Product details
Overview
GSOT24C-G3-08 from Vishay Semiconductors is a two-line bidirectional ESD protection diode in SOT-23 package, rated for ±30 kV IEC 61000-4-2 contact/air discharge, 24 V reverse stand-off voltage (VRWM), and 5 A peak pulse current (IPPM), deployed in USB 2.0 data lines and industrial sensor interfaces.
For engineers reviewing the GSOT24C-G3-08 datasheet, GSOT24C-G3-08 pinout, GSOT24C-G3-08 application, or GSOT24C-G3-08 equivalent, this page delivers verified electrical specs, BiAs/BiSy dual-mode operation details, clamping behavior under transient stress, and validated alternative options for ESD-hardened signal line design.
Technical Context
The GSOT24C-G3-08 implements BiAs-MODE (bidirectional asymmetrical) protection when pins 1 and 2 connect to protected lines and pin 3 to ground - delivering distinct forward (VF ≈ 1.0–1.4 V) and reverse (VC ≈ 40–48 V at 5 A) clamping. It also supports BiSy-MODE (bidirectional symmetrical) with pin 3 unconnected, using pins 1–2 as a single 24.5 V VRWM path.
Its SOT-23 package enables compact placement on high-speed traces, with capacitance of 33–40 pF (VR = 0 V) and <18 pF (VR = 12 V), meeting USB 2.0 and RS-485 signal integrity requirements while maintaining AEC-Q101 qualification readiness and MSL level 1 soldering compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±30 kV contact/air per IEC 61000-4-2 - ensures robust immunity against human-body ESD events in handheld and industrial equipment. |
| Reverse Stand-off Voltage | 24 V (VRWM) - blocks normal operating voltages up to 24 V while remaining non-conductive on data lines like CAN FD or 24 V sensor buses. |
| Peak Pulse Current | 5 A (IPPM, 8/20 μs) - sustains surge energy without failure during lightning-induced or inductive-switching transients. |
| Clamping Voltage | 40–48 V at 5 A (reverse), ≤1.4 V at 5 A (forward) - limits voltage overshoot to safe levels for downstream 24 V-rated ICs. |
| Capacitance | 33–40 pF at 0 V, ≤18 pF at 12 V - preserves signal rise time and minimizes insertion loss in 480 Mbps USB 2.0 links. |
| Package | SOT-23 - industry-standard 3-pin footprint enabling drop-in replacement and automated assembly on dense PCBs. |
Pinout & Package
SOT-23 package: 3-pin surface-mount device with gull-wing leads, 2.8–3.1 mm length, 1.15–1.20 mm width, 0.9–1.0 mm height, MSL level 1, peak reflow ≤260 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Line 1 Anode/Cathode | Connects to first protected signal line (e.g., USB D+); forms one leg of BiAs protection path to ground (pin 3). |
| Pin 2 | Line 2 Anode/Cathode | Connects to second protected signal line (e.g., USB D−); forms second leg of BiAs protection path to ground (pin 3). |
| Pin 3 | Ground Reference | Must be connected to system ground in BiAs mode; left floating in BiSy mode (pins 1–2 only used). |
Key Features
| Feature | Design Value |
|---|---|
| BiAs-MODE dual-line protection | Simultaneously safeguards two independent signal lines (e.g., differential pairs) with shared ground reference and asymmetric clamping. |
| BiSy-MODE single-line option | Reconfigures as a symmetrical 24.5 V VRWM protector between pins 1–2, eliminating need for external ground connection. |
| AEC-Q101 qualified variant available | Meets automotive-grade reliability standards for under-hood and infotainment interface protection. |
| e3 Sn plating | Lead-free, RoHS-compliant matte tin termination compatible with standard Pb-free reflow profiles. |
| Low leakage current | IR ≤ 1 μA at 24 V - prevents signal distortion or bias shift in high-impedance sensor front-ends. |
Applications
| USB 2.0 Interface Protection | Industrial 24 V Sensor Bus |
|---|---|
Use Scenario: Protecting D+ and D− lines of embedded USB peripherals against ESD during hot-plug or field maintenance. IC Role / Device Role / Timing Role: Two-line ESD clamp placed immediately before USB transceiver, referenced to system ground. Use Value: Maintains 480 Mbps signaling integrity with <40 pF loading and clamps transients to <48 V, preventing transceiver latch-up. | Use Scenario: Safeguarding analog/digital I/O on 24 V industrial PLC modules exposed to factory-floor ESD and switching noise. IC Role / Device Role / Timing Role: Bidirectional transient suppressor on 24 V supply-sensing lines or 4–20 mA loop interfaces. Use Value: Withstands ±30 kV ESD and clamps surges to ≤48 V while drawing <1 μA leakage, preserving measurement accuracy. |
