Product details
Overview
VBUS05N1-HD1HG3-08 from Vishay Semiconductors is a unidirectional ESD protection diode in DFN1006-2A package, designed for single-line high-speed data line protection. It delivers 5.5 V reverse stand-off voltage, 0.7 pF typical load capacitance, ±16 kV IEC 61000-4-2 ESD immunity, and clamps transients to ≤15 V at 4 A peak pulse current. It is used in USB 3.0, HDMI, and Thunderbolt interfaces where ultra-low capacitance and minimal signal distortion are critical.
For engineers reviewing the VBUS05N1-HD1HG3-08 datasheet, VBUS05N1-HD1HG3-08 pinout, VBUS05N1-HD1HG3-08 application, or VBUS05N1-HD1HG3-08 equivalent, key selection criteria include clamping voltage at 4 A, leakage current ≤0.1 μA at 5.5 V, DFN1006-2A footprint compatibility, AEC-Q101 qualification status, and suitability for <1 Gbps differential signaling paths.
Technical Context
The VBUS05N1-HD1HG3-08 implements a silicon avalanche diode structure optimized for fast transient response with low dynamic resistance (0.8 Ω typ.) and minimal overshoot. Its DFN1006-2A package features short internal leads and exposed copper lead frame, enabling sub-0.5 mm height and low parasitic inductance essential for ESD clamping of nanosecond-scale events.
It operates as a grounded-cathode unidirectional clamp: pin 1 connects to the protected signal line, pin 2 to system ground. The device remains non-conductive below 5.5 V VRWM but triggers sharply at ~7.8 V breakdown (typ.), limiting voltage excursions during ±16 kV contact/air discharge per IEC 61000-4-2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 5.5 V - Maximum continuous working voltage before conduction; ensures no interference with 3.3 V or 5 V logic signaling. |
| Clamping Voltage (IPPM = 4 A) | 13–15 V - Peak voltage seen by protected IC during worst-case 8/20 μs surge; limits stress on downstream PHY transceivers. |
| Load Capacitance | 0.7 pF typ. at 0 V - Enables use in >5 Gbps serial links (e.g., USB 3.0 Gen 1) without measurable signal integrity degradation. |
| ESD Immunity | ±16 kV contact / ±16 kV air - Meets IEC 61000-4-2 Level 4, suitable for consumer and automotive infotainment ports. |
| Leakage Current | ≤0.1 μA at 5.5 V - Prevents DC loading of high-impedance data lines and preserves signal threshold margins. |
| Package | DFN1006-2A - 1.0 × 0.6 × 0.4 mm outline with cathode marking; compatible with standard 0201 reflow profiles and AOI inspection. |
| Operating Temperature | −55 °C to +150 °C - Supports under-hood automotive and industrial edge computing deployments. |
Pinout & Package
VBUS05N1-HD1HG3-08 uses the DFN1006-2A surface-mount package: 1.0 mm × 0.6 mm body, 0.4 mm max height, tin-plated copper lead frame with e3 Sn finish. Cathode is marked by a bar on the top surface. Pin 1 is the anode (signal line connection), Pin 2 is the cathode (ground connection).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Connects to protected high-speed data line (e.g., USB D+, HDMI TMDS+); carries transient current into the diode during positive ESD events. |
| Pin 2 | Cathode | Connected directly to system ground plane; provides low-inductance return path for ESD current, minimizing ground bounce. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 0.7 pF typ. - Preserves signal rise/fall times and eye diagram integrity in multi-Gbps interfaces without equalization overhead. |
| AEC-Q101 qualified option | Available in -HG3 variant - Confirms reliability for automotive infotainment and ADAS camera links per stress-test requirements. |
| Low-profile DFN package | 0.4 mm max height - Enables routing beneath fine-pitch BGAs and supports ultra-thin mobile PCB stack-ups. |
| e3 Sn termination | Tin-plated side walls - Allows automated optical inspection (AOI) of solder joints without X-ray, reducing manufacturing cost and cycle time. |
| Low dynamic resistance | 0.8 Ω typ. - Reduces clamping voltage overshoot during fast TLP pulses, improving protection margin for sensitive SerDes receivers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD1E05U06DPYR | 0.65 pF typ. capacitance; 5.5 V VRWM; ±12 kV IEC 61000-4-2; SOD-523 package (1.2 × 0.8 mm) | Larger footprint; lower ESD rating; not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification and 4 mm² board area is available. |
| SMAJ5.0A | 5.0 V VRWM; 600 W peak power; DO-214AC package; 100 pF capacitance | Unsuitable for >100 Mbps signals due to high capacitance; intended for power rail, not data line protection | Use only for low-speed I/O or supply rail clamping-not a functional substitute for VBUS05N1-HD1HG3-08 in high-speed data paths. |
Compared with TPD1E05U06DPYR and SMAJ5.0A, VBUS05N1-HD1HG3-08 uniquely combines AEC-Q101 qualification, 0.7 pF capacitance, and ±16 kV ESD rating in a 0.6 mm² DFN1006-2A package-making it the only viable choice for space-constrained automotive or premium consumer high-speed interface protection.

FAQ
What is the maximum clamping voltage of the VBUS05N1-HD1HG3-08 at 4 A peak pulse current?
The VBUS05N1-HD1HG3-08 exhibits a reverse clamping voltage of 13–15 V at IPPM = 4 A, measured per IEC 61000-4-5 (8/20 μs waveform). This value ensures downstream ICs with 16 V HBM ESD tolerance remain within safe operating limits during surge events. The clamping performance is validated across −55 °C to +125 °C ambient conditions.
Does the VBUS05N1-HD1HG3-08 support automotive applications?
Yes, the VBUS05N1-HD1HG3-08 is offered in an AEC-Q101 qualified version (denoted by "H" in the ordering code), making it suitable for automotive infotainment, ADAS camera links, and telematics modules. Its −55 °C to +150 °C operating junction temperature range and robust ±16 kV ESD immunity meet stringent automotive environmental and reliability requirements.
How does the 0.7 pF capacitance of the VBUS05N1-HD1HG3-08 impact high-speed signal integrity?
The 0.7 pF typical load capacitance of the VBUS05N1-HD1HG3-08 introduces negligible impedance mismatch on 50 Ω or 100 Ω differential traces, preserving eye diagrams up to 5 Gbps (USB 3.0 Gen 1). At 3.3 V bias, capacitance remains stable at 0.7 pF, avoiding frequency-dependent attenuation that could degrade jitter or bit-error rate in HDMI or Thunderbolt links.
What is the package size and soldering profile for the VBUS05N1-HD1HG3-08?
The VBUS05N1-HD1HG3-08 uses the DFN1006-2A package: 1.0 mm × 0.6 mm × 0.4 mm max. It supports standard lead-free reflow with peak temperature ≤260 °C (per J-STD-020). The e3 Sn-plated copper lead frame enables AOI-compatible solder joint inspection without X-ray, simplifying high-volume manufacturing validation.
Can the VBUS05N1-HD1HG3-08 be used for bidirectional signal lines like USB 2.0 D+ and D−?
No-the VBUS05N1-HD1HG3-08 is unidirectional and protects only positive transients relative to ground. For bidirectional lines such as USB 2.0, a dual-channel or bidirectional ESD diode (e.g., VBUS05M1-SD0) is required. Using VBUS05N1-HD1HG3-08 on bidirectional lines would leave negative ESD events unprotected, risking IC damage.
