Product details
Overview
GSOT05-G3-08 from Vishay Semiconductors is a single-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). It protects high-speed data lines such as USB 2.0 interfaces against electrostatic discharge.
For engineers reviewing the GSOT05-G3-08 datasheet, GSOT05-G3-08 pinout, GSOT05-G3-08 application, or GSOT05-G3-08 equivalent, this device delivers low clamping voltage (12 V at 30 A), sub-350 pF capacitance at 0 V bias, AEC-Q101 qualification option, green RoHS-compliant packaging, and SOT-23 footprint compatibility with standard PCB assembly processes.
Technical Context
The GSOT05-G3-08 implements BiAs-MODE (Bidirectional Asymmetrical) protection: reverse clamping occurs above 6.8 V (typical VBR), while forward clamping holds near 1.0 V (VF) during negative transients. Its pin 1–pin 3 configuration connects ground to pin 1 and signal line to pin 3, enabling open-circuit isolation below VRWM and rapid conduction above breakdown.
This device operates across –40 °C to +125 °C junction temperature, supports MSL level 1 handling per J-STD-020, and uses Sn (e3) matte tin plating on copper leadframe. Its 8.8 mg SOT-23 package meets UL 94 V-0 flammability rating and withstands peak reflow temperatures up to 260 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 5 V - Maximum continuous working voltage before clamping begins; ensures no leakage or interference on 5 V logic/data lines. |
| Reverse Breakdown Voltage | 6.8 V (typ.) - Threshold where diode enters avalanche conduction; defines onset of transient suppression. |
| Clamping Voltage (30 A) | 12 V (typ.) - Peak voltage seen by protected circuit during worst-case 8/20 μs surge; limits stress on downstream ICs. |
| Capacitance (0 V, 1 MHz) | 260–350 pF - Low enough for USB 2.0 (480 Mbps) signal integrity; avoids excessive rise-time degradation. |
| ESD Immunity | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - Exceeds Level 4 industrial requirements; eliminates need for secondary ESD staging. |
| Peak Pulse Current | 30 A (8/20 μs, IEC 61000-4-5) - Handles lightning-induced surges in automotive and industrial environments. |
| Operating Temperature | –40 °C to +125 °C - Supports under-hood automotive, industrial control, and outdoor embedded applications. |
Pinout & Package
SOT-23 package: 3-pin, surface-mount, gull-wing leads; 2.8 mm × 2.35 mm body size; 1.15 mm height; e3 matte tin (Sn) plating; UL 94 V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Ground (Anode common) | Low-inductance return path for transient current; must connect directly to system ground plane. |
| Pin 2 | No connection (NC) | Internally unconnected; left floating or tied to ground per layout best practice to reduce parasitic coupling. |
| Pin 3 | Protected Signal Line (Cathode) | Input/output node for data or signal line; clamps transients to ground via bidirectional avalanche path. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Asymmetrical Clamping (BiAs-MODE) | Enables tight 1.0 V forward clamp and controlled 12 V reverse clamp-preserves signal integrity while maximizing protection margin. |
| AEC-Q101 Qualified Option | Validated for automotive electronics including infotainment and body control modules requiring H3B-class ESD robustness (>8 kV HBM). |
| Green RoHS Compliance | G3 suffix denotes lead-free, halogen-free, and green-compliant construction-meets global environmental regulations without performance trade-offs. |
| Low Capacitance at Operating Bias | 150 pF at 2.5 V reverse bias-minimizes loading on 5 V high-speed interfaces like UART, SPI, or CAN FD physical layer traces. |
| MSL Level 1 Rating | Unlimited floor life at ≤30 °C/60% RH; eliminates bake requirements and simplifies SMT production planning. |
Applications
| USB 2.0 Interface Protection | Automotive Infotainment Data Lines |
|---|---|
Use Scenario: Protecting D+ and D– lines of USB 2.0 ports in automotive head units and docking stations from ESD events during hot-plug insertion. IC Role / Device Role / Timing Role: Single-line transient voltage suppressor placed inline between connector and USB transceiver IC.

IC Role / Device Role / Timing Role: Front-end ESD guard for 5 V analog signal paths subject to handling discharge during field servicing. Use Value: 10 μA max reverse leakage at 5 V prevents DC offset errors; 12 V clamping prevents ADC saturation during transient events. |
Use Scenario: Securing ECG or SpO₂ front-end signal conditioning inputs in portable patient monitors where human-contact ESD is frequent. IC Role / Device Role / Timing Role: First-stage protection on isolated analog input channels prior to instrumentation amplifier stages. Use Value: BiAs clamping ensures sub-1.2 V forward voltage does not distort low-amplitude bio-signals; green compliance supports IEC 60601-1 safety certification. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VGSOT05-08 | Newer generation with identical VRWM (5 V), lower clamping (11.5 V typ. at 30 A), and reduced capacitance (220 pF typ. at 0 V). | Designed for next-gen USB-C and MIPI D-PHY interfaces requiring tighter signal fidelity. | Select VGSOT05-08 when upgrading for higher-speed interfaces or stricter EMC budgets; not drop-in due to different thermal pad design. |
| SMF5.0A | Unidirectional TVS; 5.0 V standoff; 14.5 V clamping at 25 A; 1000 pF capacitance; DO-214AA package. | Suitable only for DC-biased lines where polarity is fixed and board space allows larger package. | Choose SMF5.0A only if polarity is known and layout permits DO-214AA; avoid for bidirectional data lines like USB. |
Compared with GSOT05-G3-08, VGSOT05-08 offers improved clamping and bandwidth but requires PCB redesign, while SMF5.0A sacrifices bidirectionality and adds 3× capacitance-making GSOT05-G3-08 the optimal balance of performance, footprint, and ease of integration for legacy 5 V data lines.

FAQ
What is the maximum operating temperature for GSOT05-G3-08?
The GSOT05-G3-08 has a junction temperature range of –40 °C to +125 °C, making it suitable for under-hood automotive applications and industrial environments with elevated ambient conditions. This rating is validated per AEC-Q101 test conditions when qualified, and applies to all GSOT05-G3-08 units regardless of environmental suffix.
Does GSOT05-G3-08 support bidirectional signal lines like USB D+ and D–?
Yes, GSOT05-G3-08 uses BiAs-MODE (Bidirectional Asymmetrical) architecture, enabling symmetrical ESD protection for AC-coupled or bidirectional data lines. Its pin 1–pin 3 configuration provides matched clamping in both polarities-critical for maintaining signal integrity on USB 2.0 differential pairs without adding DC bias constraints.
Is GSOT05-G3-08 RoHS compliant and lead-free?
Yes, the "G3" suffix in GSOT05-G3-08 explicitly denotes green RoHS-compliant, lead-free, and halogen-free construction per Vishay's material categorization standard. It features e3 matte tin plating and UL 94 V-0 molding compound, fully meeting EU RoHS Directive 2011/65/EU and JEDEC JS709E requirements.
What is the clamping voltage of GSOT05-G3-08 at 30 A surge current?
The GSOT05-G3-08 exhibits a typical clamping voltage of 12 V at 30 A (8/20 μs waveform), with a maximum of 16 V per datasheet specifications. This value is measured pin 3 to pin 1 and ensures downstream ICs experience minimal overvoltage stress during IEC 61000-4-5 surge events.
Can GSOT05-G3-08 replace GSOT05-E3-08 in existing designs?
Yes, GSOT05-G3-08 is a direct replacement for GSOT05-E3-08 in terms of electrical performance, pinout, and package dimensions.
