Product details
Overview
VGSOT05C-G3-08 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-G3-08 datasheet, VGSOT05C-G3-08 pinout, VGSOT05C-G3-08 application, or VGSOT05C-G3-08 equivalent, key selection considerations include its BiAs-mode asymmetrical clamping behavior, low 276 pF line capacitance at 0 V, AEC-Q101 qualification, and compatibility with automated SMT assembly on 7" tape reels.
Technical Context
The VGSOT05C-G3-08 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 transients are suppressed at ~11 V (IPPM = 36 A), while forward transients clamp near 0 V via low VF (~3.9 V at 36 A).
When reconfigured in BiSy-MODE (Pin 3 floating, Pin 1–Pin 2 across signal line), it functions as a single-line bidirectional protector with 5.5 V VRWM and 17 V clamping at 36 A - leveraging matched breakdown and forward conduction for symmetrical transient suppression.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Device Type | Two-line unidirectional ESD protection diode (common anode) |
| VRWM | 5 V - defines maximum continuous operating voltage before leakage exceeds 10 μA; sets safe margin for 3.3 V logic interfaces |
| VBR (min) | 6 V - ensures reliable turn-on above normal signal swing; guarantees clamping activation during overvoltage events |
| VC @ IPPM | 11 V (max) at 36 A, 8/20 μs - limits voltage seen by protected ICs during surge; critical for 5 V tolerant I/O survival |
| CD @ 0 V | 276 pF (typ) - low enough for USB 2.0 (480 Mbps) and HDMI 1.4 signal integrity without excessive rise-time degradation |
| ESD Immunity | ±30 kV contact/air per IEC 61000-4-2 and ISO 10605 - exceeds Level 4 system-level ESD requirements for industrial and automotive ports |
| AEC-Q101 Qualified | Yes - validated for automotive under-hood and infotainment applications requiring robustness to temperature cycling and humidity |
Pinout & Package
SOT-23 package (JEDEC TO-236AB), 3-pin, surface-mount, green molding compound, MSL level 1, 260 °C peak reflow compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Connects to first protected signal line (L1); forms one clamping path to ground when Pin 3 is grounded |
| Pin 2 | Anode of Diode 2 | Connects to second protected signal line (L2); shares common cathode (Pin 3) for dual-line protection |
| Pin 3 | Common Cathode | Must be connected to system ground; provides return path for both ESD current paths in BiAs-MODE |
Key Features
| Feature | Design Value |
|---|---|
| BiAs-MODE asymmetrical clamping | Enables dual-line protection with low forward-voltage clamping (<4 V) for negative transients and controlled reverse clamping (~11 V) for positive surges |
| BiSy-MODE reconfigurability | Supports single-line bidirectional protection (Pin 3 open) with 5.5 V VRWM and symmetrical clamping - no redesign needed for alternate use cases |
| Low line capacitance | 276 pF typical at 0 V enables use on 480 Mbps USB 2.0 and other high-speed digital interfaces without signal distortion |
| AEC-Q101 qualification | Validated for automotive environments including temperature cycling (-55 °C to +150 °C junction), ensuring reliability in harsh conditions |
| e3 Sn terminations | Lead-free, RoHS-compliant matte tin plating ensures solderability and long-term intermetallic stability in automated assembly |
Applications
| USB 2.0 Interface Protection | HDMI 1.4 DDC/CEC Line Protection |
|---|---|
Use Scenario: Protecting differential D+ and D− lines of a USB 2.0 host port against user-handling ESD events. IC Role / Device Role / Timing Role: Dual-channel unidirectional TVS diode providing low-capacitance, common-cathode clamping to ground. Use Value: Maintains signal integrity (276 pF) while limiting clamped voltage to ≤11 V during 36 A surges - preserving USB PHY compliance. |
Use Scenario: Safeguarding HDMI 1.4 DDC (I²C) and CEC control lines from hot-plug and cable-discharge transients. IC Role / Device Role / Timing Role: Two-line ESD suppressor placed between source and sink on bidirectional 5 V control bus.

