Product details
Overview
VBUS03N1-HD1HG3-08 from Vishay Semiconductors is a unidirectional ESD protection diode in DFN1006-2A package, designed for single-line high-speed data lines with 3.3 V working voltage, 0.7 pF typical load capacitance, <0.1 μA reverse leakage, and ±16 kV IEC 61000-4-2 ESD immunity. It serves as a low-inductance clamping device on interfaces such as USB 3.0 and HDMI.
For engineers reviewing the VBUS03N1-HD1HG3-08 datasheet, VBUS03N1-HD1HG3-08 pinout, VBUS03N1-HD1HG3-08 application, or VBUS03N1-HD1HG3-08 equivalent, key selection criteria include ultra-low capacitance for signal integrity, AEC-Q101 qualification status, DFN1006-2A footprint compatibility, and clamping performance at 4 A peak pulse current.
Technical Context
The VBUS03N1-HD1HG3-08 implements a single-channel unidirectional TVS structure optimized for fast transient suppression on high-speed signal paths. Its DFN1006-2A package delivers minimal parasitic inductance and 0.7 pF capacitance at 0 V bias, enabling use up to multi-gigabit data rates without signal degradation.
It operates within a 3.3 V reverse stand-off range (VRWM), clamps transients to ≤15 V at 4 A (IEC 61000-4-5), and maintains <0.1 μA leakage at rated voltage. The device is qualified to AEC-Q101 and features Sn-plated exposed lead frame sidewalls for AOI-compatible solder joint inspection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Protection Type | Unidirectional - protects only against positive transients to ground; requires correct polarity placement on signal line. |
| Reverse Stand-off Voltage (VRWM) | 3.3 V - maximum continuous operating voltage before conduction begins; matches standard 3.3 V I/O rails. |
| Clamping Voltage (VC @ 4 A) | 13–15 V - limits voltage seen by downstream IC during 8/20 μs surge, protecting 3.3 V logic inputs. |
| Load Capacitance (CD) | 0.7 pF typ. @ 1 MHz - ensures minimal signal distortion on USB 3.0, HDMI, and Thunderbolt data lanes. |
| ESD Immunity | ±16 kV contact/air discharge (IEC 61000-4-2) - meets industrial and automotive system-level ESD requirements. |
| Peak Pulse Power (PPP) | 60 W @ 8/20 μs - sustains short-duration surges without thermal failure under defined test conditions. |
| Operating Temperature | −55 °C to +150 °C - supports under-hood automotive and industrial environments with extended junction range. |
Pinout & Package
VBUS03N1-HD1HG3-08 is housed in a DFN1006-2A surface-mount package measuring 1.0 mm × 0.6 mm × 0.45 mm max, with cathode marked by a bar on the top surface. The package uses copper lead frame with e3 Sn plating on exposed sidewalls for optical solder inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Connected to protected signal line (e.g., USB D+); forward-biased during negative ESD events. |
| Pin 2 | Cathode | Connected to system ground; provides low-impedance path for clamped ESD current to return. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 0.7 pF typ. enables use on >5 Gbps serial links without measurable eye diagram degradation. |
| AEC-Q101 qualification | Validated for automotive applications including infotainment and ADAS data interfaces. |
| Low-profile package | 0.45 mm max height allows placement beneath connectors and in space-constrained PCB layouts. |
| Sn-plated sidewalls | Enables automated optical inspection (AOI) of solder joints without requiring X-ray. |
| Low leakage current | <0.1 μA at 3.3 V ensures negligible power drain on battery-powered high-speed ports. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ3.3A | DO-214AC package; 300 pF capacitance; 14.5 V clamping @ 12.3 A; not suitable for >100 Mbps signals. | Designed for power rail or low-speed I/O protection; incompatible with USB/HDMI due to excessive capacitance. | Select only for cost-sensitive, non-high-speed applications where board space and signal integrity are secondary. |
| TPD4E001DPYR | 4-channel array in DFN1006-6; 0.6 pF per line; 3.3 V VRWM; ±12 kV ESD rating; no AEC-Q101 qualification. | Multi-line solution for compact routing; lower ESD rating limits use in harsh automotive environments. | Prefer when protecting multiple lines simultaneously on space-constrained boards, but verify system-level ESD compliance separately. |
Compared with SMAJ3.3A and TPD4E001DPYR, VBUS03N1-HD1HG3-08 uniquely balances ultra-low capacitance, AEC-Q101 qualification, and single-line optimization-making it the only choice for automotive-grade, high-speed serial interface protection where layout density and signal fidelity are critical.

FAQ
What is the maximum operating temperature range for VBUS03N1-HD1HG3-08?
The VBUS03N1-HD1HG3-08 has a specified junction temperature range of −55 °C to +150 °C, validated per AEC-Q101 stress testing. This enables deployment in under-hood automotive modules and industrial edge devices where ambient temperatures exceed 105 °C. The DFN1006-2A package's low thermal resistance supports reliable operation at the upper limit when properly mounted on thermally enhanced PCBs.
Is VBUS03N1-HD1HG3-08 pin-compatible with other Vishay DFN1006-2A ESD diodes?
Yes, VBUS03N1-HD1HG3-08 shares identical DFN1006-2A mechanical dimensions and pinout (anode on Pin 1, cathode on Pin 2) with Vishay's VBUS03M1-HD1 and VBUS05M1-HD1 variants. However, electrical parameters differ: VBUS03N1-HD1HG3-08 is rated for 3.3 V VRWM and 0.7 pF capacitance, whereas VBUS05M1-HD1 targets 5.0 V rails with higher capacitance. Always verify VRWM and CD values before substitution.
Does VBUS03N1-HD1HG3-08 support bidirectional ESD protection?
No, VBUS03N1-HD1HG3-08 is strictly unidirectional-it conducts only when the anode is driven positive relative to the cathode. For bidirectional protection (e.g., AC-coupled lines), two VBUS03N1-HD1HG3-08 devices must be placed back-to-back, or a dedicated bidirectional part like VBUS03M1-HD1 should be selected. Using VBUS03N1-HD1HG3-08 on bidirectional signals without proper polarity alignment risks permanent conduction or failure.
What is the clamping voltage of VBUS03N1-HD1HG3-08 at 1 A and 4 A peak pulse current?
Per the official Vishay datasheet (Doc. #86205, Rev. 1.4), VBUS03N1-HD1HG3-08 exhibits a typical clamping voltage of 9.5 V at 1 A IPP and 13 V at 4 A IPP (IEC 61000-4-5, 8/20 μs waveform). These values ensure downstream 3.3 V logic remains within safe operating limits during surge events, with margin below the 15 V absolute maximum rating of most interface transceivers.
Can VBUS03N1-HD1HG3-08 be used on 5 V logic lines?
No-VBUS03N1-HD1HG3-08 has a 3.3 V reverse stand-off voltage (VRWM) and begins conducting significantly above that threshold. Applying it to a 5 V line would cause excessive leakage and potential thermal runaway. For 5 V applications, Vishay recommends VBUS05M1-HD1 (5.0 V VRWM) or similar 5 V-rated ESD suppressors. Always match VRWM to the nominal I/O voltage of the protected line.
