Product details
Overview
VGSOT03C-HG3-08 from Vishay Semiconductors is a two-line unidirectional ESD protection diode in SOT-23 package, featuring common-anode dual-channel configuration, 3.3 V reverse stand-off voltage (VRWM), ±30 kV IEC 61000-4-2/ISO 10605 ESD immunity, and 540 W peak pulse power (8/20 μs). It protects high-speed data lines such as USB 2.0 or I²C interfaces against electrostatic discharge.
For engineers reviewing the VGSOT03C-HG3-08 datasheet, VGSOT03C-HG3-08 pinout, VGSOT03C-HG3-08 application, or VGSOT03C-HG3-08 equivalent, key selection considerations include its BiAs-mode asymmetrical clamping behavior, low 1.2 V forward clamping at 1 A, 460–600 pF capacitance at 0 V bias, and AEC-Q101 qualification for automotive signal line protection.
Technical Context
The VGSOT03C-HG3-08 implements a dual-diode common-anode topology enabling two-line unidirectional protection with independent clamping paths to ground (Pin 3). Its BiAs-MODE operation delivers asymmetrical clamping: reverse breakdown at 4.0–5.5 V (VBR) with 9.2–12.3 V clamping at 44 A, and forward conduction at ≤1.2 V (VF) for negative transients.
When reconfigured in BiSy-MODE (Pin 3 floating, Pin 1–Pin 2 across one line), it provides symmetrical bidirectional protection with 3.8 V VRWM and 7–8.4 V clamping at 1 A - optimized for single-line applications requiring matched positive/negative transient suppression.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Device Type | Two-line unidirectional ESD protection diode, common-anode dual-channel |
| VRWM | 3.3 V - maximum continuous reverse working voltage before leakage exceeds 100 μA; sets upper limit for protected signal swing |
| VBR (min/typ/max) | 4.0 / 4.6 / 5.5 V at 1 mA - defines onset of reverse conduction; determines minimum clamping threshold |
| VC @ IPPM = 44 A | 9.2–12.3 V (8/20 μs) - actual voltage seen by protected IC during worst-case surge; critical for downstream IC survival |
| Capacitance (CD) | 460–600 pF at 0 V, 320 pF at 1.6 V - directly impacts signal integrity on high-speed lines like USB 2.0 (480 Mbps) |
| ESD Immunity | ±30 kV contact/air discharge per IEC 61000-4-2 and ISO 10605 - meets Level 4 system-level ESD robustness requirements |

Pinout & Package
SOT-23 package (JEDEC TO-236AB), 3-pin, green molding compound, MSL level 1, 9.2 mg weight, UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Channel 1 | Connects to first protected signal line (L1); conducts negative transients to ground via Pin 3 |
| Pin 2 | Anode of Channel 2 | Connects to second protected signal line (L2); conducts negative transients to ground via Pin 3 |
| Pin 3 | Common Cathode | Must be connected to system ground; provides return path for both channels' clamping current |
Key Features
| Feature | Design Value |
|---|---|
| BiAs-MODE asymmetrical clamping | Enables separate optimization for positive (reverse-biased) and negative (forward-biased) transients - reduces forward clamping to ≤1.2 V while maintaining 4.0+ V reverse standoff |
| Dual-channel common-anode architecture | Protects two independent data lines (e.g., D+ and D−) with single device and shared ground connection - saves PCB area and routing complexity |
| Parallel operation capability | Two internal diodes can be paralleled (e.g., L1 + L2 tied) to double IPPM to 88 A and halve effective series inductance - lowers clamping voltage under extreme surges |
| AEC-Q101 qualification | Validated for automotive environments including temperature cycling (-55 °C to +150 °C junction), humidity, and mechanical stress - suitable for ADAS sensor interfaces |
| e3 Sn terminations | Lead (Pb)-free, RoHS-compliant matte tin plating - ensures solderability and long-term reliability without lead-based contamination risks |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD9X3.3SFT5G | Single-line unidirectional diode, 3.3 V VRWM, 150 pF capacitance, 300 W PPPM (8/20 μs) | Requires two devices for dual-line protection; lower capacitance suits >100 Mbps interfaces but lacks integrated dual-channel layout efficiency | Select when minimizing line capacitance is prioritized over board space and ground routing simplicity |
| TPD2E001DRYR | Dual-line unidirectional diode, 3.3 V VRWM, 12 pF capacitance, 200 W PPPM (8/20 μs), integrated 10 Ω series resistors | Lower capacitance enables USB 3.0 compatibility; reduced surge rating limits use to consumer-grade ESD levels (±15 kV) | Select for high-speed digital interfaces where ultra-low capacitance outweighs automotive-grade surge margin |
Compared with ESD9X3.3SFT5G and TPD2E001DRYR, the VGSOT03C-HG3-08 offers higher surge robustness (540 W vs. 300 W/200 W) and integrated dual-channel layout, making it optimal for space-constrained automotive and industrial designs requiring full ±30 kV compliance without external components.

FAQ
What is the maximum reverse working voltage (VRWM) of the VGSOT03C-HG3-08?
The VGSOT03C-HG3-08 has a maximum reverse working voltage (VRWM) of 3.3 V, verified at IR ≤ 100 μA. This value defines the highest continuous DC or peak AC voltage the device can withstand in reverse bias without significant leakage, making it suitable for 3.3 V logic and interface circuits. The VGSOT03C-HG3-08 maintains this rating across its full operating temperature range of -55 °C to +150 °C.
How does the VGSOT03C-HG3-08 achieve asymmetrical clamping behavior?
The VGSOT03C-HG3-08 achieves asymmetrical clamping (BiAs-MODE) via its common-anode dual-diode structure: positive transients trigger reverse breakdown (VBR = 4.0–5.5 V) with clamping up to 12.3 V at 44 A, while negative transients conduct in forward bias with VF ≤ 1.2 V. This design minimizes forward clamping voltage without compromising reverse standoff - a key advantage over symmetrical TVS diodes. The VGSOT03C-HG3-08 leverages this for precise protection of bidirectional data lines.
Can the VGSOT03C-HG3-08 be used for single-line bidirectional protection?
Yes - the VGSOT03C-HG3-08 supports BiSy-MODE operation for single-line bidirectional protection by leaving Pin 3 unconnected and using Pins 1 and 2 across one signal line. In this configuration, it delivers 3.8 V VRWM, 4.5–6.2 V VBR, and 7–8.4 V clamping at 1 A. This mode provides matched positive/negative clamping essential for RS-485 or CAN physical layers. The VGSOT03C-HG3-08 retains full ±30 kV ESD immunity in BiSy-MODE.
What is the peak pulse power rating of the VGSOT03C-HG3-08 under IEC 61000-4-5 conditions?
The VGSOT03C-HG3-08 is rated for 540 W peak pulse power (PPP) under IEC 61000-4-5 8/20 μs waveform conditions, measured at IPPM = 44 A. This rating reflects its ability to absorb high-energy surges such as those induced by lightning or inductive switching in automotive and industrial systems. The VGSOT03C-HG3-08 also sustains 44 W under the longer 10/1000 μs waveform, confirming thermal robustness for repetitive transients.
Is the VGSOT03C-HG3-08 qualified to AEC-Q101 standards?
Yes, the VGSOT03C-HG3-08 is AEC-Q101 qualified, specifically meeting the H3B human-body-model (HBM) class with >8 kV ESD tolerance. It undergoes rigorous stress testing including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing (uHAST) to ensure reliability in automotive under-hood and cabin applications. The VGSOT03C-HG3-08 carries Vishay's official AEC-Q101 certification for the full VGSOTxxC family.
