Product details
Overview
VBUS051CD-HD1-G-08 from Vishay Semiconductors is a single-line, low-capacitance ESD protection diode in the LLP1006-2L package, rated for 5.5 V reverse stand-off voltage, 0.6 pF typical capacitance, and ±15 kV IEC 61000-4-2 contact/air discharge immunity - designed for high-speed USB 2.0 data line protection.
For engineers reviewing the VBUS051CD-HD1-G-08 datasheet, VBUS051CD-HD1-G-08 pinout, VBUS051CD-HD1-G-08 application, or VBUS051CD-HD1-G-08 equivalent, key selection criteria include clamping voltage (≤14 V at 2 A), ultra-low leakage (<0.1 μA), bidirectional asymmetrical (BiAs) Zener-like behavior, and MSL Level 1 solderability with peak temperature up to 260 °C.
Technical Context
The VBUS051CD-HD1-G-08 implements a bidirectional asymmetrical (BiAs) Zener-based clamping structure: it clamps positive transients above ~5.5 V and negative transients below ground, enabling optimal protection for 5 V nominal systems. Its 0.6 pF capacitance minimizes signal distortion on high-frequency lines.
It operates across –40 °C to +125 °C junction temperature, supports 2 A peak pulse current per IEC 61000-4-5 (8/20 μs), and features NiPdAu (e4) plating to prevent whisker growth - critical for compact, reliability-sensitive portable electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 5.5 V - maximum continuous working voltage before conduction begins; ensures no interference with 5 V logic/data signals. |
| Capacitance (CD) | 0.6 pF typ. at 0 V, 1 MHz - preserves signal integrity on USB 2.0 (480 Mbps) and HDMI DDC lines. |
| ESD Immunity | ±15 kV contact & air discharge per IEC 61000-4-2 - meets industrial and consumer ESD robustness requirements. |
| Clamping Voltage (VC) | ≤14 V at IPP = 2 A (IEC 61000-4-5) - limits transient overvoltage seen by downstream ICs. |
| Leakage Current (IR) | <0.1 μA at VRWM = 5.5 V - avoids loading of high-impedance data lines or battery-powered circuits. |
| Package | LLP1006-2L - 1.05 × 0.65 mm footprint, <0.4 mm height, MSL Level 1 - enables ultra-thin mobile PCB designs. |
Pinout & Package
LLP1006-2L is a 2-terminal surface-mount package with cathode marking (bar) on Pin 1. Total weight: 0.72 mg. Mold compound: UL 94 V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode / Ground connection | Connected to system ground; serves as reference for bidirectional clamping and surge return path. |
| Pin 2 | Anode / Data line connection | Connected directly to protected high-speed line (e.g., USB D+); conducts during positive transients and blocks during normal operation. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Asymmetrical (BiAs) Clamping | Clamps positive surges above 5.5 V and negative surges below ground - optimized for 5 V bus protection without forward-biasing during normal operation. |
| Ultra-Low Capacitance | 0.6 pF typical - eliminates signal rise-time degradation and bit-error-rate impact on 480 Mbps USB 2.0 links. |
| High Surge Robustness | 2 A peak pulse current (IEC 61000-4-5, 8/20 μs) - withstands multiple high-energy transients without parametric shift or failure. |
| Whisker-Free Termination | NiPdAu (e4) plating - eliminates tin whisker risk in long-life, high-reliability applications such as automotive infotainment and medical wearables. |
Applications
| USB 2.0 Data Line Protection | HDMI DDC Channel Protection |
|---|---|
Use Scenario: Protecting D+ and D− lines in smartphone, tablet, or peripheral USB ports against ESD events during cable insertion/removal. IC Role / Device Role / Timing Role: Standalone ESD suppressor placed in series with each data line, grounded to chassis or digital ground. Use Value: Prevents latch-up or damage to USB transceivers while maintaining eye diagram compliance due to 0.6 pF capacitance. | Use Scenario: Safeguarding the HDMI Display Data Channel (DDC) I²C bus (SCL/SDA) from ESD during hot-plug detection and EDID communication. IC Role / Device Role / Timing Role: Low-capacitance shunt protector on each DDC line, referenced to system ground. Use Value: Ensures uninterrupted EDID handshake and display enumeration by limiting transient-induced glitches below I²C timing thresholds. |