Use Value: AEC-Q101 qualification and 150 °C TJ max ensure operation across automotive temperature range without derating. |
Use Scenario: Protecting RS-485 transceiver A/B lines in factory automation gateways exposed to field wiring ESD and lightning-induced surges. IC Role / Device Role / Timing Role: Unidirectional ESD clamp with 5 V VRWM aligned to transceiver common-mode range. Use Value: 500 W peak pulse power (8/20 μs) handles repetitive surge stress better than standard 200 W TVS arrays. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J5.0A | Single-line, unidirectional, DO-214AC package; 5.0 V VRWM, 600 W PPPM, 400 pF capacitance | Requires two devices for dual-line protection; higher capacitance limits USB 2.0 use | Select when board space allows discrete placement and lower-cost DO-214AC is preferred over SOT-23 integration |
| TPD2E001DRSR | Two-line, unidirectional, SOT-23; 5.5 V VRWM, 350 W PPPM, 15 pF capacitance, integrated ESD protection only (no surge rating) | Optimized for low-capacitance high-speed interfaces but lacks IEC 61000-4-5 surge capability | Select for pure ESD-only scenarios (e.g., touch panel I²C) where 350 W surge rating is insufficient |
Compared with SMA6J5.0A and TPD2E001DRSR, the VGSOT05C-G3-08 uniquely combines dual-line SOT-23 integration, 500 W surge rating, ±30 kV ESD immunity, and AEC-Q101 qualification - making it optimal for space-constrained automotive and industrial data links requiring both ESD and surge resilience.

FAQ
What is the maximum reverse working voltage (VRWM) of the VGSOT05C-G3-08?
The VGSOT05C-G3-08 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 without significant leakage, making it suitable for protecting 3.3 V and 5 V logic interfaces while maintaining margin against normal signal swings. The VRWM is confirmed in the "ELECTRICAL CHARACTERISTICS VGSOT05C" table on page 6 of Vishay document 86325.
How does the VGSOT05C-G3-08 support dual-line ESD protection?
The VGSOT05C-G3-08 supports dual-line ESD protection using its common-anode BiAs-MODE configuration: Pin 1 and Pin 2 connect to two separate signal lines (e.g., USB D+ and D−), while Pin 3 is tied to ground. Each anode-to-cathode path clamps transients independently, delivering asymmetrical clamping - low forward-voltage suppression for negative events and controlled reverse breakdown for positive surges - all within a single SOT-23 footprint.
Is the VGSOT05C-G3-08 qualified for automotive applications?
Yes, the VGSOT05C-G3-08 is AEC-Q101 qualified, as explicitly stated in the "FEATURES" section and "PACKAGE DATA" table of Vishay document 86325. It meets stress test requirements for temperature cycling, humidity, mechanical shock, and ESD robustness required for automotive electronics, with a junction temperature range of −55 °C to +150 °C and MSL level 1 moisture sensitivity rating.
What is the typical line capacitance of the VGSOT05C-G3-08 at 0 V bias?
The typical line capacitance (CD) of the VGSOT05C-G3-08 is 276 pF at 0 V reverse bias and 1 MHz, per the "ELECTRICAL CHARACTERISTICS VGSOT05C" table on page 6 of Vishay document 86325. This low capacitance enables use on high-speed interfaces like USB 2.0 without degrading signal edge rates or causing impedance mismatch issues.
Can the VGSOT05C-G3-08 be used in bidirectional protection mode?
Yes, the VGSOT05C-G3-08 can be configured for bidirectional protection (BiSy-MODE) by leaving Pin 3 unconnected and using Pins 1 and 2 across a single signal line. In this mode, it delivers symmetrical clamping with 5.5 V VRWM and 17 V clamping voltage at 36 A (8/20 μs), as documented on page 10 of Vishay document 86325 - ideal for I²C, SMBus, or other bidirectional buses.
