Product details
Overview
TPD1E10B09DPYT from Texas Instruments is a single-channel bidirectional ESD protection TVS diode in X1SON (DPY) 2-pin 0402 package, providing ±20 kV IEC 61000-4-2 Level 4 contact/air-gap ESD suppression, 10 pF I/O capacitance, and 0.5 Ω dynamic resistance for high-speed audio and GPIO lines in space-constrained wearables and tablets.
For engineers reviewing the TPD1E10B09DPYT datasheet, TPD1E10B09DPYT pinout, TPD1E10B09DPYT application, or TPD1E10B09DPYT equivalent, key selection criteria include clamping voltage at 1 A (≤13 V), reverse standoff voltage (±9 V), industrial temperature range (–40°C to 125°C), ultra-low leakage (≤100 nA), and compatibility with 500 Mbps data rates.
Technical Context
The TPD1E10B09DPYT implements a back-to-back TVS diode configuration enabling bipolar signal support across ±9 V operating range, with bidirectional breakdown voltage ≥±9.5 V and clamping voltage ≤13 V at 1 A transient current. Its 10 pF capacitance is measured at 1 MHz and 2.5 V bias, supporting distortion-free audio (20 Hz–20 kHz) and high-speed interfaces up to 500 Mbps.
As a passive clamp, it remains in high-impedance state below VRWM (±9 V), activates above VBR (±9.5 V), and dissipates surge energy via low RDYN (0.5 Ω typ), limiting voltage stress on protected ICs during ±20 kV ESD events and 4.5 A IEC 61000-4-5 surges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC 61000-4-2) | ±20 kV contact & air-gap - meets Level 4 system-level immunity for consumer and industrial end equipment |
| Clamp Voltage (IPP = 1 A) | ≤13 V - limits voltage stress on downstream audio amplifier or MCU GPIO during ESD strike |
| I/O Capacitance | 10 pF @ 1 MHz, 2.5 V - enables clean 500 Mbps signal integrity without high-frequency attenuation |
| Dynamic Resistance | 0.5 Ω typical - ensures low voltage drop under transient current, improving clamping efficiency |
| Reverse Standoff Voltage | ±9 V - supports bidirectional signals up to ±8 V (e.g., audio lines, USB ID/VD pins) without leakage activation |
| Leakage Current | ≤100 nA @ 5 V - minimizes power loss in battery-powered wearables and remote controllers |
| Surge Rating (IEC 61000-4-5) | 4.5 A (8/20 µs) - provides robust protection against lightning-induced surges on exposed connectors |
Pinout & Package
X1SON (DPY) 2-pin 0402 package: 1.0 mm × 0.6 mm × 0.45 mm max height, industry-standard footprint with exposed thermal pad (not electrically connected), compatible with standard SMT reflow profiles (MSL Level-1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I/O | Bidirectional signal line terminal - connects directly to protected trace (e.g., microphone input, button line) |
| 2 | GND | Low-inductance ground return path - requires short, wide trace to minimize impedance during ESD discharge |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional TVS architecture | Enables protection of AC-coupled or dual-polarity signals (e.g., stereo audio, USB ID pin) without polarity constraints |
| 10 pF capacitance at 1 MHz | Preserves signal fidelity for audio (20 Hz–20 kHz) and high-speed digital lines up to 500 Mbps |
| 0.5 Ω dynamic resistance | Reduces clamping voltage overshoot during fast transients, enhancing protection margin for sensitive ICs |
| Industrial temperature range | Operates reliably from –40°C to 125°C - suitable for automotive cabin modules and outdoor IoT devices |
| Space-saving 0402 footprint | Minimizes PCB area in ultra-thin tablets, smartwatches, and compact EPOS terminals |
Applications
| Audio Line Protection | GPIO & Button Protection |
|---|---|
Use Scenario: Protecting microphone, earphone, and speaker phone lines in tablets and wearables from user-hand ESD. IC Role / Device Role / Timing Role: Bidirectional ESD clamp placed between connector and audio codec, shunting transients to ground before reaching analog front-end. Use Value: 10 pF capacitance avoids audio band attenuation; ±20 kV rating exceeds IEC 61000-4-2 Level 4 requirements for handheld devices. |
Use Scenario: Shielding mechanical push-buttons and capacitive touch keys in remote controllers and set-top boxes. IC Role / Device Role / Timing Role: Low-leakage (≤100 nA) TVS diode placed inline with microcontroller GPIO, preventing latch-up during repeated button actuation. Use Value: 0.5 Ω RDYN ensures rapid clamping (<1 ns response), suppressing ESD-induced resets without affecting debounce timing. |
