Product details
Overview
TPD1E0B04DPYT from Texas Instruments is a single-channel bidirectional TVS ESD protection diode in X1SON (DPY) package, designed for ultra-high-speed signal lines including USB Type-C®, Thunderbolt™ 4, and 5GHz WiFi antenna interfaces. It delivers ±8kV IEC 61000-4-2 contact ESD protection, 0.15pF typical IO capacitance, 6.7V DC breakdown voltage, and operates across –40°C to +125°C.
For engineers reviewing the TPD1E0B04DPYT datasheet, TPD1E0B04DPYT pinout, TPD1E0B04DPYT application, or TPD1E0B04DPYT equivalent, this page provides verified electrical parameters, validated high-speed interface compatibility (up to 60Gbps), thermal metrics for DPY package, and real-world layout guidance for USB Type-C and antenna protection designs.
Technical Context
The TPD1E0B04DPYT implements a passive bidirectional clamping structure using silicon avalanche diodes optimized for sub-0.2pF line-to-ground capacitance. Its dynamic resistance of 1Ω ensures low-voltage clamping (7.2V at 1A TLP) during ESD transients while maintaining signal integrity on differential pairs up to 30GHz bandwidth.
It operates exclusively in clamping mode-triggering above ±6.7V breakdown and holding below 6.5V at 1mA-without bias or control signals. The DPY (X1SON, 1.00mm × 0.60mm) package enables placement within 2mm of USB Type-C connectors, minimizing stub inductance and preserving >30GHz -3dB insertion loss performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC 61000-4-2) | ±8kV contact / ±9kV air-gap discharge - meets Level 4 system-level immunity without external circuitry |
| IO Capacitance (DPY) | 0.15pF typical / 0.18pF max at 1MHz - enables clean 10Gbps+ eye diagrams with minimal signal distortion |
| DC Breakdown Voltage | ±6.7V typical - protects 3.3V/3.6V I/O rails while remaining inactive during normal operation |
| Clamping Voltage (1A TLP) | 7.2V (IO→GND) - limits transient overvoltage to safe levels for downstream USB PHY or RF transceiver inputs |
| Leakage Current | ≤10nA at ±2.5V - prevents DC loading on sensitive antenna matching networks or high-impedance CC lines |
| Surge Rating (IEC 61000-4-5) | 1.7A (8/20µs) - withstands lightning-induced surges on exposed USB or antenna ports |
| Operating Temperature | –40°C to +125°C - supports industrial and automotive cabin-temperature USB docking stations |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IO | ESD-protected signal line - connects directly to USB SSRX/SSTX, CC, SBU, or antenna feed point |
| 2 | GND | Low-inductance ground return - must connect to solid ground plane via shortest possible trace or multiple vias |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD1E0B04DPLR | Same die in smaller X2SON (DPL, 0.60mm × 0.30mm) package; 0.13pF typical capacitance | Better suited for space-constrained USB4 routing where trace length must be minimized | Select DPLR when PCB real estate is critical and layout allows tighter placement near connector |
| SMA6J33A-Q | Unidirectional 33V standoff, 500W surge rating, 350pF capacitance - higher power but much higher capacitance | Applicable only to low-speed DC-biased lines (e.g., VBUS, CC), not high-speed data lanes | Use SMA6J33A-Q only for non-signal-line protection; not a functional substitute for TPD1E0B04DPYT on USB/antenna paths |
Compared with TPD1E0B04DPLR, the TPD1E0B04DPYT offers slightly higher capacitance but superior thermal dissipation (RθJB = 162.5°C/W vs 394.4°C/W) and easier handling in small-batch assembly. Compared with SMA6J33A-Q, it provides 2,700× lower capacitance-making it the only viable option for 10Gbps+ interfaces.

FAQ
What is the maximum data rate supported by TPD1E0B04DPYT?
The TPD1E0B04DPYT supports interfaces up to 60Gbps aggregate bandwidth, as confirmed in the June 2025 datasheet revision. This capability stems from its 0.15pF typical capacitance and >30GHz -3dB insertion loss bandwidth, enabling clean signal transmission on USB4, Thunderbolt 4, and PCIe 5.0 differential lanes without measurable eye degradation.
Can TPD1E0B04DPYT be used on USB Type-C CC lines?
Yes, TPD1E0B04DPYT is rated for ±3.6V operating voltage and 10nA max leakage at ±2.5V, making it suitable for USB Type-C Configuration Channel (CC) lines. Its bidirectional clamping protects against both positive and negative ESD events on CC1/CC2, and its low leakage avoids interference with PD communication protocols.
What is the recommended PCB layout for TPD1E0B04DPYT in USB Type-C applications?
Place TPD1E0B04DPYT within 2mm of the USB Type-C connector, with direct short traces to both IO and GND pins. Use a solid ground plane beneath the device, connect Pin 2 (GND) to ground via ≥2 vias, and avoid routing unprotected signals parallel to protected traces. Follow TI's layout guidelines in Section 7.4 to minimize EMI coupling during ESD events.
Does TPD1E0B04DPYT require any external bias or control signals?
No, TPD1E0B04DPYT is a fully passive device with no power or control pins. It functions solely as a voltage-triggered bidirectional TVS diode, activating only when line voltage exceeds ±6.7V. No external components, biasing, or firmware configuration is needed-simplifying design and reducing BOM count.
How does TPD1E0B04DPYT compare to TPD1E0B04DPLR in thermal performance?
TPD1E0B04DPYT (X1SON) has significantly better thermal conduction than TPD1E0B04DPLR (X2SON): RθJB is 162.5°C/W versus 394.4°C/W. This means the DPY package dissipates heat more efficiently into the PCB, allowing sustained operation under repeated EFT bursts (80A, 5/50ns) without thermal derating in compact layouts.
