Product details
Overview
TPD2EUSB30DRTR from Texas Instruments is a 2-channel unidirectional TVS diode array for ESD protection of USB 3.0 SuperSpeed differential data lines (D+, D−), featuring 0.7 pF typical IO-to-GND capacitance, 8 kV IEC 61000-4-2 contact ESD rating, and 5 A (8/20 µs) IEC 61000-4-5 surge current capability. It operates over −40°C to +85°C and supports 5 Gbps data rates in notebook and portable computing interfaces.
For engineers reviewing the TPD2EUSB30DRTR datasheet, TPD2EUSB30DRTR pinout, TPD2EUSB30DRTR application, or TPD2EUSB30DRTR equivalent, this device delivers low-clamp-voltage transient suppression with minimal signal integrity impact-critical for high-speed USB 3.0 layout integrity, eye diagram preservation, and system-level ESD robustness validation.
Technical Context
The TPD2EUSB30DRTR implements a dual-channel, flow-through SOT-9X3 (DRT) package topology with dedicated D+, D−, and GND terminals. Its internal structure uses matched low-capacitance clamping diodes referenced to ground, enabling bidirectional ESD event handling without DC bias requirements.
It functions passively: during transients exceeding ±4.5 V (breakdown) or below −0.6 V (forward conduction), it shunts energy to GND via low-dynamic-resistance (0.6 Ω typ) paths. Clamping voltage remains ≤8 V at 1 A, preserving downstream PHYs while maintaining <2 ps jitter penalty on 5 Gbps differential signals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC 61000-4-2) | ±8 kV contact discharge - meets Level 4, ensuring robustness against human-hand ESD events at connector interface |
| Surge Rating (IEC 61000-4-5) | 5 A (8/20 µs) per line - sustains high-energy surges without degradation, supporting industrial-grade USB port reliability |
| Capacitance (IO-to-GND) | 0.7 pF typical - minimizes signal loading to preserve 5 Gbps eye opening and insertion loss (<−3 dB up to 7.4 GHz) |
| Clamp Voltage (VCLAMP) | ≤8 V at 1 A - limits stress on connected USB 3.0 PHY, preventing latch-up or damage during ESD transients |
| Dynamic Resistance (RDYN) | 0.6 Ω typical - ensures fast, low-impedance path to ground, reducing voltage overshoot during nanosecond-scale ESD pulses |
| Breakdown Voltage (VBR) | 7 V minimum at 1 mA - provides margin above 5.5 V max operating voltage, avoiding false triggering during normal operation |
| Operating Temperature | −40°C to +85°C - qualified for consumer and industrial portable electronics environments |
Pinout & Package
SOT-9X3 (DRT) package: 1.00 mm × 0.80 mm body, 0.55 mm max height, 3-pin flow-through configuration optimized for USB 3.0 differential trace routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2EUSB30ADRTR | Lower 4.5 V breakdown voltage; rated for 0–3.6 V operating range vs. TPD2EUSB30DRTR's 0–5.5 V | Better suited for 3.3 V USB PHYs; higher risk of false triggering on 5 V-tolerant interfaces | Select TPD2EUSB30ADRTR only when protecting strictly 3.3 V signaling domains; otherwise TPD2EUSB30DRTR offers wider voltage margin. |
| TPD4EUSB30DQAR | 4-channel USON-10 (2.5 mm × 1.0 mm) package; 0.8 pF capacitance; supports two differential pairs (e.g., USB 3.0 + SS RX/TX) | Targets dual-lane or multi-interface protection (e.g., USB 3.0 + DisplayPort Alt Mode); not pin-compatible | Choose TPD4EUSB30DQAR when protecting multiple high-speed lanes on shared connectors; TPD2EUSB30DRTR remains optimal for single-pair cost-sensitive layouts. |
Compared with TPD2EUSB30ADRTR, TPD2EUSB30DRTR provides higher voltage tolerance and avoids premature clamping in mixed-supply systems; versus TPD4EUSB30DQAR, it offers lower capacitance and smaller footprint for dedicated USB 3.0 single-pair protection-making it the preferred choice for compact, 5 V–compatible SuperSpeed endpoints.

FAQ
What is the maximum data rate supported by the TPD2EUSB30DRTR?
The TPD2EUSB30DRTR supports USB 3.0 SuperSpeed data rates up to 5 Gbps. Its 0.7 pF typical IO-to-GND capacitance and measured −3 dB bandwidth of 7.4 GHz ensure minimal signal degradation, with validated eye diagram testing showing only ~2 ps jitter penalty in 5 Gbps operation-confirming full compatibility with USB 3.0 physical layer requirements.
Does the TPD2EUSB30DRTR require a power supply or bias voltage?
No, the TPD2EUSB30DRTR is a passive TVS diode array and requires no external power or bias. It operates solely through its internal clamping diodes, activating only during overvoltage transients (e.g., ESD or surge). The device is rated for 0–5.5 V continuous operation on D+/D− pins, making it compatible with standard USB 3.0 signaling without additional circuitry.
What is the recommended PCB layout practice for the TPD2EUSB30DRTR?
Place the TPD2EUSB30DRTR as close as possible to the USB 3.0 connector, using flow-through routing to maintain differential pair continuity. Connect the GND pin directly to the PCB ground plane via multiple large vias, avoid sharp trace corners, and keep unprotected traces away from protected D+/D− lines to prevent EMI coupling during ESD events-per TI's validated layout guidelines for IEC 61000-4-2 compliance.
How does the TPD2EUSB30DRTR differ from the TPD2EUSB30ADRTR?
The TPD2EUSB30DRTR has a 7 V minimum breakdown voltage and 0–5.5 V operating range, while the TPD2EUSB30ADRTR features a 4.5 V breakdown and 0–3.6 V range. This makes TPD2EUSB30DRTR safer for 5 V-tolerant USB PHYs, whereas TPD2EUSB30ADRTR is optimized for strict 3.3 V domains-using the wrong variant risks false triggering or insufficient protection margin.
Is the TPD2EUSB30DRTR compliant with international ESD and surge standards?
Yes, the TPD2EUSB30DRTR is fully compliant with IEC 61000-4-2 Level 4 (±8 kV contact, ±8 kV air-gap) for ESD immunity and IEC 61000-4-5 (5 A, 8/20 µs) for surge immunity. These ratings are verified per TI's production test protocols and documented in the SLVSAC2G datasheet revision June 2021, enabling system-level certification without additional external components.
