VBUS054DD-HF4 - 4-Line USB ESD Protection TVS Array | Vishay
MPN: VBUS054DD-HF4 ✓ نشطVBUS054DD-HF4 نظرة عامة
A TVS (Transient Voltage Suppressor) diode array is a discrete semiconductor protection device that clamps fast transient overvoltages to safe levels, protecting downstream ICs from ESD, cable discharge, and surge events. TVS arrays belong to the broader protection-device hierarchy of diodes -> discrete semiconductors, and are commonly co-packaged as multi-channel arrays for high-speed serial interfaces where low capacitance is critical to avoid degrading signal integrity.
Key features include a working range of 5 V, snap-back clamping behavior, an operating temperature range of -40 °C to +125 °C, and a maximum peak pulse power dissipation tailored for USB 2.0 hot-plug and VBUS short-to-battery events. The LLP1010-5L package (1.0 mm × 1.0 mm) is roughly one-fourth the footprint of an SOT-23, enabling ultra-compact designs in mobile phones, wearables, and HDMI/USB-C accessories where board real estate is at a premium.
Architecturally, the VBUS054DD-HF4 integrates zener-based steering diodes that divert transient current away from protected data lines into the ground rail. The flow-through pinout routes D+/D- straight through the package while pin 5 serves as the common ground return, minimizing parasitic inductance and stub effects that would otherwise degrade USB 2.0 high-speed eye diagrams.
Typical applications include USB 2.0 / OTG port protection on smartphones and tablets, HDMI / DisplayPort interface ESD clamps, and 5 V VBUS rail transient protection on docking stations. The 0.8 pF typical capacitance makes it compatible with both USB 2.0 (480 Mbps) and low-speed USB 1.1 signaling.
When designing with this device, place it as close as possible to the external connector and ensure a low-impedance ground connection to pin 5. For USB 2.0 high-speed links, maintain 90 Ω differential impedance through the array and avoid routing high-current transient return paths underneath signal traces.

VBUS054DD-HF4 مناسب لـ 6 التطبيقs: USB 2.0 Type-A Port ESD Protection, Smartphone / Mobile Device Charging Port, HDMI / DisplayPort Interface ESD Clamp, Docking Station / Hub Downstream Port, Automotive Infotainment USB Port, Wearable / Fitness Tracker Side Port.
USB 2.0 Type-A Port ESD Protection
The VBUS054DD-HF4 protects two USB 2.0 high-speed data lines (D+/D-) and the 5 V VBUS rail on a type-A connector. With 0.8 pF typical line capacitance the array adds <1 dB insertion loss at 240 MHz, preserving the USB 2.0 high-speed eye mask. The 19 V clamp voltage and ±15 kV air-discharge rating handle cable-discharge events that occur when a charged cable is plugged into an unpowered host. Place the array within 3 mm of the connector body and tie pin 5 (GND) to the chassis ground plane through 4 vias to maximize transient energy dissipation.

Smartphone / Mobile Device Charging Port
Smartphone micro-USB / USB-C connectors experience daily mechanical wear and ESD events from human contact. The VBUS054DD-HF4's ultra-compact 1.0 mm × 1.0 mm LLP1010-5L footprint saves ~70% board area versus SOT-23 alternatives, a critical advantage in compact phones. The -HF4 halogen-free, RoHS-compliant finish meets Apple and Samsung green-material requirements. Its 19 V clamp tolerates VBUS inductive kickback from in-rush currents during hot-plug charging events, preventing downstream USB controller damage.

HDMI / DisplayPort Interface ESD Clamp
HDMI and DisplayPort TMDS pairs (4 high-speed differential lines per connector) require sub-1 pF capacitance to maintain the 3.4 Gbps / 5.4 Gbps link signal integrity. The VBUS054DD-HF4's 4-line array protects exactly one TMDS pair plus the +5 V supply and hot-plug-detect pin. Its 0.8 pF typical capacitance introduces minimal jitter, while ±15 kV air-discharge rating complies with HDMI 1.4 ESD stress tests. Place the array immediately adjacent to the HDMI connector body to minimize loop area on the discharge path.

Docking Station / Hub Downstream Port
Docking stations typically expose 4-8 downstream USB ports that each need independent ESD protection. The VBUS054DD-HF4's small footprint allows one TVS array per port without crowding the PCB. Its 19 V clamp and 3 A peak pulse current handle the energy from a VBUS short-to-battery fault on an attached device, protecting the upstream hub controller (such as USB2513B-AEZC). Tie pin 5 to the chassis ground plane to bleed chassis-coupled transients.

Automotive Infotainment USB Port
In-vehicle USB ports experience harsher ESD events from occupant contact plus ISO 7637-2 transient disturbances on the 12 V supply rail. The VBUS054DD-HF4's -40 °C to +125 °C operating range covers the AEC-Q100 automotive temperature window, and its 19 V clamp tolerates the load-dump transients typical of automotive power nets. Pair the array with a bulk TVS such as the SMBJ24A on the VBUS rail for two-stage protection.

Wearable / Fitness Tracker Side Port
Fitness bands and smartwatches expose charging pins that, while not true USB, mimic the D+/D-/VBUS topology and require the same ±15 kV ESD robustness. The VBUS054DD-HF4's 1 mm × 1 mm footprint fits within a 6 mm × 6 mm PCB corner near the pogo-pin landing pad. Its 19 V clamp tolerates the inductive kick from the magnetic charging-cable disconnect event, protecting the battery-management IC. Choose the -HF4 halogen-free finish to comply with medical-adjacent wearable material standards.

ملاحظات التصميم
Place the VBUS054DD-HF4 within 3 mm of the USB or HDMI connector body to minimize the transient discharge loop. The flow-through pinout (pins 1-4 carry D+/D-/VBUS signals; pin 5 is GND) requires that pin 5 be tied to the chassis ground plane through a minimum of 4 vias to provide a low-impedance return path for ESD current. Avoid routing high-current transient return paths underneath the protected signal traces to prevent coupling.
For USB 2.0 high-speed (480 Mbps) operation, maintain 90 Ω differential impedance through the VBUS054DD-HF4 footprint. The 0.8 pF typical capacitance introduces <1 dB insertion loss at 240 MHz, but PCB stub effects from improper pin 1/2/3/4 fanout can dominate signal degradation. Use a symmetrical pinout with matched trace lengths on D+ and D- and avoid via transitions within 5 mm of the array.
Estimated: under an 8/20 µs 3 A peak pulse, instantaneous power dissipation reaches 57 W in the VBUS054DD-HF4. While the pulse duration is short, repeated stress events (e.g., a hot-plug arc every few minutes in a test environment) can raise junction temperature. Ensure at least 10 mm² of 1 oz copper under the LLP1010-5L thermal pad for heat spreading, and consider the SMBJ24A on the VBUS rail as a coarser first-stage clamp to reduce stress on this part.
Do not use the VBUS054DD-HF4 to protect CC/SBU lines on USB Type-C ports without verifying that the 19 V clamp voltage is within the CC pin's 5 V tolerant specification - the 19 V clamp may damage the CC logic. For USB Type-C, use a dedicated CC protection part such as the TPD4E05U06 or ESD8004 instead. Also note that the -HF4 suffix indicates halogen-free finish; if a non-halogen-free version is required, the bare VBUS054DD-HF4 (without -HF4) is no longer widely stocked.
