Product details
Overview
TPD1E10B06DYARQ1 from Texas Instruments is an AEC-Q101-qualified, bidirectional TVS diode for automotive ESD protection of single-ended I/O lines. It delivers ±30-kV IEC 61000-4-2 contact/air-gap ESD immunity, 12-pF I/O capacitance, 0.38-Ω dynamic resistance (Pin 2→1), and 10-V clamping voltage at 1-A surge - enabling robust protection of audio lines, pushbuttons, and GPIO in head units and telematics modules.
For engineers reviewing the TPD1E10B06DYARQ1 datasheet, TPD1E10B06DYARQ1 pinout, TPD1E10B06DYARQ1 application, or TPD1E10B06DYARQ1 equivalent, key selection criteria include its SOD-523 (DYA) package compatibility with AOI, ±5.5-V operating voltage range, -40°C to +125°C automotive temperature rating, and verified ISO 10605 ±25-kV contact/air-gap performance in the DYA variant.
Technical Context
The TPD1E10B06DYARQ1 implements a back-to-back TVS diode structure for true bidirectional clamping, triggering above ±6-V DC breakdown and clamping transients to ≤14 V at 5-A (8/20 µs). Its low 12-pF capacitance supports signal integrity up to 400 Mbps, while ultra-low 100-nA leakage ensures minimal power impact on battery-sensitive interfaces.
Designed specifically for the SOD-523 (DYA) package, it achieves 6-A IEC 61000-4-5 surge capability and meets ISO 10605 requirements with ±25-kV contact/air-gap ratings - distinct from the DPY (X1SON) variant's ±8-kV/±15-kV values. Thermal resistance is 730.8°C/W (RθJA), optimized for surface-mount reliability in compact automotive PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC 61000-4-2) | ±30-kV contact & air-gap - exceeds Level 4, protecting against worst-case human-body ESD events in vehicle cabins. |
| I/O Capacitance | 12 pF (typical at 2.5 V, 1 MHz) - preserves audio fidelity and supports >400-Mbps data rates without signal distortion. |
| Clamping Voltage | 10 V (typical at 1-A, 8/20 µs) - limits transient voltage seen by downstream ICs to safe levels during ESD strikes. |
| Dynamic Resistance | 0.38 Ω (Pin 2→1) - minimizes voltage overshoot during fast transients, enhancing system-level robustness. |
| DC Breakdown Voltage | ±6 V (min) - ensures reliable triggering above ±5.5-V operating range while avoiding false conduction during normal signal swings. |
| Leakage Current | ≤100 nA (max at 5 V) - negligible power loss in always-on automotive interfaces like wake-up GPIO or sensor lines. |
| Operating Temperature | -40°C to +125°C - certified for under-hood and infotainment module deployment per AEC-Q101. |
Pinout & Package
SOD-523 (DYA) package: 0.80 mm × 1.2 mm × 0.65 mm body, industry-standard leaded footprint compatible with automatic optical inspection (AOI) and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I/O | Bidirectional protected signal line - connects directly to interface (e.g., audio IN, GPIO) requiring ESD suppression. |
| 2 | I/O | Common return path - must be connected to system ground with low-inductance trace to ensure effective clamping. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use across -40°C to +125°C, including HBM ±2500 V and CDM ±1000 V stress testing. |
| ISO 10605 compliance (DYA) | ±25-kV contact & air-gap (330 pF, 330 Ω) - meets stringent automotive ESD requirements for external connectors. |
| Low clamping voltage | 10 V at 1-A surge - reduces stress on sensitive analog front-ends like Class AB audio amplifiers. |
| Space-constrained packaging | SOD-523 (DYA) footprint - enables placement within 2 mm of connectors for optimal ESD path inlay-out. |
| Bidirectional TVS architecture | Back-to-back diode pair - protects AC-coupled and bidirectional signals (e.g., I²C, USB D+/D-) without polarity concerns. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD1E10B06QDPYRQ1 | X1SON (DPY) package (0.6 mm × 1.0 mm); lower RθJA (615.5°C/W); ±8-kV/±15-kV ISO 10605 rating. | Preferred for space-limited layouts needing thermal efficiency; unsuitable where AOI or higher ISO 10605 margin is required. | Select when board area is critical and ISO 10605 demands are ≤±15-kV air-gap. |
| ESD9B5.0ST5G | SOD-523 package; ±12-V breakdown; 15-pF capacitance; ±22-kV IEC 61000-4-2; not AEC-Q101 qualified. | Limited to industrial or non-safety-critical automotive subsystems; lacks automotive qualification and ISO 10605 validation. | Use only in cost-sensitive, non-automotive designs where AEC-Q101 and ISO 10605 are not mandated. |
Compared with TPD1E10B06QDPYRQ1 and ESD9B5.0ST5G, the TPD1E10B06DYARQ1 uniquely combines SOD-523 manufacturability (AOI support), AEC-Q101 certification, and the highest ISO 10605 rating (±25-kV) among its direct variants - making it the only choice for production-grade automotive audio and gateway interfaces requiring full compliance.

FAQ
What is the package type of TPD1E10B06DYARQ1?
TPD1E10B06DYARQ1 uses the SOD-523 (DYA) package - a 2-pin, leaded surface-mount device measuring 0.80 mm × 1.2 mm × 0.65 mm. This package supports automatic optical inspection (AOI) and is distinct from the X1SON (DPY) variant used in TPD1E10B06QDPYRQ1. The DYA variant is explicitly validated for ±25-kV ISO 10605 contact/air-gap ESD performance.
Does TPD1E10B06DYARQ1 meet AEC-Q101 requirements?
Yes, TPD1E10B06DYARQ1 is fully AEC-Q101 qualified for automotive applications. It passes Human Body Model (HBM) ±2500 V and Charged Device Model (CDM) ±1000 V testing per AEC-Q101-001 and AEC-Q101-005 standards, and operates across the full automotive temperature range of -40°C to +125°C. This qualification is documented in TI's official datasheet revision history and orderable addendum.
What is the maximum clamping voltage of TPD1E10B06DYARQ1 during ESD events?
The TPD1E10B06DYARQ1 clamps to 10 V (typical) at 1-A surge current (8/20 µs waveform) and 14 V (typical) at 5-A. These values are measured with surge applied to Pin 1 (grounded Pin 2) or Pin 2 (grounded Pin 1), confirming symmetrical bidirectional clamping behavior essential for protecting AC-coupled signals like audio lines and I²C buses.
Can TPD1E10B06DYARQ1 protect high-speed interfaces like USB or MIPI?
TPD1E10B06DYARQ1 is not recommended for USB 2.0 (480 Mbps) or MIPI D-PHY (≥800 Mbps) due to its 12-pF capacitance, which may degrade signal integrity at those data rates. It is validated for interfaces up to 400 Mbps - suitable for audio, SPI, I²C, and GPIO, but not high-speed serial protocols requiring sub-3-pF capacitance. For USB, consider TI's TPD4E001 or similar low-capacitance alternatives.
How does the ISO 10605 rating of TPD1E10B06DYARQ1 compare to the DPY variant?
TPD1E10B06DYARQ1 (SOD-523/DYA) achieves ±25-kV contact and ±25-kV air-gap per ISO 10605 (330 pF, 330 Ω), whereas the DPY (X1SON) variant is rated at ±8-kV contact and ±15-kV air-gap. This difference is explicitly documented in Section 6.3 of the datasheet and reflects package-dependent ESD path characteristics - making TPD1E10B06DYARQ1 the preferred choice for automotive exterior interfaces demanding highest ISO immunity.
