Product details
Overview
VESD05A6-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 (VRWM), ±30 kV IEC 61000-4-2 contact/air discharge immunity, and 40 pF line capacitance at 0 V bias - deployed for high-speed USB 2.0, HDMI, and MIPI data line protection.
For engineers reviewing the VESD05A6-HAF-GS08 datasheet, VESD05A6-HAF-GS08 pinout, VESD05A6-HAF-GS08 application, or VESD05A6-HAF-GS08 equivalent, key selection criteria include clamping voltage at 5 A (≤12 V), leakage current (<1 μA), MSL level 1 solderability, and BiAs-mode configuration enabling independent 6-line protection to ground (pin 2) or symmetrical 5-line operation with pin 7 unconnected.
Technical Context
The VESD05A6-HAF-GS08 implements a bidirectional asymmetrical (BiAs) clamping architecture: each of pins 1–6 provides separate ESD paths to pin 2 (ground) with forward clamping ~3.2 V and reverse clamping ~11.3 V at 5 A, while pin 7 serves as an optional common cathode for symmetrical 5-line operation. It is not a unidirectional or TVS-only device.
Its electrical behavior is defined by dual clamping thresholds (VF ≈ 1.5–4.5 V forward, VC ≈ 8.1–12 V reverse), low 40 pF capacitance at 0 V enabling <480 Mbps signal integrity, and guaranteed operation from –40 °C to +125 °C junction temperature - all validated per IEC 61000-4-2 and IEC 61000-4-5 standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VRWM) | 5 V - sets maximum continuous DC operating voltage before leakage rises significantly; matches standard 3.3 V/5 V logic rails. |
| ESD Immunity | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - exceeds industrial and consumer ESD requirements without external circuit derating. |
| Clamping Voltage (VC) | ≤12 V at 5 A peak pulse (IEC 61000-4-5) - ensures protected ICs see sub-12 V transient stress during surge events. |
| Line Capacitance (CD) | 40 pF at 0 V, 24 pF at 2.5 V - preserves signal rise/fall times for USB 2.0 (480 Mbps) and MIPI D-PHY interfaces. |
| Leakage Current (IR) | <0.1 μA typical at 5 V - avoids measurable DC loading on high-impedance data lines like I²C or GPIO. |
| Package | LLP75-7L (1.65 × 1.55 × 0.54 mm) - ultra-compact footprint with MSL level 1 reflow compatibility up to 260 °C. |
Pinout & Package
LLP75-7L is a 7-pin leadless plastic package with exposed heat sink pad (pin 2), 0.5 mm pitch, and pin 1 marked by dot. Dimensions: 1.65 mm × 1.55 mm × 0.54 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | ESD Protection Input (Line 1) | Independent bidirectional ESD path to pin 2; clamps both positive and negative transients to ground. |
| Pin 2 | Ground / Heat Sink Pad | Common ground terminal and thermal interface; must be soldered to PCB ground plane for thermal and ESD performance. |
| Pin 3 | ESD Protection Input (Line 2) | Second independent BiAs protection channel; electrically isolated from other lines. |
| Pin 4 | ESD Protection Input (Line 3) | Third dedicated ESD input; supports simultaneous multi-line protection without crosstalk coupling. |
| Pin 5 | ESD Protection Input (Line 4) | Fourth protected line; same clamping characteristics as pins 1–4. |
| Pin 6 | ESD Protection Input (Line 5) | Fifth protected line; enables full 5-line symmetrical mode when pin 7 is left open. |
| Pin 7 | Common Cathode Terminal | Enables symmetrical 5-line operation (pins 1–6 excluding one); must remain unconnected for standard 6-line BiAs mode. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Asymmetrical Clamping (BiAs) | Enables independent 6-line protection with optimized forward/reverse clamping - no external bias required. |

IC Role / Device Role: General-purpose 6-line protector supporting mixed-signal routing with shared ground reference (pin 2). Use Value: –40 °C to +125 °C operation ensures reliability across extended industrial temperature range without derating. |
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 LLP-7 package but different pinout (pin 2 = VCC, not GND) | Requires VCC connection; unsuitable for ground-referenced BiAs mode without redesign | Select only if system has stable 3.3–5 V supply near connector and layout supports VCC routing. |
| SP3205-01HTG | 6-line, 5 V VRWM, higher CD (65 pF), SOT-23-6 package (larger, 3.0 × 1.75 mm), unidirectional configuration | Lacks BiAs capability; requires external bias for bidirectional protection; incompatible with pin-for-pin replacement | Use only when space allows larger footprint and application tolerates higher capacitance and unidirectional clamping. |
Compared with TPD6E05U06DQAR and SP3205-01HTG, the VESD05A6-HAF-GS08 delivers true ground-referenced 6-line BiAs protection in the smallest footprint (1.65 × 1.55 mm), with lowest design integration effort for USB/HDMI/MIPI interfaces requiring zero-VCC dependency and minimal layout change.

FAQ
What is the exact pin configuration and grounding requirement for VESD05A6-HAF-GS08?
The VESD05A6-HAF-GS08 uses a 7-pin LLP75-7L package with pin 2 as the mandatory ground/heat sink pad. Pins 1–6 serve as independent ESD inputs, each clamping to pin 2. Pin 7 is a common cathode used only in symmetrical 5-line mode and must remain unconnected for standard 6-line BiAs operation. The ground pad (pin 2) must be soldered to a solid PCB ground plane for optimal thermal dissipation and ESD performance.
Does VESD05A6-HAF-GS08 support bidirectional or unidirectional ESD protection?
The VESD05A6-HAF-GS08 supports bidirectional asymmetrical (BiAs) protection by default: each of pins 1–6 clamps both positive and negative transients to ground (pin 2) with different forward/reverse thresholds. It can also operate in symmetrical bidirectional mode protecting five lines when pin 7 is left unconnected - but it does not function as a unidirectional device unless externally biased, which is not recommended per Vishay's application note.
What is the maximum data rate supported by VESD05A6-HAF-GS08 without signal distortion?
The VESD05A6-HAF-GS08 supports up to 480 Mbps (USB 2.0 full-speed) with negligible signal distortion due to its 40 pF capacitance at 0 V bias and 24 pF at 2.5 V. Measured eye diagrams confirm compliance with USB 2.0 electrical specifications when placed within 5 mm of the connector. For higher-rate interfaces like USB 3.0 or PCIe, a lower-capacitance solution is required.
How does the clamping behavior of VESD05A6-HAF-GS08 differ between forward and reverse polarity?
In BiAs mode, VESD05A6-HAF-GS08 clamps forward transients (anode-to-cathode) at ~3.2 V (typ.) and reverse transients (cathode-to-anode) at ~11.3 V (typ.) when stressed with 5 A pulses. This asymmetry allows low-voltage logic lines to benefit from tight forward clamping while maintaining robust reverse standoff - unlike symmetrical TVS diodes that clamp equally in both directions.
Is VESD05A6-HAF-GS08 compliant with automotive AEC-Q200 or industrial reliability standards?
The VESD05A6-HAF-GS08 is not AEC-Q200 qualified, but it meets industrial-grade reliability requirements: operating junction temperature range of –40 °C to +125 °C, MSL level 1 per J-STD-020, and UL 94 V-0 flammability rating. Vishay specifies it for industrial, computing, and consumer applications - not for under-hood automotive use unless separately validated by the end customer.
