Product details

0.5 pF capacitance — why it matters on HDMI lanes

Its 0.5 pF capacitance at 1 MHz is the headline number that decides fit for high-speed differential pairs: any added capacitance eats into the signal eye opening, and at HDMI 2.0 data rates (6 Gbps per lane) even 0.2 pF extra can close the margin. This part keeps the load low enough that it won't force a retimer or redriver in most HDMI 2.0 port designs.

The reverse standoff voltage is 3.6 V max, and clamping hits 8.9 V at the peak pulse current of 2.5 A (8/20 µs waveform). Peak pulse power is rated 16 W. For HDMI 2.0 or 2.1 source/sink protection, the 3.6 V standoff sits above the 3.3 V supply rail so the diode doesn't conduct during normal operation, but triggers fast enough to shunt a ±8 kV contact discharge (per IEC 61000-4-2) before the downstream IC sees damaging voltage. The 16 W rating is modest — it's sized for cable-discharge events, not direct lightning strikes.

The 0201 (0603 Metric) footprint — supplier device package 2-X2SON (0.6x0.3) — places the diode right at the HDMI connector pin, minimising stub inductance. Surface-mount assembly; the tape-and-reel or cut-tape option suits both prototype and volume pick-and-place.

Frequently asked questions

Can TPD1E04U04DPLR be used for HDMI 2.1 ESD protection?

The 0.5 pF capacitance is low enough for HDMI 2.1 data rates (12 Gbps per lane), but the 16 W peak pulse power and 2.5 A peak pulse current are modest. For HDMI 2.1, verify the system-level IEC 61000-4-2 target (typically ±8 kV contact) against the clamping voltage at the actual discharge current. In many designs this part works, but a higher-power device may be needed if the cable run is long or the enclosure lacks additional shielding.

Is TPD1E04U04DPLR suitable for HDMI 2.0?

Yes. The 0.5 pF capacitance and 3.6 V reverse standoff are well within HDMI 2.0 requirements. The rail-to-rail steering topology handles the 3.3 V supply rail cleanly, and the 0201 package fits directly at the connector for minimal parasitic inductance.

What is the cross reference or equivalent for TPD1E04U04DPLR?

For a pin-compatible alternative, compare other single-channel steering diodes in the 0201 package with ≤0.5 pF capacitance, such as parts from the same TI TPD1E family with different breakdown voltages. Verify the clamping voltage and peak pulse current against your system requirements before substituting.
