Product details
Overview
VBUS05N1-HD1-G3-08 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-ideal for USB 3.0 and HDMI interfaces.
For engineers reviewing the VBUS05N1-HD1-G3-08 datasheet, VBUS05N1-HD1-G3-08 pinout, VBUS05N1-HD1-G3-08 application, or VBUS05N1-HD1-G3-08 equivalent, key selection criteria include ultra-low capacitance for signal integrity, AEC-Q101 qualification option, compact 1.0 × 0.6 mm footprint, and verified clamping performance under IEC 61000-4-5 8/20 μs surge conditions.
Technical Context
The VBUS05N1-HD1-G3-08 implements a silicon avalanche diode structure optimized for fast transient response and minimal parasitic capacitance. Its DFN1006-2A package features short internal leads and exposed copper lead frame with e3 Sn plating, enabling low dynamic resistance (0.8 Ω typ.) and reliable AOI-verified solder joints.
This device operates as a grounded-cathode unidirectional clamp: pin 1 connects to the protected line, pin 2 to ground. It maintains <0.1 μA leakage at 5.5 V VRWM and achieves stable clamping down to -55 °C, supporting automotive and industrial environments where thermal robustness and low standby power are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 5.5 V - maximum continuous operating voltage before conduction begins; ensures no interference with 3.3 V or 5 V logic signaling |

| AEC-Q101 qualified variant available | Qualified per stress test standard for automotive electronics - supports infotainment and ADAS interface protection |
| e3 Sn-plated lead frame | Tin finish on exposed side walls - enables automated optical inspection (AOI) without X-ray for production traceability |
| Low dynamic resistance | 0.8 Ω typ. - minimizes voltage overshoot during sub-nanosecond ESD events (IEC 61000-4-2) |
Applications
| USB 3.0 Interface Protection | HDMI Signal Line Protection |
|---|---|
Use Scenario: Protecting SuperSpeed differential pairs (TX/RX) in laptop docking stations against user-handling ESD. IC Role / Device Role / Timing Role: Unidirectional transient voltage suppressor placed inline between connector and PHY IC. Use Value: 0.7 pF capacitance prevents eye diagram closure; ±16 kV contact discharge rating exceeds IEC 61000-4-2 Level 4 requirement. | Use Scenario: Shielding TMDS clock and data channels in flat-panel display controllers from cable-discharge events. IC Role / Device Role / Timing Role: Ground-referenced clamping diode on each TMDS+ line, with direct ground-plane connection.

| Automotive Infotainment Port | Industrial Camera Interface |
Use Scenario: ESD hardening of USB Type-C ports in vehicle head units exposed to dry-climate cabin environments. IC Role / Device Role / Timing Role: Single-line protection element mounted adjacent to connector, leveraging AEC-Q101-qualified variant. Use Value: -55 °C to +150 °C operation supports extended temperature cycling; 5.5 V VRWM matches 5 V supply rails in automotive USB hubs. | Use Scenario: Safeguarding MIPI D-PHY lanes in machine vision cameras connected via flexible cables prone to triboelectric discharge. IC Role / Device Role / Timing Role: Point-of-entry protection on each high-speed data lane before serializer IC input. Use Value: 0.4 mm profile allows placement in tight board spaces near connectors; low leakage (<0.1 μA) avoids DC bias shift in analog front ends. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A-E3/57T | DO-214AC package (4.5 × 2.7 mm); 5.0 V VRWM; 150 pF capacitance | Designed for lower-speed power/data lines (≤100 Mbps); unsuitable for USB 3.0/HDMI | Select only for cost-sensitive, non-high-speed applications where board space permits larger footprint |
| TPD4E001DPYR | 4-channel array in DQFN10 package; 0.9 pF per channel; 5.5 V VRWM | Offers multi-line integration but higher per-line capacitance than VBUS05N1-HD1-G3-08 | Prefer when protecting multiple adjacent lines (e.g., full USB 3.0 differential pair + power) with shared ground |
Compared with SMAJ5.0A-E3/57T and TPD4E001DPYR, the VBUS05N1-HD1-G3-08 uniquely balances ultra-low capacitance (0.7 pF), miniature DFN1006-2A size, and single-line optimization-making it the preferred choice for space-constrained, high-bandwidth interfaces requiring minimal signal loading.

FAQ
What is the maximum working voltage supported by VBUS05N1-HD1-G3-08?
The VBUS05N1-HD1-G3-08 has a reverse stand-off voltage (VRWM) of 5.5 V, meaning it can safely operate up to this DC or peak AC voltage without significant leakage. This rating ensures compatibility with standard 3.3 V and 5 V logic systems while maintaining high isolation below its breakdown threshold of 7.0–9.0 V.
Does VBUS05N1-HD1-G3-08 meet automotive qualification standards?
Yes-the base VBUS05N1-HD1 device is offered in an AEC-Q101 qualified version (e.g., VBUS05N1-HD1HG3-08). While VBUS05N1-HD1-G3-08 itself is RoHS-compliant and built on the same die, qualification status depends on the specific ordering code suffix; always verify the environmental and quality code (e.g., "H") when selecting for automotive use.
How does the 0.7 pF capacitance of VBUS05N1-HD1-G3-08 impact USB 3.0 signal integrity?
The 0.7 pF typical load capacitance of VBUS05N1-HD1-G3-08 introduces negligible impedance change above 1 GHz, preserving USB 3.0 Gen 1 eye diagrams and jitter budgets. Measured insertion loss remains below 0.5 dB up to 5 GHz, ensuring compliance with SuperSpeed signaling requirements without equalization overhead.
Can VBUS05N1-HD1-G3-08 be used in bidirectional signal paths?
No-VBUS05N1-HD1-G3-08 is a unidirectional ESD protector with anode-to-cathode polarity. It conducts only during positive transients on the line (pin 1 → pin 2). For bidirectional lines like USB 2.0 D+/D−, a symmetric dual-diode array or dedicated bidirectional device is required instead.
What is the thermal performance limit of VBUS05N1-HD1-G3-08 during repeated ESD strikes?
VBUS05N1-HD1-G3-08 is rated for junction temperatures from -55 °C to +150 °C. Under IEC 61000-4-2 testing (10 pulses), self-heating is negligible due to nanosecond-scale energy deposition. Sustained operation at +150 °C ambient is validated, making it suitable for engine bay or enclosed industrial enclosures without derating.
