Product details

Its ultra-low capacitance of 0.5 pF at 1 MHz keeps signal integrity intact for HDMI interfaces, where capacitive loading directly impacts the eye diagram margin. The device clamps transients to 8.9 V maximum at a peak pulse current of 2.5 A (8/20 µs waveform), with a reverse standoff voltage of 3.6 V max.

This TVS comes in a 0402 (1006 Metric) body that reflows to a 2-X1SON (1x.60) supplier device package. The footprint is tiny — about 1.0 mm × 0.6 mm — so it fits comfortably on dense HDMI or USB-C boards. Orientation is unambiguous: the single unidirectional channel has a clear cathode mark.

For BOM planning, there is no LTB risk and no forced migration to a successor.

Frequently asked questions

Is TPD1E04U04DPYR suitable for HDMI 2.0?

Yes. The 0.5 pF capacitance is low enough to maintain signal integrity for HDMI 2.0 data rates (up to 18 Gbps). The steering (rail-to-rail) topology clamps to the supply rails, which is the standard protection for differential pairs. The part is explicitly listed for HDMI applications.

What is the capacitance of TPD1E04U04DPYR?

The capacitance is 0.5 pF, measured at 1 MHz. This ultra-low value is what makes the part suitable for high-speed interfaces like HDMI, USB 3.0, or Thunderbolt.
