Product details
Overview
TPD2E2U06DRLR from Texas Instruments is a dual-channel, low-capacitance TVS diode ESD protection device in a 5-pin SOT-5X3 (DRL) package, rated for ±25 kV contact / ±30 kV air-gap IEC 61000-4-2 ESD protection, 1.5 pF typical line capacitance, and 6.5 V minimum DC breakdown voltage - designed specifically for USB 2.0 data-line protection at up to 480 Mbps.
For engineers reviewing the TPD2E2U06DRLR datasheet, TPD2E2U06DRLR pinout, TPD2E2U06DRLR application, or TPD2E2U06DRLR equivalent, this page delivers verified electrical parameters, validated DRL-package pin mapping, USB 2.0 interface-specific implementation guidance, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The TPD2E2U06DRLR implements a symmetric dual-diode architecture per channel - each I/O pin (IO1, IO2) features bidirectional clamping to GND with matched dynamic resistance (0.5 Ω IO→GND, 0.25 Ω GND→IO) and low clamping voltage (9.7 V at 1 A TLP). It operates passively without bias, triggering only during overvoltage transients above 6.5 V breakdown.
Its 1.5 pF line-to-ground capacitance and 0.03 pF channel-to-channel cross-capacitance preserve signal integrity for high-speed interfaces including USB 2.0 (240 MHz fundamental), while its –40°C to +125°C operating range supports industrial and embedded host applications where thermal stability is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC 61000-4-2) | ±25 kV contact / ±30 kV air-gap - meets Level 4 immunity for direct human touch on USB connectors. |
| Line Capacitance (CL) | 1.5 pF (typ) at 1 MHz, 2.5 V - enables full-speed USB 2.0 (480 Mbps) without signal degradation. |
| DC Breakdown Voltage (VBR) | 6.5 V (min) at 1 mA - ensures robust protection margin above 5.5 V USB VBUS and 3.3 V logic rails. |
| ESD Clamping Voltage (VCLAMP) | 9.7 V (typ) at 1 A TLP - limits transient stress on downstream PHY ICs during fast ESD events. |
| Leakage Current (ILEAK) | 10 nA (max) at 2.5 V - prevents measurable loading of high-impedance I²C or LVDS receivers. |
| Peak Pulse Current (IPP) | 5.5 A (8/20 µs) - sustains surge energy from IEC 61000-4-5 Line-to-Ground surges without failure. |
| Operating Temperature | –40°C to +125°C - qualified for industrial-grade USB ports in set-top boxes, servers, and EPOS terminals. |
Pinout & Package
SOT-5X3 (DRL) package: 1.60 mm × 1.20 mm body, 0.6 mm max height, 5-pin layout with flow-through routing optimized for minimal trace stubs between USB connector and protected IC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IO1 | Dual-channel ESD protection input/output - connects directly to USB D+ or D− line near connector. |
| 2 | IO2 | Second independent ESD protection channel - used for complementary USB data line (D− or D+). |
| 3 | NC | No-connect terminal - internally unconnected; must be left floating, grounded, or tied to VCC per layout requirements. |
| 4 | GND | Common ground reference for both clamping diodes - requires low-inductance connection to system ground plane. |
| 5 | NC | No-connect terminal - identical function to Pin 3; no internal bond wire or circuit connection. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel low-capacitance ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | Single-channel, 0.65 pF capacitance, lower 5.5 V breakdown, SC70-3 package (3-pin) | Limited to one data line; insufficient for full USB 2.0 D+/D− protection without duplication | Select only when protecting isolated high-speed signals (e.g., MIPI D-PHY clock) where ultra-low capacitance outweighs dual-channel need |
| ESD5451N-2/TR | 0.8 pF capacitance, ±20 kV contact rating, SOT-563 package, higher 12 V clamping at 1 A | Lower ESD rating and higher clamping reduce safety margin for USB 2.0 PHYs with 10 V absolute max ratings | Acceptable for cost-sensitive consumer electronics where IEC 61000-4-2 Level 3 (±20 kV) suffices and board space permits SOT-563 footprint |
Compared with TPD2E2U06DRLR, TPD2E001DRYR requires two devices for USB 2.0 and offers lower capacitance but reduced ESD margin, while ESD5451N-2/TR provides smaller footprint and lower cost but sacrifices 5 kV ESD headroom and clamping performance critical for industrial USB reliability.

FAQ
What is the maximum data rate supported by TPD2E2U06DRLR?
TPD2E2U06DRLR supports full-speed USB 2.0 operation at 480 Mbps. Its 1.5 pF typical line capacitance and <0.03 pF channel-to-channel coupling ensure minimal signal distortion, with measured insertion loss below –1 dB up to 500 MHz - sufficient for maintaining USB 2.0 eye diagram compliance under worst-case trace lengths.
Does TPD2E2U06DRLR require an external power supply or bias voltage?
No, TPD2E2U06DRLR is a passive TVS diode device and requires no external power or bias. It operates solely through avalanche breakdown of internal PN junctions during overvoltage events. The device draws only 10 nA maximum leakage at 2.5 V, making it compatible with battery-powered USB peripherals and always-on debug interfaces.
Can TPD2E2U06DRLR be used for interfaces other than USB 2.0?
Yes, TPD2E2U06DRLR is validated for LVDS and I²C interfaces per TI documentation. Its 1.5 pF capacitance and bidirectional clamping suit differential pairs up to 650 Mbps (LVDS) and open-drain buses with 3.3 V or 5 V logic levels (I²C), provided operating voltage remains within the 0–5.5 V recommended range and ESD threat level matches IEC 61000-4-2 Level 4 requirements.
What is the correct PCB layout practice for TPD2E2U06DRLR?
Place TPD2E2U06DRLR within 2 mm of the USB connector, route D+ and D− traces straight through Pins 1 and 2 with no stubs, connect Pin 4 (GND) to a solid ground plane using ≥2 vias, and leave Pins 3 and 5 (NC) unconnected. Avoid routing unprotected signals near the protected traces to prevent EMI coupling during ESD events.
Is TPD2E2U06DRLR compliant with automotive standards?
TPD2E2U06DRLR is not AEC-Q200 qualified. For automotive applications, TI specifies the pin-compatible TPD2E2U06-Q1 variant, which undergoes additional temperature cycling, humidity testing, and zero-defect screening per AEC-Q100 Grade 2 (–40°C to +105°C) requirements. Use TPD2E2U06-Q1 in infotainment, telematics, or ADAS USB subsystems.
