Product details
Overview
TPD2E2U06QDCKRQ1 from Texas Instruments is an AEC-Q101-qualified automotive dual-channel TVS ESD protection diode array in SC70 (DCK) package, featuring 1.5-pF typical line capacitance, ±25-kV IEC 61000-4-2 contact ESD rating, 6.5-V minimum DC breakdown voltage, and ultra-low 10-nA max leakage current - deployed for high-speed USB 2.0 and LVDS interface protection in head units and telematics modules.
For engineers reviewing the TPD2E2U06QDCKRQ1 datasheet, TPD2E2U06QDCKRQ1 pinout, TPD2E2U06QDCKRQ1 application, or TPD2E2U06QDCKRQ1 equivalent, key selection criteria include low-capacitance signal integrity preservation, automotive-grade reliability across –40°C to +125°C, validated ISO 10605/IEC 61000-4-2 clamping performance, and SC70 footprint compatibility with space-constrained PCB layouts.
Technical Context
The TPD2E2U06QDCKRQ1 implements a dual-channel bidirectional TVS diode architecture with symmetrical I/O pins (IO1, IO2) referenced to GND, enabling simultaneous protection of differential or independent signal lines without polarity constraints. Its clamping action triggers above 6.5 V (VBR min) and limits transient voltages to ≤9.7 V at 1-A TLP pulse, ensuring downstream ICs remain within safe operating margins during ESD events.
Designed specifically for high-speed interfaces, it maintains 1.5-pF typical capacitance per channel and <0.1-pF channel-to-channel cross-coupling, supporting data rates beyond 1.5 Gbps while minimizing insertion loss up to 1 GHz. The device operates passively with no power supply required and relies solely on internal diode conduction paths to shunt ESD energy to ground.
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 automotive infotainment ports |

Pinout & Package
TPD2E2U06QDCKRQ1 is housed in a 3-pin SC70 (DCK) package with flow-through pin arrangement optimized for minimal trace length between connector and protected IC. Pin 1 (IO1) and Pin 2 (IO2) serve as symmetrical, bidirectional ESD-protected I/O channels; Pin 3 (GND) provides the low-inductance return path essential for effective transient suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IO1 (Pin 1) | Protected I/O channel | Bidirectional ESD clamp path for first high-speed signal line (e.g., USB D+ or LVDS+) |
| IO2 (Pin 2) | Protected I/O channel | Identical to IO1 - supports second signal line (e.g., USB D− or LVDS−) with matched capacitance |
| GND (Pin 3) | Ground reference | Low-impedance return node for ESD current; must connect directly to solid ground plane |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use including HBM ±10 kV and CDM ±1 kV testing per AEC Q100-002/Q100-011 |
| Low dynamic resistance (RDYN) | 0.6 Ω (IO→GND) - minimizes clamping voltage rise during high-current ESD pulses |
| Channel-to-channel isolation | 0.02 pF cross-capacitance - prevents crosstalk between protected differential pairs |
| Flow-through layout | Pins 1–2–3 alignment enables straight PCB trace routing from connector to IC without vias or bends |
| Thermal performance | RθJB = 89.2°C/W (DCK) - supports reliable operation under sustained surge conditions in compact layouts |
Applications
| USB 2.0 Interface Protection | LVDS Display Link Protection |
|---|---|
|
Use Scenario: Protecting USB 2.0 data lines (D+/D−) in automotive head units against ESD from user touch or cable handling. IC Role / Device Role / Timing Role: Dual-channel passive TVS diode array placed adjacent to USB connector to clamp transients before reaching USB transceiver.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001QDBZRQ1 | Single-channel, 0.6-pF capacitance, lower ESD rating (±12-kV IEC contact) | Limited to single-line protection; insufficient for differential USB/LVDS | Select only when protecting isolated low-capacitance lines where dual-channel capability is unnecessary |
| SMA6J5.0A-Q | Single-channel SMA package, 500-pF capacitance, higher power rating (600 W) | Too high capacitance for USB 2.0; suited for DC power rail or low-speed analog protection | Use only for non-high-speed applications where bandwidth is not constrained |
Compared with TPD2E2U06QDCKRQ1, TPD2E001QDBZRQ1 lacks dual-channel symmetry and fails to meet automotive USB/LVDS ESD requirements, while SMA6J5.0A-Q's excessive capacitance disrupts signal integrity - making TPD2E2U06QDCKRQ1 the only option satisfying simultaneous low-C, dual-channel, and AEC-Q101 demands.

FAQ
What is the primary function of the TPD2E2U06QDCKRQ1 in automotive electronics?
The TPD2E2U06QDCKRQ1 functions as a dual-channel transient voltage suppressor (TVS) diode array that provides electrostatic discharge (ESD) protection for high-speed signal lines. It diverts ESD energy to ground while maintaining low capacitance (1.5 pF) to preserve signal integrity on interfaces such as USB 2.0 and LVDS in automotive head units and telematics modules. Its AEC-Q101 qualification confirms suitability for under-hood and cabin-mounted applications.
Does the TPD2E2U06QDCKRQ1 require external power or biasing to operate?
No, the TPD2E2U06QDCKRQ1 is a fully passive device with no power supply pins or control inputs. It operates solely through its internal bidirectional diode structure, triggering automatically when voltage exceeds the 6.5-V minimum breakdown threshold. This eliminates design complexity and ensures fail-safe protection even during system power-down states - a critical feature for automotive safety-critical subsystems using the TPD2E2U06QDCKRQ1.
How does the SC70 (DCK) package of the TPD2E2U06QDCKRQ1 impact PCB layout?
The SC70 (DCK) package of the TPD2E2U06QDCKRQ1 measures 2.00 mm × 1.25 mm with a 0.65-mm pitch, enabling compact placement directly adjacent to connectors. Its flow-through pinout (IO1–IO2–GND) supports straight-line routing without vias or stubs, minimizing inductance and preserving high-frequency performance. Layout guidelines mandate short traces (<5 mm) from connector to TPD2E2U06QDCKRQ1 pins and direct connection of Pin 3 (GND) to a low-impedance ground plane to ensure optimal ESD current dissipation.
Can the TPD2E2U06QDCKRQ1 be used for both USB 2.0 and I²C interfaces?
Yes, the TPD2E2U06QDCKRQ1 is explicitly validated for both USB 2.0 and I²C applications. Its 1.5-pF capacitance supports USB 2.0's 480-Mbps data rate without signal degradation, while its 10-nA maximum leakage current prevents bus contention or false ACK/NACK generation on 3.3-V I²C lines. The device's symmetric dual-channel architecture allows flexible assignment of IO1/IO2 to SDA/SCL or D+/D−, and its –40°C to +125°C operating range ensures reliability across all automotive cabin and engine-bay I²C sensor networks using the TPD2E2U06QDCKRQ1.
What distinguishes the TPD2E2U06QDCKRQ1 from non-automotive ESD protectors like TPD2E2U06?
The TPD2E2U06QDCKRQ1 differs from the commercial-grade TPD2E2U06 through AEC-Q101 qualification, extended temperature range (–40°C to +125°C vs. –40°C to +85°C), enhanced ESD test reporting (including ISO 10605 compliance), and automotive-specific traceability and lot-control documentation. While both share identical electrical specs and SC70 packaging, only the TPD2E2U06QDCKRQ1 undergoes accelerated lifetime testing and failure analysis per automotive standards - making it mandatory for Tier 1 suppliers and OEM designs requiring functional safety alignment.
