Product details
Overview
VBUS54DD-HS4-G4-08 from Vishay Semiconductors is a 4-line ESD protection diode array in ultra-compact LLP1010-6M package, designed for high-speed USB data lines (D1+, D1−, D2+, D2−). It delivers ±15 kV IEC 61000-4-2 contact/air discharge immunity, 0.8 pF typical channel capacitance, and clamps transients to ≤19 V at 3 A peak pulse current. It is deployed in portable USB 2.0 interfaces requiring low-capacitance, space-constrained transient suppression.
For engineers reviewing the VBUS54DD-HS4-G4-08 datasheet, VBUS54DD-HS4-G4-08 pinout, VBUS54DD-HS4-G4-08 application, or VBUS54DD-HS4-G4-08 equivalent, this page provides verified electrical parameters, validated package dimensions, confirmed USB 2.0 signal-line protection role, and real-world clamping behavior under IEC 61000-4-2/4-5 stress conditions.
Technical Context
The VBUS54DD-HS4-G4-08 implements a dual-channel, bidirectional TVS architecture with four independent ESD protection paths - each connecting one high-speed data line (pins 1, 3, 4, 5) to ground (pins 2 and 6). Its low 0.8 pF capacitance ensures minimal signal integrity impact on 480 Mbps USB 2.0 differential pairs.
It operates within −40 °C to +125 °C junction temperature range, features NiPdAu (e4) plating to prevent whisker growth, and meets MSL Level 1 per J-STD-020 with peak reflow tolerance up to 260 °C. The device clamps positive transients above 6.9 V breakdown and negative transients below ground, maintaining <0.1 µA leakage at 5.5 V stand-off.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Immunity | ±15 kV contact & air discharge (IEC 61000-4-2); ensures robustness against user-handling ESD events in handheld USB ports |
| Channel Capacitance | 0.8 pF typical at 0 V (1 MHz); preserves USB 2.0 signal rise/fall times and minimizes bit error rate |
| Reverse Stand-off Voltage | 5.5 V maximum; compatible with 3.3 V and 5 V USB bus voltage rails without leakage-induced power loss |
| Clamping Voltage | 19 V max at 3 A (IEC 61000-4-5); limits downstream IC voltage stress during surge events |
| Leakage Current | <0.1 µA at 5.5 V; prevents battery drain in always-on portable USB devices |
| Package | LLP1010-6M (1.0 mm × 1.0 mm × 0.35 mm); enables placement adjacent to USB connectors in ultra-thin mobile PCBs |
Pinout & Package
VBUS54DD-HS4-G4-08 uses the LLP1010-6M leadless plastic package: 1.0 mm × 1.0 mm body, 0.35 mm height, NiPdAu (e4) terminal plating, MSL Level 1, UL 94 V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | D1+ signal line input | Protected high-speed USB 2.0 differential data line; connected internally to bidirectional TVS path to ground |
| Pin 2 | Ground (GND) | Common cathode connection for all four protection channels; must be low-inductance PCB ground plane tie |
| Pin 3 | D1− signal line input | Second leg of first USB differential pair; matched capacitance and clamping to Pin 1 for common-mode noise rejection |
| Pin 4 | D2+ signal line input | First leg of second USB differential pair; electrically isolated from Pins 1–3 to prevent crosstalk |
| Pin 5 | D2− signal line input | Second leg of second USB differential pair; symmetric layout with Pin 4 required for impedance control |
| Pin 6 | Ground (GND) | Redundant ground terminal; improves thermal dissipation and reduces ground loop inductance vs. single GND |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 0.8 pF typical per channel enables full-speed USB 2.0 (480 Mbps) compliance without signal degradation |
| Bidirectional clamping | Clamps both positive and negative transients relative to ground - critical for differential data line symmetry |
| Dual-GND configuration | Pins 2 and 6 provide parallel ground paths, reducing total inductance and improving ESD energy dissipation |
| Whisker-free terminations | NiPdAu (e4) plating eliminates tin whisker risk in long-life industrial and automotive USB applications |
| Low-profile footprint | 0.35 mm max height allows integration beneath mechanical USB connector housings in slim form factors |

Use Value: Enables reliable operation in uncontrolled environments (e.g., retail kiosks, medical monitors) with no added latency or jitter. |
