Product details
Overview
TPD2E2U06DCKR from Texas Instruments is a dual-channel TVS diode ESD protection device in SC70-3 package, designed for USB 2.0 data lines (D+ and D−). It delivers ±25 kV contact / ±30 kV air-gap IEC 61000-4-2 ESD protection, 1.5 pF typical line capacitance, 6.5 V minimum DC breakdown voltage, and 10 nA max leakage at 2.5 V - enabling high-speed signal integrity in portable USB interfaces.
For engineers reviewing the TPD2E2U06DCKR datasheet, TPD2E2U06DCKR pinout, TPD2E2U06DCKR application, or TPD2E2U06DCKR equivalent, this page provides verified technical context, validated pin functions, USB 2.0–specific implementation guidance, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The TPD2E2U06DCKR implements a symmetric dual-diode architecture per channel, with bidirectional clamping between each I/O pin and GND. Its low dynamic resistance (0.6 Ω IO-to-GND, 0.4 Ω GND-to-IO in DCK package) ensures sub-12.4 V clamping at 5 A TLP pulse, limiting transient stress on downstream USB transceivers.
It operates passively across –40°C to +125°C with no bias required, leveraging silicon avalanche diodes optimized for fast response (<1 ns) and minimal parasitic capacitance. The SC70-3 footprint supports flow-through routing directly at USB connectors, minimizing stub length and preserving 480 Mbps signal fidelity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC 61000-4-2) | ±25 kV contact / ±30 kV air-gap - meets Level 4 immunity for handheld and portable USB endpoints |
| Line Capacitance | 1.5 pF (typ) - preserves USB 2.0 eye diagram integrity up to 480 Mbps without equalization |
| DC Breakdown Voltage | 6.5 V (min) - safely tolerates 5.5 V USB VBUS-coupled transients while protecting 3.3 V logic |
| Leakage Current | 10 nA (max) at 2.5 V - negligible loading on I²C or USB pull-up/pull-down networks |
| Clamping Voltage | 9.7 V at 1 A TLP - limits peak stress on USB PHY I/O during ESD events |
| Surge Current | 5.5 A (8/20 µs) - handles IEC 61000-4-5 induced surges near external ports |
| Operating Temperature | –40°C to +125°C - supports industrial and automotive-adjacent USB host/device applications |
Pinout & Package
TPD2E2U06DCKR uses the SC70-3 (DCK) package: 2.0 mm × 1.25 mm body, 1.1 mm max height, 0.65 mm pitch, with gull-wing leads. Pin 1 = IO1, Pin 2 = IO2, Pin 3 = GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (IO1) | I/O protection channel | Connects to one high-speed signal line (e.g., USB D+); bidirectionally clamps ESD to GND |
| Pin 2 (IO2) | I/O protection channel | Connects to second high-speed signal line (e.g., USB D−); electrically identical to IO1 |
| Pin 3 (GND) | Reference terminal | Low-inductance ground return path for ESD current; must connect to system ground plane near connector |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel symmetry | Identical IO1/IO2 channels enable flexible D+/D− assignment without performance trade-off |
| Ultra-low capacitance | 1.5 pF typ ensures <0.5 dB insertion loss at 240 MHz - critical for USB 2.0 full-speed compliance |
| Bidirectional clamping | Clamps both positive and negative transients to GND without polarity constraints on signal lines |
| Flow-through layout | SC70-3 pinout allows in-line routing between connector and PHY - eliminates vias or stubs |
| Industrial temperature range | Validated operation from –40°C to +125°C supports deployment in set-top boxes, servers, and EPOS terminals |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DCKR | Single-channel, 1.0 pF capacitance, 5.5 V breakdown - lower capacitance but half the channel count | Requires two devices for USB D+/D−; better for space-constrained single-line protection | Select when protecting isolated I²C or UART lines where dual-channel integration isn't needed |
| ESD5451D05R | Single-channel, 0.6 pF capacitance, 5.5 V breakdown, SOD-523 package - smaller footprint, lower CL | Not pin-compatible; requires PCB redesign; optimized for ultra-high-speed (>5 Gbps) interfaces | Choose for next-gen USB 3.x or PCIe Gen1 signal lines where 1.5 pF is marginal |
Compared with TPD2E2U06DCKR, TPD2E001DCKR offers lower capacitance per channel but doubles component count and assembly cost for USB 2.0, while ESD5451D05R enables higher-frequency use cases but sacrifices drop-in replaceability and dual-channel integration.

FAQ
What is the primary function of the TPD2E2U06DCKR?
The TPD2E2U06DCKR is a dual-channel transient voltage suppression (TVS) diode designed exclusively for electrostatic discharge (ESD) protection of high-speed data lines. It clamps ESD transients to safe voltage levels using bidirectional avalanche diodes between each I/O pin and ground, without requiring external power or control signals. Its role is purely passive surge diversion - not signal conditioning or level shifting.
Does the TPD2E2U06DCKR require a power supply or bias voltage to operate?
No, the TPD2E2U06DCKR is a fully passive device with no power pins or bias requirements. It operates solely through its internal silicon avalanche diode structure, triggering only when voltage across an I/O-to-GND path exceeds the breakdown threshold (~6.5 V). This eliminates design complexity, quiescent current concerns, and compatibility issues with unpowered or hot-plug interfaces like USB.
Can the TPD2E2U06DCKR be used for USB 3.0 or higher-speed interfaces?
The TPD2E2U06DCKR is not recommended for USB 3.0 (5 Gbps) or faster interfaces. Its 1.5 pF typical capacitance introduces measurable insertion loss above 1 GHz, and its clamping behavior has not been characterized for SuperSpeed differential signaling. TI explicitly positions it for USB 2.0 (480 Mbps), LVDS, and I²C - applications where 1.5 pF loading remains within acceptable signal integrity margins.
How does the TPD2E2U06DCKR differ from the automotive-grade TPD2E2U06-Q1?
The TPD2E2U06-Q1 is the AEC-Q100 qualified variant of the same silicon die, with identical electrical specifications (capacitance, clamping voltage, ESD rating) but extended reliability validation for automotive environments - including temperature cycling, humidity testing, and zero-defect screening. The TPD2E2U06DCKR is rated for industrial temperature range (–40°C to +125°C) and lacks automotive qualification documentation or lot traceability requirements.
What is the recommended PCB layout practice for the TPD2E2U06DCKR?
TI specifies placement of the TPD2E2U06DCKR as close as possible to the protected connector - ideally within 5 mm - with direct, short, low-inductance traces from IO1/IO2 to the connector pins and a dedicated low-impedance GND connection to the nearest ground plane via multiple vias. Avoid routing unprotected traces near the protected path, and eliminate sharp corners to reduce EMI coupling during ESD events.
