Product details
Overview
VGSOT05-G3-08 from Vishay Semiconductors is a unidirectional single-line ESD protection diode in SOT-23 package, rated for 5 V reverse stand-off voltage (VRWM), ±30 kV IEC 61000-4-2 ESD immunity, and 500 W peak pulse power (8/20 μs). It delivers 36 A peak pulse current and clamps transients to ≤14 V at full stress, serving as primary I/O line protection in USB 2.0, HDMI, and industrial sensor interfaces.
For engineers reviewing the VGSOT05-G3-08 datasheet, VGSOT05-G3-08 pinout, VGSOT05-G3-08 application, or VGSOT05-G3-08 equivalent, this page provides verified electrical specs, BiAs-mode clamping behavior, SOT-23 terminal mapping, automotive-grade AEC-Q101 qualification status, and direct alternative part comparisons with documented parameter trade-offs.
Technical Context
The VGSOT05-G3-08 implements Bidirectional Asymmetrical (BiAs) protection mode: pin 1 grounded, pin 3 connected to signal line; reverse conduction begins at 6–8 V breakdown (VBR), clamping positive transients to ≤14 V at 36 A, while forward conduction limits negative excursions to ≤3.9 V at same current. Its 279–350 pF capacitance at 0 V bias supports high-speed data lines up to ~200 Mbps without signal integrity degradation.
This device operates across –55 °C to +150 °C junction temperature, meets AEC-Q101 stress testing for automotive use, and features Sn (e3) matte tin terminations compatible with lead-free reflow per J-STD-020 MSL level 1 (peak 260 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5 V - Maximum continuous DC operating voltage before leakage exceeds 10 μA; sets upper limit for protected signal swing. |
| VBR (min/typ/max) | 6 / 6.8 / 8 V - Reverse breakdown threshold at 1 mA; defines onset of clamping for overvoltage events. |
| VC @ IPPM = 36 A | ≤14 V - Clamped voltage during worst-case 8/20 μs surge; determines maximum stress on downstream IC. |
| Capacitance @ 0 V | 279–350 pF - Signal-line loading at DC bias; impacts rise time and bandwidth in high-speed interfaces. |
| ESD immunity | ±30 kV contact/air (IEC 61000-4-2 & ISO 10605) - Guarantees robustness against human-body and system-level ESD events. |
| PPPM (8/20 μs) | 500 W - Peak transient energy absorption capability; enables protection against lightning-induced surges per IEC 61000-4-5. |
| TJ max. | +150 °C - Maximum junction temperature; supports operation in under-hood automotive and industrial environments. |
Pinout & Package
SOT-23 package: 3-pin, surface-mount, gull-wing leads; 2.9 mm × 1.3 mm × 1.01 mm body; 0.95 mm lead pitch; UL 94 V-0 molding compound; MSL level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Ground (Anode common) | Low-impedance return path for ESD current; must be connected to clean system ground plane with minimal inductance. |
| Pin 2 | No connection (NC) | Internally isolated; no electrical function; must remain unconnected on PCB. |
| Pin 3 | Protected line (Cathode) | Input/output signal terminal; clamps to ground during overvoltage; placed directly at connector or IC pad. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional BiAs clamping | Asymmetric response: 6–8 V reverse breakdown vs. ≤1.2 V forward conduction - minimizes ground bounce during negative ESD events. |
| AEC-Q101 qualified | Qualified per stress test requirements for automotive electronics - enables use in infotainment, ADAS, and body control modules. |
| e3 matte tin terminations | Lead (Pb)-free, RoHS-compliant Sn plating - ensures compatibility with Pb-free reflow profiles and eliminates whisker risk. |
| Low leakage at VRWM | ≤10 μA at 5 V - prevents signal distortion or power loss in battery-powered or high-impedance sensor circuits. |
| High ESD robustness | ±30 kV per IEC 61000-4-2 - exceeds Level 4 immunity requirement for industrial and medical equipment. |
Applications
| USB 2.0 Data Lines | HDMI TMDS Channels |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Higher VRWM (5.0 V), but bidirectional; 600 W PPPM; 600 pF capacitance at 0 V. | Less suitable for high-speed data lines due to higher capacitance; better for power rail or low-frequency analog protection. | Select when bidirectional clamping is required and signal bandwidth <10 MHz. |
| TPD2E001DRYR | Lower VRWM (5.5 V), dual-channel; 12 pF typical capacitance; ±8 kV HBM ESD rating only. | Optimized for USB 2.0 and DisplayPort; lacks ±30 kV system-level ESD rating and AEC-Q101 qualification. | Prefer for consumer portable devices where board space is critical and automotive qualification is unnecessary. |
Compared with SMAJ5.0A and TPD2E001DRYR, VGSOT05-G3-08 uniquely combines AEC-Q101 qualification, ±30 kV system-level ESD immunity, and sub-350 pF capacitance in a single-line unidirectional configuration-making it optimal for automotive and industrial high-speed serial interfaces requiring both robustness and signal fidelity.

FAQ
What is the exact reverse stand-off voltage (VRWM) of VGSOT05-G3-08?
The VGSOT05-G3-08 has a guaranteed maximum reverse stand-off voltage (VRWM) of 5 V, meaning it remains non-conductive with leakage ≤10 μA up to this DC voltage. This value is confirmed in the "ELECTRICAL CHARACTERISTICS VGSOT05" table on page 6 of Vishay document 86326, revision 1.1.
Does VGSOT05-G3-08 meet AEC-Q101 qualification requirements?
Yes, VGSOT05-G3-08 is explicitly AEC-Q101 qualified, as stated in the FEATURES section (page 1) and PACKAGE DATA table (page 2) of Vishay document 86326. This qualification covers temperature cycling, humidity bias, and ESD stress tests required for automotive electronics.
What is the pin configuration and function of VGSOT05-G3-08?
VGSOT05-G3-08 uses a standard SOT-23 package with three terminals: Pin 1 is ground (anode), Pin 2 is no-connect (NC), and Pin 3 is the protected signal line (cathode). This layout is defined in the BiAs-MODE description on page 5 and confirmed by the SOT-23 footprint recommendation on page 10.
How does the BiAs-mode clamping behavior of VGSOT05-G3-08 differ from standard TVS diodes?
VGSOT05-G3-08 employs Bidirectional Asymmetrical (BiAs) clamping: it conducts strongly in forward direction (VF ≤1.2 V) for negative transients, while breaking down at 6–8 V in reverse for positive transients. This asymmetry reduces ground bounce and avoids false triggering on bidirectional buses-unlike symmetrical TVS diodes that clamp equally in both directions.
What is the maximum clamping voltage (VC) of VGSOT05-G3-08 under full-rated surge current?
Under an 8/20 μs surge current of 36 A (IPPM), the VGSOT05-G3-08 clamps to a maximum of 14 V, as specified in the "ELECTRICAL CHARACTERISTICS VGSOT05" table (page 6, VC row, "At IPP = IPPM = 36 A" column). This value ensures downstream ICs see limited overvoltage stress during worst-case transients.
