Product details
Overview
VESD08A2-03GHG3-08 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 delivers 13.7–15.3 V reverse clamping at full surge and 37–57 pF capacitance at 0 V bias, serving as primary transient suppression for USB 2.0 data lines in automotive infotainment systems.
For engineers reviewing the VESD08A2-03GHG3-08 datasheet, VESD08A2-03GHG3-08 pinout, VESD08A2-03GHG3-08 application, or VESD08A2-03GHG3-08 equivalent, key selection criteria include its 8 V working voltage, low 0.23 Ω dynamic resistance, 2-line protection architecture, and AEC-Q101 qualification status - all critical for high-reliability interface protection in harsh environments.
Technical Context
The VESD08A2-03GHG3-08 implements two independent unidirectional TVS diodes in a single SOT-323 package, with common cathode configuration (pins 1 & 2 anodes, pin 3 cathode). Its IEC 61000-4-2 compliance covers ±30 kV contact and air discharge, while IEC 61000-4-5 rating supports 6.6 A (8/20 μs) surge handling.
Designed for signal-line protection, it features low 37–57 pF capacitance to minimize signal integrity impact on high-speed interfaces, and a tight 9.5–10.5 V breakdown voltage (at 1 mA) ensuring precise triggering above 8 V operating rails. Thermal performance is validated across −55 °C to +150 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 8 V - maximum continuous DC or RMS signal voltage the device blocks without clamping, matching standard 5 V–8 V logic and interface rails. |
| Reverse Clamping Voltage | 13.7–15.3 V at 6.6 A (8/20 μs) - peak voltage seen by protected circuit during worst-case surge, ensuring downstream ICs remain below absolute max ratings. |
| Capacitance | 37–57 pF at 0 V, 1 MHz - low enough to avoid signal degradation on USB 2.0 (480 Mbps) and other high-speed digital lines. |
| ESD Immunity | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - exceeds Level 4 industrial and automotive ESD requirements for external ports. |
| Peak Pulse Current | 6.6 A (8/20 μs, IEC 61000-4-5) - sustains transient energy from lightning-induced surges or inductive switching events. |
| Dynamic Resistance | 0.23 Ω (TLP, 100 ns) - enables fast, low-voltage clamping response with minimal overshoot during nanosecond-scale transients. |
| Operating Temperature | −55 °C to +150 °C - supports under-hood and engine-control module deployment per AEC-Q101 stress testing. |
Pinout & Package
SOT-323 package (JEDEC TO-236AB), 3-terminal surface-mount plastic case with gull-wing leads; footprint compatible with IPC-7351B SOIC-3 recommendations, MSL level 1, peak reflow ≤ 260 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Channel 1 | Connects to first protected signal line (e.g., USB D+); conducts surge current to common cathode when voltage exceeds VRWM. |
| Pin 2 | Anode of Channel 2 | Connects to second protected signal line (e.g., USB D−); operates independently but shares cathode return path. |
| Pin 3 | Common Cathode | Return path for both channels; must be connected to system ground plane with low-inductance layout to ensure effective clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Dual unidirectional protection | Two independent anode-to-cathode paths enable separate clamping for differential pairs without cross-talk or shared failure modes. |
| AEC-Q101 qualified | Validated for automotive applications including powertrain, body electronics, and infotainment - includes HTOL, TC, and ESD stress screening. |
| Low dynamic resistance | 0.23 Ω ensures rapid voltage collapse during ESD events, minimizing time above safe logic thresholds and reducing risk of latch-up. |
| Sn (e3) lead plating | Tin termination enables compatibility with standard Pb-free reflow profiles and automated optical inspection (AOI) for solder joint verification. |
| MSL level 1 rating | Unlimited floor life at ≤30 °C/60% RH eliminates bake requirements before assembly, simplifying manufacturing logistics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD-protection diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J8.0A-Q | Single-channel, 8.0 V standoff, DO-214AC package, higher 100 W PPP but larger footprint and 100+ pF capacitance. | Not suitable for differential high-speed lines; better for power rail or single-ended I/O where space and capacitance are less constrained. | Select only if replacing discrete single-line protection and board area permits larger package. |
| TPD2E001DRYR | 2-channel, 5.5 V standoff, 0.5 pF typical capacitance, but rated only to ±8 kV ESD and not AEC-Q101 qualified. | Targeted at consumer USB ports; lacks automotive-grade reliability and surge robustness for under-hood or safety-critical systems. | Use only in non-automotive, low-risk environments where ultra-low capacitance outweighs ESD/surge margin requirements. |
Compared with SMA6J8.0A-Q and TPD2E001DRYR, the VESD08A2-03GHG3-08 uniquely balances 8 V standoff, ±30 kV ESD rating, AEC-Q101 qualification, and sub-60 pF capacitance in a compact SOT-323 - making it the only option among the three qualified for automotive USB 2.0 interface protection with production-grade reliability.

FAQ
What is the maximum continuous reverse voltage the VESD08A2-03GHG3-08 can block without clamping?
The VESD08A2-03GHG3-08 has a reverse standoff voltage (VRWM) of 8 V, meaning it blocks up to 8 V DC or RMS signal voltage continuously without entering conduction. This value is confirmed in the Electrical Characteristics table for VESD08A2-03G, where VRWM is specified as 8 V with no min/max tolerance - indicating a nominal rating strictly maintained across production lots. Exceeding this voltage risks premature leakage or breakdown.
Does the VESD08A2-03GHG3-08 meet automotive qualification standards?
Yes, the VESD08A2-03GHG3-08 is AEC-Q101 qualified, as explicitly stated in the Ordering Information section and supported by qualification test data referenced in Vishay's internal documentation. This certification covers stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and human-body-model (HBM) ESD - validating its suitability for automotive powertrain, body, and infotainment modules.
What is the clamping voltage of the VESD08A2-03GHG3-08 under full IEC 61000-4-5 surge conditions?
Under IEC 61000-4-5 8/20 μs surge conditions at its rated peak pulse current of 6.6 A, the VESD08A2-03GHG3-08 clamps to 13.7–15.3 V (typical to maximum), as specified in the Electrical Characteristics table. This clamping window ensures protected circuits remain within safe operating limits during transient events, with the upper bound guaranteeing worst-case voltage exposure.
How many signal lines does the VESD08A2-03GHG3-08 protect, and what is its channel configuration?
The VESD08A2-03GHG3-08 protects exactly two signal lines using a dual unidirectional configuration: Pin 1 serves as the anode for Channel 1, Pin 2 as the anode for Channel 2, and Pin 3 is their shared cathode. This structure is confirmed in the Absolute Maximum Ratings and Electrical Characteristics sections, which specify "2 lines" for Nchannel and define test conditions "between pin 1–3 or 2–3".
Is the VESD08A2-03GHG3-08 compatible with lead-free reflow soldering processes?
Yes, the VESD08A2-03GHG3-08 features Sn (e3) lead plating and is rated for peak reflow temperatures up to 260 °C, fully compliant with JEDEC J-STD-020 moisture sensitivity level 1 and RoHS-compliant Pb-free assembly requirements. The datasheet explicitly states "soldering can be checked by standard vision inspection" and confirms AOI compatibility due to the matte tin finish.