| USB Interface Protection | EPOS Terminal I/O Protection |
Use Scenario: Safeguarding VBUS and ID pins of micro-USB ports in portable electronics against hot-plug and cable discharge events. IC Role / Device Role / Timing Role: Back-to-back diode configuration handles both positive and negative transients on bidirectional ID line and DC-biased VBUS. Use Value: ±9 V VRWM aligns with USB 2.0 signaling levels; 13 V clamping at 1 A prevents overvoltage damage to USB controller PHY. |
Use Scenario: Securing general-purpose I/O ports (RS-232, keypad scan lines) in electronic point-of-sale terminals exposed to retail environments. IC Role / Device Role / Timing Role: Primary ESD barrier at board edge, routing transients from customer-facing connectors directly to chassis ground. Use Value: 4.5 A IEC 61000-4-5 surge rating withstands induced surges from nearby AC mains switching in commercial settings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5V3U2U-2/TR | Higher capacitance (15 pF), lower clamping voltage (11 V @ 1 A), same 0402 X1SON package | Better suited for sub-200 Mbps interfaces where lower clamping outweighs capacitance penalty | Select when protecting low-speed GPIO or legacy USB where <11 V clamping is critical and 15 pF is acceptable |
| TPD1E05U06DPYT | Lower capacitance (5.5 pF), reduced ESD rating (±12 kV), same 2-pin X1SON footprint | Optimized for >1 Gbps high-speed lines (e.g., MIPI D-PHY) but insufficient for Level 4 system ESD | Choose only for bandwidth-critical applications requiring <6 pF; not recommended for tablet/audio ESD compliance |
Compared with ESD5V3U2U-2/TR and TPD1E05U06DPYT, the TPD1E10B09DPYT delivers the optimal balance of Level 4 ESD immunity, 10 pF capacitance for 500 Mbps support, and industrial temperature operation - making it the preferred choice for audio, USB, and general-purpose I/O protection in consumer and industrial portable devices.

FAQ
What is the maximum clamping voltage of the TPD1E10B09DPYT during an ESD event?
The TPD1E10B09DPYT has a maximum clamping voltage of 13 V when subjected to a 1 A transient current (8/20 µs waveform), and 17 V at 5 A. This low clamping level protects downstream components such as audio codecs and microcontrollers by limiting voltage stress during ±20 kV IEC 61000-4-2 ESD strikes. The clamping performance is guaranteed across the full industrial temperature range (–40°C to 125°C).
Can the TPD1E10B09DPYT be used to protect USB 2.0 data lines?
No - the TPD1E10B09DPYT is not recommended for USB 2.0 D+/D– differential pairs due to its 10 pF capacitance, which may degrade signal integrity at 480 Mbps. It is qualified for USB VBUS and ID pins (single-ended, DC-biased), audio lines, GPIO, and buttons. For USB 2.0 data lines, TI recommends lower-capacitance alternatives like TPD1E05U06DPYT (5.5 pF) or dedicated USB ESD arrays.
What is the package type and dimensions of the TPD1E10B09DPYT?
The TPD1E10B09DPYT uses the X1SON (DPY) 2-pin package - a 0402-sized no-lead outline measuring 1.0 mm × 0.6 mm × 0.45 mm max height. It features a bottom-exposed thermal pad (non-functional) and complies with JEDEC MSL Level-1 moisture sensitivity. The pin 1 index is located in Quadrant Q1 per tape-and-reel packaging specifications.
Does the TPD1E10B09DPYT require external power or biasing?
No - the TPD1E10B09DPYT is a passive bidirectional TVS diode and requires no external power, biasing, or control signals. It operates solely based on voltage threshold behavior: remaining high-impedance below ±9 V reverse standoff voltage and clamping transients above ±9.5 V breakdown voltage. Its 100 nA max leakage at 5 V ensures negligible impact on battery life in portable systems.
Is the TPD1E10B09DPYT suitable for automotive applications?
The TPD1E10B09DPYT is rated for industrial temperature (–40°C to 125°C) but is not AEC-Q200 qualified. For automotive use, TI offers the pin-compatible TPD1E10B09-Q1, which undergoes full automotive qualification including extended temperature testing, vibration, and humidity cycling. The TPD1E10B09DPYT may be used in non-safety-critical infotainment accessories, but not in ADAS or powertrain systems.