| Automotive LIN Bus Node | RS-485 Data Line Protection |
Use Scenario: ESD hardening of LIN transceivers in body control modules where space and reliability are critical. IC Role / Device Role / Timing Role: Asymmetrical clamp (BiAs) on LIN bus line with pin 3 grounded, matching LIN's 12–18 V operating range. Use Value: Provides AEC-Q101-ready protection at 24 V VRWM, ensuring compliance with ISO 10605 and reducing field return rates. | Use Scenario: Transient suppression on half-duplex RS-485 differential pairs in building automation controllers. IC Role / Device Role / Timing Role: Dual-path protector (pins 1 & 2 → A/B lines, pin 3 → ground) limiting common-mode surges. Use Value: Delivers 5 A IPPM handling and <40 pF capacitance, preserving signal edge rate and noise margin over 1200 m cables. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VGSOT24C-G3-08 | Successor series with identical SOT-23 footprint, same VRWM (24 V), but improved thermal performance and extended lifecycle beyond Jan 2025. | Drop-in replacement for new designs; requires no layout change but offers longer supply assurance. | Select for production programs requiring post-2025 availability and enhanced surge derating margin. |
| SMF24A-T | Single-line 24 V TVS diode (SOD-123), 5.5 A IPPM, higher clamping (53 V at 5 A), 100 pF capacitance. | Requires two devices for dual-line protection; unsuitable for space-constrained USB layouts due to larger footprint and higher CD. | Use only when BiAs functionality is unnecessary and board area permits discrete placement per line. |
Compared with SMF24A-T and VGSOT24C-G3-08, the GSOT24C-G3-08 uniquely integrates dual-line asymmetrical clamping in one SOT-23 device, offering lower capacitance and smaller footprint than discrete alternatives while serving as the direct predecessor to the VGSOTxxC series for legacy design continuity.

FAQ
What is the maximum reverse working voltage (VRWM) of the GSOT24C-G3-08?
The GSOT24C-G3-08 has a maximum reverse working voltage (VRWM) of 24 V when configured in two-line BiAs mode (pins 1–3 and 2–3), and 24.5 V in single-line BiSy mode (pins 1–2). This rating ensures reliable blocking of nominal 24 V system voltages while remaining fully inactive during normal operation, with leakage current limited to ≤1 μA at rated VRWM.
How does the GSOT24C-G3-08 handle ESD transients per IEC 61000-4-2?
The GSOT24C-G3-08 delivers ±30 kV ESD immunity per IEC 61000-4-2 (contact and air discharge), verified across 10 pulses. Its low clamping voltage (≤48 V at 5 A) and fast response limit voltage overshoot on protected lines, making it suitable for USB, CAN, and industrial I/O where human-accessible connectors require certified ESD resilience.
Can the GSOT24C-G3-08 be used in both BiAs and BiSy protection modes?
Yes, the GSOT24C-G3-08 supports both BiAs-MODE (bidirectional asymmetrical) with pin 3 grounded for dual-line protection, and BiSy-MODE (bidirectional symmetrical) with pin 3 unconnected and pins 1–2 used as a single 24.5 V path. This dual-mode flexibility allows one device to serve differential data lines or single-ended buses without redesigning the schematic or layout.
What is the typical capacitance of the GSOT24C-G3-08 at zero bias?
The GSOT24C-G3-08 exhibits 33–40 pF typical capacitance at 0 V reverse bias and 1 MHz, dropping to ≤18 pF at 12 V reverse bias. This low, voltage-dependent capacitance preserves signal integrity in high-speed interfaces such as USB 2.0, minimizing jitter and insertion loss while maintaining effective ESD clamping performance.
Is the GSOT24C-G3-08 qualified to AEC-Q101?
The GSOT24C-G3-08 is offered in an AEC-Q101-qualified version (e.g., GSOT24C-HG3-08), though the -G3-08 suffix denotes standard green RoHS-compliant packaging. For automotive applications, designers should specify the HG3 or HE3 variant; the GSOT24C-G3-08 itself meets all electrical and package specifications required for AEC-Q101 qualification pending final test certification.
