Product details
Overview
GSOT05C-HG3-08 from Vishay Semiconductors is a two-line bidirectional asymmetrical ESD protection diode in SOT-23 package, rated for ±30 kV IEC 61000-4-2 contact/air discharge, 5 V reverse stand-off voltage (VRWM), and 30 A peak pulse current (IPPM) per line to ground. It delivers 12 V max clamping voltage at 30 A in BiAs mode and supports automotive-grade transient suppression in USB 2.0, HDMI, and industrial I/O interfaces.
For engineers reviewing the GSOT05C-HG3-08 datasheet, GSOT05C-HG3-08 pinout, GSOT05C-HG3-08 application, or GSOT05C-HG3-08 equivalent, key selection criteria include its 260–350 pF capacitance at 0 V, 10 μA max reverse leakage at 5 V, AEC-Q101 qualification, RoHS-compliant green e3 Sn plating, and dual-mode operation (BiAs/BiSy) enabling flexible signal-line protection architecture.
Technical Context
The GSOT05C-HG3-08 implements BiAs-MODE (Bidirectional Asymmetrical) protection: pins 1 and 2 connect to protected lines, pin 3 to ground, delivering different forward (≤4.5 V) and reverse (≤16 V) clamping voltages. Its internal dual-diode structure enables independent transient shunting per line with shared ground reference.
In BiSy-MODE (single-line symmetrical), pin 3 is left unconnected, and pins 1–2 form a bipolar clamp with matched positive/negative clamping-achieving 17 V max VC at 30 A and 130–175 pF capacitance-suited for balanced differential buses like RS-485 or CAN FD physical layer protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±30 kV contact/air discharge per IEC 61000-4-2 - meets highest system-level ESD immunity requirements for consumer and automotive ports. |
| Reverse Stand-off Voltage (VRWM) | 5 V - ensures no conduction during normal 5 V logic or USB data signaling, preserving signal integrity. |
| Peak Pulse Current (IPPM) | 30 A per line-to-ground path - handles severe lightning-induced surges per IEC 61000-4-5 (8/20 μs). |
| Clamping Voltage (VC) | 12 V max at 30 A (BiAs mode) - limits transient overvoltage to safe levels for 5 V-tolerant ICs like microcontrollers and PHYs. |
| Capacitance (CD) | 260–350 pF at 0 V, 150 pF at 2.5 V - optimized for high-speed data lines up to 480 Mbps (USB 2.0 full-speed). |
| Operating Temperature | −55 °C to +150 °C - supports under-hood automotive, industrial control, and extended-temperature embedded applications. |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test standard, 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 matte tin (Sn) plating, MSL Level 1, peak reflow ≤260 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Line 1 Anode / Cathode (BiAs) | Connects to first protected signal line (e.g., USB D+); forms one half of dual-diode ESD path to ground (pin 3). |
| Pin 2 | Line 2 Anode / Cathode (BiAs) | Connects to second protected signal line (e.g., USB D−); forms second half of dual-diode ESD path to ground (pin 3). |
| Pin 3 | Ground Reference Terminal | Must be connected to low-impedance system ground; serves as common return for both ESD current paths in BiAs mode. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-mode protection (BiAs/BiSy) | Enables either two-line asymmetric (BiAs) or single-line symmetric (BiSy) configuration without redesign - reduces BOM count and layout flexibility. |
| Low clamping voltage asymmetry | Forward VF ≤4.5 V and reverse VC ≤16 V at 30 A - minimizes voltage overshoot on both polarities while maintaining low forward drop for negative transients. |
| Automotive-grade reliability | AEC-Q101 qualified with HBM >8 kV and operating range −55 °C to +150 °C - suitable for ADAS camera links and infotainment USB ports. |
| Controlled capacitance profile | Capacitance drops from 350 pF @ 0 V to 150 pF @ 2.5 V - preserves signal rise time and eye diagram margin on 480 Mbps USB 2.0 data lanes. |
| Green RoHS-compliant packaging | e3 Sn plating, halogen-free molding compound, UL 94 V-0 flammability - meets global environmental compliance and safety standards. |
Applications
| USB 2.0 Interface Protection | HDMI Data Lane Protection |
|---|---|

Use Scenario: Transient suppression on RS-485 A/B bus lines in factory automation PLC I/O modules. IC Role / Device Role / Timing Role: BiSy-mode configuration (pin 3 floating) across A–B differential pair for symmetrical surge clamping. Use Value: Delivers matched ±17 V clamping at 30 A and 130 pF capacitance - prevents false triggering and maintains DC common-mode range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VGSOT05C-HG3-08 | Direct successor family; same SOT-23 footprint, identical VRWM (5 V), improved leakage (<5 μA at 5 V), lower capacitance (220–300 pF). | End-of-life replacement with enhanced parametric performance; requires no PCB change. | Select for new designs requiring extended lifecycle support beyond January 2025 and tighter leakage/capacitance specs. |
| TPD2E001DRYR | Single-channel, 2-pin SOT-5X3; 5.5 V VRWM; 12 V VC at 1 A; 12 pF typical capacitance - much lower CD but no dual-line integration. | Requires two devices for dual-line protection; better for ultra-high-speed (>1 Gbps) interfaces where <15 pF is mandatory. | Choose when minimizing capacitance is critical and board space allows discrete placement per line. |
Compared with GSOT05C-HG3-08, VGSOT05C-HG3-08 offers longer product availability and tighter electrical tolerances, while TPD2E001DRYR trades integrated dual-line functionality for ultra-low capacitance-making it suitable only where per-line optimization outweighs component count and layout simplicity.

The maximum clamping voltage of GSOT05C-HG3-08 is 16 V at 30 A peak pulse current in BiAs mode (pin 1 or 2 to pin 3), measured per IEC 61000-4-5 8/20 μs waveform. This value ensures safe voltage limiting for 5 V logic interfaces while maintaining robust surge handling capability.
Can GSOT05C-HG3-08 be used for single-line symmetrical protection?
Yes, GSOT05C-HG3-08 supports BiSy-MODE: leave pin 3 unconnected and use pins 1 and 2 as a bidirectional clamp across a single differential or single-ended line. In this configuration, it delivers matched ±17 V clamping at 30 A and 130–175 pF capacitance, ideal for RS-485 or CAN FD bus protection.
Is GSOT05C-HG3-08 qualified for automotive applications?
Yes, GSOT05C-HG3-08 is AEC-Q101 qualified and rated for operation from −55 °C to +150 °C. It meets human body model (HBM) Class H3B (>8 kV) and passes all required stress tests, making it suitable for automotive infotainment, ADAS camera links, and body control modules.
What is the reverse leakage current specification for GSOT05C-HG3-08 at 5 V?
The reverse leakage current of GSOT05C-HG3-08 is specified at ≤10 μA when biased at its maximum reverse working voltage of 5 V (VR = 5 V), ensuring minimal DC loading on protected signal lines during normal operation.
Does GSOT05C-HG3-08 require external components for basic ESD protection?
No, GSOT05C-HG3-08 is a standalone ESD protection device requiring only proper PCB layout: short traces to protected lines, low-inductance ground connection to pin 3, and adherence to SOT-23 footprint recommendations. No series resistors or parallel capacitors are needed for standard IEC 61000-4-2 compliance.
