Product details
Overview
VGSOT15C-HG3-08 from Vishay Semiconductors is a two-line unidirectional ESD protection diode in SOT-23 package, featuring 15 V reverse stand-off voltage (VRWM), ±30 kV IEC 61000-4-2 ESD immunity, 450 W peak pulse power (8/20 μs), 15.5 A peak pulse current, and common-anode dual-diode configuration for data line protection in automotive infotainment interfaces.
For engineers reviewing the VGSOT15C-HG3-08 datasheet, VGSOT15C-HG3-08 pinout, VGSOT15C-HG3-08 application, or VGSOT15C-HG3-08 equivalent, this page delivers verified electrical specs, BiAs/BiSy mode operation details, SOT-23 terminal mapping, real-world use cases in USB 2.0 and CAN FD interfaces, and validated alternative parts with documented differences.
Technical Context
The VGSOT15C-HG3-08 implements a dual-diode common-anode structure enabling BiAs-MODE (bidirectional asymmetrical clamping) when pin 3 is grounded and pins 1/2 protect separate signal lines - delivering 23.5 V max clamping at 15.5 A (8/20 μs). It also supports BiSy-MODE (bidirectional symmetrical clamping) as a single-line device with pins 1–2 active and pin 3 floating, achieving 26.6 V max clamping at same current.
Its 100–120 pF capacitance at 0 V (1 MHz) and 43 pF at 7.5 V enables low-distortion protection of high-speed interfaces up to 480 Mbps, while its AEC-Q101 qualification, MSL Level 1 rating, and e3 Sn terminations ensure suitability for automotive PCB assembly and under-hood environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Device Type | Two-line unidirectional ESD protection diode, common-anode dual-channel |
| VRWM | 15 V - maximum continuous reverse working voltage before leakage exceeds 1 μA; sets upper limit for protected signal swing |
| IPP (8/20 μs) | 15.5 A - peak surge current handling capacity per channel; defines transient energy absorption capability |
| PPP (8/20 μs) | 450 W - peak pulse power dissipation per channel; determines thermal robustness during ESD events |
| Clamping Voltage VC | 23.5 V max at IPP = 15.5 A (8/20 μs) - actual voltage seen by protected IC during worst-case surge |
| Capacitance CD | 100–120 pF at 0 V / 1 MHz - signal integrity impact on high-speed lines; drops to 43 pF at 7.5 V bias |

Pinout & Package
SOT-23 surface-mount package (JEDEC TO-236AB), 9.2 mg weight, UL 94 V-0 molding compound, MSL Level 1, peak reflow temperature 260 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Channel 1 | Connects to first protected signal line (L1); forms one half of common-anode dual-diode pair |
| Pin 2 | Anode of Channel 2 | Connects to second protected signal line (L2); shares cathode (pin 3) with Pin 1 for BiAs operation |
| Pin 3 | Common Cathode | Ground reference for both channels in BiAs-MODE; left unconnected in BiSy-MODE (pins 1–2 only) |
Key Features
| Feature | Design Value |
|---|---|
| BiAs-MODE operation | Enables independent protection of two signal lines (e.g., CAN_H/CAN_L) with asymmetric clamping: low VF (~2.2 V) for negative transients, controlled VC (~23.5 V) for positive surges |
| BiSy-MODE capability | Supports single-line bidirectional protection (e.g., USB D+/D−) using pins 1–2 only, delivering symmetrical clamping (26.6 V max at 15.5 A) |
| AEC-Q101 qualification | Validated for automotive applications including engine control units and ADAS sensor interfaces with operating range −55 °C to +150 °C junction temperature |
| e3 Sn terminations | RoHS-compliant matte tin plating ensures solderability and intermetallic reliability in lead-free reflow processes |
| Low leakage current | IR ≤ 1 μA at VR = 15 V minimizes DC loading on sensitive analog or low-power digital signal paths |
Applications
| Automotive CAN FD Interface Protection | Industrial USB 2.0 Port Protection |
|---|---|
Use Scenario: Protecting CAN FD transceivers in vehicle body control modules against ESD events during connector mating/unmating and cable discharge. IC Role / Device Role / Timing Role: Dual-channel ESD clamp placed between transceiver pins and connector, with pin 3 grounded and pins 1/2 connected to CAN_H/CAN_L lines. Use Value: Maintains signal integrity with 100 pF capacitance while clamping 15.5 A surges to ≤23.5 V - below CAN FD receiver absolute maximum rating of 40 V. |
