Product details
Overview
VGSOT15C-G3-08 from Vishay Semiconductors is a two-line unidirectional ESD protection diode in SOT-23 package, featuring common-anode configuration, 15 V reverse stand-off voltage (VRWM), ±30 kV IEC 61000-4-2 ESD immunity, and 450 W peak pulse power (8/20 μs). It protects high-speed data lines such as USB 2.0 interfaces against electrostatic discharge.
For engineers reviewing the VGSOT15C-G3-08 datasheet, VGSOT15C-G3-08 pinout, VGSOT15C-G3-08 application, or VGSOT15C-G3-08 equivalent, key selection criteria include clamping voltage at rated surge current, line capacitance for signal integrity, AEC-Q101 qualification status, and dual-line BiAs-mode operation capability.
Technical Context
The VGSOT15C-G3-08 implements a dual-channel, common-anode ESD protection architecture supporting BiAs-mode (bidirectional asymmetrical) operation: pins 1 and 2 connect to protected signal lines, pin 3 to ground, enabling independent clamping of positive transients via reverse breakdown and negative transients via forward conduction. Its 15 V VRWM aligns with 12–15 V logic and interface rails.
In BiSy-mode (single-line bidirectional symmetrical), pins 1 and 2 form a differential pair with pin 3 left floating, delivering matched ±26.6 V clamping (at IPPM = 15.5 A) and 50–60 pF capacitance - optimized for balanced analog or low-capacitance serial buses requiring symmetrical transient suppression.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 15 V - maximum continuous reverse voltage before leakage exceeds 1 μA; sets upper limit for protected line operating voltage. |
| VBR (min) | 16.5 V - guaranteed reverse breakdown threshold at 1 mA; ensures reliable turn-on above normal operating range. |
| VC @ IPPM | 23.5–28.8 V - clamping voltage during 15.5 A 8/20 μs surge; defines worst-case overvoltage seen by downstream ICs. |
| CD @ 0 V | 100–120 pF - signal-line capacitance at zero bias; impacts high-frequency bandwidth and rise-time degradation on data lines. |
| PPPM (8/20 μs) | 450 W - peak pulse power handling; determines survivability against IEC 61000-4-5 lightning-induced surges. |
| ESD immunity | ±30 kV contact/air - meets IEC 61000-4-2 and ISO 10605; qualifies for industrial and automotive ESD robustness requirements. |
| TJ max. | +150 °C - maximum junction temperature; supports operation in under-hood or enclosed industrial environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J15A | Single-line, 15 V VRWM, 600 W PPPM (8/20 μs), 170 pF capacitance, DO-214AC package | Requires two devices for dual-line protection; higher capacitance limits high-speed data use | Select when higher surge rating is needed and board space allows discrete placement per line. |
| TPD2E001DRSR | Two-line, 5 V VRWM, 200 W PPPM, 12 pF capacitance, SOT-563 package, integrated ESD + EMI filter | Lower VRWM restricts use to 3.3 V systems; ultra-low capacitance suits USB 3.0/MIPI | Select for low-capacitance, high-speed interfaces where 15 V rating is unnecessary. |
Compared with SMA6J15A and TPD2E001DRSR, the VGSOT15C-G3-08 uniquely balances dual-line integration, 15 V VRWM compatibility with 12 V systems, and moderate 100–120 pF capacitance - making it optimal for cost-sensitive, space-constrained USB 2.0 and industrial data line protection where AEC-Q101 compliance is required.

FAQ
What is the maximum reverse working voltage (VRWM) of the VGSOT15C-G3-08?
The VGSOT15C-G3-08 has a maximum reverse working voltage (VRWM) of 15 V, verified per electrical characteristics table on page 7 of Vishay document 86325. This value represents the highest DC or continuous reverse voltage the device can block while maintaining leakage current ≤1 μA, making it suitable for protecting 12 V nominal signal lines such as automotive LIN or industrial control buses.
How does the VGSOT15C-G3-08 support dual-line ESD protection?
The VGSOT15C-G3-08 supports dual-line ESD protection via its common-anode BiAs-mode configuration: pins 1 and 2 connect to separate signal lines (e.g., USB D+ and D−), while pin 3 serves as the shared cathode tied to ground. During a positive ESD event on either line, the corresponding diode breaks down; during a negative event, both conduct forward - enabling independent, low-clamp protection without cross-talk.
Is the VGSOT15C-G3-08 qualified to AEC-Q101 standards?
Yes, the VGSOT15C-G3-08 is AEC-Q101 qualified, as confirmed in the "FEATURES" section (page 1) and "PACKAGE DATA" table (page 2) of Vishay document 86325. It meets human body model (HBM) Class H3B (>8 kV) and full stress testing per AEC-Q101 Rev D, ensuring reliability for automotive under-hood and cabin applications.
What is the clamping voltage of the VGSOT15C-G3-08 at its maximum peak pulse current?
At its maximum peak pulse current (IPPM = 15.5 A, 8/20 μs waveform), the VGSOT15C-G3-08 exhibits a reverse clamping voltage (VC) of 23.5–28.8 V, per the "ELECTRICAL CHARACTERISTICS VGSOT15C" table on page 7. This defines the upper bound of overvoltage imposed on protected circuitry during worst-case surge events.
Can the VGSOT15C-G3-08 be used in bidirectional symmetrical (BiSy) mode?
Yes, the VGSOT15C-G3-08 can operate in bidirectional symmetrical (BiSy) mode by connecting pins 1 and 2 across a single signal line (e.g., RS-485 A/B) and leaving pin 3 unconnected. In this configuration, it delivers matched ±26.6 V clamping at 15.5 A and 50–60 pF capacitance - ideal for balanced differential interfaces requiring equal positive/negative transient suppression.
