Product details
Overview
GSOT36C-HG3-08 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, 36 V reverse stand-off voltage (VRWM), and 3.5 A peak pulse current (IPPM), deployed for high-voltage data line protection in automotive infotainment and industrial communication interfaces.
For engineers reviewing the GSOT36C-HG3-08 datasheet, GSOT36C-HG3-08 pinout, GSOT36C-HG3-08 application, or GSOT36C-HG3-08 equivalent, this page delivers verified electrical specs, BiAs/BiSy dual-mode operation details, SOT-23 terminal mapping, real-world clamping behavior at 3.5 A, and qualified AEC-Q101 alternatives for automotive-grade design continuity.
Technical Context
The GSOT36C-HG3-08 implements BiAs-MODE (bidirectional asymmetrical) protection when pins 1 and 2 connect to signal lines and pin 3 to ground-enabling independent clamping of positive transients via reverse breakdown (VBR = 39–47 V) and negative transients via forward conduction (VF ≤ 1.3 V at 3.5 A). It also supports BiSy-MODE (bidirectional symmetrical) as a single-line protector with pins 1 and 2 forming the protected path and pin 3 unconnected.
In BiAs configuration, it delivers 59–71 V reverse clamping (VC) at 3.5 A IPPM and 52–65 pF capacitance at 0 V bias, while BiSy mode reduces capacitance to 26–33 pF and raises VRWM to 36.5 V-making it suitable for both high-isolation and low-capacitance interface protection without layout change.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Immunity | ±30 kV contact & air discharge per IEC 61000-4-2 - meets highest system-level ESD robustness requirements for exposed ports. |
| Reverse Stand-off Voltage | 36 V (BiAs mode) / 36.5 V (BiSy mode) - protects 3.3 V, 5 V, 12 V, and 24 V logic/data lines without leakage or false triggering. |
| Peak Pulse Current | 3.5 A per line (IEC 61000-4-5, 8/20 μs) - sustains surge events common in CAN, LIN, RS-485, and USB-C hot-plug scenarios. |
| Clamping Voltage | 59–71 V at 3.5 A (BiAs) / 60–72 V at 3.5 A (BiSy) - limits transient overvoltage to safe levels for downstream 36 V-rated ICs. |
| Capacitance | 52–65 pF (BiAs, 0 V) / 26–33 pF (BiSy, 0 V) - enables use on high-speed lines up to ~100 Mbps without signal integrity degradation. |
| Operating Temperature | −55 °C to +150 °C - qualified for under-hood automotive and industrial environments per AEC-Q101. |
Pinout & Package
SOT-23 package (3-pin, standard leadframe, e3 Sn plating, MSL level 1, 260 °C max reflow), footprint compliant with JEDEC TO-236AB, dimensions 2.8 × 2.35 × 1.15 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Line 1 Anode/Cathode | Connects to first protected signal line (L1); forms one half of BiAs protection path to ground (pin 3) or BiSy path to pin 2. |
| Pin 2 | Line 2 Anode/Cathode | Connects to second protected signal line (L2) in BiAs mode; serves as complementary terminal to pin 1 in BiSy mode. |
| Pin 3 | Ground Reference | Must be connected to system ground in BiAs mode; left floating in BiSy mode - defines protection topology and clamping reference. |
Key Features
| Feature | Design Value |
|---|---|
| Two-line ESD protection | Single SOT-23 device protects two independent data lines simultaneously - reduces BOM count and PCB area vs. discrete diodes. |
| Bidirectional asymmetrical (BiAs) mode | Enables low-forward-voltage clamping (<1.3 V) for negative transients and controlled reverse breakdown (39–47 V) for positives - ideal for unidirectional bus signaling with ground reference. |
| Bidirectional symmetrical (BiSy) mode | Reconfigures as single-line protector with matched positive/negative clamping - supports differential buses like RS-485 or CAN where polarity symmetry matters. |
| AEC-Q101 qualified | Validated for automotive applications including infotainment, body control, and ADAS sensor interfaces - ensures reliability across temperature and lifetime stress tests. |
| Low leakage & high isolation | IR ≤ 1 μA at 36 V - prevents signal distortion or power drain in always-on systems such as telematics and remote keyless entry receivers. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VGSOT36C-HG3-08 | Successor series with identical SOT-23 footprint, same 36 V VRWM and ±30 kV ESD rating, improved thermal resistance and extended lifecycle beyond Jan 2025 EOL date. | Drop-in replacement for new designs; requires no layout change but offers longer supply assurance and updated qualification. | Select for production ramp after Q2 2025 or for long-lifecycle programs requiring >5-year component availability. |
| SM712-08HT | Higher 12 A IPPM and 150 W PPP, but larger SOT-23-6 package and 12 V VRWM - not voltage-compatible with 36 V systems. | Only suitable for lower-voltage interfaces like RS-232 or Ethernet PHYs; cannot replace GSOT36C-HG3-08 in 24/36 V automotive lines. | Consider only if upgrading to higher-surge zones and redesigning PCB layout for SOT-23-6; not a functional substitute for GSOT36C-HG3-08's voltage range. |
Compared with GSOT36C-HG3-08, VGSOT36C-HG3-08 provides identical electrical performance with enhanced manufacturing longevity, while SM712-08HT trades voltage compatibility for higher surge capacity - making the former the preferred direct migration path and the latter a non-interchangeable alternative for different voltage classes.
