Product details
Overview
TPD1E04U04DPYR from Texas Instruments is a unidirectional TVS ESD protection diode in X1SON (DPY) package, designed for HDMI 2.0 and USB 3.0 signal lines. It delivers ±16-kV IEC 61000-4-2 contact/air-gap ESD protection, 0.5-pF typical IO-to-GND capacitance, and ultra-low dynamic resistance (0.25 Ω IO→GND), enabling reliable 6-Gbps data integrity in set-top boxes, laptops, and monitors.
For engineers reviewing the TPD1E04U04DPYR datasheet, TPD1E04U04DPYR pinout, TPD1E04U04DPYR application, or TPD1E04U04DPYR equivalent, key selection criteria include clamping voltage at 16-A TLP (8.9 V), DC breakdown voltage (≥4.5 V), industrial temperature range (–40°C to +125°C), and compatibility with high-speed TMDS differential pairs requiring sub-0.65-pF line capacitance.
Technical Context
The TPD1E04U04DPYR implements a single-channel, unidirectional silicon avalanche diode structure optimized for fast transient suppression on high-speed I/O. Its low RDYN (0.25 Ω IO→GND / 0.18 Ω GND→IO) and ultra-low clamping voltage ensure minimal voltage overshoot during ±16-kV ESD events, preserving signal integrity on TMDS, USB 3.0, and DisplayPort 1.2 lines.
It operates passively within 0 V to 3.6 V signal range and supports full HDMI 2.0 bandwidth (up to 6 Gbps) due to its 0.5-pF typical capacitance and flat frequency response up to 10 GHz. The device triggers above 4.5 V breakdown and holds at 5.3 V, maintaining safe bias conditions for downstream SoCs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC 61000-4-2) | ±16-kV contact & air-gap discharge - meets Level 4 immunity without system-level failure |
| IO Capacitance | 0.5 pF (typ), 0.65 pF (max) - preserves HDMI 2.0 6-Gbps eye opening and insertion loss < –1 dB up to 6 GHz |

|---|---|
Use Scenario: Protecting TMDS differential pairs (D0+/D0–, D1+/D1–, D2+/D2–, CK+/CK–) on HDMI 2.0 source ports against human-body ESD events. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between HDMI connector and SoC PHY, diverting ESD current to ground before it reaches sensitive input circuitry. Use Value: Maintains 6-Gbps signal integrity with <0.65-pF loading and 8.9-V clamping, preventing bit errors and hot-plug detection failures. |
Use Scenario: Shielding USB 3.0 SuperSpeed differential lanes (SSTX+/SSTX–, SSRX+/SSRX–) from connector-based ESD in portable docking stations. IC Role / Device Role / Timing Role: Single-channel ESD suppressor per lane, positioned adjacent to USB Type-B or Type-C receptacle to minimize loop inductance. Use Value: Enables full 5-Gbps USB 3.0 operation with negligible insertion loss (<–0.5 dB @ 2.5 GHz) and no signal jitter increase. |
| DisplayPort 1.2 Source Interface | PCIe 3.0 Add-in Card Edge Connector |
Use Scenario: Securing DisplayPort 1.2 main link lanes (AUX CH, HPD, and 4 data lanes) on graphics card output headers. IC Role / Device Role / Timing Role: Per-lane ESD protection diode ensuring compliance with DP 1.2a electrical specifications under ±15-kV contact discharge. Use Value: Preserves 8.1-Gbps link training stability and reduces AUX channel timeout errors caused by transient-induced logic upset. |
Use Scenario: Adding ESD resilience to PCIe 3.0 x16 edge connector pins on server backplanes exposed to field maintenance handling. IC Role / Device Role / Timing Role: Discrete TVS per high-speed differential pair (TX/RX), mounted within 3 mm of connector to limit inductive impedance. Use Value: Prevents latch-up or gate oxide damage in PCIe root complex controllers during board insertion/removal, supporting 8 GT/s data rates. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD1E04U04DPLR | Same die, X2SON (DPL) 0.60 mm × 0.30 mm package - 30% smaller footprint, identical electrical specs | Preferred for ultra-dense layouts (e.g., mobile HDMI adapters); requires tighter stencil aperture and reflow profile validation | Select DPLR when board space is constrained and 0201-level assembly capability exists. |
| SMA6J33A-Q | Unidirectional 33-V standoff, 55-V clamping, 17-pF capacitance - higher voltage rating but 34× higher capacitance | Only suitable for low-speed control lines (DDC, CEC, HOTPLUG_DET), not TMDS or SuperSpeed data lanes | Use SMA6J33A-Q only for auxiliary signals where bandwidth <10 MHz; avoid for any >1-Gbps interface. |
Compared with TPD1E04U04DPYR, the DPLR offers identical protection performance in a smaller package but demands tighter process control, while SMA6J33A-Q provides higher surge tolerance at the cost of unusable capacitance for high-speed data - making TPD1E04U04DPYR the sole viable option for HDMI 2.0/USB 3.0 signal-line protection.

FAQ
What is the maximum data rate supported by TPD1E04U04DPYR?
TPD1E04U04DPYR supports data rates up to 6 Gbps, validated via HDMI 2.0 6-Gbps TP2 eye diagram testing with negligible degradation. Its 0.5-pF typical capacitance and flat frequency response up to 10 GHz ensure signal integrity on TMDS, USB 3.0, and DisplayPort 1.2 links. This performance is confirmed in TI's SLVSDG4B datasheet Figure 11 and Figure 12.
Does TPD1E04U04DPYR require external bias or power supply?
No, TPD1E04U04DPYR is a passive TVS diode and requires no external power or bias. It operates solely on transient voltage thresholds: triggering above 4.5 V breakdown and clamping at 8.9 V during 16-A ESD events. The device must be placed between the protected signal line and a low-inductance ground plane to function correctly.
Can TPD1E04U04DPYR protect bidirectional signal lines like HDMI TMDS pairs?
Yes, TPD1E04U04DPYR protects bidirectional high-speed differential signals such as HDMI TMDS lanes. Its unidirectional architecture (anode-to-GND) is applied per signal line - one device per conductor (e.g., TMDS_D0+ and TMDS_D0– each get their own TPD1E04U04DPYR). This configuration maintains signal symmetry and avoids DC path disruption.
What is the thermal resistance of TPD1E04U04DPYR in the DPY package?
The TPD1E04U04DPYR in X1SON (DPY) package has a junction-to-ambient thermal resistance (RθJA) of 683.6°C/W, junction-to-board (RθJB) of 568.7°C/W, and junction-to-case (top) of 494.2°C/W, per TI's SLVSDG4B datasheet Section 6.5. These values assume standard JEDEC 2-layer board conditions and confirm suitability for surface-mount applications without active cooling.
Is TPD1E04U04DPYR compliant with RoHS and REACH requirements?
Yes, TPD1E04U04DPYR is RoHS-compliant (lead-free, halogen-free) and REACH-conformant, as verified in TI's official packaging addendum. The device uses NiPdAu lead finish and carries MSL Level-1 rating (260°C peak reflow, unlimited floor life), meeting IPC/JEDEC J-STD-020 standards for modern SMT assembly processes.
