Product details
Overview
VESD24E1-HD1HG3-08 from Vishay Semiconductors is a single-line unidirectional ESD-protection diode in DFN1006-2A package, rated for 24 V reverse standoff voltage, 30 kV IEC 61000-4-2 contact/air discharge immunity, and 35 V typical clamping voltage at 4 A (8/20 μs), deployed in automotive infotainment data lines and industrial sensor interfaces.
For engineers reviewing the VESD24E1-HD1HG3-08 datasheet, VESD24E1-HD1HG3-08 pinout, VESD24E1-HD1HG3-08 application, or VESD24E1-HD1HG3-08 equivalent, key selection criteria include its 28 pF capacitance at 0 V, AEC-Q101 qualification status, 0.5 mm max height, low dynamic resistance (0.33 Ω), and compatibility with automated optical inspection due to Sn-plated exposed lead frame sidewalls.
Technical Context
This device operates as a transient voltage suppression (TVS) diode optimized for high-speed signal line protection. Its unidirectional architecture enables precise clamping above 24 V while maintaining sub-1 μA leakage at rated VRWM, and its DFN1006-2A footprint supports dense PCB layouts in space-constrained modules.
The VESD24E1-HD1HG3-08 delivers robust surge handling per IEC 61000-4-5 (175 W peak pulse power, 8/20 μs) and ISO 10605 (30 kV, 330 pF/330 Ω), with TLP-measured clamping stability (35 V at 16 A, 100 ns) and temperature-stable breakdown (24.5–33 V over −40 °C to +150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - Maximum continuous operating voltage before clamping begins; sets safe margin for 24 V rail protection. |
| Clamping Voltage (8/20 μs) | 35–41 V at 4 A - Limits downstream IC voltage stress during surge events without disrupting normal signal integrity. |
| Capacitance (0 V, 1 MHz) | 28–31 pF - Low enough to avoid signal degradation on USB 2.0, CAN FD, or LVDS lines up to ~100 MHz. |
| ESD Immunity | ±30 kV contact & air (IEC 61000-4-2) - Meets automotive EMC requirements for exposed connectors and ports. |
| Dynamic Resistance | 0.33 Ω - Enables fast, low-voltage overshoot response during fast-rising transients like ESD. |
| Package | DFN1006-2A (1.0 × 0.6 × 0.5 mm) - Enables placement directly at connector entry points with minimal trace inductance. |
Pinout & Package
DFN1006-2A package: 1.0 mm × 0.6 mm body, 0.5 mm max height, Sn-plated exposed lead frame sidewalls, MSL level 1, compatible with standard reflow profiles (peak ≤ 260 °C). Cathode marked by bar on side of package.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Connected to protected signal line; forward-biased during negative transients. |
| Pin 2 | Cathode | Connected to ground plane; defines clamping reference and conduction path for positive surges. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress per JESD47. |
| Low-profile DFN1006-2A | 0.5 mm max height enables integration beneath connectors and in ultra-thin modules (e.g., ADAS camera housings). |
| Sn-plated exposed sidewalls | Enables AOI-based solder joint verification without X-ray; reduces post-soldering inspection cost and cycle time. |
| 1-line unidirectional topology | Optimized for DC-biased signal paths (e.g., RS-485, CAN, LIN), minimizing capacitance vs. bidirectional alternatives. |
Applications
| Automotive Infotainment Display Interface | Industrial CAN FD Bus Node |
|---|---|
Use Scenario: Protecting HDMI or FPD-Link III differential pairs between head unit and display panel against ESD from user touchpoints. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed at connector entry to clamp transients before reaching serializer/deserializer ICs. Use Value: 28 pF capacitance avoids skew or attenuation on 1.5 Gbps links; 30 kV ESD rating exceeds ISO 10605 Class 4 requirements. | Use Scenario: Shielding CAN FD transceivers in factory automation controllers from coupling-induced surges on long cable runs. IC Role / Device Role / Timing Role: Line-side ESD suppressor on CAN_H/CAN_L lines, co-located with common-mode choke.

