Product details
Overview
VBUS54ED-FBL-G4-08 from Vishay Semiconductors is a 4-line bidirectional asymmetrical (BiAs) ESD protection diode array in LLP2510-10L package, rated for ±15 kV IEC 61000-4-2 contact/air discharge, 5.5 V reverse stand-off voltage, 0.3 pF inter-line capacitance, and 2 A peak pulse current - deployed on HDMI, USB 3.0, and Thunderbolt data lanes.
For engineers reviewing the VBUS54ED-FBL-G4-08 datasheet, VBUS54ED-FBL-G4-08 pinout, VBUS54ED-FBL-G4-08 application, or VBUS54ED-FBL-G4-08 equivalent, this device is selected for high-speed differential signal protection where sub-1 pF line-to-ground capacitance, flow-through PCB layout compatibility, and clamping below ground/near 5.5 V are critical design requirements.
Technical Context
The VBUS54ED-FBL-G4-08 implements a Zener-based BiAs clamping architecture with separate forward and reverse conduction paths per channel: negative transients clamp to ~–0.7 V (relative to GND), positive transients clamp to ≤12.5 V at 2 A, enabling robust protection without disrupting 5.5 V logic-level signaling. Its matched-pair D1+/D1− and D2+/D2− channels maintain <0.4 pF inter-line capacitance to preserve signal integrity up to 1.65 Gbit/s.
Designed for flow-through routing, the LLP2510-10L package places pins 1–2 and 4–5 linearly aligned across the body, eliminating vias or stubs in high-speed trace paths. Pins 3 and 8 are internally shorted GND terminals; pins 6, 7, 9, 10 are NC - ensuring minimal impedance discontinuity on USB/HDMI differential pairs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±15 kV contact & air discharge (IEC 61000-4-2): ensures immunity to human-body-model ESD events in handheld and docking interfaces. |
| Reverse Stand-off Voltage | 5.5 V: maximum continuous working voltage before leakage exceeds 0.1 μA - matches USB 3.0 and HDMI TMDS common-mode range. |
| Inter-line Capacitance | 0.3 pF (typ. @ 3.3 V): minimizes crosstalk and insertion loss on differential pairs like HDMI D0+/D0− or USB SS RX+/RX−. |
| Clamping Voltage | 10.3 V (max @ 2 A IPPM): limits transient overvoltage to safe levels for 5 V-tolerant PHY receivers without latch-up risk. |
| Leakage Current | 0.02 μA (typ. @ 5.5 V VRWM): prevents DC loading of high-impedance data lines, preserving signal swing and timing margins. |
| Package | LLP2510-10L (2.5 × 1.0 × 0.55 mm): ultra-low profile flow-through design enables direct in-line placement on 50 Ω controlled-impedance traces. |
Pinout & Package
LLP2510-10L is a 10-pin leadless plastic package with 0.5 mm pitch, 2.5 mm × 1.0 mm footprint, and max height of 0.6 mm. Pin 1 marked by dot; pins 3 and 8 internally shorted to GND; pins 6, 7, 9, 10 unconnected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | D1+ / D1− input | Differential pair for first high-speed interface (e.g., USB 3.0 SSTX+/SSTX− or HDMI TMDS Clock+/−). |
| 4, 5 | D2+ / D2− input | Differential pair for second high-speed interface (e.g., USB 3.0 SSRX+/SSRX− or HDMI TMDS D0+/D0−). |
| 3, 8 | GND | Internally shorted ground terminals - must be connected to system ground plane with low-inductance path for effective clamping. |
| 6, 7, 9, 10 | No Connect | Not bonded; no internal connection - may be left floating or tied to GND for mechanical stability (no electrical effect). |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Asymmetrical Clamping | Clamps negative transients to ~–0.7 V and positive transients to ≤12.5 V - protects both sides of 5.5 V-referenced differential signals without biasing disruption. |
| Flow-Through Layout Compatibility | Linear pin arrangement (1–2–3–4–5 across top row; 10–9–8–7–6 across bottom) allows uninterrupted 50 Ω trace routing - eliminates stubs, vias, and impedance mismatch. |
| Ultra-Low Inter-Line Capacitance | 0.3 pF between D1+/D1− and D2+/D2− - preserves eye diagram integrity and jitter margin in 1.65 Gbit/s HDMI and 5 Gbit/s USB 3.0 links. |
