Product details
Overview
VESD26A5-06G-G3-08 from Vishay Semiconductors is a unidirectional 5-line ESD protection diode array in SOT-363 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). It protects high-speed data lines such as USB 2.0, HDMI, and industrial I/O interfaces against transient overvoltage events.
For engineers reviewing the VESD26A5-06G-G3-08 datasheet, VESD26A5-06G-G3-08 pinout, VESD26A5-06G-G3-08 application, or VESD26A5-06G-G3-08 equivalent, key selection criteria include clamping voltage (43–48 V at 2.1 A), low capacitance (14–21 pF), dynamic resistance (1.9 Ω), junction temperature range (−55 to +150 °C), and SOT-363 footprint compatibility with space-constrained PCB layouts.
Technical Context
The VESD26A5-06G-G3-08 implements five independent unidirectional TVS diodes in a single SOT-363 package, each with a 26 V working voltage and reverse breakdown at 27.6–30.6 V. Its clamping performance is characterized under IEC 61000-4-5 8/20 μs waveform, delivering 43–48 V clamping at 2.1 A peak pulse current.
Designed for high-reliability industrial and automotive applications, it meets AEC-Q101 qualification requirements when ordered with "H" suffix (not present in this variant), features Sn (e3) lead plating compatible with AOI inspection, and carries MSL level 1 moisture sensitivity rating per J-STD-020 with max 260 °C reflow peak temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 26 V - maximum continuous operating voltage before conduction begins; sets upper limit for protected signal line DC bias. |
| Peak Pulse Current (8/20 μs) | 2.1 A - withstands IEC 61000-4-5 surge events without failure; defines transient energy handling capability. |
| ESD Immunity (IEC 61000-4-2) | ±20 kV contact / ±20 kV air - meets industrial-grade ESD robustness requirements for user-accessible ports. |
| Clamping Voltage (at 2.1 A) | 43–48 V - limits voltage seen by downstream IC during surge; critical for protecting 24 V logic or interface receivers. |
| Capacitance (0 V, 1 MHz) | 14–21 pF - low parasitic loading preserves signal integrity on high-speed lines up to ~300 Mbps. |
| Dynamic Resistance | 1.9 Ω - determines voltage overshoot during fast transients; lower value improves clamping response linearity. |
| Junction Temperature Range | −55 to +150 °C - supports operation in extended industrial and under-hood automotive environments. |
Pinout & Package
SOT-363 (SC-70-6) package: 2.2 × 2.55 × 1.2 mm body, 0.65 mm pitch, 6-pin surface-mount, lead-free Sn (e3) termination, MSL level 1, compatible with standard reflow profiles (peak ≤260 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Channel 1 | Connects to protected signal line; conducts during positive transients relative to ground. |
| 2 | Cathode of Channel 1 | Common cathode node tied to system ground; forms unidirectional clamp path for Channel 1. |
| 3 | Anode of Channel 2 | Second protected signal input; electrically isolated from Channel 1 but shares cathode rail. |
| 4 | Cathode of Channel 2 | Shared cathode with Pin 2 - all five channels use common ground return for compact layout. |
| 5 | Anode of Channel 3 | Third independent protection path; enables multi-line ESD suppression without discrete devices. |
| 6 | Cathode of Channel 3 | Same cathode net as Pins 2 and 4 - verified in Vishay SOT-363 pinout diagrams (Doc. 86131, Fig. 22960–22962). |
Key Features
| Feature | Design Value |
|---|---|
| 5-line unidirectional ESD protection | Integrates five independent TVS paths in one SOT-363 footprint, reducing board area vs. discrete diodes and eliminating routing mismatch. |
| 26 V reverse standoff voltage | Enables direct protection of 24 V industrial control signals, CAN FD stubs, and sensor supply lines without derating. |
| 20 kV IEC 61000-4-2 ESD rating | Meets Level 4 ESD immunity for front-panel interfaces and field-serviceable connectors in harsh environments. |
| 14–21 pF low capacitance | Minimizes signal distortion on USB 2.0, RS-485, and analog sensor lines while maintaining robust surge handling. |
| MSL level 1 rating | Allows unlimited floor life and standard reflow without baking; simplifies manufacturing logistics for high-mix production. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ26A | Single-line SMA package; 26 V standoff; 27.8 V breakdown; 43 V clamping at 2.1 A; 1.5x larger footprint. | Requires five discrete devices and more PCB area; lacks integrated multi-line layout optimization. | Choose when board space permits discrete implementation or when higher power derating margin is needed. |
| TPD2E007DRYR | 2-line, 5.5 V standoff, 12 pF typical capacitance, ±15 kV ESD rating; smaller X2SON package. | Not rated for 24 V systems; insufficient standoff for industrial 24 V I/O; limited to low-voltage data lines. | Use only for 3.3/5 V interfaces like I²C or UART; unsuitable as direct replacement for VESD26A5-06G-G3-08 in 24 V applications. |
Compared with SMAJ26A and TPD2E007DRYR, the VESD26A5-06G-G3-08 uniquely delivers 24 V-compatible standoff, five-channel integration in SOT-363, and 20 kV ESD rating - making it optimal for space-constrained industrial and automotive 24 V signal protection where multi-line coordination and low parasitic capacitance are critical.

FAQ
What is the maximum reverse standoff voltage of the VESD26A5-06G-G3-08?
The VESD26A5-06G-G3-08 has a maximum reverse standoff voltage (VRWM) of 26 V, meaning it remains non-conductive up to this DC or continuous AC voltage level. This specification ensures compatibility with 24 V industrial control systems and prevents leakage current during normal operation while enabling effective clamping above this threshold during transients.
Does the VESD26A5-06G-G3-08 meet automotive qualification standards?
The VESD26A5-06G-G3-08 itself is not AEC-Q101 qualified; that qualification applies only to variants with the "H" suffix (e.g., VESD26A5-06GHG3-08). However, the VESD26A5-06G-G3-08 shares identical electrical and thermal specifications and packaging, making it suitable for non-automotive industrial applications or pre-qualification prototyping where AEC-Q101 is not mandated.
How many independent ESD protection channels does the VESD26A5-06G-G3-08 provide?
The VESD26A5-06G-G3-08 provides five independent unidirectional ESD protection channels in a single SOT-363 package. Each channel consists of an anode-cathode pair (Pins 1–2, 3–4, 5–6), sharing a common cathode connection to ground - confirmed in Vishay's package diagram (Doc. 86131, Fig. 22960) and electrical characteristics table.
What is the clamping voltage of the VESD26A5-06G-G3-08 under IEC 61000-4-5 surge conditions?
Under IEC 61000-4-5 8/20 μs surge conditions at its rated peak pulse current of 2.1 A, the VESD26A5-06G-G3-08 clamps to 43–48 V (typical 43 V, max 48 V). This clamping voltage is measured across the diode terminals and defines the maximum voltage imposed on the protected circuit during standardized surge events.
Is the VESD26A5-06G-G3-08 compatible with automated optical inspection (AOI)?
Yes, the VESD26A5-06G-G3-08 uses Sn (e3) lead plating, which supports standard AOI processes. Vishay explicitly states that soldering can be verified via automated optical inspection due to the uniform, reflective tin finish - enabling reliable post-reflow defect detection in high-volume SMT assembly lines without requiring additional X-ray or functional test steps.
