Product details
Overview
VESD26C1-HD1-G3-08 from Vishay Semiconductors is a unidirectional ESD-protection diode in DFN1006-2A package, rated for 26 V reverse standoff voltage, 2.1 A peak pulse current (IEC 61000-4-5), and 20 kV contact/air ESD immunity (IEC 61000-4-2); used to safeguard high-speed data lines such as USB 2.0, HDMI, and automotive infotainment interfaces.
For engineers reviewing the VESD26C1-HD1-G3-08 datasheet, VESD26C1-HD1-G3-08 pinout, VESD26C1-HD1-G3-08 application, or VESD26C1-HD1-G3-08 equivalent, key selection criteria include clamping voltage (43–48 V at 2.1 A), ultra-low capacitance (14–21 pF), dynamic resistance (1.9 Ω), operating temperature range (–55 °C to +150 °C), and AEC-Q101 qualification status.
Technical Context
This device implements a single-line, unidirectional TVS structure optimized for low-capacitance transient suppression in space-constrained PCB layouts. Its DFN1006-2A footprint (1.0 mm × 0.6 mm, < 0.5 mm height) enables placement directly at I/O connectors without signal integrity degradation.
The diode features a silicon avalanche junction with tightly controlled breakdown (28.5–31.5 V at 1 mA) and low dynamic resistance (1.9 Ω), ensuring predictable clamping behavior under fast-rising ESD events. It meets IEC 61000-4-2 (±20 kV contact/air) and IEC 61000-4-5 (8/20 μs, 2.1 A) standards without derating across its full operating temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 26 V - maximum continuous DC or RMS voltage the line can withstand before clamping begins |
| Reverse Breakdown Voltage | 28.5–31.5 V at 1 mA - precise turn-on threshold ensures early clamping during transients |
| Clamping Voltage | 43–48 V at 2.1 A, 8/20 μs - limits downstream IC stress to safe levels during surge events |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD-protection diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ26A | DO-214AC package (4.5 mm × 2.7 mm), 300 W peak power, 43.5 V clamping at 5.8 A | Higher clamping voltage and larger footprint limit use on high-speed or space-constrained lines | Select for cost-sensitive industrial power rail protection where size and capacitance are secondary |
| TPD2E001DRYR | 2-channel, bidirectional, 12 pF, 15 kV ESD rating, DRY (X2SON-6) package | Lacks AEC-Q101 qualification and has lower ESD immunity than VESD26C1-HD1-G3-08 | Prefer for dual-line consumer USB ports requiring minimal capacitance, not automotive-grade reliability |
Compared with SMAJ26A and TPD2E001DRYR, VESD26C1-HD1-G3-08 uniquely combines AEC-Q101 qualification, 20 kV ESD rating, 14–21 pF capacitance, and DFN1006-2A footprint-making it the only option validated for compact, high-reliability automotive data-line protection.

FAQ
What is the maximum clamping voltage of the VESD26C1-HD1-G3-08 under IEC 61000-4-5 surge conditions?
The VESD26C1-HD1-G3-08 exhibits a maximum reverse clamping voltage of 48 V when subjected to a 2.1 A, 8/20 μs peak pulse current per IEC 61000-4-5. This value is measured at the device terminals and represents the upper bound of voltage seen by downstream circuitry during standardized surge events. The VESD26C1-HD1-G3-08 maintains this performance across its full operating temperature range.
Is the VESD26C1-HD1-G3-08 qualified for automotive applications?
Yes, the VESD26C1-HD1-G3-08 is AEC-Q101 qualified, confirming its suitability for automotive electronic systems including infotainment, body control modules, and ADAS sensor interfaces. This qualification covers stress testing for temperature cycling, humidity bias, mechanical shock, and ESD robustness-ensuring reliability in demanding vehicular environments. The VESD26C1-HD1-G3-08 datasheet explicitly lists AEC-Q101 compliance in its ordering information table.
What is the capacitance of the VESD26C1-HD1-G3-08 and how does it affect high-speed signal integrity?
The VESD26C1-HD1-G3-08 has a typical capacitance of 17.5 pF at 0 V and 1 MHz, with a guaranteed range of 14–21 pF. This ultra-low value minimizes signal attenuation and timing skew on high-speed lines such as USB 2.0 (480 Mbps) and HDMI TMDS channels. Unlike higher-capacitance alternatives, the VESD26C1-HD1-G3-08 avoids degrading eye diagrams or increasing bit error rates in real-world PCB layouts.
Does the VESD26C1-HD1-G3-08 support both contact and air discharge ESD testing per IEC 61000-4-2?
Yes, the VESD26C1-HD1-G3-08 is rated for ±20 kV contact discharge and ±20 kV air discharge per IEC 61000-4-2, tested over 10 pulses. This exceeds the IEC 61000-4-2 Level 4 requirement (±15 kV contact / ±15 kV air) and provides design margin for end-equipment certification. The VESD26C1-HD1-G3-08 achieves this performance using a low-dynamic-resistance silicon junction optimized for fast transient response.
What is the package type and soldering profile compatibility of the VESD26C1-HD1-G3-08?
The VESD26C1-HD1-G3-08 uses the DFN1006-2A package (1.0 mm × 0.6 mm, max height 0.5 mm) with Sn (e3) lead plating compatible with standard Pb-free reflow profiles. Its MSL Level 1 rating means floor life is unlimited, and peak temperature exposure up to 260 °C is permitted. The VESD26C1-HD1-G3-08 footprint aligns with IPC-7351B recommendations for 0402-sized components.
