additional Details

The PACUSBVB-D2Y6R uses avalanche breakdown diodes to clamp transient voltages to a safe level, preventing them from reaching sensitive USB circuitry. The low clamping voltage ensures that the protected circuitry is not exposed to excessive voltages during an ESD event.

The low capacitance of the TVS diode array minimizes signal distortion and impedance mismatch on the USB data lines, preserving the signal integrity of high-speed USB data transmission. The fast response time ensures that the TVS diode array can quickly clamp transient voltages before they can damage the protected circuitry.

Consult the On Semiconductor (formerly California Micro Devices) datasheet for the PACUSBVB-D2Y6R for detailed specifications, including clamping voltage, capacitance, leakage current, and ESD protection levels. The datasheet also provides application notes and PCB layout recommendations to optimize ESD protection performance. Proper grounding and PCB layout are crucial for effective ESD protection.
