Product details
Overview
VESD08A2-03G-G3-08 from Vishay Semiconductors is a dual-line unidirectional ESD-protection diode array in SOT-323 package, rated for 8 V reverse standoff voltage, 6.6 A peak pulse current (IEC 61000-4-5), and 30 kV ESD immunity (IEC 61000-4-2 contact/air discharge). It protects two signal lines in high-speed interfaces such as USB 2.0, HDMI, or automotive infotainment data links.
For engineers reviewing the VESD08A2-03G-G3-08 datasheet, VESD08A2-03G-G3-08 pinout, VESD08A2-03G-G3-08 application, or VESD08A2-03G-G3-08 equivalent, key selection factors include its 37–57 pF capacitance at 0 V, 13.7–15.3 V reverse clamping voltage at 6.6 A, and compatibility with automated optical inspection due to Sn (e3) lead plating.
Technical Context
This device implements a dual-channel unidirectional TVS structure optimized for low-capacitance transient suppression on data lines. Each channel features independent cathode-to-anode configuration with common cathode connection (pin 3), enabling bidirectional protection of two separate I/O paths using a single compact footprint.
It operates across -55 °C to +150 °C junction temperature range and meets AEC-Q101 qualification requirements when ordered with 'H' suffix - though VESD08A2-03G-G3-08 itself carries standard industrial-grade marking ('G3-08' packaging code, no 'H'), confirming non-automotive grade per ordering table.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 8 V - maximum continuous working voltage before leakage exceeds 0.1 μA; defines upper limit for protected signal swing. |
| Reverse Clamping Voltage | 13.7–15.3 V at 6.6 A - peak voltage seen by protected circuit during worst-case 8/20 μs surge; ensures downstream ICs remain below absolute max ratings. |
| Capacitance | 37–57 pF at 0 V, 1 MHz - low enough for USB 2.0 (480 Mbps) and HDMI 1.4 (up to 3.4 Gbps) without signal integrity degradation. |
| ESD Immunity | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - exceeds Level 4 system-level ESD requirements for consumer and industrial end equipment. |
| Peak Pulse Power | 100 W (8/20 μs) - sustains multiple high-energy transients without degradation; supports robust field reliability. |
| Dynamic Resistance | 0.23 Ω (TLP, 100 ns) - low impedance limits voltage overshoot during fast-rising ESD events (<1 ns rise time). |
Pinout & Package
SOT-323 package (3-pin, 2.2 mm × 1.35 mm × 0.95 mm), MSL level 1, peak reflow temperature 260 °C, UL 94 V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Channel 1 | Connects to first protected signal line; forward-biased during negative transients. |
| 2 | Anode of Channel 2 | Connects to second protected signal line; independent clamping path from Pin 1. |
| 3 | Common Cathode | Shared return path to ground or supply rail; enables compact dual-channel layout with single reference node. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line unidirectional protection | Two independent ESD paths share one cathode (Pin 3), reducing PCB area vs. discrete diodes while maintaining signal isolation. |
| Low dynamic resistance | 0.23 Ω enables rapid voltage clamping during sub-nanosecond ESD events, minimizing energy transfer to protected IC. |
| Sn (e3) lead finish | RoHS-compliant matte tin plating supports AOI-compatible solder joint inspection and eliminates lead-free reflow concerns. |
| Compact SOT-323 footprint | 2.2 mm × 1.35 mm outline allows placement directly at connector entry points without routing detours. |
Applications
| USB 2.0 Data Lines | HDMI DDC/CEC Channels |
|---|---|
