Product details
Overview
TPD1E10B06QDPYRQ1 from Texas Instruments is an AEC-Q101-qualified, bidirectional TVS diode for automotive ESD protection of single 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 - deployed on audio lines, GPIOs, and memory interfaces in head units and telematics modules.
For engineers reviewing the TPD1E10B06QDPYRQ1 datasheet, TPD1E10B06QDPYRQ1 pinout, TPD1E10B06QDPYRQ1 application, or TPD1E10B06QDPYRQ1 equivalent, key selection criteria include its ±5.5-V operating voltage range, -40°C to +125°C automotive temperature rating, X1SON (DPY) 0.6 mm × 1.0 mm package, and ISO 10605-compliant ±8-kV/±15-kV (DPY) discharge performance.
Technical Context
The TPD1E10B06QDPYRQ1 implements a back-to-back TVS diode structure enabling true bidirectional clamping for AC-coupled or floating signal paths such as stereo audio inputs and pushbutton interfaces. Its low 0.32–0.38 Ω dynamic resistance ensures minimal voltage overshoot during transient events, while the 12-pF capacitance supports signal integrity up to 400 Mbps without distortion.
This device operates passively below its 5.5-V reverse stand-off voltage (VRWM), exhibiting only 100 nA max leakage at 5 V bias, then triggers above ±6-V DC breakdown to divert ESD energy to ground. It meets IEC 61000-4-5 (6 A, 8/20 µs) and ISO 10605 (330 pF/330 Ω) surge requirements specifically for the DPY (X1SON) package variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC 61000-4-2) | ±30-kV contact & air-gap - exceeds Level 4, protects against worst-case human-body discharges in dry environments |
| I/O Capacitance | 12 pF (typical at 2.5 V, 1 MHz) - enables clean transmission of audio (20 Hz–20 kHz) and high-speed GPIO signals |
| Clamping Voltage | 10 V (typical at IPP = 1 A, 8/20 µs) - limits stress on downstream ICs like Class AB audio amplifiers |
| Dynamic Resistance | 0.38 Ω (Pin 2 → Pin 1) - minimizes voltage drop across diode during conduction, improving clamping precision |
| DC Breakdown Voltage | ≥6 V (min, 1 mA test) - ensures reliable triggering above system operating voltage (±5.5 V) |
| Leakage Current | ≤100 nA (max at 5 V bias) - prevents power drain in battery-sensitive automotive modules |
| Operating Temperature | –40°C to +125°C - qualified for under-hood and infotainment applications per AEC-Q101 |
Pinout & Package
TPD1E10B06QDPYRQ1 uses the X1SON (DPY) 2-pin package (0.6 mm × 1.0 mm, 0.4 mm height), optimized for space-constrained automotive PCBs and compatible with automated optical inspection (AOI). The device has no polarity marking; both pins are functionally identical I/O terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | I/O | Bidirectional ESD-protected signal terminal - connects to protected line (e.g., L Audio IN); symmetric with Pin 2 |
| Pin 2 | I/O | Bidirectional ESD-protected signal terminal - connects to system ground or complementary signal path; identical electrical behavior to Pin 1 |
Key Features

IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed between connector and Class AB amplifier input, triggered only during ±30-kV ESD strikes. Use Value: 12-pF capacitance avoids attenuation of 20 Hz–20 kHz audio band; 10-V clamping prevents amplifier latch-up or distortion. | Use Scenario: Shielding microcontroller GPIOs connected to external pushbuttons in body control modules. IC Role / Device Role / Timing Role: Passive ESD shunt mounted directly at button PCB pads, conducting transient current to chassis ground before MCU pin damage. Use Value: 0.38-Ω RDYN ensures fast response and low clamping voltage; 100-nA leakage preserves sleep-mode current budget. |
| Memory Interface Protection | Telematics RF Front-End Protection |
