Product details
Overview
GSOT05C-G3-08 from Vishay Semiconductors is a two-line bidirectional ESD protection diode in SOT-23 package, rated for ±30 kV IEC 61000-4-2 contact/air discharge, 5 V max reverse working voltage (VRWM), and 30 A peak pulse current (IPPM) per line to ground. It serves as primary transient suppression for USB 2.0 data lines, HDMI hot-plug interfaces, and industrial sensor I/O.
For engineers reviewing the GSOT05C-G3-08 datasheet, GSOT05C-G3-08 pinout, GSOT05C-G3-08 application, or GSOT05C-G3-08 equivalent, key selection criteria include its BiAs-mode asymmetrical clamping (12 V VC at 30 A), 260 pF capacitance at 0 V, AEC-Q101 qualification option, and SOT-23 footprint compatibility with space-constrained PCB layouts.
Technical Context
The GSOT05C-G3-08 implements BiAs-MODE (Bidirectional Asymmetrical) protection: pins 1 and 2 connect to protected signal lines, pin 3 to ground, enabling independent clamping of positive transients (via reverse-biased diodes) and negative transients (via forward conduction). Its dual-diode structure delivers distinct clamping voltages-12 V reverse vs. 4.5 V forward-at 30 A IPPM.
It supports BiSy-MODE operation (single-line symmetrical protection) when pin 3 is left unconnected and pins 1–2 form the protected path, yielding 17 V clamping at 30 A with 130 pF capacitance. Both modes comply with IEC 61000-4-5 (8/20 μs) and AEC-Q101 H3B ESD class (>8 kV HBM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±30 kV contact/air discharge per IEC 61000-4-2 - ensures robust immunity against human-body and system-level ESD events. |
| Max Reverse Working Voltage | 5 V - compatible with 3.3 V and 5 V digital interfaces without leakage-induced signal distortion. |
| Peak Pulse Current (IPPM) | 30 A per line-to-ground path - handles high-energy surges from IEC 61000-4-5 8/20 μs waveforms. |
| Clamping Voltage (VC) | 12 V at 30 A (reverse), 4.5 V at 30 A (forward) - limits transient overvoltage to safe levels for downstream ICs. |
| Capacitance | 260 pF at 0 V, 150 pF at 2.5 V - balances ESD robustness and signal integrity for <100 Mbps data lines. |
| Operating Temperature | −55 °C to +150 °C - supports automotive under-hood and industrial control environments. |
| AEC-Q101 Qualified | Available in AEC-Q101-compliant variant - validated for automotive electronics reliability requirements. |
Pinout & Package
SOT-23 package (3-pin, standard leadframe, e3 Sn plating, MSL level 1, 8.8 mg weight, UL 94 V-0 molding compound).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Line 1 Anode / Cathode | Connects to first protected signal line (L1); forms one half of BiAs protection path to ground (pin 3). |
| Pin 2 | Line 2 Anode / Cathode | Connects to second protected signal line (L2); forms second half of BiAs protection path to ground (pin 3). |
| Pin 3 | Ground Reference | Must be connected to system ground for BiAs operation; left floating for BiSy single-line mode. |
Key Features
| Feature | Design Value |
|---|---|
| Two-line ESD protection | Simultaneous protection of differential or parallel signal pairs (e.g., USB D+/D−) with shared ground return. |
| BiAs-MODE asymmetry | Enables low forward-voltage clamping (4.5 V @ 30 A) for negative transients while maintaining higher reverse clamping (12 V @ 30 A) for positive surges. |
| Space-saving SOT-23 | Reduces PCB area by >50% versus discrete dual-diode solutions; compatible with automated SMT assembly. |
| e3 matte tin plating | RoHS-compliant, lead-free termination with proven solderability and intermetallic reliability. |
| MSL level 1 rating | Allows unlimited floor life and reflow at up to 260 °C peak - eliminates baking requirements for production. |
Applications
| USB 2.0 Interface Protection | HDMI Hot-Plug Detection |
|---|---|
Use Scenario: Protecting D+ and D− lines from ESD during cable insertion/removal in portable and embedded hosts.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VGSOT05C-G3-08 | Successor series with identical SOT-23 footprint, same 5 V VRWM and ±30 kV ESD rating, but improved 1000-cycle temperature cycling reliability. | Drop-in replacement for new designs; requires no layout change but offers extended product lifecycle beyond January 2025 EOL. | Select for long-term production continuity and enhanced thermal cycling endurance. |
| TPD2E001DRYR | Single-channel 2-line ESD protector with lower 12 pF capacitance but only ±8 kV IEC 61000-4-2 rating and no AEC-Q101 option. | Better suited for high-speed USB 3.0 or MIPI where capacitance is critical, but insufficient for automotive or industrial surge immunity. | Choose only for low-capacitance, non-automotive applications where ESD threat level is moderate. |
Compared with VGSOT05C-G3-08, the original GSOT05C-G3-08 offers identical electrical specs but lacks the successor's extended thermal cycling validation; versus TPD2E001DRYR, it trades higher capacitance for superior ESD robustness and automotive qualification-making it optimal for ruggedized interfaces.

FAQ
What is the maximum operating temperature range for the GSOT05C-G3-08?
The GSOT05C-G3-08 operates from −55 °C to +150 °C, making it suitable for under-hood automotive applications and industrial environments with wide ambient swings. This range is confirmed in the Absolute Maximum Ratings table for GSOT05C and applies directly to the GSOT05C-G3-08 variant.
Does the GSOT05C-G3-08 support both bidirectional asymmetrical and symmetrical protection modes?
Yes, the GSOT05C-G3-08 supports BiAs-MODE (pins 1 and 2 to signals, pin 3 to ground) for two-line asymmetrical clamping, and BiSy-MODE (pin 3 unconnected, pins 1–2 across one line) for single-line symmetrical clamping. Both configurations are fully documented in the GSOT05C datasheet section "BiAs-MODE" and "BiSy-MODE".
What is the clamping voltage of the GSOT05C-G3-08 at its full 30 A peak pulse current?
At 30 A peak pulse current (IPPM), the GSOT05C-G3-08 exhibits a reverse clamping voltage (VC) of 12 V maximum and a forward clamping voltage (VF) of 4.5 V maximum. These values are specified in the Electrical Characteristics table for GSOT05C under "Reverse clamping voltage" and "Forward clamping voltage" test conditions.
Is the GSOT05C-G3-08 qualified to AEC-Q101 standards?
The GSOT05C-G3-08 is offered in an AEC-Q101-qualified version (marked with "H" prefix, e.g., GSOT05C-HG3-08). The base GSOT05C-G3-08 variant is not AEC-Q101 qualified, but the datasheet confirms AEC-Q101 qualification is available for the GSOT05C family, and the ordering table lists HG3 and HE3 suffixes for that purpose.
What is the typical capacitance of the GSOT05C-G3-08 at 0 V bias and 1 MHz?
The GSOT05C-G3-08 has a typical capacitance of 260 pF at 0 V reverse bias and 1 MHz, with a maximum of 350 pF. This value is explicitly listed in the "ELECTRICAL CHARACTERISTICS GSOT05C" table under "Capacitance" with test condition "at VR = 0 V; f = 1 MHz".
