Product details
Overview
GSOT15-G3-08 from Vishay Semiconductors is a single-line bidirectional asymmetrical (BiAs) ESD protection diode in SOT-23 package, rated for 15 V reverse stand-off voltage (VRWM), ±30 kV IEC 61000-4-2 ESD immunity, and 8 A peak pulse current (IPPM), deployed for high-reliability data line protection in automotive infotainment interfaces.
For engineers reviewing the GSOT15-G3-08 datasheet, GSOT15-G3-08 pinout, GSOT15-G3-08 application, or GSOT15-G3-08 equivalent, key selection criteria include clamping voltage at 8 A (24.8–28.8 V), low 90–120 pF capacitance at 0 V bias, AEC-Q101 qualification, green RoHS-compliant packaging, and SOT-23 footprint compatibility with space-constrained PCB layouts.
Technical Context
The GSOT15-G3-08 implements BiAs-MODE architecture: pin 1 is grounded, pin 3 connects to the protected signal line, enabling asymmetric clamping-reverse breakdown at 16.5–20 V (VBR), forward clamping near ground (VF ≤ 1.8 V at 8 A), and distinct VC levels for positive/negative transients. It operates across –40 °C to +125 °C junction temperature.
This device delivers ESD robustness per IEC 61000-4-2 (±30 kV contact/air) and surge immunity per IEC 61000-4-5 (8/20 μs waveform), with leakage current ≤1 μA at 15 V VR and capacitance as low as 35 pF at 7.5 V reverse bias-critical for high-speed USB 2.0 or CAN FD signal integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage (VRWM) | 15 V - Maximum continuous operating voltage before conduction; defines safe signal swing range for 12 V automotive buses. |
| Peak Pulse Current (IPPM) | 8 A - Withstands IEC 61000-4-5 8/20 μs surge without failure; supports transient energy handling up to 230 W. |
| ESD Immunity | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - Meets highest industrial and automotive ESD stress requirements. |
| Clamping Voltage (VC) | 24.8–28.8 V at 8 A - Limits voltage seen by downstream IC during surge; ensures protected IC remains below absolute max ratings. |
| Capacitance | 90–120 pF at 0 V / 35 pF at 7.5 V - Low dynamic capacitance preserves signal rise time in <100 Mbps interfaces. |
| Leakage Current (IR) | ≤1 μA at 15 V - Minimizes power loss and signal distortion in always-on sensor or communication lines. |
| AEC-Q101 Qualified | Yes - Validated for automotive underhood and cabin applications per stress test requirements. |
Pinout & Package
SOT-23 package (JEDEC TO-236AB), 3-pin surface-mount, e3 Sn-plated terminals, MSL level 1, 260 °C peak reflow compatible. Dimensions: 2.8 × 2.35 × 1.15 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Ground (GND) | Low-inductance return path for ESD current; must be connected to solid system ground plane. |
| Pin 2 | No Connection (NC) | Internally unconnected; no PCB trace or thermal pad required-reduces layout complexity. |
| Pin 3 | Protected Line (L1) | Input/output signal terminal; placed in series with data line (e.g., LIN bus, sensor analog output) before IC input. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Asymmetrical (BiAs) Clamping | Enables low forward-voltage clamping (~1.8 V) for negative transients while maintaining 15 V VRWM for positive signal margin. |
| AEC-Q101 Qualification | Validated for automotive environments including temperature cycling, humidity testing, and mechanical shock-enables drop-in use in Tier-1 modules. |
| Green RoHS Compliance (G3) | e3 Sn plating and halogen-free molding compound meet global environmental mandates without compromising solderability or reliability. |
| Low Capacitance at Operating Bias | 35 pF at 7.5 V reverse bias minimizes signal attenuation and jitter in 12 V-biased sensor interfaces (e.g., pressure, temperature). |
| Space-Saving SOT-23 Footprint | Compatible with standard 0805 land pattern; enables high-density routing on compact control units without redesign. |
Applications
| Automotive LIN Bus Protection | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Protecting LIN transceiver inputs against ESD events during vehicle assembly, service, or end-user interaction. IC Role / Device Role / Timing Role: Single-line transient voltage suppressor placed between connector and LIN PHY IC input pin. Use Value: Maintains 15 V VRWM margin above LIN's 12 V nominal supply while clamping surges to ≤28.8 V-preventing latch-up in transceivers. |
