Product details

0.27 pF — the signal-integrity number that decides the fit

The TPD4E02B04DQAR is a four-channel Zener-type TVS diode array from Texas Instruments, packaged in a 10-USON (2.5x1 mm) footprint. Its 0.27 pF typical capacitance at 1 MHz is the headline parameter for HDMI port protection — low enough to keep the TMDS differential pair eye diagram open at 6 Gbps (HDMI 2.0) and 12 Gbps (HDMI 2.1) without adding measurable jitter.

Bidirectional clamping at 3.6 V standoff

Each of the four bidirectional channels clamps at 8.8 V typical peak pulse current (5 A, 8/20 µs waveform), with a reverse standoff of 3.6 V max. Peak pulse power is rated at 17 W, sized for IEC 61000-4-2 level 4 ESD strikes (8 kV contact, 15 kV air) common on HDMI connector pins. The 10-USON package with a 0.50 mm pitch keeps the trace stub short — critical for maintaining the controlled 100 Ω differential impedance on the HDMI lane.

Frequently asked questions

What is the capacitance of TPD4E02B04DQAR?

The typical capacitance is 0.27 pF measured at 1 MHz. This low value keeps the signal eye open for HDMI 2.0 and 2.1 data rates without degrading the differential impedance.

Is TPD4E02B04DQAR suitable for HDMI 2.0 or HDMI 2.1?

Yes. The 0.27 pF capacitance and 3.6 V standoff are within the HDMI 2.0 and 2.1 TMDS electrical requirements. The four bidirectional channels map directly to the four differential pairs (three data, one clock) in a standard HDMI port.

What is the difference between TPD4E02B04DQAR and TPD4E02B04?

TPD4E02B04 is the base product number for the family. The DQAR suffix specifically identifies the 10-USON (2.5x1 mm) package variant supplied on Tape & Reel. The silicon and electrical specifications are identical across the family.