Use Scenario: Protecting D+ and D- lines of USB 2.0 ports against ESD events during cable insertion or handling. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between connector and USB transceiver, with common cathode tied to system ground. Use Value: 37–57 pF capacitance avoids signal rise-time degradation at 480 Mbps; 13.7–15.3 V clamping prevents damage to PHY's 3.3 V I/O cells. | Use Scenario: Safeguarding HDMI DDC (I²C) and CEC control lines from user-induced ESD in home theater receivers and display panels. IC Role / Device Role / Timing Role: Dual-channel ESD suppressor mounted at HDMI receptacle, with Pins 1/2 on SDA/SCL or CEC, Pin 3 grounded. Use Value: 8 V standoff matches typical 3.3–5 V logic rails; ±30 kV ESD rating exceeds IEC 61000-4-2 Level 4 required for residential equipment. |
| Automotive Infotainment UART | Industrial RS-485 Transceiver I/O |
Use Scenario: Shielding UART lines (TX/RX) connecting head unit MCU to touch controller or Bluetooth module in vehicles. IC Role / Device Role / Timing Role: Signal-line protector located within 2 cm of connector, common cathode referenced to chassis ground. Use Value: -55 °C to +150 °C operating range supports under-dash environments; 100 W pulse power handles load-dump coupled transients. | Use Scenario: Adding secondary ESD protection on RS-485 A/B differential pair inputs in factory automation gateways. IC Role / Device Role / Timing Role: Low-capacitance shunt device placed before RS-485 receiver input, with Pin 3 connected to local ground plane. Use Value: 0.23 Ω dynamic resistance minimizes clamping delay; 6.6 A IPP rating complements primary MOV-based surge protection stages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J8.0A | Single-channel, SMA package (4.5 mm × 2.7 mm), 8.0 V standoff, 100 W, 600 W peak power | Requires two devices for dual-line protection; larger footprint; higher capacitance (~150 pF) | Use where board space permits discrete placement and higher surge margin is needed. |
| TPD2E001DRSR | 2-channel unidirectional, SOT-563, 5 V standoff, 12 V clamping, 12 pF capacitance | Lower voltage rating; optimized for 3.3 V systems; not suitable for 5 V or 8 V rails | Select only for low-voltage digital interfaces where VRWM ≤ 5 V is acceptable. |
Compared with SMA6J8.0A and TPD2E001DRSR, VESD08A2-03G-G3-08 uniquely balances dual-channel integration, 8 V standoff, and 37–57 pF capacitance in a 2.2 mm × 1.35 mm footprint - making it optimal for space-constrained 5–8 V data line protection where signal integrity and layout simplicity are critical.

FAQ
What is the maximum operating temperature for VESD08A2-03G-G3-08?
VESD08A2-03G-G3-08 has a junction temperature range of -55 °C to +150 °C, supporting operation in harsh environments including under-hood automotive locations and industrial enclosures. This rating is confirmed in the Absolute Maximum Ratings table for VESD08A2-03G on page 4 of Vishay document 86150 Rev. 1.4.
Does VESD08A2-03G-G3-08 meet AEC-Q101 qualification?
No, VESD08A2-03G-G3-08 does not carry AEC-Q101 qualification. The ordering table shows AEC-Q101 variants use an 'H' environmental code (e.g., VESD08A2-03GHG3A08), whereas VESD08A2-03G-G3-08 uses 'G3-08', indicating standard industrial-grade packaging without automotive qualification.
What is the reverse leakage current specification for VESD08A2-03G-G3-08 at 8 V?
At VR = 8 V, VESD08A2-03G-G3-08 exhibits a reverse current (IR) of 0.01–0.1 μA, as specified in the Electrical Characteristics table on page 5 of Vishay document 86150. This ultra-low leakage ensures minimal impact on high-impedance signal lines like I²C or UART.
Can VESD08A2-03G-G3-08 be used for bidirectional signal protection?
No, VESD08A2-03G-G3-08 is unidirectional. Its pin configuration (anodes on Pins 1/2, common cathode on Pin 3) clamps only negative transients on each line relative to ground. For bidirectional protection, a symmetric dual-diode array like VESD08A2-03D would be required - but that part is not in this family.
What is the recommended PCB footprint for VESD08A2-03G-G3-08?
The recommended SOT-323 footprint is provided in Figure 8 on page 8 of Vishay document 86150: pad length 1.15 mm, pad width 0.525 mm, pitch 1.35 mm, with thermal relief and solder mask defined. This matches JEDEC MO-203-AB standard and ensures reliable reflow yield at 260 °C peak temperature.
