Product details
Overview
VGSOT36-G3-08 from Vishay Semiconductors is a unidirectional single-line ESD protection diode in SOT-23 package, designed for high-voltage signal line protection with 36 V reverse stand-off voltage (VRWM), ±30 kV IEC 61000-4-2/ISO 10605 ESD immunity, and 400 W peak pulse power (8/20 μs). It serves as a clamping device on automotive infotainment data lines, USB 2.0 interfaces, and industrial sensor inputs where transient suppression above 30 V is required.
For engineers reviewing the VGSOT36-G3-08 datasheet, VGSOT36-G3-08 pinout, VGSOT36-G3-08 application, or VGSOT36-G3-08 equivalent, this page delivers verified electrical characteristics, BiAs-mode clamping behavior, SOT-23 terminal mapping, AEC-Q101 qualification status, and real-world ESD protection design implications - all specific to the VGSOT36-G3-08 variant.
Technical Context
The VGSOT36-G3-08 implements Bidirectional Asymmetrical (BiAs) clamping: reverse conduction begins at VBR = 39–47 V (IR = 1 mA), clamping transients up to 5.6 A (8/20 μs) with VC ≤ 71 V, while forward conduction limits negative excursions to VF ≤ 1.4 V at IPPM. Its low 45–65 pF capacitance at VR = 0 V enables use on high-speed lines without signal integrity degradation.
This device operates across –55 °C to +150 °C junction temperature, meets AEC-Q101 stress requirements including HBM Class H3B (>8 kV), and features e3 Sn plating with MSL Level 1 moisture sensitivity - enabling reflow compatibility up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 36 V - maximum continuous working voltage before clamping initiates; defines upper limit of protected signal swing. |
| VBR (min/typ/max) | 39 / 43 / 47 V at IR = 1 mA - breakdown threshold determines earliest point of reverse conduction during overvoltage events. |
| VC @ IPPM | ≤ 71 V at 5.6 A, 8/20 μs - peak clamped voltage under worst-case surge; critical for downstream IC voltage tolerance margin. |
| Capacitance | 45–65 pF at VR = 0 V, 1 MHz - low enough for <100 Mbps data lines (e.g., CAN FD, RS-485) without measurable rise-time degradation. |
| ESD Immunity | ±30 kV contact/air per IEC 61000-4-2 & ISO 10605 - exceeds automotive EMC test requirements (e.g., ISO 11452-2). |
| PPPM (8/20 μs) | 400 W - energy-handling capability for lightning-induced surges per IEC 61000-4-5 Level 3 (1 kV line-to-ground). |
| TJ max | +150 °C - supports under-hood automotive placement and industrial environments with minimal derating. |
Pinout & Package
SOT-23 package: 3-pin, surface-mount, gull-wing leads; 2.9 mm × 1.3 mm × 1.01 mm body; e3 Sn termination; MSL Level 1; RoHS-compliant and lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Ground (Anode connection for forward clamp) | Low-impedance return path for both positive and negative transients; must connect directly to system ground plane. |
| Pin 2 | No internal connection | Electrically isolated; no PCB trace or thermal pad required; avoids unintended parasitic coupling. |
| Pin 3 | Protected Line (Cathode connection for reverse clamp) | Connects to signal/data line (e.g., LIN bus, analog sensor output); clamps to Pin 1 when voltage exceeds VRWM. |
Key Features
| Feature | Design Value |
|---|---|
| BiAs-mode clamping | Asymmetric response: reverse clamping at ~43 V, forward clamping at ≤1.4 V - preserves signal DC bias while suppressing bidirectional transients. |
| AEC-Q101 qualified | Qualified for automotive applications including engine control modules and ADAS sensor interfaces per stress test requirements. |
| Low leakage current | IR ≤ 1 μA at VR = 36 V - prevents loading of high-impedance sensor outputs or battery-powered circuits. |
| High ESD robustness | ±30 kV air/contact discharge - eliminates need for secondary TVS stages in cost-sensitive consumer and industrial designs. |
| Thermal reliability | Junction-to-lead thermal impedance ≤ 100 K/W - sustains repeated surge events without thermal runaway in compact layouts. |
Applications
| Automotive LIN Bus Protection | Industrial Analog Sensor Interface |
|---|---|
Use Scenario: Protecting LIN transceiver pins against load dump and ESD in vehicle body control modules. IC Role / Device Role / Timing Role: Standalone ESD/transient suppressor placed between LIN PHY and connector. Use Value: Maintains 19.2 kbps LIN timing integrity by limiting clamping voltage to ≤71 V while adding only 45–65 pF capacitance. |
