AEC-Q101 Zener array for high-speed automotive data lines
Its standout characteristic is an ultra-low 0.25pF typical capacitance at 1MHz, which preserves signal integrity on high-speed differential pairs like USB 2.0, HDMI, and LVDS without degrading eye diagrams or adding jitter. The 3.6V reverse standoff voltage and 8.8V clamping at 2A (8/20µs pulse) protect 3.3V and 5V tolerant I/O from ESD and short-duration transients.
17W peak pulse — enough for automotive transients, not for mains surge
Rated at 17W peak pulse power (8/20µs waveform), this device handles the energy of typical automotive ESD strikes and load-dump residuals, but it is not designed for primary lightning or AC mains surge protection — the part explicitly lacks power line protection. The 2A peak pulse current at 8/20µs is sized for data-line protection where the source impedance is high and the energy is low. For a 3.3V rail, the 8.8V clamp gives roughly 2.6x headroom above the supply, which is tight for some transients but adequate when the TVS is placed close to the connector and the board has a low-inductance ground plane.
Package and footprint: 10-USON with 0.5mm pitch
The 10-UFDFN package (also designated 10-USON, 2.5mm x 1.0mm) has a 0.5mm lead pitch and an exposed thermal pad. The small footprint suits dense layouts where four independent ESD clamps replace discrete Zeners or larger TVS arrays. The supplier device package is 10-USON (2.5x1).
