Product details
Overview
VBUS054B-HS3-GS08 from Vishay Semiconductors is a 4-line bidirectional ESD protection diode array in LLP75-6A package, designed for high-speed USB 2.0 data lines (D1+, D1−, D2+, D2−) and VBUS supply line. It delivers ±15 kV IEC 61000-4-2 contact/air discharge immunity, 0.8 pF typical line-to-ground capacitance, and clamps transients to ≤15 V at 3 A pulse on signal paths.
For engineers reviewing the VBUS054B-HS3-GS08 datasheet, VBUS054B-HS3-GS08 pinout, VBUS054B-HS3-GS08 application, or VBUS054B-HS3-GS08 equivalent, key selection criteria include low-capacitance ESD protection for USB 2.0 compliance, asymmetric bidirectional clamping behavior, and MSL Level 1 solderability for high-reliability assembly.
Technical Context
The VBUS054B-HS3-GS08 implements a BiAs (Bidirectional Asymmetrical) architecture: four low-capacitance PN diodes protect signal lines (pins 1,3,4,6 ↔ pin 2), while a dedicated Zener/avalanche diode protects the VBUS supply line (pin 5 ↔ pin 2). This enables independent clamping thresholds-7.9 V typ. breakdown on signal paths vs. 7.1 V typ. on VBUS-with distinct forward/reverse conduction paths.
Clamping is optimized for transient suppression: signal-path VC = 15 V at IPP = 3 A (IEC 61000-4-5), VBUS-path VC = 20 V at IPP = 10 A, and ESD clamping remains stable across ±8 kV contact discharge pulses with sub-10 ns response. Line symmetry (dCD ≤ 0.05 pF) ensures matched impedance for differential USB pairs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2EUSB30DRBR | 0.7 pF typ. capacitance; supports USB 3.0 (5 Gbps); 3.6 V VRWM; no integrated VBUS protection | Requires separate TVS for 5 V rail; optimized for SuperSpeed differential pairs, not USB 2.0 only | Select when upgrading to USB 3.0 or when lower capacitance is critical; avoid if VBUS protection integration is required |
| ESD5451N-2/TR | 0.5 pF typ. capacitance; 5.5 V VRWM; 12 kV ESD rating; SOT-563 package (larger footprint) | Lacks dedicated VBUS path; rated for lower ESD energy; requires two devices for full 4-line + VBUS coverage | Choose for cost-sensitive USB 2.0 designs where board space permits discrete placement and ESD margin ≥12 kV suffices |
Compared with TPD2EUSB30DRBR and ESD5451N-2/TR, the VBUS054B-HS3-GS08 uniquely integrates VBUS and four signal-line protection in one MSL Level 1 LLP75-6A package with certified ±15 kV immunity - reducing BOM count and layout complexity for USB 2.0 host/device ports without sacrificing signal integrity.

FAQ
What is the primary function of the VBUS054B-HS3-GS08 in a USB 2.0 design?
The VBUS054B-HS3-GS08 provides integrated ESD protection for all four USB 2.0 signal lines (D1+, D1−, D2+, D2−) and the VBUS 5 V supply line in a single LLP75-6A package. It clamps transients to safe levels using a BiAs architecture - with 7.9 V typ. breakdown on data lines and 7.1 V typ. on VBUS - while maintaining 0.8 pF signal-line capacitance to preserve 480 Mbps data integrity. The VBUS054B-HS3-GS08 is placed directly at the USB connector to intercept ESD before it reaches the USB transceiver IC.
Does the VBUS054B-HS3-GS08 support both contact and air discharge ESD testing per IEC 61000-4-2?
Yes, the VBUS054B-HS3-GS08 is rated for ±15 kV contact discharge and ±15 kV air discharge per IEC 61000-4-2, verified across 10 pulses per polarity. Its BiAs structure ensures consistent clamping performance under both discharge modes, with measured peak clamping voltages remaining ≤15 V on signal paths and ≤20 V on the VBUS path during 8/20 µs surge events. This certification makes the VBUS054B-HS3-GS08 suitable for end-equipment compliance testing without additional protection components.
How does the VBUS054B-HS3-GS08 achieve low capacitance while maintaining high ESD immunity?
The VBUS054B-HS3-GS08 uses a series-connected architecture: low-capacitance PN diodes handle signal-line protection (0.8 pF typ.), while a separate avalanche diode protects the VBUS line (110 pF). During normal operation, only the small PN-diode capacitance appears across data lines; the larger Zener capacitance remains effectively invisible due to DC biasing. This design achieves <1 pF signal loading while sustaining ±15 kV ESD immunity - a balance confirmed in Figures 3 and 9 of the VBUS054B-HS3-GS08 datasheet.
What is the significance of the "BiAs" (Bidirectional Asymmetrical) clamping behavior in the VBUS054B-HS3-GS08?
BiAs behavior means the VBUS054B-HS3-GS08 exhibits different forward and reverse clamping thresholds: signal lines clamp at ~0.7 V forward and ~7.9 V reverse, while VBUS clamps at ~7.1 V reverse. This asymmetry prevents false triggering during normal USB signaling (which swings between 0 V and 3.3 V), yet ensures rapid conduction during positive or negative transients. The VBUS054B-HS3-GS08 leverages this to protect both data and power rails without interfering with protocol handshaking or enumeration sequences.
Is the VBUS054B-HS3-GS08 compatible with lead-free reflow processes?
Yes, the VBUS054B-HS3-GS08 is qualified for lead-free reflow per J-STD-020: its LLP75-6A package supports peak temperatures up to 260 °C for 10 seconds at terminals, and it carries MSL Level 1 rating - meaning unlimited floor life and no baking requirement prior to assembly. The device is RoHS-compliant (2011/65/EU) and halogen-free, with lead-free terminations and UL 94 V-0 molding compound, making it fully compatible with standard Pb-free manufacturing flows.
