Product details
Overview
VBUS05N1-DD1HG3-08 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) ESD protection diode in DFN1006-2B package, designed for single-line high-speed data line protection. It delivers ±16 kV IEC 61000-4-2 contact/air discharge immunity, ultra-low 0.36 pF typical load capacitance, <0.1 μA reverse leakage at 5.5 V, and clamps transients to ≤21 V at 4 A peak pulse current. It is used in USB 3.0, HDMI, and Thunderbolt interfaces where signal integrity and ESD robustness are critical.
For engineers reviewing the VBUS05N1-DD1HG3-08 datasheet, VBUS05N1-DD1HG3-08 pinout, VBUS05N1-DD1HG3-08 application, or VBUS05N1-DD1HG3-08 equivalent, key selection criteria include clamping voltage under 4 A, sub-0.4 pF capacitance at 1 MHz and 0 V bias, AEC-Q101 qualification status, DFN1006-2B footprint compatibility, and ±5.5 V working range compliance.
Technical Context
The VBUS05N1-DD1HG3-08 implements a symmetrical Zener-based clamping structure optimized for bidirectional transient suppression on high-speed signal lines. Its low dynamic resistance (1.4 Ω typ.) and minimal parasitic inductance-enabled by the DFN1006-2B's short internal leads-ensure fast response (<1 ns rise time) and tight clamping with low overshoot during ESD events.
It operates within a ±5.5 V DC working range and maintains stable capacitance (0.36 pF typ.) across 0–3.3 V reverse bias, enabling transparent integration into 3.3 V and 5 V data paths without signal degradation. The device is qualified to AEC-Q101 and features Sn (e3) plating for AOI-compatible solder joint inspection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J5.0A-Q | DO-214AC package (4.5 × 3.3 mm); 5.0 V VRWM; 12.5 V VC @ 1 A; 150 pF CD | Higher capacitance and larger footprint - unsuitable for >1 Gbps data lines | Select only for low-speed analog/sensor lines where size and capacitance are non-critical |

FAQ
What is the maximum clamping voltage of VBUS05N1-DD1HG3-08 under IEC 61000-4-5 surge conditions?
The VBUS05N1-DD1HG3-08 exhibits a maximum clamping voltage of 21 V at 4 A peak pulse current (IPPM), measured per IEC 61000-4-5 (8/20 μs waveform). This value ensures downstream ICs such as USB 3.0 PHYs remain within absolute maximum ratings during surge events. The clamping performance is verified across temperature and process variation, with typical VC at 18 V under the same conditions.
Is VBUS05N1-DD1HG3-08 qualified for automotive applications?
Yes, VBUS05N1-DD1HG3-08 is AEC-Q101 qualified, confirming its suitability for automotive use cases including infotainment USB-C ports and ADAS camera data links. The qualification covers temperature cycling, mechanical shock, humidity testing, and ESD robustness - all performed on the exact DFN1006-2B packaged VBUS05N1-DD1HG3-08 device.
What is the load capacitance of VBUS05N1-DD1HG3-08 at 3.3 V bias?
The load capacitance of VBUS05N1-DD1HG3-08 is 0.36 pF typical at 3.3 V reverse bias and 1 MHz, matching its 0 V value. This voltage-invariant capacitance is confirmed in the manufacturer's Typical Characteristics (Fig. 3) and ensures consistent signal integrity across operating rail voltages in 3.3 V systems like HDMI TMDS or USB 3.0 receivers.
Does VBUS05N1-DD1HG3-08 support bidirectional ESD protection without polarity concerns?
Yes, VBUS05N1-DD1HG3-08 is a bidirectional symmetrical (BiSy) device with matched positive and negative breakdown characteristics (VBR = 7–10 V both polarities). Its symmetrical Zener structure eliminates orientation sensitivity during placement - Pin 1 connects to the signal line and Pin 2 to ground regardless of DC bias direction, simplifying layout and reducing assembly errors.
What is the thermal resistance (RθJA) of VBUS05N1-DD1HG3-08 in standard PCB layout?
The datasheet does not specify RθJA for VBUS05N1-DD1HG3-08, as its power dissipation during ESD events is transient and non-continuous. Under IEC 61000-4-2, peak pulse power reaches 90 W for <100 ns, resulting in negligible average heating. Junction temperature remains within −55 °C to +150 °C limits even under repeated strikes, validated per AEC-Q101 thermal stress testing protocols.
