Product details
Overview
VESD12A5-06GHG3-08 from Vishay Semiconductors is a unidirectional 5-line ESD protection diode array in SOT-363, rated for 12 V reverse standoff voltage, ±30 kV IEC 61000-4-2 contact/air discharge, and 100 W peak pulse power, deployed for USB 2.0, HDMI, and industrial I/O port protection.
For engineers reviewing the VESD12A5-06GHG3-08 datasheet, VESD12A5-06GHG3-08 pinout, VESD12A5-06GHG3-08 application, or VESD12A5-06GHG3-08 equivalent, key selection criteria include clamping voltage at 4.4 A (20.5–22.7 V), dynamic resistance (0.4 Ω), capacitance (26–40 pF), and AEC-Q101 qualification status.
Technical Context
This device implements five independent unidirectional TVS diodes in a single SOT-363 package, each with cathode-anode orientation aligned to pin 1 as common cathode. It operates within -55 °C to +150 °C junction temperature range and supports automated optical inspection via Sn (e3) lead plating.
The protection architecture delivers low clamping under IEC 61000-4-5 8/20 μs surge (VC ≤ 22.7 V at IPP = 4.4 A) while maintaining sub-0.1 μA leakage at 12 V and 25 °C, enabling high-speed data line compatibility without signal integrity degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 12 V - maximum continuous operating voltage before conduction begins; sets upper limit for protected line DC bias. |
| Reverse Clamping Voltage | 20.5–22.7 V at 4.4 A, 8/20 μs - limits transient overvoltage seen by downstream ICs during ESD events. |
| Capacitance | 26–40 pF at 0 V, 1 MHz - low enough for <480 Mbps USB 2.0 and HDMI 1.4 signal integrity preservation. |
| ESD Immunity | ±30 kV contact / ±30 kV air per IEC 61000-4-2 - exceeds Level 4 immunity requirements for industrial and automotive interfaces. |
| Peak Pulse Power | 100 W at 8/20 μs - sustains multiple IEC 61000-4-5 surges without degradation. |
| Dynamic Resistance | 0.4 Ω (TLP, 100 ns) - ensures rapid voltage clamping response and minimal overshoot during fast transients. |
Pinout & Package
SOT-363 (SC-70-6) package: 2.2 × 2.55 × 1.2 mm body, 0.65 mm pitch, e3 Sn plating, MSL level 1, compatible with reflow up to 260 °C peak.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Common Cathode | Shared cathode node for all five diodes; connects to system ground or low-impedance return path. |
| 2 | Line 1 Anode | Input terminal for first protected line (e.g., USB D+); conducts to pin 1 during overvoltage. |
| 3 | Line 2 Anode | Input terminal for second protected line (e.g., USB D−); independent clamping path to pin 1. |
| 4 | Line 3 Anode | Input terminal for third protected line (e.g., HDMI TMDS clock); isolated from other anodes. |
| 5 | Line 4 Anode | Input terminal for fourth protected line (e.g., HDMI TMDS data 0); maintains channel independence. |
| 6 | Line 5 Anode | Input terminal for fifth protected line (e.g., HDMI TMDS data 1); enables full 5-line interface coverage. |
Key Features
| Feature | Design Value |
|---|---|
| 5-line unidirectional ESD protection | Enables simultaneous protection of multi-lane interfaces (e.g., USB 2.0 differential pair + ID/VBUS sense) without cross-talk or shared impedance paths. |
| AEC-Q101 qualified option | Validated for automotive subsystems requiring robustness across temperature cycling, humidity, and mechanical shock per AEC stress test protocols. |
| Low 26–40 pF capacitance | Preserves signal edge rate and eye diagram margin on high-speed lines up to 480 Mbps without equalization or layout compensation. |
| 0.4 Ω dynamic resistance | Minimizes clamping voltage overshoot during sub-nanosecond ESD transients, reducing risk of latch-up or gate oxide damage in connected ICs. |
| Sn (e3) lead finish | Supports AOI-based solder joint inspection and eliminates Pb-related compliance concerns for RoHS-compliant industrial and consumer designs. |
Applications
| USB 2.0 Interface Protection | HDMI 1.4 Port Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ12A | Single-line SMA package; 12 V VRWM; 30 kW peak power; 120 pF capacitance. | Requires five discrete devices for same channel count; unsuitable for high-speed data lines due to high capacitance. | Select when board space allows discrete placement and speed is not critical (e.g., power rail or low-speed GPIO). |
| TPD2E001DRYR | 5-line unidirectional array in SOT-563; 5 V VRWM; 12 pF capacitance; ±8 kV IEC 61000-4-2. | Limited to 5 V systems; lower ESD rating restricts use to consumer-grade interfaces without harsh environment exposure. | Prefer for USB OTG or mobile accessories where low capacitance outweighs ESD robustness requirements. |
Compared with SMAJ12A and TPD2E001DRYR, VESD12A5-06GHG3-08 uniquely combines 5-line integration, ±30 kV ESD immunity, 12 V standoff, and 26–40 pF capacitance in SOT-363-enabling compact, high-reliability protection for industrial and automotive high-speed interfaces without compromising signal fidelity or surge margin.

FAQ
What is the maximum operating temperature range for VESD12A5-06GHG3-08?
VESD12A5-06GHG3-08 has a junction temperature range of -55 °C to +150 °C and storage temperature range of -55 °C to +150 °C, making it suitable for under-hood automotive and industrial control cabinet deployments where thermal extremes occur.
Does VESD12A5-06GHG3-08 meet AEC-Q101 qualification?
VESD12A5-06GHG3-08 is offered in an AEC-Q101 qualified version (indicated by "H" in the ordering code), validated per stress test requirements for automotive electronics including temperature cycling, humidity, and mechanical shock.
What is the reverse leakage current specification for VESD12A5-06GHG3-08 at 12 V?
At VR = 12 V and Tamb = 25 °C, VESD12A5-06GHG3-08 exhibits reverse current IR of 0.01–0.1 μA, ensuring negligible power loss and no measurable impact on 12 V bias networks in protected circuits.
How does the clamping voltage of VESD12A5-06GHG3-08 compare to its 12 V standoff rating?
VESD12A5-06GHG3-08 clamps to 20.5–22.7 V at 4.4 A (8/20 μs), providing ~8.5–10.7 V of overvoltage margin above its 12 V working voltage-sufficient to protect 13.3 V tolerant receivers while avoiding false triggering during normal operation.
Can VESD12A5-06GHG3-08 be used for bidirectional signal lines like RS-485?
No-VESD12A5-06GHG3-08 is unidirectional and requires the protected line to remain positive relative to its common cathode (pin 1). For bidirectional interfaces such as RS-485, a symmetric (bidirectional) ESD array like VESD12B5-06G must be selected instead of VESD12A5-06GHG3-08.
