Product details
Overview
VETH100A1DD1HG3-08 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) signal line protection. It features ±24 V working range, >100 V trigger voltage, <2 pF capacitance, 15 kV IEC 61000-4-2 contact discharge immunity, and AEC-Q101 qualification.
For engineers reviewing the VETH100A1DD1HG3-08 datasheet, VETH100A1DD1HG3-08 pinout, VETH100A1DD1HG3-08 application, or VETH100A1DD1HG3-08 equivalent, this device serves as a low-capacitance, high-trigger-voltage transient suppressor for unshielded twisted-pair automotive data lines where signal integrity and EMC compliance are critical.
Technical Context
The VETH100A1DD1HG3-08 implements a snap-back silicon avalanche structure optimized for fast response to ESD transients while maintaining ultra-low dynamic resistance (0.4 Ω typ.) and minimal clamping voltage rise under high-current TLP pulses (31 V at 1 A, 34 V at 10 A). Its bidirectional architecture enables symmetric protection of differential Ethernet pairs without polarity constraints.
Designed specifically for OPEN Alliance-compliant Automotive Ethernet, it meets IEEE 10BASE-T1S/100BASE-T1/1000BASE-T1 suppression requirements including mixed-mode S-parameter performance, RF immunity behavior, and damage-free operation after 1000 ESD pulses. The DFN1006-2B package with wettable flanks supports AOI-compatible solder joint inspection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Protection Type | Bidirectional single-line ESD suppressor - protects one differential pair line against ±15 kV contact discharge without polarity sensitivity. |
| Working Voltage (VRWM) | ±24 V - compatible with 10BASE-T1S/100BASE-T1 common-mode voltage ranges and automotive supply rail margins. |
| Trigger Voltage (VT) | >100 V - ensures no false triggering during normal Ethernet signaling or power-on transients. |
| Clamping Voltage (VC) | 31 V at 1 A TLP - limits induced voltage on protected line to safe levels for 100BASE-T1 transceivers during ESD events. |
| Capacitance (CD) | 1.7 pF typ. at 0 V / 1 MHz - preserves signal integrity up to 1 GHz with negligible insertion loss in 50 Ω systems. |
| ESD Immunity | ±15 kV contact discharge per IEC 61000-4-2 (150 pF/330 Ω) - exceeds OPEN Alliance requirement for 1000 pulses without degradation. |
| Dynamic Resistance (rdyn) | 0.4 Ω typ. - minimizes voltage overshoot under high-current ESD pulses and stabilizes clamping performance across current range. |
Pinout & Package
DFN1006-2B package: 1.0 mm × 0.6 mm × 0.4 mm max height, MSL level 1, Sn (e3) lead plating with wettable side walls for AOI inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode (cathode marking on top surface) | Connected to data line (e.g., ETH_P); polarity-insensitive due to bidirectional design - either pin may serve as line or ground terminal. |
| Pin 2 | Cathode (marked side) | Connected to system ground; forms low-impedance path for ESD current during snap-back conduction. |
Key Features
| Feature | Design Value |
|---|---|
| OPEN Alliance compliance | Validated for 10BASE-T1S, 100BASE-T1, and 1000BASE-T1 suppression per IEEE test specifications - enables drop-in use in certified automotive Ethernet designs. |
| Low capacitance & high bandwidth | 1.7 pF typical capacitance preserves signal rise/fall times and minimizes jitter on 10–1000 Mbps Ethernet links. |
| AEC-Q101 qualification | Qualified for automotive underhood and cabin environments - guaranteed operation from −55 °C to +150 °C junction temperature. |
| Wettable flank terminations | Sn (e3) plating extends to package sidewalls - enables automated optical inspection (AOI) of solder fillets without X-ray. |
| High trigger voltage stability | VT > 100 V ensures no conduction during normal mode noise, power sequencing, or RF coupling - avoids false clamping in noisy vehicle EMI environments. |
Applications
| 10BASE-T1S Sensor Network | 100BASE-T1 ADAS Camera Link |
|---|---|
Use Scenario: Unshielded twisted-pair connection between body control module and distributed sensors (e.g., door latch, seat position) in compact electric vehicle architectures. IC Role / Device Role / Timing Role: Bidirectional ESD suppressor placed inline between sensor PHY and connector, protecting against cable-borne transients during assembly and service. Use Value: Enables robust 10BASE-T1S operation at ≤10 Mbps with <1.7 pF loading - maintains timing margin for deterministic sensor polling without signal distortion. |