Use Scenario: Safeguarding analog output lines of pressure or temperature sensors in factory automation PLC modules. IC Role / Device Role / Timing Role: ESD shunt on 0–5 V or 0–10 V analog signal path prior to ADC input stage. Use Value: 1 μA leakage at 15 V ensures minimal offset error; 35 pF at 7.5 V bias avoids bandwidth reduction in DC-coupled sensor chains. |
| USB 2.0 Data Line Shielding | Automotive Camera Power Line Filtering |
Use Scenario: Adding secondary ESD protection on D+ and D− lines alongside integrated USB PHY ESD structures. IC Role / Device Role / Timing Role: Discrete BiAs diode in parallel with data pair to lower overall clamping impedance. Use Value: 90–120 pF total capacitance meets USB 2.0 eye diagram mask; ±30 kV rating exceeds IEC 61000-4-2 Level 4 requirement. |
Use Scenario: Suppressing load-dump and jump-start transients on 12 V camera power rails in ADAS domain controllers. IC Role / Device Role / Timing Role: Front-end clamp on switched 12 V supply feeding image sensor and serializer ICs. Use Value: 230 W peak power rating handles short-duration surges; AEC-Q101 qualification ensures operation at +125 °C junction temperature. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VGSOT15 | Successor family with identical VRWM (15 V), improved CDF (≤85 pF at 0 V), and extended -55 °C to +150 °C storage range. | Targeted for new designs requiring longer product lifecycle beyond January 2025 EOL date of GSOT15-G3-08. | Select VGSOT15 when designing for production beyond Q1 2025 or requiring tighter capacitance tolerance. |
| SMF15A | Unidirectional TVS; 15 V standoff but only protects against positive transients; higher clamping (33.2 V at 8 A); SOD-123 package. | Suitable for DC-biased power rails where negative transients are absent or handled separately. | Choose SMF15A only if polarity-specific protection suffices and SOT-23 footprint is not mandatory. |
Compared with GSOT15-G3-08, VGSOT15 offers enhanced longevity and tighter parametric control for next-gen automotive platforms, while SMF15A trades bidirectional capability and low capacitance for cost-sensitive unidirectional power rail use-neither is pin-compatible, requiring layout revision.

FAQ
What is the maximum operating temperature for GSOT15-G3-08?
The GSOT15-G3-08 has a junction temperature range of –40 °C to +125 °C, validated per AEC-Q101 requirements. This allows deployment in engine bay sensors, transmission control units, and other under-hood automotive locations where ambient temperatures exceed 105 °C. The device maintains specified clamping and leakage performance across this full range.
Does GSOT15-G3-08 support bidirectional signal lines like CAN or LIN?
Yes, GSOT15-G3-08 supports bidirectional signal lines via its BiAs-MODE architecture: it clamps positive transients above 16.5 V (VBR) to ground and negative transients down to ~1.8 V (VF) at 8 A, making it suitable for LIN bus, CAN FD stubs, and other differential or open-drain interfaces where both polarities occur.
Is GSOT15-G3-08 pin-compatible with other GSOTxx variants?
No-while all GSOTxx devices share the SOT-23 package and pin 1 (GND)/pin 3 (L1) functional assignment, their electrical parameters (VRWM, IPPM, VC) differ significantly. Substituting GSOT15-G3-08 with GSOT05-G3-08 or GSOT24-G3-08 would violate voltage margin or surge handling requirements and is not recommended without circuit revalidation.
What does the "G3" suffix mean in GSOT15-G3-08?
The "G3" suffix indicates green RoHS-compliant construction: lead-free (Pb-free) with e3 matte tin plating and halogen-free molding compound, conforming to Vishay's material categorization standard (document 99912). It also denotes tape-and-reel packaging: 3,000 units per 7″ reel, 8 mm carrier tape width.
How does GSOT15-G3-08 compare to integrated ESD protection in microcontrollers?
GSOT15-G3-08 provides higher surge robustness (8 A IPPM, 230 W) than most MCU-internal ESD cells (typically rated ≤1 A), and lower clamping voltage than many external unidirectional TVS diodes. Its BiAs behavior and 35 pF capacitance at 7.5 V bias make it superior for protecting sensitive analog or high-speed digital pins where integrated protection falls short.