Use Scenario: Shielding 4–20 mA current-loop sensor inputs from field-induced surges in factory automation systems. IC Role / Device Role / Timing Role: Front-end transient guard for precision op-amp input stages. Use Value: Prevents op-amp latch-up with ≤1 μA leakage at 36 V, ensuring long-term calibration stability in 24 V loop-powered systems. |
| USB 2.0 Data Line Protection | RS-485 Transceiver I/O Protection |
Use Scenario: Safeguarding D+ and D– lines of embedded USB hosts against user-port ESD in medical devices. IC Role / Device Role / Timing Role: Unidirectional clamp on each data line referenced to local ground. Use Value: Enables full-speed (12 Mbps) operation with <1% signal distortion due to low 45–65 pF capacitance and sub-1.4 V forward clamp. |
Use Scenario: Hardening RS-485 transceiver A/B terminals against lightning-induced surges in outdoor SCADA networks. IC Role / Device Role / Timing Role: Primary surge suppression stage upstream of integrated transceiver ESD diodes. Use Value: Absorbs 400 W (8/20 μs) surges without degradation, extending transceiver lifetime in unshielded cable runs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A | Unidirectional, DO-214AC package, higher VRWM (36 V), but larger footprint (4.5 × 2.7 mm) and higher capacitance (150 pF). | Less suitable for space-constrained PCBs or high-speed lines >10 Mbps due to parasitic capacitance and slower response. | Select VGSOT36-G3-08 for SOT-23-compatible layouts requiring <65 pF and automotive qualification. |
| TPD2E001DRYR | Two-channel, bidirectional, 0.65 pF typical capacitance, but lower VRWM (5.5 V) and PPPM (120 W). | Only viable for low-voltage digital I/O (e.g., I²C, GPIO); cannot protect 36 V-rated analog or LIN signals. | Choose VGSOT36-G3-08 when protecting lines operating near 36 V or requiring ≥400 W surge handling. |
Compared with SMAJ36A and TPD2E001DRYR, the VGSOT36-G3-08 uniquely balances high-voltage standoff (36 V), low capacitance (<65 pF), automotive qualification, and SOT-23 miniaturization - making it optimal for next-generation compact, high-reliability signal protection where both voltage range and speed matter.

FAQ
What is the exact reverse stand-off voltage (VRWM) of VGSOT36-G3-08?
The VGSOT36-G3-08 has a guaranteed maximum reverse stand-off voltage (VRWM) of 36 V, meaning it remains non-conductive up to this DC or steady-state AC voltage level on the protected line (Pin 3) relative to ground (Pin 1). This value is confirmed in the Electrical Characteristics table on page 8 of Vishay document 86326, revision 1.1.
Does VGSOT36-G3-08 meet AEC-Q101 qualification requirements?
Yes, VGSOT36-G3-08 is AEC-Q101 qualified, as explicitly stated in the Features section of the Vishay datasheet (document 86326, page 1). It passes stress tests including human body model (HBM) Class H3B (>8 kV), mechanical shock, temperature cycling, and high-temperature operating life - validating its suitability for automotive under-hood and cabin applications.
What is the clamping voltage (VC) of VGSOT36-G3-08 under a 5.6 A, 8/20 μs surge?
Under a 5.6 A, 8/20 μs surge (the rated peak pulse current IPPM), the VGSOT36-G3-08 clamps to a maximum of 71 V, as specified in the Electrical Characteristics table (page 8, document 86326). This VC value ensures downstream ICs with 75 V absolute maximum ratings remain within safe operating limits during surge events.
How does the BiAs-mode operation of VGSOT36-G3-08 affect circuit design?
BiAs-mode means VGSOT36-G3-08 clamps asymmetrically: reverse transients (positive spikes) trigger at ~43 V (VBR), while forward transients (negative spikes) clamp tightly near 0 V (VF ≤ 1.4 V). This preserves DC bias on unidirectional signal lines like LIN or analog sensors without requiring external biasing networks - simplifying layout and reducing component count.
Is Pin 2 of VGSOT36-G3-08 electrically connected internally?
No, Pin 2 of VGSOT36-G3-08 is not internally connected to any die structure - it is a floating, unused terminal. The Vishay package drawing (page 10, document 86326) and Absolute Maximum Ratings table confirm that only Pins 1 (ground) and 3 (protected line) carry functional current. PCB footprints should leave Pin 2 unconnected.
