Product details
Overview
GSOT15C-G3-08 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, 15 V reverse stand-off voltage (VRWM), and 8 A peak pulse current (IPPM), deployed in USB 2.0 data lines and industrial sensor interfaces.
For engineers reviewing the GSOT15C-G3-08 datasheet, GSOT15C-G3-08 pinout, GSOT15C-G3-08 application, or GSOT15C-G3-08 equivalent, this page delivers verified electrical specs, BiAs/BiSy dual-mode operation details, clamping behavior under 8/20 μs surge, and AEC-Q101-qualified green packaging compliance.
Technical Context
The GSOT15C-G3-08 implements BiAs-MODE (bidirectional asymmetrical) protection when pin 3 is grounded and pins 1/2 protect two independent signal lines - delivering 24.8 V clamping at 8 A IPPM in reverse direction and 1.8 V forward clamping. It also supports BiSy-MODE (bidirectional symmetrical) single-line protection with pin 3 unconnected, achieving 26.6 V clamping at 8 A across one path.
Its 90–120 pF capacitance at 0 V bias enables use in 480 Mbps USB 2.0 applications without signal integrity degradation, while its 1 μA reverse leakage at 15 V VRWM ensures low power consumption in battery-backed systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD immunity | ±30 kV contact & air discharge per IEC 61000-4-2 - meets Level 4 system-level ESD robustness for industrial and automotive ports. |
| Reverse stand-off voltage (VRWM) | 15 V - compatible with 12 V nominal supply rails and 15 V analog sensor outputs without false triggering. |
| Peak pulse current (IPPM) | 8 A per line (IEC 61000-4-5, 8/20 μs) - sustains transient surges from relay switching or inductive load dumps. |
| Clamping voltage (VC) | 24.8 V max at 8 A IPPM (BiAs mode) - limits downstream IC stress below 25 V absolute maximum ratings. |
| Capacitance (CD) | 90–120 pF at 0 V, 35 pF at 7.5 V - preserves signal rise time in high-speed digital interfaces up to 480 Mbps. |
| Package | SOT-23 - surface-mount footprint compatible with standard pick-and-place and reflow processes; MSL level 1. |
| AEC-Q101 qualified | Yes - validated for automotive under-hood and infotainment applications requiring extended temperature (-55 °C to +150 °C). |
Pinout & Package
SOT-23 package: 3-pin, gull-wing lead frame, e3 Sn plating, 8.8 mg weight, UL 94 V-0 molding compound, peak reflow ≤ 260 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Line 1 anode/cathode | Connects to first protected signal line (L1); forms one ESD path to ground via pin 3 in BiAs mode. |
| Pin 2 | Line 2 anode/cathode | Connects to second protected signal line (L2); forms second independent ESD path to ground via pin 3 in BiAs mode. |
| Pin 3 | Ground reference | Must be connected to system ground in BiAs mode; left floating in BiSy mode for single-line protection. |
Key Features
| Feature | Design Value |
|---|---|
| Two-line BiAs protection | Simultaneous protection of differential pairs (e.g., USB D+/D−) with asymmetric clamping optimized for data line polarity. |
| Dual-mode operation | Configurable as 2-line BiAs or 1-line BiSy via pin 3 connection - eliminates need for separate part numbers in mixed-signal designs. |
| Low clamping in forward direction | 1.8 V max at 8 A IPPM - minimizes negative transient overshoot on grounded signal lines. |
| Green RoHS-compliant packaging | e3 Sn plating, halogen-free molding compound, MSL level 1 - satisfies IPC/JEDEC standards for high-reliability assembly. |
| High-temperature operation | -55 °C to +150 °C junction range - supports deployment in engine control units and industrial motor drives. |
Applications
| USB 2.0 Interface Protection | Industrial Sensor Signal Lines |
|---|---|
Use Scenario: Protecting D+ and D− lines of USB 2.0 host/device ports against ESD events during hot-plug insertion. IC Role / Device Role / Timing Role: Two-line asymmetrical transient voltage suppressor placed directly at connector entry point. Use Value: 90–120 pF capacitance avoids signal distortion at 480 Mbps; ±30 kV ESD rating exceeds IEC 61000-4-2 Level 4 requirements. |
Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA, 0–10 V) from ESD in factory automation sensors. IC Role / Device Role / Timing Role: Bidirectional clamping diode between signal line and chassis ground, operating in BiAs mode. Use Value: 15 V VRWM aligns with common industrial sensor supply ranges; 1 μA leakage prevents loading of high-impedance outputs. |
| Automotive Infotainment Data Links | RS-485/RS-422 Transceiver I/O |
Use Scenario: ESD protection for LVDS or UART lines in automotive head units exposed to human touch. IC Role / Device Role / Timing Role: AEC-Q101-qualified discrete TVS array providing system-level immunity per ISO 10605. Use Value: -55 °C to +150 °C operation supports under-dash mounting; SOT-23 footprint enables compact PCB layout near connectors. |
Use Scenario: Transient suppression on differential bus lines of industrial RS-485 transceivers. IC Role / Device Role / Timing Role: Dual-path TVS configured in BiAs mode to clamp both A and B lines independently to ground. Use Value: 24.8 V clamping at 8 A ensures transceiver I/O stays within ABSMAX limits; low 35 pF @ 7.5 V maintains signal integrity over 20 Mbps. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VGSOT15C-G3-08 | Successor device with identical electrical specs, same SOT-23 package, and enhanced process control; end-of-life notice issued for GSOT15C-G3-08 (Jan 2025). | Drop-in replacement with no layout or firmware changes required; qualified for same AEC-Q101 stress tests. | Select VGSOT15C-G3-08 for new designs or long-term supply continuity beyond January 2025. |
| GSOT12C-G3-08 | Lower VRWM (12 V), higher IPPM (12 A), and higher clamping (21.2 V at 12 A) - not interchangeable without circuit review. | Better suited for 12 V rail protection where lower stand-off voltage is acceptable and higher surge margin is needed. | Use only if design requires ≥12 A surge handling and can tolerate reduced voltage margin below 15 V. |
Compared with GSOT15C-G3-08, VGSOT15C-G3-08 offers guaranteed supply continuity past EOL and identical performance, while GSOT12C-G3-08 trades stand-off voltage for higher surge capacity - making VGSOT15C-G3-08 the preferred direct upgrade path.
