Product details
Overview
VBUS54GD-FBL-G3-08 from Vishay Semiconductors is a 4-line bidirectional ESD protection diode array in LLP2510-10M package, designed for high-speed data interfaces including USB 3.0, HDMI, DisplayPort, and Thunderbolt. It provides ±15 kV IEC 61000-4-2 contact/air discharge immunity, 0.3 pF inter-line capacitance, and clamps transients to ≤15 V at 3 A peak pulse current while operating up to 5.5 V DC.
For engineers reviewing the VBUS54GD-FBL-G3-08 datasheet, VBUS54GD-FBL-G3-08 pinout, VBUS54GD-FBL-G3-08 application, or VBUS54GD-FBL-G3-08 equivalent, this device delivers low-capacitance, flow-through layout compatibility, asymmetric bidirectional clamping, and MSL Level 1 solderability - critical for maintaining signal integrity on 480 Mbps to 1.65 Gbps differential data lines.
Technical Context
The VBUS54GD-FBL-G3-08 implements a Zener-based asymmetric bidirectional (BiAs) clamping architecture with matched D1+/D1− and D2+/D2− channel pairs. Its internal structure connects pins 3 and 8 to GND, uses pins 1/2/4/5 as active I/O terminals, and leaves pins 6/7/9/10 unconnected - enabling direct in-line placement without vias or trace discontinuities.
It achieves 0.6–0.75 pF line-to-ground capacitance at 1 MHz and 0 V bias, with only 0.3–0.4 pF between I/O lines, minimizing crosstalk and insertion loss. Clamping occurs at 9.1 V (typ.) for 1 A pulses and rises to 12–15 V at 3 A, while dynamic resistance remains ≤0.76 Ω under TLP stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Immunity | ±15 kV contact & air discharge per IEC 61000-4-2 - ensures robust handling in manufacturing and end-user environments |
| Clamping Voltage (IPPM = 3 A) | 12–15 V - limits transient overvoltage to safe levels for 5.5 V-rated interface ICs |
| Inter-Line Capacitance | 0.3–0.4 pF at 3.3 V - preserves signal rise/fall times and eye diagram integrity on USB 3.0/HDMI links |
| Reverse Standoff Voltage | 5.5 V - matches standard USB/HDMI supply rails without leakage-induced logic errors |
| Leakage Current | ≤0.1 μA at 5.5 V - prevents DC loading of high-impedance receiver inputs |
| Package | LLP2510-10M (2.5 × 1.0 × 0.55 mm, 0.6 mm max height) - enables ultra-thin PCB designs and automated optical inspection |
| Peak Pulse Power | 45 W per line (IEC 61000-4-5, 8/20 μs) - withstands surge events from cable coupling or board-level transients |
Pinout & Package
VBUS54GD-FBL-G3-08 uses the LLP2510-10M leadless plastic package (2.5 mm × 1.0 mm × 0.55 mm max), featuring a flow-through design optimized for high-speed differential traces. Pin 1 is marked by a dot; pins 3 and 8 are internally shorted GND terminals; pins 1/2 and 4/5 serve as matched D1+/D1− and D2+/D2− I/O pairs; pins 6/7/9/10 are NC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5 | Differential I/O (D1+, D1−, D2+, D2−) | Active ESD protection paths - placed inline with data lanes to minimize impedance discontinuity |
| 3, 8 | GND | Internally shorted ground reference - must be connected to system ground plane with low-inductance path |
| 6, 7, 9, 10 | No Connect (NC) | Unbonded die pads - no PCB routing or thermal relief required |
Key Features
| Feature | Design Value |
|---|---|
| Flow-through layout | Enables straight PCB trace routing across pins 1–2 and 4–5 - eliminates stubs, vias, or bends that degrade 1.65 Gbps HDMI signals |
| Asymmetric bidirectional clamping | Clamps negative transients below GND and positive transients above 5.5 V - protects both sides of differential receivers without biasing issues |
| 0.3 pF inter-line capacitance | Maintains <1% signal attenuation at 3 GHz - verified for HDMI 1.4 and USB 3.0 compliance |
| MSL Level 1 rating | Supports reflow up to 260 °C/10 s without preconditioning - simplifies SMT assembly and eliminates moisture bake steps |
