Product details
Overview
GSOT05C-HG3-18 from Vishay Semiconductors is a two-line bidirectional asymmetrical 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 30 A peak pulse current (IEC 61000-4-5, 8/20 μs). It protects high-speed data lines such as USB 2.0 or HDMI interfaces against electrostatic discharge.
For engineers reviewing the GSOT05C-HG3-18 datasheet, GSOT05C-HG3-18 pinout, GSOT05C-HG3-18 application, or GSOT05C-HG3-18 equivalent, key selection criteria include clamping voltage at 30 A (≤16 V), low line capacitance (260–350 pF at 0 V), AEC-Q101 qualification status, and SOT-23 footprint compatibility with space-constrained PCB layouts.
Technical Context
The GSOT05C-HG3-18 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 asymmetry yields lower forward clamping (~4.5 V at 30 A) versus reverse clamping (~12 V at 30 A).
It supports dual-mode operation - BiAs-MODE for two-line protection and BiSy-MODE (pin 1–2 only, pin 3 open) for single-line symmetrical clamping with VRWM = 5.5 V and VC ≤ 20.4 V at 30 A - enabling flexible layout reuse across interface types.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Protection Type | Two-line bidirectional asymmetrical (BiAs-MODE); also configurable for single-line bidirectional symmetrical (BiSy-MODE) |
| Reverse Stand-off Voltage (VRWM) | 5 V - maximum continuous operating voltage before clamping activates on data lines |
| ESD Immunity | ±30 kV contact/air discharge per IEC 61000-4-2 - exceeds industrial and automotive ESD robustness requirements |
| Peak Pulse Current (IPPM) | 30 A (8/20 μs waveform) - handles severe surge events without failure |
| Clamping Voltage (VC) | 12 V max at 30 A (reverse), 4.5 V max at 30 A (forward) - limits transient overvoltage to safe levels for downstream ICs |
| Line Capacitance (CD) | 260–350 pF at 0 V, 150 pF at 2.5 V - preserves signal integrity on 480 Mbps USB 2.0 links |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including HBM >8 kV (Class H3B) |
Pinout & Package
SOT-23 package (JEDEC TO-236AB), 3-pin surface-mount, 2.8 × 2.35 × 1.15 mm body, e3 Sn plating, MSL Level 1, compatible with standard reflow profiles (peak 260 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Signal Line 1 Anode / Cathode | Connects to first protected data line (e.g., USB D+); forms one half of BiAs protection path to ground (pin 3) |
| Pin 2 | Signal Line 2 Anode / Cathode | Connects to second protected data line (e.g., USB D−); forms second half of BiAs protection path to ground (pin 3) |
| Pin 3 | Ground Terminal | Low-inductance connection to system ground plane; essential for effective transient shunting in BiAs-MODE |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Asymmetrical Clamping | Enables tighter negative-voltage control (VF ≤ 4.5 V @ 30 A) while maintaining robust positive-voltage suppression (VC ≤ 12 V @ 30 A) |
| Low Capacitance at Operating Bias | 150 pF at VR = 2.5 V - minimizes signal distortion on 5 V-tolerant high-speed interfaces |
| AEC-Q101 Qualification | Validated for automotive environments including temperature cycling, mechanical shock, and HBM ESD ≥ 8 kV |
| Parallelable Architecture | Two internal diodes allow parallel use to double IPPM (to 60 A) and halve effective clamping impedance |
| SOT-23 Footprint | Standardized 3-pin package enables drop-in replacement and automated assembly without redesign |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VGSOT05C-G3-18 | Direct successor in Vishay's next-generation VGSOTxxC series; identical VRWM (5 V), same SOT-23 package, improved thermal resistance (RθJA reduced by 12 %) | Same BiAs/BiSy modes and pinout; optimized for higher ambient temperature operation in enclosed enclosures | Select VGSOT05C-G3-18 for new designs targeting extended lifecycle beyond January 2025 EOL date of GSOT05C-HG3-18 |
| TPD2E001DRYR | TI device: 2-channel, 5.5 V VRWM, 12 pF typical capacitance at 0 V, ±15 kV ESD rating, no AEC-Q101 qualification | Lower capacitance suits >480 Mbps interfaces but lacks automotive qualification and fails IEC 61000-4-2 ±30 kV requirement | Choose TPD2E001DRYR only for cost-sensitive consumer applications where ±15 kV ESD suffices and AEC-Q101 is not required |
Compared with VGSOT05C-G3-18, GSOT05C-HG3-18 offers identical electrical protection specs but lacks the enhanced thermal performance needed for sustained high-power surge environments; versus TPD2E001DRYR, it delivers superior ESD immunity and automotive qualification at the expense of higher line capacitance.

Both configurations are fully documented in the "BiAs-MODE" and "BiSy-MODE" sections of the GSOT05C-HG3-18 datasheet.
What is the reverse leakage current specification for GSOT05C-HG3-18 at its rated VRWM?
