Product details
Overview
PESD2ETH-D from Nexperia is an ultra-low-capacitance double rail-to-rail ESD protection diode in SOT457 (TSOP6) package, designed to protect two high-speed automotive Ethernet data lines (e.g., 100BASE-T1) against ±8 kV IEC 61000-4-2 ESD events. It integrates three ESD protection diodes - two rail-to-rail I/O paths and one VCC-to-ground path - enabling robust clamping (VCL = 11.8 V at 2.5 A) with only 1.3 pF capacitance per channel and AEC-Q101 qualification.
For engineers reviewing the PESD2ETH-D datasheet, PESD2ETH-D pinout, PESD2ETH-D application, or PESD2ETH-D equivalent, this device is selected for low-distortion, high-frequency signal line protection where sub-2 pF capacitance, <5.5 V reverse standoff voltage, and guaranteed operation across –55 °C to +150 °C ambient are critical in automotive Ethernet and LVDS interfaces.
Technical Context
The PESD2ETH-D implements a triple-diode architecture: two symmetrical rail-to-rail bidirectional diodes (pins 1–2 and 3–2, plus pins 4–2 and 6–2) provide differential ESD clamping on two independent high-speed channels, while a third Zener diode (pin 5–2) protects the VCC rail even under unpowered conditions. Its dynamic resistance is 1.1 Ω (positive clamping) and 0.9 Ω (negative clamping), ensuring fast transient response without signal degradation.
It operates within a 5.5 V reverse standoff voltage (VRWM) and delivers 11.8 V clamping voltage (VCL) at 2.5 A 8/20 µs pulse, with leakage current ≤100 nA at 5.5 V and forward voltage of 0.7 V at 1 mA - all verified per IEC 61000-4-2 and AEC-Q101 stress test requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5.5 V maximum reverse standoff voltage - ensures no conduction during normal 5 V system operation. |
| Cd (per channel) | 1.3 pF typical capacitance at 0 V bias - preserves signal integrity up to >1 GHz in 100BASE-T1 and LVDS links. |
| VCL | 11.8 V clamping voltage at 2.5 A 8/20 µs pulse - limits transient overvoltage to safe levels for PHY ICs. |
| IPPM | 2.5 A rated peak pulse current - withstands automotive-level surge transients without failure. |
| VESD | ±8 kV contact discharge per IEC 61000-4-2 - meets automotive ESD immunity requirements. |
| Tamb | –55 °C to +150 °C operating ambient range - supports under-hood and ADAS module deployment. |
| AEC-Q101 | Qualified for automotive discrete semiconductors - validated for reliability in harsh automotive environments. |
Pinout & Package
SOT457 (TSOP6) plastic surface-mounted package: 1.1 mm × 2.7 mm × 1.0 mm body, 0.95 mm lead pitch, 6-terminal lead frame with gull-wing leads. Compatible with standard reflow and wave soldering per IPC-7351B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I/O 1 (anode/cathode pair) | First protected high-speed data line terminal - bidirectionally clamped between pin 1 and GND (pin 2). |
| 2 | GND | Common reference and ESD return path - must be connected to low-inductance chassis ground. |
| 3 | I/O 2 (anode/cathode pair) | Second protected high-speed data line terminal - forms differential pair with pin 4 or 6. |
| 4 | I/O 2 (redundant path) | Alternate I/O 2 terminal - enables flexible PCB routing for differential signal pairs in TSOP6 layout. |
| 5 | VCC | Supply rail protection node - connects internal Zener diode to clamp VCC transients even when unpowered. |
| 6 | I/O 1 (redundant path) | Alternate I/O 1 terminal - supports symmetric layout of differential signals with minimal trace length asymmetry. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail bidirectional clamping | Enables protection of both positive and negative transients on high-speed differential lines without DC bias dependency. |
| 1.3 pF channel capacitance | Minimizes insertion loss and phase distortion in 100BASE-T1 (66.67 MHz fundamental, harmonics to 1 GHz). |
| VCC-to-GND Zener diode | Provides fail-safe ESD protection on power rail even when system is powered down or disconnected. |
| AEC-Q101 qualification | Validated for temperature cycling, HTRB, UHAST, and mechanical shock - required for automotive Tier-1 supply chain compliance. |
| 2.5 A peak pulse rating | Supports IEC 61000-4-5 Level 3 surge immunity (1 kV line-to-earth) when combined with common-mode chokes. |
Applications
| 100BASE-T1 Automotive Ethernet | Automotive LVDS Interfaces |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4201MR6T1G | Higher 3.5 pF capacitance per channel; single-rail architecture; no dedicated VCC clamp diode. | Limited to non-automotive LVDS or USB; not AEC-Q101 qualified. | Select only for cost-sensitive industrial designs where <2 pF is not required. |
| Vishay VEML6030X01 | Optical sensor IC - not an ESD diode; functionally incompatible. | N/A - incorrect device category. | Not a valid alternative; excluded from ESD protection selection. |
Compared with NUP4201MR6T1G, PESD2ETH-D delivers 63% lower capacitance and integrated VCC clamping for fail-safe operation, making it uniquely suitable for automotive Ethernet PHY protection where signal fidelity and unpowered robustness are mandatory.

FAQ
What is the maximum clamping voltage of PESD2ETH-D during an ESD event?
The PESD2ETH-D delivers a typical clamping voltage (VCL) of 11.8 V at 2.5 A peak pulse current (8/20 µs waveform), measured from I/O pins to GND. This value is confirmed per IEC 61000-4-2 testing and ensures downstream PHY ICs remain within their absolute maximum input voltage ratings during ±8 kV contact discharge events.
Can PESD2ETH-D protect signal lines when the system is unpowered?
Yes. The device includes a dedicated Zener diode between pin 5 (VCC) and pin 2 (GND), enabling clamping of transients on the supply rail even when VCC is at 0 V. This fail-safe behavior ensures protection remains active during power-down, hot-swap, or battery-disconnect scenarios common in automotive modules.
Is PESD2ETH-D compatible with automated optical inspection (AOI) after reflow?
Yes. The SOT457 package has gull-wing leads with 0.95 mm pitch and defined solder land geometry (per Fig. 11 in the datasheet), supporting reliable AOI detection of solder joint quality, coplanarity, and bridging. Its marking code "L8" is laser-etched and legible under standard AOI lighting and magnification.
How does the dual I/O pin configuration (pins 1/6 and 3/4) improve layout flexibility?
Pins 1 and 6 both serve as I/O 1 terminals, while pins 3 and 4 both serve as I/O 2 terminals - allowing symmetric routing of differential pairs without trace length mismatch. This redundancy reduces PCB layer count and improves impedance matching in tight-space automotive modules, directly supporting 100BASE-T1's strict <0.1 mm length-matching requirement.
