Product details
Overview
VBUS03N1-HD1-G3-08 from Vishay Semiconductors is a unidirectional ESD protection diode in DFN1006-2A package, designed for single-line high-speed data lines. It provides ±16 kV IEC 61000-4-2 ESD immunity, 0.7 pF typical load capacitance, and 3.3 V reverse stand-off voltage, enabling use in USB 3.0, HDMI, and Thunderbolt interfaces.
For engineers reviewing the VBUS03N1-HD1-G3-08 datasheet, VBUS03N1-HD1-G3-08 pinout, VBUS03N1-HD1-G3-08 application, or VBUS03N1-HD1-G3-08 equivalent, key selection criteria include ultra-low capacitance, AEC-Q101 qualification option, clamping performance at 4 A peak pulse current, and compatibility with automated optical inspection due to e3 Sn plating.
Technical Context
The VBUS03N1-HD1-G3-08 operates as a unidirectional transient voltage suppressor, clamping positive overvoltage transients to ground while blocking reverse leakage below 0.1 μA at 3.3 V. Its DFN1006-2A footprint minimizes parasitic inductance, enabling fast response to ESD events without signal distortion.
It meets IEC 61000-4-2 (±16 kV contact/air) and IEC 61000-4-5 (4 A, 8/20 μs) standards, with a dynamic resistance of 0.8 Ω and clamping voltage of 13 V at 4 A. The device is rated for junction temperatures from –55 °C to +150 °C and supports reflow soldering up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±16 kV contact & air discharge per IEC 61000-4-2 - ensures robust system-level ESD survivability in consumer and automotive ports |
| Load Capacitance | 0.7 pF typ. at 0 V and 1 MHz - preserves signal integrity on >5 Gbps differential links like USB 3.0 Gen1 |

Applications
| USB 3.0 SuperSpeed Interface | HDMI 2.0 Data Channel |
|---|---|
Use Scenario: Protecting differential TX/RX pairs in host/device USB 3.0 ports against ESD events during hot-plug insertion. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed between signal line and ground, operating outside signal path during normal operation. Use Value: 0.7 pF capacitance prevents eye diagram closure; ±16 kV rating exceeds USB-IF compliance requirement for external ports. | Use Scenario: Safeguarding TMDS clock and data lanes in HDMI 2.0 source/sink devices exposed to user-handled cables. IC Role / Device Role / Timing Role: Single-line ESD suppressor per lane, leveraging low dynamic resistance (0.8 Ω) to minimize clamping delay. Use Value: Clamps transients within 1 ns, preserving 6 Gbps data rate timing margins and avoiding bit errors. |
| Thunderbolt™ 3 Host Port | Automotive Infotainment Display Link |
Use Scenario: Shielding bidirectional high-speed lanes (TX/RX) in Thunderbolt 3 controller I/O where space constraints limit discrete protection options. IC Role / Device Role / Timing Role: Per-lane unidirectional TVS diode with 3.3 V VRWM aligned to VCCIO rail, minimizing standby power loss. Use Value: 0.1 μA leakage avoids cumulative current draw across 4+ lanes; DFN1006-2A allows routing under connector footprint. | Use Scenario: Protecting LVDS or FPD-Link III video data lines between head unit and display in vehicles subject to ISO 10605 ESD stress. IC Role / Device Role / Timing Role: AEC-Q101-qualified variant used per differential pair to meet automotive EMC requirements.

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; 12.3 V clamping at 12.5 A | Designed for lower-speed, higher-power surge protection (e.g., power rails), not high-speed data lines | Select only if signal bandwidth < 100 MHz and board space permits larger footprint |
| TPD1E05U06DPYR | 0.45 pF typ. capacitance; 5.5 V VRWM; 3-pin SOT-563 package with common-anode dual-channel configuration | Supports dual-line protection in same footprint but requires layout revision for shared anode routing | Choose when protecting two adjacent lines (e.g., USB D+/D–) with tighter capacitance budget |
Compared with SMAJ3.3A and TPD1E05U06DPYR, the VBUS03N1-HD1-G3-08 uniquely balances sub-1 pF capacitance, 3.3 V stand-off, and DFN1006-2A size for single-line high-speed interfaces-making it optimal for space-constrained USB/HDMI designs where signal fidelity is critical.

FAQ
What is the maximum operating temperature range for the VBUS03N1-HD1-G3-08?
The VBUS03N1-HD1-G3-08 has a specified junction temperature range of –55 °C to +150 °C and a storage temperature range of –65 °C to +150 °C. This wide thermal capability supports deployment in harsh environments such as automotive under-hood or industrial edge computing enclosures where ambient temperatures exceed 85 °C. The device maintains its 0.7 pF capacitance and ±16 kV ESD rating across this full range.
Does the VBUS03N1-HD1-G3-08 support AEC-Q101 qualification?
Yes, the base part VBUS03N1-HD1 is AEC-Q101 qualified; the suffix "-G3-08" denotes RoHS-compliant, lead-free, green packaging with 10 k per 7″ reel. Customers requiring automotive-grade assurance should specify the AEC-Q101 variant (e.g., VBUS03N1-HD1HG3-08) which undergoes stress testing per AEC-Q101-004 and -011 standards. The VBUS03N1-HD1-G3-08 itself is not automatically qualified unless ordered with the "H" environmental code.
How does the clamping behavior of VBUS03N1-HD1-G3-08 compare at 1 A versus 4 A peak pulse current?
At 1 A IPP, the VBUS03N1-HD1-G3-08 clamps to 9.5 V typical; at 4 A IPP (its maximum rated pulse), clamping rises to 13 V typical. This 3.5 V increase reflects inherent dynamic resistance (0.8 Ω), confirming predictable, linear voltage rise under stress. Designers must ensure downstream ICs tolerate ≤13 V transient exposure. The VBUS03N1-HD1-G3-08 datasheet validates this behavior via TLP and IEC 61000-4-5 waveforms.
Can VBUS03N1-HD1-G3-08 be used for bidirectional signal lines like USB 2.0 D+ and D–?
No - the VBUS03N1-HD1-G3-08 is unidirectional and protects only positive transients on the anode-to-ground path. For bidirectional lines such as USB 2.0, a symmetric dual-diode array (e.g., VBUS05M1-03-G3) or separate anode/cathode configurations are required. Using VBUS03N1-HD1-G3-08 on a bidirectional line would leave negative transients unprotected and risk damage during ESD events.
What is the significance of the "e3" marking on VBUS03N1-HD1-G3-08?
The "e3" designation indicates Sn (tin) plating on the exposed side walls of the DFN1006-2A lead frame, compliant with JEDEC J-STD-609. This enables automated optical inspection (AOI) of solder joints without X-ray, reducing manufacturing cost and cycle time. The VBUS03N1-HD1-G3-08's e3 finish also supports Pb-free reflow profiles up to 260 °C peak and eliminates halogenated flux residue concerns in high-reliability assembly.
