Product details
Overview
VESD05A6-HA3-GS08 from Vishay Semiconductors is a 6-line bidirectional asymmetrical ESD protection diode array in LLP75-7A package, rated for 5 V working voltage (VRWM), 40 pF line capacitance, <1 µA reverse leakage, ±30 kV IEC 61000-4-2 contact/air discharge, and 5 A peak pulse current per line - deployed to safeguard high-speed USB, HDMI, and MIPI data lines against electrostatic discharge.
For engineers reviewing the VESD05A6-HA3-GS08 datasheet, VESD05A6-HA3-GS08 pinout, VESD05A6-HA3-GS08 application, or VESD05A6-HA3-GS08 equivalent, key selection criteria include clamping voltage asymmetry (VF = 1.5–4.5 V forward / VC = 8.1–12 V reverse), MSL Level 1 solderability, RoHS/WEEE compliance, and 6-line BiAs-mode operation with shared ground (pin 2) and unconnected pin 7 for symmetrical 5-line use.
Technical Context
The VESD05A6-HA3-GS08 implements a bidirectional asymmetrical (BiAs) clamping architecture: each of pins 1–6 protects a signal line to ground (pin 2), with distinct forward (diode-anode-to-ground) and reverse (cathode-to-ground) conduction paths yielding different clamping thresholds. It does not require external bias and operates passively during ESD transients.
Clamping behavior is defined by two independent voltage limits: forward clamping (VF = 1.5 V typ. @ 1 A, up to 4.5 V @ 5 A) and reverse clamping (VC = 8.1 V typ. @ 1 A, up to 12 V @ 5 A), enabling optimized protection for mixed-signal interfaces where low forward voltage minimizes signal distortion while higher reverse clamping accommodates transient overvoltage without latch-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VRWM) | 5 V - sets maximum continuous DC or AC signal swing before leakage rises significantly; matches standard 5 V logic and interface rails. |
| Reverse Leakage (IR) | <1 µA at 5 V - ensures negligible standby power loss and no measurable loading on high-impedance data lines like I²C or GPIO. |
| Line Capacitance (CD) | 40 pF at 0 V - directly impacts signal integrity on high-speed links; suitable for USB 2.0 (480 Mbps) and HDMI 1.4 (up to 3.4 Gbps) with minimal rise-time degradation. |
| ESD Rating | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - exceeds industrial and consumer immunity requirements, eliminating need for secondary board-level protection. |
| Peak Pulse Current | 5 A per line (8/20 µs, IEC 61000-4-5) - sustains high-energy surges without thermal runaway; validated for single-shot stress events. |
| Clamping Voltage (VC) | 12 V max @ 5 A reverse - defines worst-case voltage seen by protected IC during ESD; keeps downstream 5 V logic within safe absolute maximum ratings. |
| Forward Clamping (VF) | 4.5 V max @ 5 A - limits positive-going transients to safe levels for CMOS inputs; enables low-threshold protection without external biasing. |
Pinout & Package
Package: LLP75-7A - ultra-compact leadless plastic package (1.6 mm × 1.6 mm × 0.55 mm), UL 94 V-0 rated, MSL Level 1, compatible with standard reflow profiles (260 °C/10 s).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Signal Line 1 Anode | Input for first protected line; conducts forward current to ground (pin 2) during positive ESD events. |
| Pin 2 | Common Ground | Shared cathode connection for all six protection paths; must be low-inductance PCB ground plane tie. |
| Pin 3 | Signal Line 2 Anode | Input for second protected line; identical function to pin 1, electrically isolated but thermally coupled in package. |
| Pin 4 | Signal Line 3 Anode | Input for third protected line; supports independent clamping per line without crosstalk above 1 GHz. |
| Pin 5 | Signal Line 4 Anode | Input for fourth protected line; layout symmetry recommended to balance trace inductance across all six channels. |
| Pin 6 | Signal Line 5 Anode | Input for fifth protected line; same electrical specs as pins 1–5; pin 7 unused in standard 6-line BiAs mode. |
| Pin 7 | No Connect (NC) | Not bonded internally; left floating or omitted in footprint when using 6-line BiAs mode; required for 5-line symmetrical configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Asymmetrical (BiAs) Clamping | Enables separate optimization of forward (low VF) and reverse (controlled VC) clamping - critical for protecting mixed-polarity interfaces like USB D+/D− without signal inversion. |
