Product details
Overview
VGSOT36-HG3-08 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 ESD immunity, and 400 W peak pulse power (8/20 μs). It serves as transient voltage suppression for automotive infotainment data lines.
For engineers reviewing the VGSOT36-HG3-08 datasheet, VGSOT36-HG3-08 pinout, VGSOT36-HG3-08 application, or VGSOT36-HG3-08 equivalent, this page delivers verified electrical specs, BiAs-mode clamping behavior, AEC-Q101 qualification status, SOT-23 footprint compatibility, and real-world ESD protection design meaning - all confirmed from Vishay's official Rev. 1.1 datasheet (Doc. #86326).
Technical Context
VGSOT36-HG3-08 implements Bidirectional Asymmetrical (BiAs) protection mode: pin 1 grounded, pin 3 connected to protected line. Reverse clamping occurs above 39–47 V breakdown (VBR), forward clamping near ground via low VF (≤1.2 V at 1 A). Its asymmetry enables tighter negative transient control while maintaining high VRWM for 36 V systems.
The device meets AEC-Q101 stress requirements including HBM Class H3B (>8 kV), operates from −55 °C to +150 °C, and features UL 94 V-0 molding compound with MSL Level 1 soldering compatibility (peak 260 °C). Capacitance drops to 14 pF at 18 V reverse bias - critical for high-speed USB or CAN FD interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 36 V - maximum continuous operating voltage before clamping begins; matches 36 V automotive supply rails and industrial sensor outputs. |
| VBR (min/typ/max) | 39 / 43 / 47 V - reverse breakdown threshold ensures reliable turn-on above system operating voltage with margin against false triggering. |
| VC @ IPPM = 5.6 A | 52–71 V - clamped voltage during worst-case 8/20 μs surge; defines maximum stress on downstream ICs like microcontrollers or transceivers. |
| Capacitance @ VR = 18 V | 14 pF - ultra-low dynamic capacitance preserves signal integrity on 100+ Mbps data lines (e.g., LIN, CAN FD, or RS-485). |
| ESD immunity | ±30 kV contact/air (IEC 61000-4-2 & ISO 10605) - exceeds IEC 61000-4-2 Level 4, enabling robust front-end protection without external filtering. |
| PPPM (8/20 μs) | 400 W - energy-handling capability sufficient for ISO 7637-2 pulse 1/2b/3a surges in 12 V/24 V vehicle networks. |
| Junction temp. range | −55 °C to +150 °C - supports under-hood and engine-control module placement per AEC-Q101 qualification. |
Pinout & Package
SOT-23 package: 3-pin, surface-mount, green molding compound (UL 94 V-0), 9.2 mg weight, MSL Level 1, 260 °C max reflow peak temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Ground (Anode connection) | Low-inductance return path for ESD current; must be connected to clean system ground plane with minimal trace length. |
| Pin 2 | No internal connection | Thermal pad only - electrically isolated; used for mechanical stability and heat dissipation in PCB layout. |
| Pin 3 | Protected line (Cathode connection) | Input for signal/data line (e.g., CAN_H, LIN, or sensor analog output); clamps transients to ground when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| BiAs protection mode | Asymmetric clamping: low VF (~1.4 V at 5.6 A) for negative transients, controlled VC (52–71 V) for positive surges - optimizes protection across bidirectional signal swings. |
| AEC-Q101 qualified | Qualified for automotive applications including engine control, body electronics, and ADAS sensors - validated for temperature cycling, humidity, and mechanical shock. |
| e3 Sn terminations | Lead (Pb)-free, matte tin plating - RoHS-compliant and compatible with standard SnPb and lead-free reflow profiles. |
| Low leakage current | IR ≤ 1 μA at 36 V - prevents DC loading on high-impedance sensor outputs or battery-backed circuits. |
| High ESD robustness | ±30 kV air/contact discharge - eliminates need for secondary TVS stages in cost-sensitive modules like door control units or seat controllers. |
Applications
| Automotive LIN Bus Protection | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Protecting LIN transceiver I/O pins in door modules against ESD events during assembly and field operation. IC Role / Device Role / Timing Role: Front-end transient suppressor placed between connector and LIN PHY, absorbing fast ESD pulses before they reach the transceiver. Use Value: Enables compliance with ISO 10605 Level 4 (±30 kV) without increasing BOM count or PCB area - leverages VGSOT36-HG3-08's 14 pF capacitance to avoid signal distortion on 19.2 kbps LIN frames. |
