Product details
Overview
VESD05A8A-HNH-GS08 from Vishay Semiconductors is an 8-line bidirectional asymmetrical ESD protection diode array in LLP1713-9L package, rated for 5 V working voltage (VRWM), 30 pF typical capacitance at 0 V, ±25 kV IEC 61000-4-2 contact ESD immunity, and 13 V reverse clamping voltage at 5 A surge. It protects high-speed data lines such as USB 2.0, HDMI, and SD card interfaces.
For engineers reviewing the VESD05A8A-HNH-GS08 datasheet, VESD05A8A-HNH-GS08 pinout, VESD05A8A-HNH-GS08 application, or VESD05A8A-HNH-GS08 equivalent, key selection criteria include low 0.6 mm profile for space-constrained PCBs, sub-1 μA leakage at 5 V, dual-mode operation (BiAs/BiSy), and validated IEC 61000-4-5 surge handling up to 5 A per line.
Technical Context
The VESD05A8A-HNH-GS08 implements two distinct protection configurations: BiAs-mode uses pin 9 as common ground for eight independent signal-to-ground paths (pins 1–8 → pin 9), delivering asymmetrical clamping (4.5 V forward / 13 V reverse). BiSy-mode repurposes pin 5 as ground and leaves pin 9 unconnected, enabling seven symmetrical bidirectional paths between any two of pins 1–8, with matched ±13 V clamping and reduced 15 pF capacitance at 0 V.
Its LLP1713-9L package features e4-compliant precious-metal terminations, MSL level 1 moisture sensitivity, and UL 94 V-0 molding compound - optimized for reflow compatibility and reliability in consumer and industrial portable electronics where board space and ESD robustness are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VRWM) | 5 V - defines maximum continuous DC voltage on protected lines without leakage degradation |
| Reverse Clamping Voltage (VC) | 13 V at 5 A (IEC 61000-4-5) - limits transient voltage seen by downstream ICs during surge events |
| Capacitance (CD) | 30 pF at 0 V, 18 pF at 2.5 V - ensures minimal signal distortion on USB 2.0 and SDIO interfaces |
| ESD Immunity | ±25 kV contact / ±30 kV air (IEC 61000-4-2) - exceeds Level 4 system-level ESD requirements |
| Leakage Current (IR) | < 0.1 μA at 5 V - prevents battery drain in always-on portable device rails |
| Package | LLP1713-9L - 1.75 × 1.3 mm footprint, 0.6 mm max height, compatible with 0.4 mm pitch routing |
Pinout & Package
LLP1713-9L is a 9-terminal leadless plastic package with exposed thermal pad (DAP), 0.4 mm pitch, and pin 1 marked by dot. Pin 9 serves as common cathode in BiAs-mode; pin 5 acts as ground reference in BiSy-mode. The package supports solder reflow per J-STD-020 MSL level 1 (peak 260 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–8 | Signal input / protected line | Each connects to one data line (e.g., USB D+, D−, SDIO CLK, CMD); configured as anode in BiAs-mode |
| 9 | Common cathode (BiAs-mode) | Ground return path for all eight protection diodes; must be connected to system ground |
| 5 | Ground reference (BiSy-mode) | Used instead of pin 9 when operating in 7-line symmetrical mode; pin 9 left floating |
| DAP (exposed pad) | Thermal and electrical ground | Enhances heat dissipation during surge events and improves grounding integrity when soldered |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile | 0.6 mm max height - enables integration beneath connectors and in ultra-thin mobile designs |
| Dual-mode operation | Configurable as 8-line BiAs or 7-line BiSy - supports both asymmetric logic-level and symmetric analog/data-line protection |
| Precious-metal terminations (e4) | Au/NiPdAu finish - ensures reliable solderability and intermetallic stability over thermal cycling |
| Low dynamic capacitance | 15–30 pF range - preserves signal integrity on 480 Mbps USB 2.0 and 25 MHz SDIO buses |
| High surge robustness | 65 W peak pulse power (BiAs) - withstands repeated 8/20 µs transients without parameter shift |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD8S300ARGER | 8-channel, 5.5 V VRWM, 12 pF @ 0 V, ±15 kV contact ESD, QFN-16 package (2.5 × 2.5 mm) | Lower capacitance but larger footprint and lower ESD rating; requires more PCB area | Prefer when ultra-low capacitance (<15 pF) is prioritized over board space and ESD margin |
| ESDALC6V1-1U2 | 8-channel, 5.5 V VRWM, 20 pF @ 0 V, ±20 kV contact ESD, SOT-1202 (1.7 × 1.3 mm) | Same footprint size but lower ESD rating and higher leakage (≤1 μA vs. ≤0.1 μA) | Choose when cost sensitivity outweighs need for highest ESD immunity and lowest leakage |

FAQ
What is the maximum operating temperature range for the VESD05A8A-HNH-GS08?
The VESD05A8A-HNH-GS08 has a junction temperature range of -40 °C to +125 °C and a storage temperature range of -55 °C to +150 °C. This wide thermal envelope allows deployment in automotive infotainment modules, industrial gateways, and outdoor IoT sensors where ambient conditions exceed standard commercial limits. The LLP1713-9L package's thermal pad enhances heat transfer under sustained surge conditions.
Can the VESD05A8A-HNH-GS08 be used in BiSy-mode for 7-line protection, and what are the pin connections?
Yes, the VESD05A8A-HNH-GS08 supports BiSy-mode for 7-line symmetrical protection: connect pins 1, 2, 3, 4, 6, 7, and 8 to protected signal lines; tie pin 5 to system ground; and leave pin 9 unconnected. In this configuration, each pair of signal pins forms a bidirectional path with matched ±13 V clamping and 15 pF capacitance - ideal for differential buses like RS-485 or MIPI D-PHY lanes.
What is the clamping voltage of the VESD05A8A-HNH-GS08 under IEC 61000-4-5 surge conditions?
The VESD05A8A-HNH-GS08 delivers a reverse clamping voltage (VC) of 13 V at 5 A (8/20 µs waveform) in BiAs-mode and 13 V at 2.5 A in BiSy-mode. Forward clamping is 4.5 V at 5 A. These values are measured per IEC 61000-4-5 and ensure downstream ICs see transient voltages well below their absolute maximum ratings - critical for protecting 3.3 V or 5 V logic interfaces.
Does the VESD05A8A-HNH-GS08 require external biasing or control signals to operate?
No, the VESD05A8A-HNH-GS08 is a passive silicon diode array requiring no external power, bias, or enable signals. It operates purely on voltage threshold behavior: conducting only during overvoltage transients (≥VBR ≈ 6–8 V) while presenting <0.1 μA leakage at normal operating voltage (≤5 V). This zero-bias operation simplifies design and eliminates quiescent current concerns in battery-powered systems.
How does the LLP1713-9L package of the VESD05A8A-HNH-GS08 compare to standard SOT-23 or SC-70 packages in terms of PCB layout?
The LLP1713-9L package of the VESD05A8A-HNH-GS08 measures 1.75 × 1.3 mm with 0.4 mm pin pitch and includes an exposed thermal pad - offering ~40% smaller footprint than SOT-23-8 and ~30% less area than SC-70-8. Its land pattern requires no via-in-pad and supports standard stencil printing; the DAP improves thermal performance without complicating assembly. This makes VESD05A8A-HNH-GS08 ideal for dense, fine-pitch layouts in smartphones and wearables.
