Product details
Overview
VGSOT15-HG3-08 from Vishay Semiconductors is a unidirectional single-line ESD protection diode in SOT-23 package, designed for data line protection in automotive and industrial interfaces. It features 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 100–120 pF capacitance at 0 V bias - enabling robust transient suppression in USB 2.0, CAN FD, and sensor signal paths.
For engineers reviewing the VGSOT15-HG3-08 datasheet, VGSOT15-HG3-08 pinout, VGSOT15-HG3-08 application, or VGSOT15-HG3-08 equivalent, this page delivers verified electrical parameters, BiAs-mode clamping behavior, AEC-Q101 qualification status, SOT-23 terminal mapping, and real-world use cases in automotive infotainment and industrial I/O protection.
Technical Context
The VGSOT15-HG3-08 implements Bidirectional Asymmetrical (BiAs) clamping: reverse conduction above 16.5–20 V breakdown (VBR) with clamping voltage ≤28.8 V at 15.5 A, and forward conduction below ground with VF ≤2.2 V at same current. Its 1 μA reverse leakage at 15 V VRWM ensures minimal signal loading on protected lines.
This device operates across –55 °C to +150 °C junction temperature, meets AEC-Q101 stress requirements including H3B-class human body model (>8 kV), and uses Sn (e3) terminations compatible with lead-free reflow per J-STD-020 MSL level 1 (peak 260 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 15 V - maximum continuous working voltage before clamping begins; matches 12 V automotive supply rails with margin. |
| VBR (min/typ/max) | 16.5 / 18 / 20 V - reverse breakdown threshold defining turn-on point for transient suppression. |
| VC @ IPPM = 15.5 A | ≤28.8 V - peak clamping voltage during worst-case 8/20 μs surge; limits downstream IC stress. |
| Capacitance @ 0 V | 100–120 pF - low enough for USB 2.0 (480 Mbps) and CAN FD (5 Mbps) without signal integrity degradation. |
| ESD immunity | ±30 kV contact/air discharge (IEC 61000-4-2 & ISO 10605) - exceeds Level 4 system-level ESD requirements. |
| PPPM (8/20 μs) | 450 W - energy-handling capability sufficient for IEC 61000-4-5 surge events in industrial control inputs. |
| TJ max. | +150 °C - supports under-hood automotive placement and high-ambient industrial environments. |
Pinout & Package
SOT-23 package: 3-pin, surface-mount, green molding compound (UL 94 V-0), 9.2 mg weight, MSL level 1, compatible with standard 8 mm tape handling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Ground (cathode connection) | Low-inductance return path for transient current; must be connected to clean system ground plane. |
| Pin 2 | No internal connection | Thermal pad not electrically active; serves mechanical stability only - no PCB trace required. |
| Pin 3 | Protected line (anode) | Connects directly to signal/data line (e.g., CAN_H, USB_D+, sensor output); clamps transients to Pin 1. |
Key Features
| Feature | Design Value |
|---|---|
| BiAs-mode clamping | Asymmetric forward/reverse clamping enables precise ground-referenced protection without bidirectional leakage trade-offs. |
| AEC-Q101 qualified | Qualified for automotive applications including engine control, ADAS sensors, and infotainment interfaces. |
| e3 Sn termination | Lead-free, RoHS-compliant tin plating ensures compatibility with Pb-free soldering and long-term reliability. |
| Low IR at VRWM | ≤1 μA reverse leakage at 15 V ensures negligible DC loading on high-impedance sensor or communication lines. |
| MSL level 1 rating | Unlimited floor life and 260 °C peak reflow tolerance simplify manufacturing and eliminate bake requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A | Higher VRWM (15 V), but bidirectional, higher capacitance (200 pF), larger SMA package (5.3 × 4.3 mm). | Not suitable for high-speed data lines; better for power rail or low-frequency analog protection. | Select when board space permits larger footprint and bidirectional clamping is acceptable. |
| TPD2E001DRYR | Lower VRWM (5.5 V), dual-channel, 10 pF capacitance, same SOT-23-3 package, but not AEC-Q101 qualified. | Optimized for USB/DisplayPort; lacks automotive qualification and high-voltage standoff. | Select for consumer-grade high-speed interfaces where 15 V standoff is unnecessary and ultra-low capacitance is critical. |
Compared with SMAJ15A and TPD2E001DRYR, VGSOT15-HG3-08 uniquely combines AEC-Q101 qualification, 15 V standoff, 100–120 pF capacitance, and SOT-23 size - making it the only option meeting automotive sensor interface requirements without layout or qualification compromises.

FAQ
What is the maximum operating temperature for VGSOT15-HG3-08?
The VGSOT15-HG3-08 has a maximum junction temperature (TJ) of +150 °C and operates from –55 °C to +150 °C. This rating enables deployment in under-hood automotive locations and high-ambient industrial enclosures. The device's thermal impedance and SOT-23 package allow sustained operation at rated power within this range. VGSOT15-HG3-08 must be mounted on a PCB with adequate copper area to maintain TJ ≤150 °C under worst-case surge conditions.
Is VGSOT15-HG3-08 qualified to AEC-Q101?
Yes, VGSOT15-HG3-08 is AEC-Q101 qualified and rated for H3B-class human body model (>8 kV). It passes all stress tests including temperature cycling, humidity bias, and ESD per AEC-Q101 Rev D. The "HG" in the part number denotes AEC-Q101 qualification and green (lead-free) environmental status. VGSOT15-HG3-08 is approved for use in automotive powertrain, chassis, and infotainment systems.
What is the clamping voltage of VGSOT15-HG3-08 at 15.5 A surge current?
The peak clamping voltage (VC) of VGSOT15-HG3-08 is ≤28.8 V at 15.5 A (8/20 μs waveform), per its absolute maximum ratings table. At lower currents (e.g., 1 A), VC is ≤22.5 V. This clamping performance ensures protected ICs remain within safe operating voltage limits during IEC 61000-4-5 surge events. VGSOT15-HG3-08 achieves this with low dynamic impedance and optimized silicon geometry.
Does VGSOT15-HG3-08 support bidirectional ESD protection?
No, VGSOT15-HG3-08 is a unidirectional ESD protection diode. It clamps positive transients from the protected line (Pin 3) to ground (Pin 1) and conducts negative transients in forward bias toward ground - a behavior termed Bidirectional Asymmetrical (BiAs) mode. It does not provide symmetrical bidirectional clamping like a TVS array. VGSOT15-HG3-08 is intended for ground-referenced signal lines where polarity is known and controlled.
What is the capacitance of VGSOT15-HG3-08 at 15 V reverse bias?
At VR = 15 V and f = 1 MHz, the typical capacitance of VGSOT15-HG3-08 is 43 pF. At 0 V bias, capacitance is 100–120 pF. This voltage-dependent capacitance profile minimizes signal loading on high-speed lines while maintaining effective ESD suppression. The 43 pF value at VRWM ensures minimal impact on edge rates in 12 V industrial I/O and automotive sensor outputs. VGSOT15-HG3-08's low-bias capacitance supports USB 2.0 compliance.