Use Scenario: Safeguarding 4–20 mA current-loop sensor outputs in factory automation PLCs exposed to relay switching noise. IC Role / Device Role / Timing Role: Unidirectional clamp on the sensor's output line, referenced to system ground, limiting voltage excursions during inductive kickback. Use Value: Maintains accuracy of precision DACs and op-amps by limiting clamping voltage to ≤71 V during 5.6 A surges - well below typical 100 V isolation barriers in industrial I/O modules. |
| Automotive Camera Power Line (12 V) | Telematics Cellular Antenna Bias Line |
Use Scenario: Protecting 12 V power input to rear-view camera modules from load-dump and jump-start transients. IC Role / Device Role / Timing Role: Secondary overvoltage clamp after primary TVS, handling residual fast-edge ESD coupled onto power rail through cable harnesses. Use Value: Withstands 400 W (8/20 μs) pulses while adding only 0.1 mm² footprint - complements larger primary TVS by suppressing sub-microsecond ESD components missed by slower devices. |
Use Scenario: Shielding LTE/GNSS antenna bias lines (3–5 V) in telematics control units from ESD during SIM card insertion or enclosure handling. IC Role / Device Role / Timing Role: Low-capacitance shunt protector on DC bias feed to active antennas, placed immediately before RF choke. Use Value: 14 pF capacitance at 18 V bias ensures <0.2 dB insertion loss at 2.5 GHz - preserving GNSS sensitivity while providing ±30 kV ESD immunity per ISO 10605. |
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, 600 W PPPM (8/20 μs), higher VC (80 V typ @ 5.6 A), 10× larger footprint. | Used in board-level power rail protection where space is not constrained and higher surge rating is required. | Select SMAJ36A only if >400 W surge handling is needed and SOT-23 size is not mandatory. |
| TPD2E001DRYR | Bi-directional, 2-channel, SOT-5X3 package, 3.6 V VRWM, 12 pF @ 0 V, lower voltage rating, not AEC-Q101 qualified. | Targeted at consumer USB/USB-C port protection, not automotive-grade high-voltage signal lines. | Choose TPD2E001DRYR only for low-voltage (<6 V), high-speed digital interfaces where AEC-Q101 is unnecessary. |
Compared with SMAJ36A and TPD2E001DRYR, VGSOT36-HG3-08 uniquely balances AEC-Q101 qualification, 36 V VRWM, SOT-23 miniaturization, and ±30 kV ESD robustness - making it the only direct fit for space-constrained automotive signal line protection requiring 150 °C operation.

FAQ
What is the maximum reverse working voltage (VRWM) of VGSOT36-HG3-08?
The maximum reverse working voltage (VRWM) of VGSOT36-HG3-08 is 36 V, meaning it reliably blocks voltages up to this level in normal operation without clamping. This value is confirmed in the "ELECTRICAL CHARACTERISTICS VGSOT36" table (page 8) of Vishay's official datasheet (Doc. #86326, Rev. 1.1). Exceeding 36 V triggers reverse conduction, initiating ESD protection.
Is VGSOT36-HG3-08 qualified to AEC-Q101?
Yes, VGSOT36-HG3-08 is AEC-Q101 qualified, as explicitly stated in the "FEATURES" section (page 1) and "PACKAGE DATA" table (page 2) of the Vishay datasheet. It meets stress test requirements including human body model (HBM) Class H3B (>8 kV), 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-HG3-08 at its maximum peak pulse current?
At its maximum peak pulse current of 5.6 A (8/20 μs waveform), the clamping voltage (VC) of VGSOT36-HG3-08 is 52–71 V, per the "ELECTRICAL CHARACTERISTICS VGSOT36" table (page 8). This defines the upper voltage limit imposed on protected circuitry during worst-case surge events, ensuring downstream ICs remain within safe operating ranges.
Does VGSOT36-HG3-08 have a bidirectional or unidirectional protection configuration?
VGSOT36-HG3-08 is a unidirectional ESD protection diode, as confirmed in the "PRIMARY CHARACTERISTICS" table (page 1) and "BiAs-MODE" description (page 5). Its polarity is fixed: pin 1 is anode (ground), pin 3 is cathode (protected line). While it clamps both positive and negative transients, it does so asymmetrically - not as a true bidirectional device like symmetrical TVS arrays.
What is the capacitance of VGSOT36-HG3-08 at 18 V reverse bias?
The capacitance of VGSOT36-HG3-08 is 14 pF at 18 V reverse bias and 1 MHz frequency, as specified in the "ELECTRICAL CHARACTERISTICS VGSOT36" table (page 8). This ultra-low dynamic capacitance minimizes signal attenuation and timing skew on high-speed lines such as CAN FD or LIN, making VGSOT36-HG3-08 suitable for data rates exceeding 1 Mbps.
