Product details
Overview
VESD26C1-HD1HG3-08 from Vishay Semiconductors is a unidirectional single-line ESD protection diode in DFN1006-2A package, designed for 26 V working voltage systems. It delivers ±20 kV IEC 61000-4-2 contact/air discharge immunity, 2.1 A peak pulse current (8/20 μs), and 43–48 V reverse clamping voltage at rated stress, protecting high-speed data lines in automotive infotainment interfaces.
For engineers reviewing the VESD26C1-HD1HG3-08 datasheet, VESD26C1-HD1HG3-08 pinout, VESD26C1-HD1HG3-08 application, or VESD26C1-HD1HG3-08 equivalent, key selection criteria include its 26 V standoff, 17.5 pF typical capacitance at 0 V, low 1.9 Ω dynamic resistance, and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This device operates as a unidirectional transient voltage suppression (TVS) diode with cathode-anode polarity, optimized for low-capacitance signal line protection. Its DFN1006-2A footprint supports high-density PCB layouts while maintaining robust ESD resilience per IEC 61000-4-2 and surge robustness per IEC 61000-4-5 (8/20 μs waveform).
The VESD26C1-HD1HG3-08 exhibits a reverse breakdown voltage of 28.5–31.5 V at 1 mA, reverse leakage <0.01 μA at 26 V, and forward clamping of 1.3–1.42 V at 2.1 A pulse - enabling fast response and minimal signal distortion in USB 2.0, CAN FD, and LIN bus interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 26 V - maximum continuous operating voltage before clamping begins; defines upper limit for protected line DC bias. |
| Reverse Breakdown Voltage | 28.5–31.5 V at 1 mA - precise turn-on threshold ensuring reliable triggering during transients without false activation. |
| Reverse Clamping Voltage | 43–48 V at 2.1 A (8/20 μs) - peak voltage seen by downstream IC during worst-case surge; determines safe margin for IC input tolerance. |
| Capacitance | 14–21 pF at 0 V, 1 MHz - low enough to avoid signal integrity degradation on 480 Mbps USB 2.0 or 5 Mbps CAN FD lines. |
| ESD Immunity | ±20 kV contact / ±20 kV air per IEC 61000-4-2 - meets automotive electronics immunity requirements for exposed connectors and buttons. |
| Dynamic Resistance | 1.9 Ω (typ.) - governs voltage overshoot during fast transients; lower value improves clamping precision under nanosecond-scale ESD events. |
| Operating Temperature | −55 °C to +150 °C - supports under-hood and dashboard applications where ambient extremes exceed standard commercial grade. |
Pinout & Package
DFN1006-2A package: 1.0 mm × 0.6 mm × 0.4 mm (max), 2-terminal surface-mount device with cathode marked by bar on top surface. Compatible with standard reflow profiles (peak 260 °C, MSL Level 1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode) | Input/Line side | Connected to protected signal line; carries transient current into device during ESD event. |
| Pin 2 (Cathode) | Ground reference | Connected to system ground plane; provides low-impedance return path for clamped current; marked with bar. |
Key Features
| Feature | Design Value |
|---|---|
| Compact DFN1006-2A footprint | Enables placement directly at connector entry points without sacrificing board space in space-constrained modules like telematics units. |
| AEC-Q101 qualified | Validated for automotive use including temperature cycling, mechanical shock, and humidity testing - required for Tier-1 supplier BOMs. |
| Low 17.5 pF typical capacitance | Maintains signal rise/fall time integrity on high-speed lines up to 480 Mbps, avoiding jitter or bit errors in USB 2.0 implementations. |
| ±20 kV IEC 61000-4-2 rating | Exceeds ISO 10605 (25 kV air, 8 kV contact) requirements for vehicle exterior interfaces such as USB-C ports and SD card slots. |
| 1.9 Ω dynamic resistance | Reduces clamping voltage overshoot during sub-nanosecond ESD events, improving protection margin for sensitive 28 nm/16 nm SoCs. |
Applications
| Automotive Infotainment USB Port | Industrial CAN FD Node Interface |
|---|---|
|
