Product details
Overview
VETH100A1DD1 from Vishay Semiconductors is a single-line bidirectional ESD-protection diode in DFN1006-2B package, designed for Automotive Ethernet (10BASE-T1S/100BASE-T1/1000BASE-T1) data lines. It provides ±15 kV IEC 61000-4-2 ESD immunity, clamps at ≤31 V (ITLP = 1 A), features <2 pF capacitance at 1 MHz, and operates across ±24 V working range with trigger voltage >100 V.
For engineers reviewing the VETH100A1DD1 datasheet, VETH100A1DD1 pinout, VETH100A1DD1 application, or VETH100A1DD1 equivalent, this page delivers verified electrical specs, OPEN Alliance compliance details, low-capacitance signal integrity impact, and AEC-Q101-qualified automotive deployment guidance.
Technical Context
The VETH100A1DD1 employs snap-back silicon avalanche structure to achieve high trigger voltage (>100 V) and low dynamic resistance (0.4 Ω typ.), enabling robust clamping of fast ESD transients without affecting signal integrity. Its bidirectional operation protects both polarities of unshielded twisted-pair Ethernet lines.
Designed specifically for OPEN Alliance-compliant Automotive Ethernet, it meets IEEE 10BASE-T1S/100BASE-T1/1000BASE-T1 EMC suppression requirements, including mixed-mode S-parameter validation and RF immunity testing. Capacitance is specified at 1.7 pF (typ.) at 0 V bias and further reduced to 0.85 pF (typ.) when two devices are used in series per OPEN Alliance recommendations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Clamping Voltage | 31 V max at ITLP = 1 A (100 ns pulse); limits transient overvoltage to safe levels for 100BASE-T1 transceivers |
| Capacitance | 1.7 pF typ. at 0 V, 1 MHz; preserves signal integrity up to 1 Gbps on automotive Ethernet links |
| Working Voltage | ±24 V max VRWM; supports common-mode voltage swing in One-Pair Ethernet bus under load dump conditions |
| Trigger Voltage | >100 V VT (TLP, 1 A); prevents false triggering during normal signal activity or power-up transients |
| Dynamic Resistance | 0.4 Ω typ.; ensures stable clamping performance across varying ESD current magnitudes |

Applications
| Automotive Ethernet Node Protection | 10BASE-T1S Sensor Network Interface |
|---|---|
Use Scenario: Protecting PHY-level data lines in ADAS domain controllers exposed to ESD events during vehicle assembly or service. IC Role / Device Role / Timing Role: Bidirectional ESD clamp between differential pair and chassis ground, placed within 5 mm of connector. Use Value: Prevents latch-up or damage to 100BASE-T1 transceivers while maintaining <1.7 pF loading for clean eye diagrams at 100 Mbps. | Use Scenario: Securing low-speed sensor nodes (e.g., tire pressure, seat occupancy) connected via 10BASE-T1S unshielded twisted pair. IC Role / Device Role / Timing Role: Line-to-ground ESD suppressor on single-ended or differential signaling paths in battery-powered ECUs. Use Value: Enables reliable operation at ±24 V common-mode range and survives 1000× contact discharges without parameter shift. |

IC Role / Device Role / Timing Role: Secondary ESD barrier downstream of common-mode chokes, supplementing primary CMC filtering. Use Value: Reduces risk of ESD-induced bit errors during high-dV/dt switching events by limiting peak line voltage to safe thresholds. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD-protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SEMTECH RCLAMP0524P.TCT | 0.5 pF lower typical capacitance (1.2 pF), but lower trigger voltage (70 V) and no OPEN Alliance validation | Preferred for non-Automotive USB/MIPI interfaces; not qualified for 100BASE-T1 EMC stress tests | Select only if signal bandwidth exceeds 2 GHz and automotive qualification is unnecessary |
| ON Semiconductor ESD9X5.0ST5G | Higher clamping voltage (40 V at 1 A), larger SOD-523 package (1.7 × 1.3 mm), AEC-Q101 qualified but not OPEN Alliance tested | Suitable for legacy CAN/LIN protection; lacks low-capacitance optimization for 100+ Mbps Ethernet | Choose when board space allows larger footprint and 10BASE-T1S compliance is not required |
Compared with RCLAMP0524P.TCT and ESD9X5.0ST5G, the VETH100A1DD1 uniquely combines OPEN Alliance validation, sub-2 pF capacitance, >100 V trigger, and DFN1006-2B size-making it the only option qualified for production 10BASE-T1S/100BASE-T1 nodes requiring zero-layout compromise.

FAQ
What is the maximum operating temperature range for the VETH100A1DD1?
The VETH100A1DD1 has a junction temperature range of -55 °C to +150 °C, fully compliant with AEC-Q101 requirements for under-hood automotive applications. This rating is validated per J-STD-020 MSL level 1 reflow profile with peak temperature up to 260 °C, ensuring reliability in high-thermal-stress environments where the VETH100A1DD1 is deployed near power electronics or engine control modules.
Does the VETH100A1DD1 require external biasing or control signals?
No, the VETH100A1DD1 is a passive bidirectional ESD protection diode that operates without any external bias, control pins, or power supply. It functions solely through its intrinsic snap-back avalanche characteristics-triggering only during ESD events exceeding ±100 V-and remains transparent to normal signal traffic on Automotive Ethernet lines, making the VETH100A1DD1 ideal for drop-in integration into existing PHY interface designs.
How does the VETH100A1DD1 meet OPEN Alliance 10BASE-T1S requirements for capacitance?
The VETH100A1DD1 achieves OPEN Alliance 10BASE-T1S compliance by specifying 0.85 pF typical capacitance when two devices are placed in series on differential lines-verified per OPEN Alliance test methodology. This configuration reduces effective line loading below 1 pF, minimizing signal distortion at 10 Mbps while maintaining full ±15 kV ESD immunity, a capability confirmed in official test reports available upon request for the VETH100A1DD1.
Is the VETH100A1DD1 pin-compatible with other Vishay DFN1006-2B ESD diodes?
Yes, the VETH100A1DD1 shares identical DFN1006-2B footprint and pinout (anode/cathode) with Vishay's VETHxxxA1DD1 family members, such as VETH75A1DD1 and VETH150A1DD1. However, electrical parameters-including trigger voltage, clamping level, and working voltage-differ across variants; therefore, direct substitution requires verification of system-level ESD and signal integrity requirements before replacing the VETH100A1DD1.
Can the VETH100A1DD1 be used in non-automotive Ethernet applications like industrial IoT?
Yes, the VETH100A1DD1 is technically suitable for industrial Ethernet applications requiring high ESD immunity and low capacitance, including 100BASE-TX or custom single-pair links. Its ±24 V working range, 1.7 pF capacitance, and robust clamping performance make it viable outside automotive contexts-but users must validate electromagnetic compatibility and thermal derating independently, as the VETH100A1DD1's OPEN Alliance and AEC-Q101 qualifications are specific to automotive use cases.
