The device provides +\/-12kV IEC 61000-4-2 contact discharge and +\/-12kV air discharge protection on each channel. The key specification is the ultra-low capacitance of 0.2pF per channel, which makes it transparent to signals up to 10Gbps (USB 3.1 Gen 2, HDMI 2.0, DisplayPort 1.4). The bidirectional clamping structure means the diode can protect against both positive and negative ESD strikes without distorting the signal. During normal operation (signal swing between -0.3V and VBUS+0.3V), the protection diodes are reverse-biased and draw only leakage current (0.1nA typical). When an ESD event exceeds the clamp voltage, the TVS diode avalanches and shunts the ESD current to GND or VBUS. The dynamic resistance is only 0.25 ohm, which limits the clamping voltage to 7V at 12kV IEC strike (for a 5V VBUS system). The VBUS pin can be connected to the interface power supply (5V for USB 2.0, 3.3V for HDMI) to provide positive rail clamping. If VBUS is not connected, the positive clamp voltage defaults to approximately 6V. The USON-10 package is only 2.5 x 1.0mm, making it suitable for space-constrained designs like smartphones and tablets. The flow-through pinout (channels on opposite sides) simplifies PCB routing for high-speed differential pairs.","pin_description":"