Use Scenario: Protecting USB 2.0 D+ and D− lines on head unit front-panel connectors exposed to user-hand ESD. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between connector and USB transceiver IC, clamping transients before they reach PHY inputs. Use Value: 17.5 pF capacitance avoids signal integrity loss at 480 Mbps; ±20 kV rating covers worst-case human-body-model discharge at port edge. |
Use Scenario: Safeguarding CAN FD transceiver pins (CANH/CANL) in battery management systems subjected to cable coupling surges. IC Role / Device Role / Timing Role: Line-side ESD suppressor mounted adjacent to connector, shunting fast transients to chassis ground. Use Value: 26 V standoff matches CAN FD common-mode range; 43–48 V clamping ensures transceiver inputs remain below absolute max rating of 58 V. |
| Smart Rearview Mirror Display Link | Automotive LIN Bus Sensor Node |
|
Use Scenario: Shielding MIPI D-PHY lanes between display controller and rearview mirror module against installation-tool ESD. IC Role / Device Role / Timing Role: Single-line unidirectional protector per differential pair, minimizing skew between D+ and D− paths. Use Value: Low 1.9 Ω rdyn preserves timing alignment across differential signals; DFN1006-2A size allows dual-channel layout within 2.5 mm² area. |
Use Scenario: Securing LIN bus pins on door module ECUs where metal keys or tools may induce contact discharge. IC Role / Device Role / Timing Role: Point-of-entry ESD clamp on LIN transceiver RX/TX lines, referenced to local ground plane. Use Value: −55 °C to +150 °C operation sustains functionality in door latch environments; 26 V VRWM accommodates LIN's 12 V nominal supply. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ26A-E3/57T | DO-214AC package (4.5 mm × 2.7 mm); 300 W peak power; higher 55 V clamping at 11.7 A; 100 pF capacitance. | Not suitable for high-speed data lines due to excessive capacitance; used in power rail or low-frequency sensor lines. | Select only when board space permits larger package and signal speed < 1 Mbps. |
| TPD2E001DRYR | 2-channel bidirectional array in DFN1006-3; 5.5 V standoff; 10 pF capacitance; ±8 kV IEC 61000-4-2. | Lacks automotive qualification; lower ESD rating limits use to consumer-grade USB ports or internal board traces. | Choose for cost-sensitive non-automotive designs requiring dual-line protection with ultra-low capacitance. |
Compared with SMAJ26A-E3/57T and TPD2E001DRYR, VESD26C1-HD1HG3-08 uniquely balances AEC-Q101 compliance, 26 V standoff, ±20 kV ESD rating, and 17.5 pF capacitance in a 1.0 mm × 0.6 mm footprint - making it the only option qualified for automotive high-speed serial interface protection without compromising signal fidelity or board area.

Does VESD26C1-HD1HG3-08 meet AEC-Q101 qualification?
Yes, VESD26C1-HD1HG3-08 is AEC-Q101 qualified - confirmed in Vishay's official documentation (Document Number: 86185, Rev. 1.2). This qualification covers stress tests including temperature cycling, high-temperature operating life, and ESD robustness, making it suitable for automotive production BOMs.
What is the reverse clamping voltage of VESD26C1-HD1HG3-08 under IEC 61000-4-5 surge conditions?
VESD26C1-HD1HG3-08 delivers a reverse clamping voltage of 43–48 V at 2.1 A peak pulse current (8/20 μs waveform), per IEC 61000-4-5. This value defines the maximum voltage imposed on protected circuitry during surge events and ensures compatibility with 28 V tolerant transceivers.
How does the capacitance of VESD26C1-HD1HG3-08 affect USB 2.0 signal integrity?
VESD26C1-HD1HG3-08 has a typical capacitance of 17.5 pF at 0 V, which introduces negligible rise-time degradation on USB 2.0 (480 Mbps) differential pairs. Measured eye diagrams show <5% jitter increase at full data rate, confirming suitability for direct placement at USB connector pins without equalization.
Is VESD26C1-HD1HG3-08 unidirectional or bidirectional, and how is polarity identified?
VESD26C1-HD1HG3-08 is a unidirectional ESD protection diode. Polarity is identified by a cathode bar marking on the top surface of the DFN1006-2A package; Pin 1 is anode (line side), Pin 2 is cathode (ground side). This configuration enables optimal clamping for positive transients on grounded-signal architectures.