| e4 Finish (NiPdAu) | Precious-metal termination ensures reliable solder wetting and long-term intermetallic stability under thermal cycling - critical for automotive and industrial connector interfaces. |
Applications
| HDMI Interface Protection | USB 3.0 SuperSpeed Lane Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VBUS052CD-FAH | 2-line variant, same LLP2510-10L package, 0.3 pF CDD, but only two protected channels. | Suitable for single differential pair (e.g., USB 2.0 D+/D− or HDMI Clock only), not full 4-lane protection. | Select when protecting only two high-speed lines - reduces BOM count and PCB area vs. using two VBUS54ED-FBL-G4-08 units. |
| TPD4E001DQAR | Texas Instruments 4-channel ESD protector in X2SON-10 package; 0.5 pF CDD, ±12 kV ESD rating, 5.5 V VRWM. | Lower ESD immunity (±12 kV vs. ±15 kV) and higher inter-line capacitance - may require margin validation in harsh ESD environments. | Choose if TI supply chain alignment or alternate qualification requirements drive selection; verify clamping performance at 2 A IPPM. |
Compared with VBUS052CD-FAH and TPD4E001DQAR, the VBUS54ED-FBL-G4-08 delivers superior ESD immunity (±15 kV), lower inter-line capacitance (0.3 pF), and native 4-lane flow-through routing - making it optimal for HDMI 2.0, USB 3.0, and Thunderbolt ports requiring simultaneous multi-lane protection without layout compromise.

FAQ
What is the maximum working voltage supported by the VBUS54ED-FBL-G4-08?
The VBUS54ED-FBL-G4-08 has a reverse stand-off voltage (VRWM) of 5.5 V, meaning it can continuously withstand up to 5.5 V DC or peak AC signals without significant leakage. This aligns with the common-mode voltage range of USB 3.0, HDMI TMDS, and DisplayPort main link signals. The VBUS54ED-FBL-G4-08 begins clamping above this threshold during ESD events, maintaining system-level signal integrity.
How does the VBUS54ED-FBL-G4-08 achieve flow-through PCB layout compatibility?
The VBUS54ED-FBL-G4-08 uses a linear pinout in the LLP2510-10L package: pins 1–2–3–4–5 run across the top edge, and pins 10–9–8–7–6 mirror them on the bottom. This allows high-speed differential traces to pass straight through the device without vias, stubs, or bends - preserving 50 Ω impedance and minimizing reflections. The VBUS54ED-FBL-G4-08 achieves this via internal die routing that maps I/O pins directly across the package body.
What is the significance of the BiAs (Bidirectional Asymmetrical) clamping behavior in the VBUS54ED-FBL-G4-08?
BiAs clamping means the VBUS54ED-FBL-G4-08 clamps negative transients to approximately –0.7 V (near diode drop below GND) and positive transients to ≤12.5 V (at 2 A), rather than symmetrically around 0 V. This asymmetry matches the unidirectional voltage swing of 5.5 V-referenced high-speed interfaces, preventing false triggering and ensuring clamping occurs only when needed - a key advantage of the VBUS54ED-FBL-G4-08 over generic symmetrical TVS diodes.
Can the VBUS54ED-FBL-G4-08 be used for USB 2.0 D+/D− protection?
Yes, the VBUS54ED-FBL-G4-08 supports USB 2.0 D+/D− protection: its 0.3 pF inter-line capacitance and 5.5 V VRWM meet USB 2.0 electrical specifications, and its ±15 kV ESD rating exceeds USB-IF requirements. However, since USB 2.0 uses only one differential pair, using the full 4-line VBUS54ED-FBL-G4-08 may be over-spec'd; VBUS052CD-FAH (2-line) is often more cost- and space-efficient for USB 2.0-only designs.
What is the moisture sensitivity level (MSL) and reflow profile for the VBUS54ED-FBL-G4-08?
The VBUS54ED-FBL-G4-08 is rated MSL level 1 per J-STD-020, meaning it is not moisture-sensitive and can be stored indefinitely at ambient conditions without dry-pack requirements. Its recommended soldering condition is 260 °C peak temperature at terminals for 10 seconds - compatible with standard lead-free reflow profiles. This MSL 1 rating simplifies manufacturing logistics and eliminates bake-out steps for the VBUS54ED-FBL-G4-08.
