Product details
Overview
VESD05A6A-HAF-GS08 from Vishay Semiconductors is a 6-line bidirectional asymmetrical ESD protection diode array in LLP75-7L package, rated for 5 V working voltage, ±15 kV IEC 61000-4-2 contact/air discharge, 13 pF typical capacitance at 0 V, and <0.1 μA reverse leakage - deployed on high-speed USB 2.0, HDMI, and SD card interfaces to suppress transient overvoltage.
For engineers reviewing the VESD05A6A-HAF-GS08 datasheet, VESD05A6A-HAF-GS08 pinout, VESD05A6A-HAF-GS08 application, or VESD05A6A-HAF-GS08 equivalent, key selection criteria include clamping voltage under 2.5 A pulse (≤13 V), low-load capacitance for signal integrity, MSL level 1 solderability, and BiAs-mode vs. BiSy-mode configuration flexibility.
Technical Context
The VESD05A6A-HAF-GS08 implements a 6-channel unidirectional-to-ground architecture with pin 2 as common cathode and pins 1–6 as protected anodes, enabling BiAs-mode clamping where each line clamps independently to ground. Its asymmetrical behavior delivers 2.0–4.0 V forward clamping and 9–13 V reverse clamping across 1–2.5 A pulses.
In BiSy-mode operation (pin 7 unused), it supports symmetrical line-to-line protection across five channels, with ±10 kV IEC 61000-4-2 rating and reduced channel count. The device uses silicon avalanche diode junctions fabricated in Vishay's e4-compliant precious-metal termination process for stable low-leakage performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VRWM) | 5 V - defines maximum continuous DC operating voltage before leakage rises; matches USB 2.0 and SDIO signaling levels. |
| ESD Rating (IEC 61000-4-2) | ±15 kV contact / ±15 kV air - ensures robust immunity against human-body-model discharges in handheld and portable electronics. |
| Clamping Voltage (VC @ 2.5 A) | ≤13 V reverse - limits peak transient voltage seen by downstream ICs during 8/20 µs surge events. |
| Capacitance (CD @ 0 V) | 13 pF typical - minimizes signal distortion on 480 Mbps USB 2.0 differential pairs and 1.5 Gbps HDMI TMDS lines. |
| Leakage Current (IR @ 5 V) | <0.1 μA - prevents measurable DC loading on battery-powered sensor or audio signal paths. |
| Package | LLP75-7L (1.65 × 1.55 × 0.54 mm) - ultra-compact footprint compatible with fine-pitch PCB layouts and automated SMT assembly. |
| Moisture Sensitivity | MSL level 1 - allows unlimited floor life and standard reflow without baking preconditioning. |
Pinout & Package
LLP75-7L is a 7-pin leadless plastic package with exposed thermal pad, 0.5 mm pitch, and pin 1 marked by dot. Pin 2 serves as common cathode; pins 1, 3–6 are individual anodes; pin 7 is NC in BiAs mode and used as alternate cathode in BiSy mode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode (Channel 1) | Protected I/O line input; clamps to pin 2 during positive transients. |
| Pin 2 | Common Cathode | Ground reference node for all six channels in BiAs configuration; connects to system GND plane. |
| Pin 3 | Anode (Channel 2) | Second protected I/O line; electrically isolated but shares cathode with pin 1. |
| Pin 4 | Anode (Channel 3) | Third protected I/O line; enables compact multi-line protection without discrete diodes. |
| Pin 5 | Anode (Channel 4) | Fourth protected I/O line; maintains ≤13 pF load per channel for high-speed data integrity. |
| Pin 6 | Anode (Channel 5) | Fifth protected I/O line; supports full 6-line protection when pin 7 is unused. |
| Pin 7 | NC / Alternate Cathode | No-connect in BiAs mode; used as cathode for line-to-line clamping in BiSy mode (5-line symmetrical protection). |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 13 pF at 0 V reverse bias - preserves signal rise/fall times on 480 Mbps USB 2.0 and SDIO interfaces. |
| Bidirectional asymmetrical clamping | Forward VF = 2.0–4.0 V / Reverse VC = 9–13 V - provides tighter voltage limiting for positive transients while maintaining safe negative swing margins. |
| Configurable protection modes | BiAs (6-line to GND) or BiSy (5-line line-to-line) - enables layout reuse across different interface topologies without component change. |
