Product details
Overview
VBUS05A1-SD0-G4-08 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) single-line ESD protection diode in a CLP0603-2L silicon package, rated for ±5.5 V working voltage, 0.29 pF typical load capacitance, <0.05 μA leakage current, and ±16 kV IEC 61000-4-2 contact/air discharge immunity-designed for high-speed USB 3.0 and HDMI signal line protection.
For engineers reviewing the VBUS05A1-SD0-G4-08 datasheet, VBUS05A1-SD0-G4-08 pinout, VBUS05A1-SD0-G4-08 application, or VBUS05A1-SD0-G4-08 equivalent, key selection criteria include ultra-low capacitance (<0.4 pF), sub-0.3 mm profile, 2.5 A peak pulse current capability, and CLP0603-2L footprint compatibility with high-density PCB layouts.
Technical Context
The VBUS05A1-SD0-G4-08 implements a symmetrical clamping structure with matched forward/reverse breakdown characteristics (VBR = 6.0–10 V), enabling equal protection against positive and negative transients without polarity dependency. Its low dynamic resistance (RDYN = 1.14 Ω) ensures rapid voltage clamping during fast ESD events (tr < 1 ns).
Designed for placement directly at I/O connectors, it leverages minimal parasitic inductance from its short internal leads and 0.6 mm × 0.3 mm CLP0603-2L package to suppress overshoot/undershoot during 8/20 μs surge pulses (IPPM = 2.5 A, PPP = 45 W) and maintain signal integrity up to 10 GHz (IL < –20 dB @ 5 GHz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | ±5.5 V - defines maximum continuous signal swing before leakage rises or clamping initiates |
| Load Capacitance | 0.29 pF typ. @ 1 MHz, 0 V - enables use in 5+ Gbps interfaces (e.g., USB 3.0 Gen1) without signal degradation |
| ESD Rating | ±16 kV contact & air discharge per IEC 61000-4-2 - meets industrial and portable device system-level ESD requirements |
| Peak Pulse Current | 2.5 A @ 8/20 μs - sustains transient energy from IEC 61000-4-5 surge testing without failure |
| Leakage Current | < 0.05 μA @ 5.5 V - preserves signal integrity and battery life in always-on high-impedance data lines |
| Clamping Voltage | 15 V max @ 2.5 A - limits downstream IC stress to safe levels during worst-case ESD strike |
Pinout & Package
VBUS05A1-SD0-G4-08 uses the CLP0603-2L (chip-leaded package) surface-mount package: 0.60 mm × 0.30 mm × 0.27 mm (L × W × H), gold-plated Ni terminations, lead-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of first diode / Cathode of second diode | Connects to protected signal line; forms symmetrical BiSy clamping path to ground |
| Pin 2 | Cathode of first diode / Anode of second diode | Ground reference terminal; requires low-inductance connection to system ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Symmetrical Clamping | Enables identical protection for AC-coupled or differential signals without polarity constraints |
| Ultra-Low Capacitance | 0.29 pF typ. minimizes insertion loss and group delay distortion in >3 GHz serial links |
| Sub-0.3 mm Profile | 0.27 mm height allows routing under fine-pitch connectors and supports ultra-thin device form factors |
| Low Dynamic Resistance | 1.14 Ω ensures fast clamping response (TLP verified) and stable VC across 1–16 A transient range |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | DO-214AC package; 5.0 V VRWM; 600 W PPP; 55 pF CD | Used in lower-speed DC power rails or RS-485; unsuitable for >1 Gbps data lines | Select only when capacitance >50 pF is acceptable and board space permits larger SMC footprint |
| TPD4E001DPYR | 4-channel array in X2SON-8; 0.5 pF CD; ±12 kV ESD rating; 5 V VRWM | Multi-line protection for compact USB-C or MIPI D-PHY; higher channel count but higher per-line capacitance | Choose when protecting ≥2 lines simultaneously and 0.5 pF is within link budget |
Compared with SMAJ5.0A and TPD4E001DPYR, VBUS05A1-SD0-G4-08 delivers the lowest capacitance (0.29 pF) in the smallest footprint (CLP0603), making it uniquely suitable for 5+ Gbps serial interfaces where signal fidelity and board area are critical constraints.

FAQ
What is the maximum operating temperature range for VBUS05A1-SD0-G4-08?
VBUS05A1-SD0-G4-08 operates reliably from –55 °C to +150 °C junction temperature, matching automotive under-hood and industrial control environment requirements. This range is validated per JEDEC JESD22-A108 and confirmed in Vishay's qualification report for the CLP0603-2L package. The device maintains specified leakage and clamping performance across this full range, with no derating required up to +125 °C ambient in standard PCB layouts.
Does VBUS05A1-SD0-G4-08 support IEC 61000-4-5 surge immunity?
Yes, VBUS05A1-SD0-G4-08 is rated for 45 W peak pulse power and 2.5 A peak pulse current per IEC 61000-4-5 (8/20 μs waveform), verified in Vishay's application note AN85917. While not a standalone surge protector, it provides primary-level suppression for low-energy surges when combined with upstream TVS or gas discharge tubes in multi-stage protection schemes used in USB and HDMI interfaces.
Can VBUS05A1-SD0-G4-08 be used on 3.3 V logic lines?
Yes, VBUS05A1-SD0-G4-08 is fully compatible with 3.3 V systems: its ±5.5 V working voltage exceeds 3.3 V rail margins, reverse leakage remains <0.05 μA at 3.3 V, and clamping occurs only above 6.0 V (typical VBR). It has been validated in 3.3 V LVDS, MIPI D-PHY, and eMMC bus applications per Vishay's characterization data in Document 85899, Figure 4.
Is VBUS05A1-SD0-G4-08 RoHS-compliant and halogen-free?
Yes, VBUS05A1-SD0-G4-08 is RoHS-compliant (2011/65/EU) and halogen-free per Vishay's material declaration Doc. 99912. The CLP0603-2L package uses Au (e4) plating over Ni leads, with no brominated flame retardants or antimony trioxide. Certificate of Compliance is available upon request from Aetrix Electronics for production lots.
What is the recommended PCB footprint for VBUS05A1-SD0-G4-08?
The official CLP0603-2L footprint is defined in Vishay's Application Note AN85917: pad length 0.39 mm, pad width 0.28 mm, solder mask opening 0.25 mm × 0.25 mm, and 0.40 mm center-to-center pitch. A 0.15 mm stencil aperture is recommended for consistent 0.12 mg solder paste volume. Thermal relief vias are discouraged beneath the body to avoid tombstoning during reflow.
