Product details
Overview
VGSOT08C-G3-08 from Vishay Semiconductors is a two-line unidirectional ESD protection diode in SOT-23 package, featuring common-anode dual-channel configuration, 8 V maximum reverse working voltage (VRWM), ±30 kV IEC 61000-4-2/ISO 10605 ESD immunity, and 500 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 VGSOT08C-G3-08 datasheet, VGSOT08C-G3-08 pinout, VGSOT08C-G3-08 application, or VGSOT08C-G3-08 equivalent, key selection considerations include its BiAs-mode asymmetrical clamping behavior, low 175–250 pF line capacitance at 0 V, 28 A peak pulse current capability, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
The VGSOT08C-G3-08 implements BiAs-MODE (Bidirectional Asymmetrical) protection: with pin 3 grounded and pins 1/2 connected to signal lines, it provides distinct forward clamping (~1.0–3.2 V) and reverse clamping (10.7–18.0 V at 28 A) for transient suppression. Its dual-diode common-anode topology enables independent line protection while sharing ground return path.
It supports BiSy-MODE (Bidirectional Symmetrical) operation when used as a single-line device (pins 1–2 only, pin 3 floating), delivering matched positive/negative clamping via series diode conduction - yielding 11.7–22.2 V clamping at 28 A with 87–125 pF capacitance. Both modes maintain ±30 kV ESD immunity per IEC 61000-4-2 and ISO 10605.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 8 V - Maximum continuous reverse voltage before leakage exceeds 5 μA; sets upper limit for protected signal swing in normal operation. |
| VBR (min) | 9 V - Minimum reverse breakdown voltage at 1 mA; ensures reliable turn-on during overvoltage events above system operating range. |
| VC @ 28 A (8/20 μs) | 14.4–18.0 V - Clamping voltage under full-rated surge; defines worst-case voltage seen by downstream IC during ESD strike. |
| CD @ 0 V / 1 MHz | 175–250 pF - Signal-line capacitance at zero bias; directly impacts high-speed data integrity (e.g., USB 2.0 eye diagram margin). |
| IPPM (8/20 μs) | 28 A - Peak pulse current handling capacity; determines survivability against IEC 61000-4-5 surge events. |
| ESD immunity | ±30 kV contact/air discharge - Complies with IEC 61000-4-2 and ISO 10605; qualifies for Level 4 system-level ESD robustness. |
| AEC-Q101 qualified | Yes - Validated for automotive applications including temperature cycling, HBM (>8 kV), and mechanical stress per AEC standard. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J8.0A | Single-line, unidirectional TVS; 8.0 V VRWM; 600 W PPPM (8/20 μs); SMC package (larger than SOT-23). | Requires two devices for dual-line protection; higher parasitic inductance due to larger package; no BiSy mode support. | Select when higher surge rating (600 W vs. 500 W) is prioritized over footprint and dual-line integration. |
| TPD2E001DRSR | Two-line, unidirectional ESD array; 5.5 V VRWM; 200 W PPPM; 15 pF CD @ 0 V; SON-6 package. | Lower clamping voltage (12 V @ 4 A) but significantly lower capacitance-optimized for USB 3.0/MIPI, not 8 V rail systems. | Select for high-speed interfaces requiring <20 pF loading; avoid where 8 V VRWM or AEC-Q101 qualification is mandatory. |
Compared with SMA6J8.0A and TPD2E001DRSR, the VGSOT08C-G3-08 uniquely balances 8 V standoff, dual-line integration in SOT-23, ±30 kV ESD rating, and automotive qualification-making it optimal for space-constrained, safety-critical dual-signal protection where moderate capacitance is acceptable.