| Industrial Sensor Interface Protection | Portable Audio DAC/ADC Line Protection |
Use Scenario: Shielding RS-485 or CAN FD physical layer receivers in factory automation gateways exposed to field ESD. IC Role / Device Role / Timing Role: Point-of-entry ESD clamp on differential signal pairs, leveraging BiAs behavior to avoid DC bias disruption. Use Value: Maintains common-mode range integrity and prevents false triggering of fault detection circuitry during ±15 kV discharges. | Use Scenario: Protecting analog audio paths (e.g., I²S clock/data lines) in Bluetooth headphones or smart speakers from user-hand ESD. IC Role / Device Role / Timing Role: Shunt-type transient suppressor on high-speed digital audio buses adjacent to sensitive analog sections. Use Value: Eliminates audible pop/click artifacts caused by ESD-induced coupling, verified via 0.6 pF load and sub-μA leakage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VBUS05N1-HD1 | Same LLP1006-2L package; identical 5.5 V VRWM and 0.6 pF CD; ±15 kV ESD rating; but specified for new designs (VBUS051CD-HD1 is Not for New Designs). | Drop-in replacement with updated qualification and extended lifecycle support; no layout or schematic change required. | Select VBUS05N1-HD1 for new designs requiring long-term supply assurance and latest Vishay process revision. |
| SMA6J5.0A | DO-214AC package; higher capacitance (≈100 pF); 5.0 V VRWM; unidirectional; larger footprint (4.3 × 2.6 mm vs. 1.05 × 0.65 mm). | Suitable only for lower-speed, space-tolerant applications (e.g., power rail or UART lines); not viable for USB/HDMI. | Choose SMA6J5.0A only when board area and signal speed constraints permit higher capacitance and larger size. |
Compared with VBUS051CD-HD1-G-08, VBUS05N1-HD1 offers identical electrical performance in a qualified-for-new-designs variant, while SMA6J5.0A trades miniaturization and bandwidth for ruggedness and cost in non-high-speed roles - making VBUS05N1-HD1 the preferred upgrade path for next-gen USB 2.0 implementations.

FAQ
Is VBUS051CD-HD1-G-08 suitable for USB 2.0 high-speed (480 Mbps) data lines?
Yes, VBUS051CD-HD1-G-08 is explicitly validated for USB 2.0 applications. Its 0.6 pF typical capacitance ensures minimal signal integrity impact, and its bidirectional asymmetrical clamping maintains DC bias while suppressing ±15 kV ESD transients - meeting USB-IF compliance requirements for host and peripheral port protection.
What is the meaning of "Not for New Designs" for VBUS051CD-HD1-G-08?
"Not for New Designs" indicates Vishay has superseded VBUS051CD-HD1-G-08 with VBUS05N1-HD1 for future projects. VBUS051CD-HD1-G-08 remains fully functional and supported for existing production, but new designs should use VBUS05N1-HD1 to ensure long-term availability and latest process qualifications.
Does VBUS051CD-HD1-G-08 require special PCB layout considerations?
Yes - place VBUS051CD-HD1-G-08 as close as possible to the protected connector (ideally ≤5 mm), route the protected line directly to Pin 2, and connect Pin 1 to a low-inductance ground plane. Avoid vias or stubs in the protection path to preserve its 0.6 pF advantage and clamping response time.
Can VBUS051CD-HD1-G-08 protect both positive and negative ESD transients?
Yes, VBUS051CD-HD1-G-08 provides bidirectional asymmetrical (BiAs) clamping: it clamps positive transients above ~5.5 V and negative transients below ground level. This dual-polarity response is confirmed in its IEC 61000-4-2 ±15 kV rating and clamping curves (Figs. 7–8 in the datasheet).
What is the maximum operating temperature range for VBUS051CD-HD1-G-08?
VBUS051CD-HD1-G-08 is rated for junction temperatures from –40 °C to +125 °C. This range supports deployment in automotive cabin modules, industrial edge controllers, and consumer devices operating under thermal stress - verified per JEDEC JESD22-A108 thermal cycling and JESD22-A103 HTOL testing.
