Product details
Overview
VBUS03N1-DD1-G3-08 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) single-line ESD protection diode in DFN1006-2B package, designed for high-speed data lines. It provides ±16 kV IEC 61000-4-2 contact/air discharge immunity, 0.36 pF typical load capacitance, <0.1 μA reverse leakage at 3.3 V, and clamps transients to ≤21 V at 4 A peak pulse current - deployed in USB 3.0, HDMI, and Thunderbolt interfaces.
For engineers reviewing the VBUS03N1-DD1-G3-08 datasheet, VBUS03N1-DD1-G3-08 pinout, VBUS03N1-DD1-G3-08 application, or VBUS03N1-DD1-G3-08 equivalent, key selection criteria include ultra-low capacitance for signal integrity, AEC-Q101 qualification status, DFN1006-2B footprint compatibility, and ±3.3 V working voltage range in compact high-speed interface protection designs.
Technical Context
The VBUS03N1-DD1-G3-08 implements a symmetrical Zener-based clamping structure with matched forward/reverse breakdown characteristics (VBR = 7–10 V), enabling identical transient suppression for positive and negative ESD events on a single line. Its DFN1006-2B package delivers sub-0.5 mm height and minimal parasitic inductance, critical for preserving rise-time fidelity in >5 Gbps serial links.
It operates within ±3.3 V DC working range while maintaining <0.1 μA leakage and 0.36 pF capacitance at 0 V and 3.3 V bias - ensuring negligible loading on high-frequency signals. Clamping performance is validated per IEC 61000-4-5 (8/20 μs, 90 W peak power) and IEC 61000-4-2 (±16 kV), with dynamic resistance of 1.4 Ω measured via TLP.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±16 kV contact & air discharge (IEC 61000-4-2): ensures robust system-level ESD immunity without signal degradation. |

FAQ
What is the maximum operating temperature for VBUS03N1-DD1-G3-08?
The VBUS03N1-DD1-G3-08 has a junction temperature range of −55 °C to +150 °C, with storage temperature matching that span. This wide range supports deployment in under-hood automotive environments and thermally demanding industrial enclosures. The G3 suffix confirms AEC-Q101 qualification, meaning VBUS03N1-DD1-G3-08 undergoes stress testing across this full range per automotive reliability standards.
Does VBUS03N1-DD1-G3-08 require external biasing or control signals?
No, VBUS03N1-DD1-G3-08 is a passive, bidirectional Zener-based ESD suppressor with no external control pins or bias requirements. It operates solely between the protected signal line (terminal 1) and ground (terminal 2), clamping transients automatically when voltage exceeds ±7 V breakdown threshold. Its design eliminates complexity in high-speed routing where VBUS03N1-DD1-G3-08 is placed directly at the connector.
How does the 0.36 pF capacitance of VBUS03N1-DD1-G3-08 impact USB 3.0 signal integrity?
The 0.36 pF typical capacitance of VBUS03N1-DD1-G3-08 introduces negligible impedance drop above 5 GHz, preserving the 5 Gbps eye diagram and meeting USB-IF compliance margins for insertion loss and jitter. Measured at both 0 V and 3.3 V bias, this stable capacitance ensures consistent performance across operating conditions - a key reason VBUS03N1-DD1-G3-08 is selected for SuperSpeed lane protection.
Is VBUS03N1-DD1-G3-08 compatible with lead-free reflow processes?
Yes, VBUS03N1-DD1-G3-08 features e3 Sn-plated copper leads rated for peak reflow temperatures up to 260 °C, fully compliant with IPC/JEDEC J-STD-020 moisture sensitivity level 1. The DFN1006-2B package supports standard lead-free reflow profiles, and its tin finish enables automated optical inspection (AOI) of solder joints without requiring X-ray verification - simplifying VBUS03N1-DD1-G3-08 integration into high-volume manufacturing.
What is the clamping voltage of VBUS03N1-DD1-G3-08 under a 4 A ESD surge?
Under a 4 A peak pulse current (IPPM) per IEC 61000-4-5 (8/20 μs waveform), the VBUS03N1-DD1-G3-08 clamps to ≤21 V. This value is confirmed in the datasheet's Electrical Characteristics table and ensures downstream 3.3 V logic ICs remain within absolute maximum ratings. At lower currents (e.g., 1 A), clamping drops to ≤13 V - providing scalable protection aligned with VBUS03N1-DD1-G3-08's BiSy architecture.
