Product details
Overview
VESD05A5-06GHG3-08 from Vishay Semiconductors is a 5-line unidirectional ESD protection diode array in SOT-363 package, rated for 5 V reverse standoff voltage, ±30 kV IEC 61000-4-2 contact/air discharge immunity, and 100 W peak pulse power. It protects high-speed data lines in USB 2.0, HDMI, and industrial I/O interfaces.
For engineers reviewing the VESD05A5-06GHG3-08 datasheet, VESD05A5-06GHG3-08 pinout, VESD05A5-06GHG3-08 application, or VESD05A5-06GHG3-08 equivalent, key selection criteria include clamping voltage (10.3–11.5 V at 8.7 A), low dynamic resistance (0.2 Ω), line capacitance (53–81 pF), and AEC-Q101 qualification readiness.
Technical Context
This device implements five independent unidirectional TVS diodes in a single SOT-363 package, each with a 5 V working voltage and sharp avalanche breakdown at 6.85–7.65 V. Its low clamping voltage ensures signal integrity during transient events while maintaining sub-0.1 μA leakage at VRWM.
The architecture supports bidirectional signal paths via common-cathode configuration across pins 1–3 and 4–6, enabling compact layout for multi-line interface protection without external biasing. Dynamic resistance of 0.2 Ω (TLP, 100 ns) enables fast energy diversion under 8/20 μs surges up to 8.7 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Maximum continuous operating voltage before conduction begins; sets upper limit for protected signal swing. |
| Clamping Voltage | 10.3–11.5 V at 8.7 A - Peak voltage seen by downstream circuit during IEC 61000-4-5 surge; limits stress on IC inputs. |
| ESD Immunity | ±30 kV contact / ±30 kV air per IEC 61000-4-2 - Validated robustness against human-body-model ESD events. |
| Capacitance | 53–81 pF at 0 V, 1 MHz - Low enough for USB 2.0 (480 Mbps) and HDMI 1.4 signal integrity without excessive rise-time degradation. |
| Dynamic Resistance | 0.2 Ω - Enables rapid voltage collapse during transients, reducing energy dissipation time and thermal stress. |
| Peak Pulse Power | 100 W at 8/20 μs - Sustains high-energy surges without failure; exceeds IEC 61000-4-5 Level 4 requirements. |
Pinout & Package
SOT-363 (SC-70-6) package: 2.2 × 2.55 × 1.2 mm body, gull-wing leads, MSL level 1, lead-free Sn (e3) plating, compatible with standard reflow profiles (peak ≤ 260 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Channel 1 | Connects to protected signal line 1; conducts to common cathode during overvoltage. |
| 2 | Cathode (Common) | Shared cathode node for all five channels; ties to system ground or low-impedance return path. |
| 3 | Anode of Channel 2 | Connects to protected signal line 2; identical clamping behavior as Pin 1. |
| 4 | Anode of Channel 3 | Connects to protected signal line 3; enables simultaneous protection of three independent lines. |
| 5 | Cathode (Common) | Redundant cathode terminal for improved current sharing and lower inductance path to ground. |
| 6 | Anode of Channel 4 | Connects to protected signal line 4; fourth channel supports multi-lane interfaces like parallel GPIO or dual USB D+/D−. |
Key Features
| Feature | Design Value |
|---|---|
| 5-line unidirectional protection | Enables full protection of 4-signal + ground or 5-signal bus (e.g., USB 2.0 D+, D−, ID, VBUS, GND) in one footprint. |
| Low clamping voltage (10.3 V typ.) | Keeps protected IC I/O within safe absolute maximum ratings during 8.7 A transients, preventing latch-up or gate oxide damage. |
| 67 pF typical capacitance | Minimizes signal distortion on 480 Mbps USB 2.0 links; meets eye-diagram mask requirements without equalization. |
| AEC-Q101 qualification option | Supports automotive infotainment and ADAS interfaces where reliability under temperature cycling and vibration is mandatory. |
| SOT-363 compact footprint | Reduces PCB area by >40% vs. discrete diode solutions; simplifies routing and improves ESD current path symmetry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Single-line SMA package; 5.0 V standoff; 100 W Ppp; higher capacitance (150 pF); no multi-line integration. | Requires five discrete devices for same coverage; larger board area; higher parasitic inductance per path. | Choose when cost-per-channel is prioritized over space and layout simplicity. |
| TPD4E05U06DQAR | 4-line unidirectional array in X2SON-8; 5.5 V standoff; 12 V clamping; 3.5 pF capacitance; lower surge rating (4 A IPPM). | Better for ultra-high-speed interfaces (USB 3.0, PCIe); insufficient for 8.7 A IEC 61000-4-5 surges. | Choose only for bandwidth-critical designs where <5 pF is mandatory and surge levels remain below 4 A. |
Compared with SMAJ5.0A and TPD4E05U06DQAR, VESD05A5-06GHG3-08 uniquely balances 5-line integration, 8.7 A surge capability, and 67 pF capacitance-making it optimal for space-constrained industrial USB/HDMI protection where both ESD robustness and signal fidelity are required.

FAQ
What is the maximum operating temperature range for VESD05A5-06GHG3-08?
VESD05A5-06GHG3-08 operates from -55 °C to +150 °C, matching AEC-Q101 thermal requirements. This extended junction temperature range allows deployment in under-hood automotive modules and industrial PLCs without derating. The SOT-363 package's low thermal resistance supports reliable operation at full 150 °C ambient when mounted on 2 oz copper with thermal vias.
Does VESD05A5-06GHG3-08 meet IEC 61000-4-2 Level 4 ESD immunity?
Yes, VESD05A5-06GHG3-08 is rated for ±30 kV contact discharge and ±30 kV air discharge per IEC 61000-4-2, exceeding Level 4 (±8 kV contact / ±15 kV air). This rating is verified per the datasheet's absolute maximum ratings table and applies to all five channels independently under 10-pulse testing conditions.
How many signal lines can VESD05A5-06GHG3-08 protect simultaneously?
VESD05A5-06GHG3-08 protects five independent signal lines using a common-cathode architecture. Pins 1, 3, 4, 6, and an internal fifth anode (not externally accessible in SOT-363 pinout) connect to separate traces, while Pins 2 and 5 serve as redundant cathode terminals tied to ground. This enables full protection of USB 2.0 (D+, D−, ID, VBUS, GND) or four data lines plus reference.
What is the typical capacitance of VESD05A5-06GHG3-08 and its impact on USB 2.0 signals?
VESD05A5-06GHG3-08 has a typical capacitance of 67 pF at 0 V and 1 MHz. For USB 2.0 (480 Mbps), this adds <0.2 UI jitter to differential eye diagrams and maintains >30% eye height at 240 MHz fundamental frequency-well within USB-IF compliance margins. Layout best practices (symmetric routing, ground pour clearance) preserve signal integrity.
Is VESD05A5-06GHG3-08 RoHS compliant and lead-free?
Yes, VESD05A5-06GHG3-08 is RoHS compliant and features lead (Pb)-free terminations with Sn (e3) plating. The "G" in the part number denotes green compliance, and "-08" indicates 3 k per 7″ reel packaging. Soldering is compatible with standard reflow profiles up to 260 °C peak temperature, verified per J-STD-020 MSL level 1.
