What the 0.3 pF capacitance means for high-speed signal lines
The D5V0X1BA2LP-7B: When a transient exceeds the breakdown threshold, the diode clamps at 17 V max while conducting a peak pulse current of 4 A (10/1000 µs waveform). Its capacitance is just 0.3 pF at 1 MHz — low enough to leave the signal integrity of USB 2.0, HDMI, or gigabit Ethernet lanes intact. The diode adds negligible loading to the data line, so it can be placed directly at the connector without degrading the eye diagram.
Package and board-fit: X1-DFN1006-2 (0402 footprint)
Housed in a 0402 (1006 Metric) surface-mount package with supplier device package X1-DFN1006-2, the diode occupies minimal PCB real estate and is compatible with standard pick-and-place assembly. The 0402 footprint makes it suitable for space-constrained designs such as mobile devices, wearables, and compact I/O modules.
The wide thermal margin means it can be placed near hot components or in outdoor equipment without derating concerns. The device is marked as general-purpose and does not include power line protection (no internal series element), so it is intended for signal-line ESD clamping rather than DC rail suppression.