| e4-compliant terminations | Precious metal (NiPdAu) finish - eliminates Sn whisker risk and ensures long-term solder joint reliability in automotive and industrial environments. |
| MSL level 1 rating | No floor-life limitation - simplifies inventory management and eliminates pre-reflow baking steps in high-volume manufacturing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD6E05U06DQAR | 6-channel, 5 V VRWM, 0.5 pF lower CD (12.5 pF), same LLP-7 package, but higher IR (0.5 μA max) | Preferred for ultra-low-capacitance USB 3.0 Gen1 auxiliary lanes; less suitable for battery-sensitive low-leakage designs | Select TPD6E05U06DQAR only if sub-13 pF capacitance is critical and leakage tolerance >0.1 μA |
| ESD56031D05-2/TR | 6-channel, 5 V VRWM, 15 pF CD, ±12 kV ESD rating, SOT-26 package (larger footprint, 3× area) | Suitable for cost-driven consumer boards where board space is not constrained and ±12 kV suffices | Choose ESD56031D05-2/TR when LLP75-7L placement is impractical and ±12 kV immunity meets system requirements |
Compared with TPD6E05U06DQAR and ESD56031D05-2/TR, the VESD05A6A-HAF-GS08 offers optimal balance of ultra-low leakage (<0.1 μA), industry-leading ±15 kV rating, and minimal 1.65 × 1.55 mm footprint - making it preferred for space-constrained, battery-operated, and high-reliability ESD protection.

FAQ
What is the maximum clamping voltage of the VESD05A6A-HAF-GS08 under a 2.5 A IEC 61000-4-5 surge?
The VESD05A6A-HAF-GS08 exhibits a maximum reverse clamping voltage (VC) of 13 V when subjected to a 2.5 A 8/20 µs pulse in BiAs-mode (pins 1–6 to pin 2). This value is specified in the Absolute Maximum Ratings table and confirmed in Figure 6 of the official Vishay datasheet (Doc. #81880, Rev. 1.6). The VESD05A6A-HAF-GS08 maintains this clamping performance across its full operating temperature range (-40 °C to +125 °C).
Can the VESD05A6A-HAF-GS08 protect five lines in a symmetrical configuration?
Yes - the VESD05A6A-HAF-GS08 supports bidirectional symmetrical (BiSy) operation by leaving pin 7 unconnected and using pins 1–6 as line-to-line protection paths. In this mode, it protects up to five independent signal pairs with ±10 kV IEC 61000-4-2 immunity. This configuration is explicitly described in the Application Note section of the VESD05A6A-HAF-GS08 datasheet and requires no external components beyond proper PCB grounding.
Is the VESD05A6A-HAF-GS08 compatible with lead-free reflow processes?
Yes - the VESD05A6A-HAF-GS08 is qualified for lead-free reflow with a peak temperature of up to 260 °C, per J-STD-020. Its LLP75-7L package carries MSL level 1 rating, meaning it may be stored indefinitely at ambient conditions without baking. The e4-compliant NiPdAu termination ensures reliable wetting and intermetallic formation during standard SAC305 solder profiles - fully validated for use with the VESD05A6A-HAF-GS08.
What is the reverse leakage current specification for the VESD05A6A-HAF-GS08 at 5 V?
The VESD05A6A-HAF-GS08 specifies a maximum reverse leakage current (IR) of 0.1 μA at VR = 5 V and Tamb = 25 °C, with typical value <0.01 μA. This ultra-low leakage is critical for preserving battery life in always-on sensor nodes and avoiding false triggering in high-impedance analog monitoring circuits. The value is measured per channel and confirmed in the Electrical Characteristics table of the official Vishay datasheet for VESD05A6A-HAF-GS08.
Does the VESD05A6A-HAF-GS08 require external biasing or control signals?
No - the VESD05A6A-HAF-GS08 is a passive, unidirectional ESD protection array requiring no external power, biasing, or control logic. It operates solely via avalanche breakdown of integrated silicon diodes during overvoltage events. All functionality - including BiAs and BiSy modes - is determined solely by PCB routing (e.g., connection of pin 2 to GND or leaving pin 7 floating). No firmware, drivers, or configuration registers are associated with the VESD05A6A-HAF-GS08.