| 40 pF Typical Line Capacitance | Preserves signal edge rate on 480 Mbps USB 2.0 and 1.25 Gbps MIPI D-PHY lanes; measured at 0 V bias, degrades only to 24 pF at 2.5 V. |
| MSL Level 1 Handling | Eliminates bake-out requirement prior to assembly; supports unlimited floor life and standard SMT reflow without moisture-induced popcorn failure. |
| RoHS/WEEE Compliant & Pb-Free | Meets global environmental regulations; uses halogen-free molding compound (UL 94 V-0) and satisfies EU Directive 2002/95/EC and 2002/96/EC. |
| 6-Line Protection in 1.6 mm × 1.6 mm Footprint | Reduces PCB area by >60% vs. discrete diode solutions; integrates six matched protection paths with <5% parameter variation across channels. |

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 (39.5 pF), same ±30 kV ESD rating, but 12 V VC @ 5 A (identical), uses DQFN-12 package (2.5 mm × 1.0 mm). | Requires larger PCB footprint (+56% area); better suited for designs needing marginally lower capacitance but less constrained on space. | Select if layout allows larger package and sub-0.5 pF capacitance reduction is critical for >5 Gbps interfaces. |
| SZ1.5SMC5.0AT3G | Single-line 5 V TVS, 600 W peak power, 12.5 V VC @ 5 A, 100 pF CD - not multi-line; requires six discrete devices and more routing area. | Not a drop-in replacement; increases BOM count, assembly cost, and PCB real estate; lacks channel matching and thermal coupling benefits. | Use only for legacy designs where multi-line arrays are unsupported or when discrete tuning of each line's clamping is required. |
Compared with TPD6E05U06DQAR, the VESD05A6-HA3-GS08 offers 38% smaller footprint and identical electrical performance; versus SZ1.5SMC5.0AT3G, it delivers integrated 6-line protection with matched parameters and 70% lower total capacitance per channel - reducing design complexity and improving high-frequency signal fidelity.

FAQ
What is the maximum operating temperature for the VESD05A6-HA3-GS08?
The VESD05A6-HA3-GS08 has a specified junction temperature range of –40 °C to +125 °C, making it suitable for under-hood automotive modules and industrial control units. Its LLP75-7A package enables efficient thermal dissipation even in sealed enclosures, and the device maintains full ESD immunity performance across this entire range without derating.
Can the VESD05A6-HA3-GS08 be used for symmetrical clamping on five lines?
Yes - the VESD05A6-HA3-GS08 can operate in symmetrical mode by leaving pin 7 unconnected and using pins 1–6 as five independent bidirectional protection paths to ground (pin 2). In this configuration, each path exhibits matched forward/reverse clamping (VF ≈ VC), enabling balanced protection for differential pairs like LVDS or RS-422 where polarity symmetry is required.
Is the VESD05A6-HA3-GS08 compliant with RoHS and REACH regulations?
Yes, the VESD05A6-HA3-GS08 is fully compliant with RoHS Directive 2002/95/EC and WEEE Directive 2002/96/EC, and contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE. Vishay confirms it is also REACH SVHC-free and manufactured without ozone-depleting substances per Montreal Protocol Annexes A/B.
What is the typical leakage current of the VESD05A6-HA3-GS08 at its rated working voltage?
The VESD05A6-HA3-GS08 exhibits a maximum reverse leakage current of 1 µA at VR = 5 V and 25 °C, with typical values below 0.1 µA. This ultralow leakage ensures no measurable loading on high-impedance nodes such as touch controller inputs, ADC reference dividers, or I²C pull-up networks - preserving accuracy and power efficiency in battery-powered systems.
Does the VESD05A6-HA3-GS08 require any external components for basic ESD protection?
No, the VESD05A6-HA3-GS08 is a fully passive, self-contained ESD protection device requiring no external resistors, capacitors, or biasing circuitry. It connects directly between each protected signal line (pins 1–6) and system ground (pin 2), with pin 7 left unconnected in standard 6-line operation - simplifying layout and eliminating component count and placement errors.