Use Value: Achieves 0.85 pF typical capacitance in series configuration - satisfies 1 Gbps signal integrity requirements while sustaining 15 kV ESD immunity. |
Use Scenario: Ethernet gateway bridging CAN FD, LIN, and 100BASE-T1 domains, exposed to external harness ESD risk at vehicle entry points. IC Role / Device Role / Timing Role: Primary-level ESD guard on all Ethernet ports before common-mode chokes and transceivers, absorbing bulk energy before downstream components. Use Value: Withstands repeated 15 kV discharges without parameter shift - eliminates field failures caused by connector hot-plug events or service technician static discharge. |
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 | Unidirectional, 5.5 V VRWM, 0.3 pF capacitance, 12 kV ESD rating | Targeted for low-voltage USB/MIPI interfaces - insufficient working voltage for 24 V automotive Ethernet common-mode range | Select only for sub-6 V data lines; not suitable for 10BASE-T1S/100BASE-T1 due to low VRWM and unidirectional architecture. |
| ON SEMICONDUCTOR NUF2060XV6T1G | Bidirectional, 12 V VRWM, 0.6 pF capacitance, AEC-Q101 qualified | Optimized for 12 V CAN/LIN bus protection - lacks OPEN Alliance validation and fails 100BASE-T1 clamping voltage targets | Acceptable for lower-speed automotive buses but does not meet 100BASE-T1/1000BASE-T1 clamping (<34 V @ 10 A) or capacitance requirements. |
Compared with RCLAMP0524P.TCT and NUF2060XV6T1G, the VETH100A1DD1HG3-08 uniquely combines ±24 V working range, >100 V trigger voltage, OPEN Alliance validation, and 1.7 pF capacitance - making it the only qualified solution for production 10BASE-T1S/100BASE-T1/1000BASE-T1 implementations requiring zero signal degradation and full automotive reliability.

FAQ
What is the maximum operating temperature for the VETH100A1DD1HG3-08?
The VETH100A1DD1HG3-08 has a junction temperature range of −55 °C to +150 °C and is rated for continuous operation across that full range. This specification is validated per AEC-Q101 stress testing and supports placement near high-temperature zones such as engine compartments or power inverters in electric vehicles. The DFN1006-2B package's low thermal resistance enables reliable heat dissipation even under sustained 24 V bias conditions.
Does the VETH100A1DD1HG3-08 require external biasing or control signals?
No, the VETH100A1DD1HG3-08 is a passive bidirectional ESD protection diode and requires no external biasing, control pins, or power supply. It operates solely based on its intrinsic snap-back characteristics - conducting only when transient voltage exceeds its >100 V trigger threshold. This simplifies PCB layout and eliminates risk of control logic failure in safety-critical automotive systems.
How does the VETH100A1DD1HG3-08 achieve OPEN Alliance compliance for 1000BASE-T1?
The VETH100A1DD1HG3-08 achieves OPEN Alliance compliance for 1000BASE-T1 through two-device series configuration, which reduces total capacitance to 0.85 pF (typ.), well below the 1.0 pF limit. Its clamping voltage remains ≤34 V at 10 A TLP, satisfying transient suppression thresholds, and its mixed-mode S-parameters pass insertion loss and return loss requirements across 1–1000 MHz per IEEE 802.3bp test plans.
Is the VETH100A1DD1HG3-08 pin-compatible with other Vishay DFN1006-2B ESD diodes?
Yes, the VETH100A1DD1HG3-08 shares identical DFN1006-2B mechanical footprint and pin assignment (anode/cathode) with Vishay's VETHxxxA1DD1 family, including VETH80A1DD1HG3-08 and VETH150A1DD1HG3-08. However, electrical parameters differ - notably VRWM (24 V), VT (>100 V), and VC - so substitution requires verification against system-level ESD and signal integrity requirements.
What is the leakage current specification for the VETH100A1DD1HG3-08 at maximum working voltage?
At VR = 24 V, the VETH100A1DD1HG3-08 exhibits a typical leakage current of 0.001 μA with a maximum of 0.1 μA. This ultralow leakage ensures negligible DC loading on Automotive Ethernet lines, preserving common-mode voltage stability and preventing false wake-up events in low-power sleep modes required by ISO 11898-2 and OPEN Alliance power management profiles.
