Product details
Overview
VBUS054B-HSF-GS08 from Vishay Semiconductors is a 4-line bidirectional ESD protection diode array designed for high-speed USB 2.0 data lines (D1+, D1−, D2+, D2−) and VBUS supply line protection. It features 0.8 pF typical line-to-ground capacitance, ±15 kV IEC 61000-4-2 contact/air discharge immunity, and a compact LLP75-6L package with <0.6 mm height - ideal for space-constrained mobile and portable USB interfaces.
For engineers reviewing the VBUS054B-HSF-GS08 datasheet, VBUS054B-HSF-GS08 pinout, VBUS054B-HSF-GS08 application, or VBUS054B-HSF-GS08 equivalent, key selection criteria include low-capacitance signal integrity preservation, asymmetric clamping behavior for data/supply lines, MSL Level 1 soldering compatibility, and verified 4-line USB port protection architecture.
Technical Context
The VBUS054B-HSF-GS08 integrates six discrete protection elements in one LLP75-6L package: four low-capacitance PN diodes (pins 1/3/4/6 to pin 2) for data-line ESD clamping, and one high-power avalanche diode (pin 5 to pin 2) for VBUS line protection. Its BiAs (Bidirectional Asymmetrical) clamping architecture delivers distinct forward/reverse clamping voltages per path - 15 V reverse clamping at 3 A for data lines, and 200 W peak pulse power handling on the VBUS path.
It operates across −40 °C to +125 °C junction temperature, supports 5 V nominal working voltage on data lines (VRWM = 5 V), and maintains <0.1 μA leakage at stand-off. The device uses e4 precious-metal termination (NiPdAu) and UL 94 V-0 molding compound, meeting IPC/JEDEC J-STD-020 MSL Level 1 reflow requirements up to 260 °C peak.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E004DRYR | 4-channel, 0.75 pF typical capacitance, ±12 kV IEC 61000-4-2, SOT-563 package (1.6 × 1.6 mm) | Lower ESD rating and larger footprint; lacks dedicated high-power VBUS path | Preferred when board space allows larger package and VBUS surge immunity is secondary to ultra-low capacitance |
| ESD5451N-2/TR | 4-line, 0.5 pF typical capacitance, ±15 kV ESD, X1-DFN1006-3 package (1.0 × 0.6 mm), no integrated VBUS clamp | Smaller size but requires external VBUS TVS; optimized for minimal trace capacitance only | Chosen when VBUS protection is handled separately and PCB real estate is extremely limited |
Compared with TPD4E004DRYR and ESD5451N-2/TR, VBUS054B-HSF-GS08 uniquely integrates a dedicated 200 W VBUS clamping path alongside 4×0.8 pF data-line protection - eliminating external components and simplifying layout for full-port USB 2.0 protection in single-package form.

FAQ
What is the primary function of the VBUS054B-HSF-GS08 in a USB 2.0 interface?
The VBUS054B-HSF-GS08 serves as a monolithic 4-line ESD protection device for USB 2.0 data pairs (D1+/D1−/D2+/D2−) and the VBUS supply line. It uses low-capacitance PN diodes for signal-line clamping and a high-power avalanche diode for VBUS rail protection - all in a single LLP75-6L package. This architecture ensures ±15 kV IEC 61000-4-2 immunity without compromising 480 Mbps signal integrity, making VBUS054B-HSF-GS08 essential for robust, miniaturized USB port designs.
Does the VBUS054B-HSF-GS08 support USB 3.0 or higher data rates?
No, the VBUS054B-HSF-GS08 is specified and characterized for USB 2.0 (480 Mbps) applications only. Its 0.8 pF typical capacitance is optimized for that speed class; USB 3.0 SuperSpeed (5 Gbps) and beyond require sub-0.3 pF capacitance and different clamping topologies. For USB 3.x, Vishay offers dedicated solutions such as the USB3XXX series - VBUS054B-HSF-GS08 must not be substituted in those designs without full signal-integrity validation.
How does the BiAs (Bidirectional Asymmetrical) clamping architecture benefit USB system design?
The BiAs architecture in VBUS054B-HSF-GS08 enables independent optimization: data lines (pins 1/3/4/6) clamp at 15 V reverse and 5 V forward, while the VBUS line (pin 5) clamps at 7.1 V breakdown with 200 W surge capability. This eliminates trade-offs between low-capacitance signal fidelity and high-energy supply-rail protection - allowing designers to meet both USB-IF electrical specs and IEC 61000-4-5 surge requirements using a single VBUS054B-HSF-GS08 device instead of multiple discrete protectors.
What is the maximum operating temperature range for the VBUS054B-HSF-GS08?
The VBUS054B-HSF-GS08 has a specified junction temperature range of −40 °C to +125 °C, with storage temperature from −55 °C to +150 °C. This extended range supports deployment in harsh environments including automotive under-hood modules, industrial HMIs, and outdoor portable electronics. Derating curves in the official Vishay datasheet (Doc. #81624, Rev. 1.9) confirm stable clamping performance across this full range without parameter shift or reliability degradation.
Can the VBUS054B-HSF-GS08 be used in place of discrete 0402 ESD diodes for each USB line?
Yes - VBUS054B-HSF-GS08 replaces up to five discrete 0402 ESD diodes (four for D+/D− lines plus one for VBUS) while improving layout density, reducing assembly cost, and ensuring matched capacitance and timing across all protected lines. Its LLP75-6L package occupies less than half the PCB area of five 0402s and guarantees symmetrical clamping response critical for differential USB signaling - a key advantage over discrete implementations where component tolerances can skew eye diagrams.