Use Scenario: Safeguarding USB 2.0 data lines (D+/D−) on programmable logic controllers exposed to field service personnel handling. IC Role / Device Role / Timing Role: Single-line BiSy configuration (pins 1–2 active, pin 3 open) providing symmetrical clamping for differential signaling. Use Value: Delivers ±30 kV ESD immunity without degrading 480 Mbps data rate due to low 50–60 pF capacitance in BiSy mode at 15.5 V VRWM. |
| Consumer HDMI Hot-Plug Detection Line Protection | Medical Sensor Interface Transient Suppression |
Use Scenario: Shielding HDMI hot-plug detect (HPD) line from user-induced ESD during cable insertion into display panels. IC Role / Device Role / Timing Role: Single-channel unidirectional protection (pin 1–3 path) with VRWM = 15 V matching typical HPD logic-high level. Use Value: Limits clamping voltage to ≤23.5 V during 15.5 A transients, preventing latch-up in downstream level-shifters while drawing only 1 μA leakage at 15 V. |
Use Scenario: Protecting analog front-end inputs of wearable ECG monitors from electrostatic discharge during patient handling. IC Role / Device Role / Timing Role: Low-capacitance (100 pF) dual-channel clamp on differential sensor leads, grounded via pin 3. Use Value: Preserves signal fidelity with <120 pF total capacitance and <1 μA leakage, ensuring minimal gain error and offset drift in precision instrumentation amplifiers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A | Single-line unidirectional TVS; 15 V VRWM, 23.2 V VC @ 15.5 A, 1500 W PPP (8/20 μs), DO-214AC package | Requires two devices for dual-line protection; higher capacitance (≈200 pF) limits high-speed use | Select when higher surge power is needed and board space allows discrete placement per line |
| TPD2EUSB30DR | Two-line unidirectional ESD protector; 5.5 V VRWM, 0.8 pF per line, 3.6 V VC @ 1 A, SOT-5X3 package | Lower VRWM restricts use to 3.3 V systems; ultra-low capacitance targets USB 3.0/PCIe | Prefer for high-speed interfaces below 5.5 V; not suitable for 12–24 V automotive signal lines |
Compared with SMAJ15A and TPD2EUSB30DR, VGSOT15C-HG3-08 uniquely balances 15 V VRWM, dual-line integration in SOT-23, and 100 pF capacitance - making it optimal for cost-sensitive, space-constrained CAN FD and industrial USB 2.0 designs requiring AEC-Q101 compliance.

FAQ
What is the maximum reverse working voltage (VRWM) of the VGSOT15C-HG3-08?
The VGSOT15C-HG3-08 has a maximum reverse working voltage (VRWM) of 15 V, defined as the highest DC or continuous peak reverse voltage at which leakage current remains ≤1 μA. This value ensures compatibility with 12 V automotive signal lines and industrial 15 V logic interfaces while maintaining low standby power consumption.
How does the VGSOT15C-HG3-08 support dual-line ESD protection?
The VGSOT15C-HG3-08 supports dual-line protection via its common-anode configuration: pins 1 and 2 serve as anodes for two independent diodes sharing pin 3 as the common cathode. When pin 3 is grounded, each input line (L1/L2) connects to pins 1 and 2 respectively, enabling simultaneous BiAs-MODE clamping with asymmetric forward/reverse response.
Can the VGSOT15C-HG3-08 be used for bidirectional symmetrical protection?
Yes - the VGSOT15C-HG3-08 supports BiSy-MODE by connecting only pins 1 and 2 to a single signal line (with pin 3 left unconnected), delivering symmetrical clamping: 26.6 V max at 15.5 A (8/20 μs). This mode is ideal for differential interfaces like USB 2.0 where equal positive/negative transient suppression is required.
What is the clamping voltage of the VGSOT15C-HG3-08 under full-rated surge current?
Under 15.5 A peak pulse current (8/20 μs waveform), the VGSOT15C-HG3-08 clamps to a maximum of 23.5 V in BiAs-MODE (pins 1–3 or 2–3 path). In BiSy-MODE (pins 1–2), clamping reaches 26.6 V at the same current - both values remain well below typical IC absolute maximum ratings for 12–24 V systems.
Is the VGSOT15C-HG3-08 qualified for automotive applications?
Yes - the VGSOT15C-HG3-08 is AEC-Q101 qualified, rated for junction temperatures from −55 °C to +150 °C, and manufactured with e3 matte tin terminations. Its SOT-23 package meets MSL Level 1 moisture sensitivity requirements, supporting reliable reflow soldering in automotive PCB assembly processes.
