Product details
Overview
VESD26A5-06GHG3-08 from Vishay Semiconductors is a 5-line unidirectional ESD protection diode array in SOT-363 package, designed for high-voltage I/O line protection with 26 V reverse standoff voltage, ±20 kV IEC 61000-4-2 contact discharge immunity, and 100 W peak pulse power rating. It safeguards USB 2.0, HDMI, and industrial sensor interfaces against electrostatic discharge events.
For engineers reviewing the VESD26A5-06GHG3-08 datasheet, VESD26A5-06GHG3-08 pinout, VESD26A5-06GHG3-08 application, or VESD26A5-06GHG3-08 equivalent, this device delivers verified clamping performance (VC = 43–48 V at 2.1 A), low dynamic resistance (1.9 Ω), and ultra-low capacitance (14–21 pF) critical for high-speed signal integrity in automotive infotainment and industrial HMI designs.
Technical Context
This device implements five independent unidirectional TVS diodes in a single SOT-363 package, each configured as a cathode-anode pair referenced to common ground. Its architecture enables simultaneous protection of five signal lines without cross-coupling, supporting bidirectional data paths via discrete grounding per channel.
Rated for operation from –55 °C to +150 °C and qualified to AEC-Q101 when specified (e.g., VESD26A5-06GHG3-08 includes "H" suffix denoting AEC-Q101 qualification), it features Sn (e3) lead plating compatible with automated optical inspection and peak reflow up to 260 °C per J-STD-020 MSL level 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage (VRWM) | 26 V - Maximum continuous operating voltage before clamping begins; sets upper limit for protected signal swing. |
| Reverse Clamping Voltage (VC) | 43–48 V at 2.1 A (8/20 μs) - Peak voltage seen by downstream IC during ESD event; ensures safe margin below 50 V logic thresholds. |
| Capacitance (CD) | 14–21 pF at 0 V, 1 MHz - Low enough to avoid signal degradation on USB 2.0 (480 Mbps) and HDMI 1.4 TMDS channels. |
| ESD Immunity | ±20 kV contact / ±20 kV air (IEC 61000-4-2) - Meets automotive and industrial ESD robustness requirements for exposed connectors. |
| Peak Pulse Power (PPP) | 100 W (8/20 μs) - Sustains transient energy from lightning-induced surges or system-level EFT events without failure. |
| Dynamic Resistance (rdyn) | 1.9 Ω (TLP, 100 ns) - Low impedance limits voltage overshoot during fast-rising ESD transients (<1 ns rise time). |
Pinout & Package
SOT-363 (SC-70-6) package: 2.25 mm × 2.55 mm × 1.20 mm body, 0.65 mm pitch, gull-wing leads, MSL level 1, Sn (e3) termination, 3000 pcs/reel (8 mm tape, green, -08 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Channel 1 | Input node for first protected signal line; connects to I/O trace prior to connector or interface IC. |
| 2 | Cathode of Channel 1 | Ground return path for Channel 1; must connect to low-inductance chassis or signal ground plane. |
| 3 | Anode of Channel 2 | Input node for second protected signal line; electrically isolated from other channels. |
| 4 | Cathode of Channel 2 | Shared ground terminal with Pins 2 and 6; enables compact layout with single ground pour. |
| 5 | Anode of Channel 3 | Input node for third protected signal line; supports independent routing without crosstalk coupling. |
| 6 | Cathode of Channel 3 | Shared ground terminal (Pins 2, 4, 6); reduces PCB ground loop inductance across all five channels. |
Key Features
| Feature | Design Value |
|---|---|
| 5-line unidirectional ESD protection | Enables full protection of multi-lane interfaces (e.g., USB D+/D−, HDMI TX0+/TX0−, and CEC) in one footprint. |
| 26 V working range | Supports 24 V industrial control I/O, CAN FD physical layer biasing, and automotive LIN bus receivers without over-clamping. |
| Low 14–21 pF capacitance | Maintains <0.1 dB insertion loss at 500 MHz, preserving eye diagram integrity for USB 2.0 and SDIO applications. |
| AEC-Q101 qualified (H suffix) | Validated for automotive under-hood and infotainment environments including temperature cycling, humidity, and mechanical shock. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMF26A-SOD123 | Single-line SOD-123 package; 26 V VRWM; 20 kV ESD rating; higher 45 pF capacitance. | Requires five discrete devices for same channel count; unsuitable for space-constrained USB/HDMI layouts. | Select when cost-per-channel is prioritized over board area and signal integrity. |
| TPD2E001DRYR | 5-line unidirectional array in USON-6; 5 V VRWM; 12 pF capacitance; ±8 kV contact rating. | Limited to 5 V systems; insufficient for 24 V industrial or automotive 12/24 V domains. | Select only for low-voltage consumer electronics where 26 V standoff is unnecessary. |
Compared with SMF26A-SOD123 and TPD2E001DRYR, VESD26A5-06GHG3-08 uniquely balances 26 V standoff, ±20 kV ESD immunity, and 14–21 pF capacitance in a single SOT-363 footprint-enabling compact, high-reliability protection for mixed-voltage industrial and automotive interfaces without compromising signal fidelity.

FAQ
What is the maximum operating temperature range for VESD26A5-06GHG3-08?
VESD26A5-06GHG3-08 operates reliably from –55 °C to +150 °C junction temperature, meeting extended thermal requirements for under-hood automotive and industrial control cabinet deployments. This range is validated per AEC-Q101 stress testing protocols and applies to both steady-state and transient thermal conditions during ESD events.
Does VESD26A5-06GHG3-08 support bidirectional signal lines like USB D+ and D−?
VESD26A5-06GHG3-08 is a unidirectional array, but it protects bidirectional signals by placing anode-to-signal and cathode-to-ground on each line-clamping positive transients to ground while blocking reverse leakage. For true bidirectional protection, two VESD26A5-06GHG3-08 devices per differential pair would be required, though its 26 V VRWM makes it suitable for asymmetric biasing in USB 2.0 applications.
How does the "H" in VESD26A5-06GHG3-08 indicate AEC-Q101 qualification?
The "H" in VESD26A5-06GHG3-08 is Vishay's ordering code suffix denoting full AEC-Q101 qualification, including stress tests for temperature cycling, high-temperature operating life, ESD, and mechanical shock. This differs from non-H variants (e.g., VESD26A5-06GG3-08), which lack automotive-grade validation and are intended for commercial applications only.
Can VESD26A5-06GHG3-08 replace VESD12A5-06GHG3-08 in a 12 V system?
VESD26A5-06GHG3-08 may be used in 12 V systems, but its 26 V VRWM increases clamping voltage margin versus VESD12A5-06GHG3-08 (12 V VRWM). While safe, it yields higher VC (43–48 V vs. 20.5–22.7 V), potentially exceeding downstream IC absolute maximum ratings. Use only if system-level analysis confirms sufficient voltage headroom exists.
What is the meaning of the "-08" suffix in VESD26A5-06GHG3-08?
The "-08" suffix in VESD26A5-06GHG3-08 specifies packaging: green, lead (Pb)-free, Sn (e3) termination, 3000 pieces per 7-inch reel on 8 mm carrier tape. This matches industry-standard automated pick-and-place requirements and complies with RoHS Directive 2011/65/EU Annex II exemptions.
