Product details
Overview
VGSOT05C-HG3-08 from Vishay Semiconductors is a two-line unidirectional ESD protection diode in SOT-23 package, featuring common-anode dual-channel configuration, 5 V maximum reverse working voltage (VRWM), ±30 kV IEC 61000-4-2 ESD immunity, and 500 W peak pulse power (8/20 μs). It protects high-speed data lines such as USB 2.0 and HDMI interfaces against electrostatic discharge.
For engineers reviewing the VGSOT05C-HG3-08 datasheet, VGSOT05C-HG3-08 pinout, VGSOT05C-HG3-08 application, or VGSOT05C-HG3-08 equivalent, this device supports BiAs-mode (bidirectional asymmetrical) and BiSy-mode (bidirectional symmetrical) configurations, offers low clamping voltage (11 V at 36 A), and enables design flexibility for dual-line or single-line transient suppression in automotive infotainment and industrial communication systems.
Technical Context
The VGSOT05C-HG3-08 implements a dual-diode common-anode structure enabling two independent signal-line protection paths with shared ground connection (Pin 3). Its BiAs-mode operation provides asymmetric clamping: forward conduction (VF ≈ 1.0–3.9 V) for negative transients and reverse breakdown (VBR = 6–8 V) for positive transients, yielding distinct clamping voltages per polarity.
In BiSy-mode, Pins 1 and 2 form a bidirectional symmetrical clamp with Pin 3 left floating; clamping relies on series conduction of one diode in forward bias and another in reverse breakdown, resulting in higher VC (17 V at 36 A) and reduced capacitance (138–175 pF at 0 V). Both modes comply with AEC-Q101 Class H3B (>8 kV HBM) and operate from –55 °C to +150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5 V - Maximum continuous reverse voltage before leakage exceeds 10 μA; defines safe operating range for protected 5 V logic/data lines. |
| VBR (min/typ/max) | 6 / 6.8 / 8 V at 1 mA - Reverse breakdown threshold; determines earliest activation point for positive ESD events. |
| VC @ IPPM | 11 V max at 36 A, 8/20 μs - Peak clamping voltage during worst-case surge; limits stress on downstream ICs. |
| CD @ 0 V | 276–350 pF - Junction capacitance at zero bias; impacts signal integrity in high-speed interfaces like USB 2.0. |
| ESD immunity | ±30 kV contact/air per IEC 61000-4-2 and ISO 10605 - Validated robustness against real-world human-body and system-level ESD events. |
| PPPM (8/20 μs) | 500 W - Peak pulse power handling capability; supports transient energy absorption without failure. |
| TJ max | +150 °C - Maximum junction temperature; enables use in under-hood automotive and industrial environments. |
Pinout & Package
SOT-23 package (JEDEC TO-236AB), 3-pin surface-mount, green molding compound, MSL level 1, 9.2 mg weight, UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5V3U2U-2/TR | Single-channel, 5.3 V VRWM, 350 W PPPM (8/20 μs), SOT-23-3, 120 pF @ 0 V | Lower capacitance but requires two devices for dual-line protection; no BiSy-mode capability | Select when ultra-low capacitance (<120 pF) is critical for >1 Gbps interfaces and board space allows dual placement. |
| TPD2EUSB30DRYR | Two-channel, 5.5 V VRWM, 3-A IEC 61000-4-2 rated, 0.9-pF typical CD, DSBGA-6 package | Far lower capacitance optimized for USB 3.0/3.1; not AEC-Q101 qualified; different footprint | Prefer for high-speed serial links where sub-1-pF loading is mandatory; avoid in automotive or high-temp industrial use. |
Compared with ESD5V3U2U-2/TR and TPD2EUSB30DRYR, the VGSOT05C-HG3-08 delivers higher surge robustness (500 W vs. ≤350 W), AEC-Q101 qualification, and dual operational modes-making it optimal for cost-sensitive, thermally demanding dual-line protection where moderate capacitance is acceptable.

FAQ
What is the maximum reverse working voltage (VRWM) of the VGSOT05C-HG3-08?
The VGSOT05C-HG3-08 has a maximum reverse working voltage (VRWM) of 5 V, specified at IR ≤ 10 μA. This value defines the highest continuous DC or peak AC voltage the device can withstand in reverse bias without exceeding rated leakage, making it suitable for protecting 5 V logic and data lines such as USB 2.0 and CAN FD interfaces. The VGSOT05C-HG3-08 maintains this rating across its full operating temperature range of –55 °C to +150 °C.
How does the VGSOT05C-HG3-08 support both BiAs-mode and BiSy-mode configurations?
The VGSOT05C-HG3-08 supports BiAs-mode (bidirectional asymmetrical) with Pin 3 grounded and Pins 1/2 connected to separate signal lines-enabling polarity-dependent clamping. For BiSy-mode (bidirectional symmetrical), Pin 3 is left unconnected and protection is implemented between Pins 1 and 2 only. This dual-mode capability is intrinsic to the common-anode dual-diode structure and is validated in the official Vishay datasheet for VGSOT05C-HG3-08.
Is the VGSOT05C-HG3-08 qualified to AEC-Q101 standards?
Yes, the VGSOT05C-HG3-08 is AEC-Q101 qualified and rated for Class H3B human-body model (HBM) with >8 kV ESD immunity. This qualification is explicitly stated in the Vishay document 86325 (Rev. 1.1) and confirmed by test reports covering temperature cycling, humidity testing, and mechanical shock-all required for automotive-grade component deployment. The VGSOT05C-HG3-08 meets these requirements in its standard SOT-23 package.
What is the peak clamping voltage (VC) of the VGSOT05C-HG3-08 under full surge conditions?
Under an 8/20 μs surge current of 36 A (IPPM), the VGSOT05C-HG3-08 exhibits a maximum peak clamping voltage (VC) of 14 V in BiAs-mode. At lower currents (e.g., 1 A), VC is 7.3–8.7 V. These values are measured per IEC 61000-4-5 and reflect the combined effect of diode breakdown voltage, series impedance, and thermal response. The VGSOT05C-HG3-08's clamping performance is guaranteed across its full operating temperature range.
Can the VGSOT05C-HG3-08 be used for single-line protection, and what are the trade-offs?
Yes, the VGSOT05C-HG3-08 supports single-line protection in BiSy-mode by connecting Pins 1 and 2 across the signal line and leaving Pin 3 unconnected. In this configuration, VRWM increases to 5.5 V and capacitance drops to 138–175 pF at 0 V, but peak clamping rises to 20.4 V at 36 A due to series diode conduction. This mode sacrifices some surge robustness for symmetrical bipolar response-ideal for RS-485 or legacy analog lines where polarity neutrality is essential. The VGSOT05C-HG3-08's datasheet fully specifies both operational modes.
