Product details
Overview
VBUS05B1-SD0HG4-08 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) single-line ESD protection diode in a CLP0603-2L silicon package, rated for ±5.5 V working voltage, 0.29 pF typical load capacitance, <0.05 μA reverse leakage, and ±16 kV IEC 61000-4-2 contact/air discharge immunity-designed for high-speed USB 3.0, HDMI, and Thunderbolt data line protection.
For engineers reviewing the VBUS05B1-SD0HG4-08 datasheet, VBUS05B1-SD0HG4-08 pinout, VBUS05B1-SD0HG4-08 application, or VBUS05B1-SD0HG4-08 equivalent, key selection criteria include ultra-low capacitance (<0.4 pF), sub-0.3 mm profile, IEC 61000-4-5 compliant 2.5 A peak pulse current, and CLP0603-2L footprint compatibility with high-density PCB layouts.
Technical Context
The VBUS05B1-SD0HG4-08 implements a symmetrical clamping structure that responds identically to positive and negative transients, enabling robust bidirectional protection without polarity dependency. Its low dynamic resistance (1.14 Ω typ.) and fast TLP response (100 ns pulse width) ensure minimal overshoot during ESD events.
Designed for signal integrity preservation, it maintains <0.29 pF capacitance at both 0 V and 3.3 V bias, and exhibits insertion loss <0.5 dB up to 10 GHz-critical for preserving eye diagram integrity on 5 Gbps+ serial links.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | ±5.5 V - defines maximum continuous DC or AC signal swing before leakage rises or clamping initiates |
| Load Capacitance | 0.29 pF typ. at 1 MHz and 0 V - ensures negligible signal distortion on USB 3.0/Thunderbolt differential pairs |
| ESD Rating | ±16 kV contact / ±16 kV air per IEC 61000-4-2 - meets industrial and portable device immunity requirements |
| Peak Pulse Current | 2.5 A per IEC 61000-4-5 (8/20 μs) - sustains surge energy without thermal failure |
| Reverse Leakage | <0.05 μA at 5.5 V - avoids signal attenuation or DC offset in high-impedance receivers |
| Clamping Voltage | 15 V max at 2.5 A - limits transient overvoltage to safe levels for downstream PHY ICs |
| Package | CLP0603-2L - 0.6 × 0.3 mm, 0.27 mm height, compatible with standard 0201 reflow profiles |
Pinout & Package
CLP0603-2L is a 2-terminal leadless chip-scale package with exposed die pad and no internal leads; terminals are co-planar, symmetric, and non-polarized. Pin 1 marking is indicated by an open circle adjacent to one terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Signal Line Anode/Cathode | Bidirectional connection point - functions as anode for negative transients and cathode for positive transients |
| Terminal 2 | Ground Reference | Low-inductance path to system ground plane; requires direct thermal and electrical connection to ground pour |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Symmetrical Clamping | Equal clamping behavior for ± transients eliminates need for polarity-aware layout or orientation checks |
| Ultra-Low Capacitance | 0.29 pF typ. preserves signal rise/fall times and minimizes jitter on >5 Gbps serial interfaces |
| Sub-0.3 mm Profile | 0.27 mm max height enables use under connectors and in ultra-thin mobile PCB stacks |
| Gold-Plated Termination | Au (e4) plating ensures solderability stability and intermetallic reliability across multiple reflow cycles |
| Low Dynamic Resistance | 1.14 Ω typ. reduces clamping voltage overshoot and improves energy dissipation linearity |
Applications
| USB 3.0 SuperSpeed Interface | HDMI 2.0 Differential Pairs |
|---|---|
Use Scenario: Protecting TX/RX differential lanes between host controller and Type-A/B receptacle against ESD during hot-plug events. IC Role / Device Role / Timing Role: Passive clamping diode placed within 3 mm of connector, shunting transients directly to chassis ground.

IC Role / Device Role / Timing Role: Single-line BiSy protector per differential pair, mounted adjacent to HDMI connector pins. Use Value: Enables full compliance with IEC 61000-4-2 Level 4 while adding <0.02 dB insertion loss at 3 GHz. |
| Thunderbolt 3 Host Port | PCIe Gen3 SerDes Lines |
Use Scenario: ESD hardening of dual-lane Thunderbolt 3 interface (TX/RX + CC lines) on laptop docking station PCBs. IC Role / Device Role / Timing Role: One VBUS05B1-SD0HG4-08 per signal line, routed with matched length and minimal stub. Use Value: Delivers 0.29 pF capacitance at 3.3 V bias-critical for maintaining 10 Gbps signal integrity and passing USB-IF compliance tests. | Use Scenario: Protecting PCIe Gen3 reference clock and high-speed data lanes in embedded server mezzanine cards. IC Role / Device Role / Timing Role: Point-of-entry protection on edge connectors, placed before series AC coupling capacitors. Use Value: Sub-0.3 mm height avoids interference with adjacent BGA packages; 2.5 A IEC 61000-4-5 rating handles board-level surge coupling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E05U06DQAR | 0.5 pF typ. capacitance; quad-channel; SOT-563 package; higher 1.2 mm height | Requires more board area; less suitable for ultra-thin or space-constrained USB/HDMI designs | Select when multi-line integration outweighs capacitance penalty and height constraints |
| ESD56081D05 | 0.35 pF typ.; same CLP0603-2L footprint; lower 1.8 A IEC 61000-4-5 rating | Marginally lower surge handling; may require derating in harsh industrial environments | Select when cost sensitivity dominates and 1.8 A peak pulse current suffices for target application class |
Compared with TPD4E05U06DQAR and ESD56081D05, the VBUS05B1-SD0HG4-08 delivers the lowest verified capacitance (0.29 pF) in the CLP0603-2L form factor, enabling highest-frequency signal integrity retention-making it optimal for next-generation 10+ Gbps interfaces where every 0.05 pF impacts eye margin.