IC Role / Device Role / Timing Role: Low-leakage (≤0.05 μA) ESD clamp on ±10 V signal paths to preserve DC accuracy and offset stability. Use Value: Sub-1 μA IR at 24 V prevents loading of high-impedance sensor outputs; 24 V VRWM matches supply-referenced bias networks. | Use Scenario: Protecting Ethernet PHY interface pins on PoE-powered lighting controllers exposed to building-wide ESD events. IC Role / Device Role / Timing Role: Secondary-level ESD protection on MDI side, downstream of primary gas discharge tube or polymer TVS. Use Value: 175 W peak pulse power (8/20 μs) handles residual energy after upstream suppression; DFN1006-2A allows placement near RJ45 jack. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD-protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A-E3/57T | DO-214AC package (4.5 × 2.7 mm), higher clamping (43 V), 100 pF capacitance | Not suitable for high-speed data lines; intended for power rail or low-frequency signal protection | Select when board space permits larger footprint and lower capacitance is not required |
| TPD2E001DRSR | 2-channel bidirectional, 12 pF, 5 V VRWM, DFN1006-6 package | Designed for USB 2.0 or I²C; incompatible with 24 V working voltage requirement | Choose only for dual-line, low-voltage (<6 V), bidirectional signal protection |
Compared with SMAJ24A-E3/57T and TPD2E001DRSR, the VESD24E1-HD1HG3-08 uniquely balances 24 V operation, 28 pF capacitance, AEC-Q101 qualification, and ultra-small DFN1006-2A size-making it optimal for automotive and industrial high-speed signal line protection where space, voltage rating, and ESD robustness are jointly constrained.

FAQ
What is the maximum operating temperature range for the VESD24E1-HD1HG3-08?
The VESD24E1-HD1HG3-08 has a junction temperature range of −55 °C to +150 °C and a storage temperature range of −55 °C to +150 °C. This wide thermal envelope supports deployment in under-hood automotive modules and industrial environments with ambient extremes. The device maintains specified clamping performance and leakage current across this full range, as verified per AEC-Q101 stress testing protocols.
Is the VESD24E1-HD1HG3-08 qualified to AEC-Q101?
Yes, the VESD24E1-HD1HG3-08 is AEC-Q101 qualified. This qualification confirms that the device meets rigorous automotive reliability standards-including high-temperature reverse bias, temperature cycling, and ESD stress tests-making it suitable for use in automotive infotainment, ADAS, and body electronics. The "H" in the ordering code (VESD24E1-HD1HG3-08) explicitly denotes AEC-Q101 qualification.
What is the clamping voltage of the VESD24E1-HD1HG3-08 under an 8/20 μs surge?
The VESD24E1-HD1HG3-08 exhibits a typical clamping voltage of 35 V and a maximum of 41 V at 4 A under an 8/20 μs waveform per IEC 61000-4-5. This clamping behavior ensures protected ICs remain within their absolute maximum voltage ratings during surge events. The low dynamic resistance (0.33 Ω) contributes to tight clamping control and minimal overshoot.
Does the VESD24E1-HD1HG3-08 support automated optical inspection (AOI)?
Yes, the VESD24E1-HD1HG3-08 supports AOI due to its Sn-plated exposed sidewalls on the DFN1006-2A lead frame. This plating enables reliable visual detection of solder wetting and joint formation without requiring X-ray inspection. The feature reduces final test cost and improves yield in high-volume SMT assembly lines for automotive and industrial PCBs.
What is the capacitance of the VESD24E1-HD1HG3-08 at 0 V bias?
The VESD24E1-HD1HG3-08 has a typical capacitance of 28 pF and a maximum of 31 pF at 0 V reverse bias and 1 MHz. This low, well-controlled capacitance minimizes signal distortion on high-speed interfaces such as USB 2.0, CAN FD, and LVDS, enabling placement directly at connector entry points without compromising eye diagram integrity.
