Product details
Overview
GSOT08C-HG3-08 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, 8 V reverse stand-off voltage (VRWM), and 18 A peak pulse current (IPPM). It protects high-speed data lines such as USB 2.0 or HDMI interfaces against electrostatic transients.
For engineers reviewing the GSOT08C-HG3-08 datasheet, GSOT08C-HG3-08 pinout, GSOT08C-HG3-08 application, or GSOT08C-HG3-08 equivalent, key selection criteria include clamping voltage at 18 A (≤19.2 V), low 125 pF capacitance at 4 V reverse bias, AEC-Q101 qualification status, and BiAs-mode dual-line vs. BiSy-mode single-line configuration flexibility.
Technical Context
The GSOT08C-HG3-08 implements BiAs-MODE (Bidirectional Asymmetrical) protection: pins 1 and 2 connect to protected signal lines, pin 3 to ground, enabling independent clamping of positive transients (via reverse breakdown) and negative transients (via forward conduction). Its asymmetry yields lower forward clamping (~3 V at 18 A) versus reverse clamping (~19.2 V at 18 A).
In BiSy-MODE (single-line use), pin 3 is left unconnected; pins 1 and 2 form a symmetrical bipolar clamp with 8.5 V VRWM and 18.5 V clamping at 18 A. Both modes operate across –55 °C to +150 °C junction temperature and comply with AEC-Q101 stress testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±30 kV contact/air discharge per IEC 61000-4-2 - meets automotive and industrial ESD immunity requirements without external shielding. |
| VRWM (BiAs mode) | 8 V - supports 3.3 V and 5 V logic systems with margin against normal operating voltage swings. |
| IPPM (BiAs mode) | 18 A (8/20 μs) - handles typical lightning-induced surges on board-level signal traces. |
| VC @ IPPM | 19.2 V max (BiAs, pin1–pin3) - limits transient voltage seen by downstream ICs during worst-case surge. |
| Capacitance | 125 pF max at VR = 4 V, 1 MHz - suitable for USB 2.0 (480 Mbps) with minimal signal integrity impact. |
| Leakage Current | 5 μA max at 8 V - ensures negligible power loss in battery-powered sensor nodes. |
| Package | SOT-23 - enables compact placement near connectors; compatible with standard reflow profiles (260 °C peak). |
Pinout & Package
SOT-23 package: 3-pin surface-mount, 2.8 mm × 2.35 mm footprint, 1.15 mm height, e3 Sn plating, MSL Level 1, UL 94 V-0 molding compound.
| 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 dual-channel clamp. |
| Pin 2 | Line 2 Anode/Cathode | Connects to second protected signal line (e.g., USB D−); symmetric counterpart to Pin 1 in BiAs mode. |
| Pin 3 | Ground Reference | Must be connected to low-impedance system ground in BiAs mode; left floating in BiSy single-line mode. |
Key Features
| Feature | Design Value |
|---|---|
| Two-line ESD protection | Single SOT-23 device protects two independent data lines simultaneously, reducing BOM count and PCB area vs. discrete diodes. |
| BiAs/BiSy mode flexibility | Configurable for asymmetric dual-line (BiAs) or symmetrical single-line (BiSy) protection without redesigning layout. |
| AEC-Q101 qualified | Validated for automotive under-hood and infotainment applications requiring robustness over temperature and lifetime. |
| Low clamping in forward direction | Forward clamping ≤3 V at 18 A (BiAs) minimizes negative transient overshoot on grounded signal paths. |
| Green RoHS-compliant | e3 Sn termination and halogen-free molding compound meet global environmental compliance mandates. |
Applications
| USB 2.0 Interface Protection | HDMI Data Lane Protection |
|---|---|