Use Scenario: Safeguarding SPI/I²C lines between infotainment SoC and external flash memory in premium audio systems. IC Role / Device Role / Timing Role: Low-capacitance TVS on bidirectional data/clock lines, maintaining timing margins and signal rise/fall times. Use Value: 12-pF loading adds <1% delay to 10-MHz SPI edges; ±6-V breakdown avoids false triggering during normal 3.3-V operation. | Use Scenario: ESD hardening of antenna switch control lines in cellular/V2X telematics modules exposed to service port handling. IC Role / Device Role / Timing Role: Transient suppressor on low-voltage DC control signals routed near RF antennas and external connectors. Use Value: AEC-Q101 qualification guarantees reliability in thermally cycling environments; ±5.5-V operating range matches typical PMIC output rails. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD1E10B06DYARQ1 | SOD-523 (DYA) package (0.8 mm × 1.2 mm); ±25-kV ISO 10605 contact/air; higher RθJA (730.8°C/W) | Better suited for AOI-compatible assembly; slightly lower ESD margin on ISO 10605 vs. DPY's ±8/±15 kV | Select when leaded package is required for legacy reflow or optical inspection compatibility |
| ESD108B1W050024 | 12-pF, ±30-kV IEC, but rated only to +105°C; non-automotive grade; 0.5-pF lower capacitance | Limited to industrial or consumer infotainment subsystems; not AEC-Q101 qualified | Choose for cost-sensitive non-safety-critical designs where full automotive temp range is unnecessary |
Compared with TPD1E10B06DYARQ1 and ESD108B1W050024, the TPD1E10B06QDPYRQ1 uniquely combines X1SON miniaturization (0.6 mm × 1.0 mm), AEC-Q101 certification, and the highest ISO 10605 ratings (±8-kV contact) among its direct TI variants - making it optimal for next-gen compact automotive ECUs requiring maximum ESD margin in minimal board area.

FAQ
What is the package type and dimensions of the TPD1E10B06QDPYRQ1?
The TPD1E10B06QDPYRQ1 uses the X1SON (DPY) package, measuring 0.6 mm × 1.0 mm with a height of 0.4 mm. This 2-pin, leadless footprint is designed for high-density automotive PCB layouts and supports automated optical inspection. Its small size makes the TPD1E10B06QDPYRQ1 ideal for space-constrained applications such as camera modules and compact infotainment controllers.
Does the TPD1E10B06QDPYRQ1 support bidirectional signal protection?
Yes, the TPD1E10B06QDPYRQ1 implements a back-to-back TVS diode configuration, enabling symmetrical ±30-kV IEC 61000-4-2 ESD protection on both polarities. Its bidirectional clamping behavior - with 6-V minimum breakdown in either direction - makes the TPD1E10B06QDPYRQ1 especially suitable for AC-coupled audio lines, pushbutton interfaces, and other floating or reversible signal paths in automotive systems.
What is the maximum clamping voltage of the TPD1E10B06QDPYRQ1 during ESD events?
The TPD1E10B06QDPYRQ1 exhibits a typical clamping voltage of 10 V at 1-A transient current (8/20 µs waveform) when surge is applied from Pin 1 to Pin 2, and 8.5 V when applied from Pin 2 to Pin 1. These values ensure downstream components - such as audio amplifiers or microcontroller GPIOs - remain within safe operating limits during ±30-kV ESD strikes, confirming the TPD1E10B06QDPYRQ1's effectiveness in system-level protection schemes.
Is the TPD1E10B06QDPYRQ1 qualified for automotive applications?
Yes, the TPD1E10B06QDPYRQ1 is explicitly AEC-Q101 qualified and rated for operation from –40°C to +125°C. It meets automotive-grade reliability requirements including HBM ±2.5 kV and CDM ±1 kV testing. This qualification, combined with ISO 10605 and IEC 61000-4-5 compliance, confirms the TPD1E10B06QDPYRQ1's suitability for safety-critical automotive subsystems such as body control modules, gateways, and telematics units.
How does the 12-pF capacitance of the TPD1E10B06QDPYRQ1 affect signal integrity?
The 12-pF typical I/O capacitance of the TPD1E10B06QDPYRQ1 introduces negligible loading on audio (20 Hz–20 kHz), GPIO, and memory interface signals - supporting data rates up to 400 Mbps without measurable distortion or edge degradation. At 2.5 V bias and 1 MHz, this value ensures the TPD1E10B06QDPYRQ1 maintains signal fidelity while still providing robust ESD suppression, making it appropriate for high-fidelity automotive audio and responsive touch-control applications.