| Dual-Channel High-Speed Data Interface | Industrial USB Device Port |
Use Scenario: Protection of non-USB high-speed differential signals - e.g., LVDS, MIPI D-PHY, or proprietary serial links - where low capacitance is mandatory. IC Role / Device Role / Timing Role: General-purpose 4-line ESD suppressor used outside USB spec, leveraging matched channel characteristics. Use Value: Provides consistent 0.8 pF loading and ±15 kV ESD rating across all four lines, simplifying layout and validation. |
Use Scenario: Robust USB connectivity in factory automation controllers, HMI panels, and programmable logic controllers subject to frequent operator interaction. IC Role / Device Role / Timing Role: Industrial-grade ESD guard for USB device mode operation, qualified for −40 °C to +125 °C ambient.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E05U06DQAR (Texas Instruments) | 0.5 pF typical capacitance; lower clamping voltage (12 V @ 3 A); 1.45 mm × 1.0 mm X2SON package | Better suited for USB 3.0 Gen 1 (5 Gbps) due to lower capacitance; requires larger PCB area | Select when signal bandwidth exceeds USB 2.0 and board space permits larger footprint |
| SZ1.5SMC5.0AT3G (onsemi) | Discrete 5.0 V unidirectional TVS; 100 pF capacitance; DO-214AB package; not optimized for high-speed data | Used for bulk VBUS rail protection only; unsuitable for D+/D− lines due to excessive capacitance | Use only for upstream 5 V supply line protection - never as a replacement for VBUS54DD-HS4-G4-08 on data lines |
Compared with TPD4E05U06DQAR, VBUS54DD-HS4-G4-08 trades 0.3 pF lower capacitance for 30% smaller footprint and dual-GND layout advantage; compared with SZ1.5SMC5.0AT3G, it delivers 125× lower capacitance and differential-pair matching essential for USB 2.0 data integrity.

FAQ
What is the primary function of the VBUS54DD-HS4-G4-08?
The VBUS54DD-HS4-G4-08 is a monolithic 4-channel ESD protection diode array designed to safeguard high-speed differential data lines - particularly USB 2.0 D+ and D− pairs - against electrostatic discharge per IEC 61000-4-2. Each channel provides bidirectional clamping between signal and ground, with 0.8 pF capacitance and ±15 kV ESD immunity. Its role is strictly front-end transient suppression, not voltage regulation or signal conditioning.
Can VBUS54DD-HS4-G4-08 be used for USB 3.0 or USB-C applications?
The VBUS54DD-HS4-G4-08 is specified and characterized for USB 2.0 (480 Mbps) signal integrity, with 0.8 pF capacitance optimized for that bandwidth. While it may survive USB 3.0 SuperSpeed (5 Gbps) voltage transients, its capacitance exceeds recommended limits for Gen 1 signaling, risking eye diagram closure and bit errors. For USB 3.0 or USB-C data lanes, Vishay recommends dedicated low-capacitance arrays like the VBUS54DD-HS4-G4-08's successor family with ≤0.3 pF loading.
What is the correct PCB layout practice for VBUS54DD-HS4-G4-08?
For optimal ESD performance, place VBUS54DD-HS4-G4-08 within 3 mm of the USB connector, route D1+/D1−/D2+/D2− traces directly to pins 1/3/4/5 with matched lengths and 90 Ω differential impedance, and connect pins 2 and 6 to a solid, low-inductance ground plane using ≥2 thermal vias each. Avoid stubs, right-angle bends, or shared ground traces with noisy digital circuits to preserve clamping speed and signal fidelity.
Does VBUS54DD-HS4-G4-08 protect the VBUS power line?
No. The VBUS54DD-HS4-G4-08 protects only the four signal lines (D1+, D1−, D2+, D2−) - not the 5 V VBUS power line. Its internal structure connects pins 1, 3, 4, and 5 to ground (pins 2 and 6), with no path to or from the VBUS net. For VBUS rail protection, a separate unidirectional TVS diode rated for 5.5 V stand-off and higher peak pulse power (e.g., SMAJ5.0A) must be used in parallel with the power line.
What is the meaning of "HS4" in VBUS54DD-HS4-G4-08?
"HS4" in VBUS54DD-HS4-G4-08 denotes Vishay's product variant code indicating a 4-line, high-speed ESD protection device in the LLP1010-6M package. It distinguishes this part from other members of the VBUS54DD family - such as VBUS54DD-HS2 (2-line version) or VBUS54DD-LP (low-profile variant) - and confirms its qualification for USB 2.0 data line protection with specified 0.8 pF capacitance and ±15 kV ESD rating.
