Product details
Overview
TPD1E10B06DPYT from Texas Instruments is a single-channel bidirectional ESD protection diode in X1SON (DPY) package, designed for low-voltage I/O lines with ±30kV IEC 61000-4-2 contact/air-gap ESD immunity, 12pF typical I/O capacitance, and 0.4Ω typical dynamic resistance. It protects audio interfaces, USB ID/ID pins, and GPIO in space-constrained portable electronics.
For engineers reviewing the TPD1E10B06DPYT datasheet, TPD1E10B06DPYT pinout, TPD1E10B06DPYT application, or TPD1E10B06DPYT equivalent, key selection criteria include clamping voltage at 1A (≤10V), reverse standoff voltage (5.5V), industrial temperature range (–40°C to 125°C), and compatibility with 400Mbps data rates due to low capacitance.
Technical Context
The TPD1E10B06DPYT implements a back-to-back TVS diode structure enabling bidirectional clamping for AC-coupled or floating signal lines like audio paths and USB ID pins. Its low 12pF capacitance ensures minimal signal distortion up to 400Mbps, while the 0.4Ω dynamic resistance maintains tight clamping during ±30kV ESD transients.
It operates passively with no power supply required, activating only when voltage exceeds ±6V breakdown threshold. The device sustains 6A IEC 61000-4-5 surge current (8/20µs) and exhibits ≤100nA leakage below 5.5V reverse standoff, supporting battery-sensitive wearables and portable devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Protection Level | ±30kV contact & air-gap per IEC 61000-4-2 - meets Level 4 system-level ESD immunity without external circuitry |
| Clamp Voltage (IPP = 1A) | 10V max - limits stress on downstream ICs during ESD events |
| I/O Capacitance | 12pF typical at 1MHz - supports 400Mbps data rates with negligible insertion loss in audio/USB lines |
| Dynamic Resistance | 0.4Ω typical - minimizes voltage overshoot during fast transients |
| Reverse Standoff Voltage | 5.5V - ensures no conduction during normal operation of 3.3V/5V I/O |
| Breakdown Voltage | ±6V min - defines symmetric triggering threshold for bidirectional signal protection |
| Leakage Current | 100nA max at 5V - preserves battery life in always-on wearable sensors and buttons |
Pinout & Package
X1SON (DPY) 2-pin no-lead package: 1.0mm × 0.6mm × 0.45mm body, 0.45mm max height, exposed thermal pad, industry-standard footprint compatible with automated SMT assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | ESD-Protected I/O | Bidirectional signal terminal; connects to protected line (e.g., microphone input or USB ID pin); must be routed close to connector |
| 2 | Ground Reference | Low-inductance return path to system ground; requires short, wide trace to minimize loop inductance during ESD discharge |
Key Features
| Feature | Design Value |

| Bidirectional TVS Structure | Enables protection of AC-coupled or floating signals (e.g., stereo audio, USB ID) without polarity constraints |
| Ultra-Low Capacitance | 12pF supports high-fidelity audio transmission and high-speed digital interfaces without bandwidth limiting |
| Low Dynamic Resistance | 0.4Ω ensures clamp voltage stays near specification limit under 1A–5A surges, reducing IC stress |
| Small 0402-Compatible Footprint | 1.0mm × 0.6mm area saves PCB space in wearables, earbuds, and compact IoT endpoints |
| Industrial Temperature Range | –40°C to 125°C operation enables use in automotive infotainment, smart home hubs, and outdoor appliances |
Applications
| Audio Line Protection | USB Interface Protection |
|---|---|
Use Scenario: Protecting microphone, earphone, and speakerphone lines in smartphones and wireless earbuds from user-hand ESD. IC Role / Device Role / Timing Role: Bidirectional ESD clamp placed between connector and codec amplifier, shunting transients to ground before reaching sensitive analog front-end.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z3.3T5G | 3.3V VRWM, 15pF capacitance, ±22kV IEC contact rating | Lower clamping voltage but reduced ESD margin; suited for 3.3V-only systems with tighter voltage headroom | Select when protecting 3.3V logic with lower VBR tolerance; not suitable for 5V-tolerant or USB VBUS lines |
| CM1213A-03SR | 3.3V VRWM, 10pF capacitance, ±15kV IEC contact rating, SOD-523 package | Lower ESD rating and narrower operating temperature (–40°C to 85°C); optimized for cost-sensitive consumer electronics | Choose for budget-driven designs where Level 3 ESD (±15kV) suffices and extended temperature range is unnecessary |
Compared with ESD5Z3.3T5G and CM1213A-03SR, the TPD1E10B06DPYT delivers superior ±30kV system-level ESD immunity, wider 5.5V standoff, and full industrial temperature support-making it optimal for premium portable devices, USB peripherals, and ruggedized I/O interfaces where reliability is critical.

FAQ
What is the maximum clamping voltage of the TPD1E10B06DPYT during an ESD event?
The TPD1E10B06DPYT has a maximum clamping voltage of 10V at 1A (8/20µs surge), and 14V at 5A. This value is measured with pin 1 struck and pin 2 grounded, and reflects the voltage presented to the protected IC during transient suppression. The low 0.4Ω dynamic resistance ensures predictable, repeatable clamping behavior critical for safeguarding sensitive audio codecs and USB transceivers in the TPD1E10B06DPYT application space.
Does the TPD1E10B06DPYT require a power supply or biasing circuit?
No, the TPD1E10B06DPYT is a passive bidirectional TVS diode and requires no external power, bias, or control signals. It remains in high-impedance state below ±6V breakdown and activates only during overvoltage events. This makes the TPD1E10B06DPYT ideal for always-on, low-power applications such as wearable sensor nodes and battery-operated remote controls where quiescent current must be minimized.
Can the TPD1E10B06DPYT protect USB 2.0 data lines (D+ and D–)?
No-the TPD1E10B06DPYT is a single-channel device intended for individual signal lines like USB ID, VBUS, or auxiliary pins-not differential pairs. For USB 2.0 D+/D– protection, a dedicated dual-channel or array device (e.g., TPD2EUSB30) with matched capacitance and skew is required. The TPD1E10B06DPYT is appropriate for USB ID pin protection or VBUS overvoltage clamping, but not high-speed data pair routing.
What is the thermal resistance (RθJA) of the TPD1E10B06DPYT in its DPY package?
The junction-to-ambient thermal resistance (RθJA) of the TPD1E10B06DPYT in the X1SON (DPY) package is 615.5°C/W under standard JEDEC test conditions. This value assumes a 2-layer board with 1 in² copper pour. Effective heat dissipation relies on proper PCB layout-including thermal vias under the exposed pad-especially in high-density layouts where multiple TPD1E10B06DPYT units may operate simultaneously during surge events.
Is the TPD1E10B06DPYT RoHS compliant and lead-free?
Yes, the TPD1E10B06DPYT is RoHS compliant and features a lead-free NiPdAu (NIPDAU) termination finish. It meets JEDEC J-STD-020 moisture sensitivity level (MSL) 1 with unlimited floor life at ≤30°C/60% RH, and is rated for peak reflow temperatures up to 260°C. These attributes ensure compatibility with modern lead-free SMT assembly processes and environmental compliance requirements for global electronics manufacturing, including those governing the TPD1E10B06DPYT supply chain.