Use Scenario: Protecting USB 2.0 D+/D− differential pair from ESD events during hot-plug insertion in portable medical devices. IC Role / Device Role / Timing Role: Two-line transient voltage suppressor placed within 2 mm of USB connector, clamping ±30 kV discharges before reaching USB PHY IC. Use Value: Prevents latch-up or damage to USB transceivers while maintaining <125 pF total capacitance to preserve 480 Mbps eye diagram integrity. | Use Scenario: Safeguarding HDMI TMDS channels against ESD in digital signage controllers exposed to frequent human contact. IC Role / Device Role / Timing Role: Dual-channel ESD clamp on each TMDS+/- pair, leveraging BiAs mode to handle common-mode and differential transients. Use Value: Enables compliance with IEC 61000-4-2 Level 4 without degrading 165 MHz pixel clock timing margins due to low 80–125 pF capacitance. |
| Automotive Infotainment Display Link | Industrial CAN FD Data Line Protection |
Use Scenario: Shielding MIPI D-PHY lanes between head unit SoC and LCD display module in vehicles operating from –40 °C to +105 °C ambient. IC Role / Device Role / Timing Role: AEC-Q101-qualified dual-line protector mounted adjacent to display flex connector, referenced to chassis ground. Use Value: Guarantees ESD survivability across full automotive temperature range while adding <2 ns propagation delay to high-speed video signals. | Use Scenario: Adding secondary ESD protection to CAN FD bus lines in factory automation gateways where primary TVS is located remotely. IC Role / Device Role / Timing Role: Low-capacitance (≤125 pF), low-leakage (5 μA) clamp used in BiSy mode on CANH/CANL, placed near controller-side connector. Use Value: Maintains CAN FD bit rate up to 5 Mbps by limiting added capacitance and avoiding DC loading on bias resistors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VGSOT08C-HG3-08 | Successor series with identical SOT-23 package, same 8 V VRWM and ±30 kV ESD rating; improved leakage (<1 μA at 8 V) and tighter VBR tolerance. | Drop-in replacement for new designs; requires validation for legacy production due to minor parametric shifts. | Select for new automotive or industrial designs requiring extended lifecycle beyond January 2025 EOL date of GSOT08C-HG3-08. |
| TPD2E001DRYR | 2-channel, 5.5 V VRWM, 12 V VC @ 1 A, 15 pF typical capacitance - lower clamping but narrower voltage range. | Better suited for 3.3 V-only interfaces like I²C or UART; insufficient for 5 V tolerant USB or HDMI. | Choose when protecting low-voltage, ultra-high-speed buses where sub-20 pF capacitance is mandatory and 5.5 V operation suffices. |
Compared with VGSOT08C-HG3-08, the original GSOT08C-HG3-08 offers proven field reliability through 2025 but lacks the tighter leakage spec; versus TPD2E001DRYR, it supports higher working voltages and surge currents at the cost of higher capacitance - making it optimal for mixed-voltage, moderate-speed data lines.

FAQ
What is the maximum operating temperature for GSOT08C-HG3-08?
The GSOT08C-HG3-08 has a specified junction temperature range of –55 °C to +150 °C, enabling reliable operation in under-hood automotive environments and industrial control cabinets. This rating is validated per AEC-Q101 stress tests and applies to both BiAs and BiSy configurations of the GSOT08C-HG3-08.
Does GSOT08C-HG3-08 support both bidirectional asymmetrical and symmetrical protection modes?
Yes, the GSOT08C-HG3-08 supports BiAs-MODE (pins 1 and 2 to signal lines, pin 3 to ground) for two-line asymmetric clamping, and BiSy-MODE (pin 3 unconnected, pins 1 and 2 across one line) for single-line symmetric clamping. The GSOT08C-HG3-08's internal dual-diode structure enables this dual-mode flexibility without external component changes.
What is the reverse leakage current specification for GSOT08C-HG3-08 at its rated VRWM?
The GSOT08C-HG3-08 specifies a maximum reverse leakage current (IR) of 5 μA at 8 V reverse voltage (VRWM), measured at 25 °C. This low leakage ensures minimal power drain in always-on sensor interfaces and preserves signal integrity in high-impedance analog monitoring circuits using the GSOT08C-HG3-08.
Is GSOT08C-HG3-08 qualified to AEC-Q101 standards?
Yes, the GSOT08C-HG3-08 is AEC-Q101 qualified, confirming its suitability for automotive applications including powertrain, body electronics, and infotainment systems.