| e3 matte tin termination | RoHS-compliant Sn plating with >1000-hr sulfur resistance - ensures long-term solder joint reliability in humid industrial enclosures |

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 inter-line capacitance; ±12 kV ESD rating; 1.6 mm × 1.6 mm X2SON package | Higher capacitance limits use to USB 2.0 or lower-speed HDMI; larger footprint consumes more board area | Select when cost sensitivity outweighs 0.2 pF capacitance advantage and board space permits larger package |
| ESD5451N | 0.35 pF inter-line capacitance; ±15 kV ESD; 2.0 mm × 1.25 mm XSON-10 package; 6.5 V VRWM | Slightly higher stand-off voltage suits 6 V auxiliary rails; different pinout requires layout revision | Choose for mixed-voltage systems needing 6.5 V tolerance, but verify GND pin mapping and thermal pad compatibility |
Compared with TPD4E05U06DQAR and ESD5451N, VBUS54GD-FBL-G3-08 offers the lowest inter-line capacitance (0.3 pF) and smallest footprint (2.5 × 1.0 mm) among 4-line ESD arrays, making it optimal for space-constrained, multi-gigabit interfaces where signal fidelity is non-negotiable.

FAQ
What is the maximum working voltage supported by VBUS54GD-FBL-G3-08?
The VBUS54GD-FBL-G3-08 has a reverse stand-off voltage (VRWM) of 5.5 V, meaning it reliably blocks voltages up to this level in normal operation without significant leakage. This matches standard USB 3.0 and HDMI supply rails. The device begins clamping at ~6.9 V breakdown and maintains safe operation up to its 125 °C junction temperature limit. VBUS54GD-FBL-G3-08 is not rated for continuous operation above 5.5 V DC.
Can VBUS54GD-FBL-G3-08 be used for single-ended signal lines like UART or I²C?
VBUS54GD-FBL-G3-08 is optimized for differential high-speed data lines (D1+/D1−, D2+/D2−) and relies on matched pair symmetry for minimal skew and crosstalk. Its 0.3 pF inter-line capacitance and asymmetric clamping are tailored for differential signaling. For single-ended interfaces such as UART or I²C, Vishay recommends dedicated single-line protectors like VBUS052CD-FAH, as VBUS54GD-FBL-G3-08's pinout and channel pairing do not align with typical single-ended routing.
Does VBUS54GD-FBL-G3-08 require external biasing or series resistors?
No, VBUS54GD-FBL-G3-08 operates passively with no external biasing or series components required. Its Zener-based clamping structure functions automatically during ESD events. The device is designed for direct in-line placement between connector and PHY, with pins 3 and 8 tied directly to a low-inductance ground plane. Series resistors would degrade signal integrity and are neither specified nor recommended in the official application schematics for USB 3.0 or HDMI.
How does the flow-through design of VBUS54GD-FBL-G3-08 improve signal integrity?
The flow-through design routes high-speed differential traces straight through pins 1→2 and 4→5 without vias, stubs, or layer transitions - preserving controlled impedance and minimizing reflections. Measured insertion loss remains <0.3 dB up to 3 GHz, and return loss exceeds 15 dB across the USB 3.0 and HDMI 1.4 bandwidth. This architecture directly addresses the 50 Ω surge impedance requirement of modern serial links, which VBUS54GD-FBL-G3-08 supports without compromising layout simplicity.
Is VBUS54GD-FBL-G3-08 compatible with lead-free reflow profiles?
Yes, VBUS54GD-FBL-G3-08 features e3 matte tin terminations and is qualified for lead-free reflow per J-STD-020. It supports peak temperatures up to 260 °C for 10 seconds at the terminals and carries MSL Level 1 rating - meaning it can be stored indefinitely at ambient conditions without baking. The LLP2510-10M package's low mass and uniform thermal response ensure reliable joint formation across all 10 terminals during standard Pb-free reflow cycles.
