Product details
Overview
VESD05A5A-HSF-GS08 from Vishay Semiconductors is a 5-line bidirectional asymmetrical ESD protection diode array in LLP75-6L package, rated for 5 V working voltage (VRWM), 13 pF line capacitance at 0 V, <0.1 μA reverse leakage, ±15 kV IEC 61000-4-2 contact/air discharge, and 12–13 V clamping at 2.5 A peak pulse current - deployed on high-speed USB, HDMI, and audio interface lines.
For engineers reviewing the VESD05A5A-HSF-GS08 datasheet, VESD05A5A-HSF-GS08 pinout, VESD05A5A-HSF-GS08 application, or VESD05A5A-HSF-GS08 equivalent, key selection criteria include low-profile 0.6 mm height, MSL level 1 solderability, e4-compliant precious-metal terminations, and verified BiAs-mode clamping performance across five independent signal paths.
Technical Context
The VESD05A5A-HSF-GS08 implements a 5-channel discrete diode array with dedicated ground reference (pin 2) and five protected I/O pins (1, 3–6), enabling bidirectional asymmetrical (BiAs) clamping where forward VF ≈ 2–4 V and reverse VC ≈ 9–13 V under ESD stress. Its architecture supports both single-line-to-ground and inter-line (BiSy) protection modes.
Clamping behavior is defined by silicon junction characteristics: reverse breakdown VBR = 6–7.5 V at 1 mA, with VRWM = 5 V ensuring compatibility with 3.3 V/5 V logic rails. Capacitance drops from 13 pF @ 0 V to 8 pF @ 2.5 V reverse bias - critical for preserving signal integrity on >100 MHz data lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VRWM) | 5 V - matches standard 5 V I/O rail; ensures no conduction during normal operation. |
| ESD Rating (IEC 61000-4-2) | ±15 kV contact / ±15 kV air - exceeds industrial immunity requirements for handheld and peripheral interfaces. |
| Line Capacitance (CD) | 13 pF @ 0 V - low enough for USB 2.0 (480 Mbps) and HDMI 1.4 signal fidelity without added jitter. |
| Reverse Leakage (IR) | < 0.1 μA @ 5 V - negligible power drain on battery-powered sensor or audio I/O circuits. |
| Clamping Voltage (VC) | 12–13 V @ 2.5 A - limits transient overvoltage to safe levels for downstream 5 V-tolerant transceivers. |
| Package | LLP75-6L - 1.65 × 1.05 × 0.6 mm, MSL level 1, compatible with standard reflow profiles up to 260 °C. |
| Operating Temp | −40 to +125 °C - qualified for automotive infotainment and industrial control ambient conditions. |
Pinout & Package
LLP75-6L is a 6-pin leadless plastic package with exposed thermal pad, 0.6 mm max height, and e4-compliant NiPdAu terminations. Pin 1 marked by dot; pin 2 is common cathode/anode ground reference.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | I/O Line 1 (anode in BiAs mode) | Protected signal path; clamps to pin 2 during positive ESD events. |
| Pin 2 | Common Ground Reference | Shared cathode connection for all five channels; must be connected to system ground for BiAs operation. |
| Pin 3 | I/O Line 2 (anode in BiAs mode) | Second independent protected line; electrically isolated from other I/O pins. |
| Pin 4 | I/O Line 3 (anode in BiAs mode) | Third protected line; identical clamping characteristics as pins 1 and 3. |
| Pin 5 | I/O Line 4 (anode in BiAs mode) | Fourth protected line; validated for ≤13 pF loading on high-speed traces. |
| Pin 6 | I/O Line 5 (anode in BiAs mode) | Fifth protected line; enables full 5-line protection without external components. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile | 0.6 mm max height - enables use in space-constrained mobile and wearable PCBs. |
| Low load capacitance | 13 pF @ 0 V - preserves edge rate and eye diagram integrity on USB/HDMI lines. |
| Bidirectional asymmetrical clamping | VF ≈ 2–4 V (forward), VC ≈ 9–13 V (reverse) - protects both positive and negative transients while minimizing forward conduction loss. |
| e4-compliant terminations | NiPdAu surface finish - eliminates Sn whisker risk and ensures long-term solder joint reliability. |
| MSL level 1 rating | No floor life limitation - simplifies SMT handling and eliminates bake requirements pre-reflow. |
Applications
| USB 2.0 Interface Protection | HDMI DDC/CEC Line Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E05U06DQAR | 4-channel, 0.5 pF lower CD (12.5 pF), same VRWM (5 V), but only ±12 kV IEC 61000-4-2 contact rating. | Optimized for ultra-high-speed USB 3.0/PCIe; lacks fifth channel - requires additional device for 5-line coverage. | Select when prioritizing lowest possible capacitance over channel count or ESD margin. |
| SZ1.5SMC5.0AT3G | Single-channel 5 V TVS, 600 W peak power, 100 pF CD - significantly higher capacitance and larger SMC package (7.1 × 6.2 mm). | Used in board-level surge protection; unsuitable for multi-line high-speed interfaces due to size and capacitance. | Choose only for cost-sensitive, low-frequency, single-line applications where layout area and signal integrity are secondary. |
Compared with TPD4E05U06DQAR and SZ1.5SMC5.0AT3G, the VESD05A5A-HSF-GS08 uniquely delivers five matched low-capacitance channels in a 1.65 mm × 1.05 mm footprint with ±15 kV ESD immunity - making it the only option that satisfies compact, multi-signal, high-immunity requirements without compromising signal fidelity.

FAQ
What is the maximum clamping voltage of the VESD05A5A-HSF-GS08 during an ESD event?
The VESD05A5A-HSF-GS08 exhibits a maximum reverse clamping voltage (VC) of 13 V at 2.5 A peak pulse current (IPPM) in BiAs-mode (pin 1–6 to pin 2). This value is measured per IEC 61000-4-5 8/20 µs waveform and ensures downstream 5 V logic remains within safe overvoltage limits during transient events. The VESD05A5A-HSF-GS08 maintains this clamping performance across its full operating temperature range.
Can the VESD05A5A-HSF-GS08 protect more than five signal lines?
No - the VESD05A5A-HSF-GS08 is designed for exactly five independent signal lines (pins 1 and 3–6) referenced to a common ground (pin 2). While Application Note section b describes a BiSy-mode configuration using four lines with pin 2 unconnected, this does not increase channel count beyond five and sacrifices the specified ±15 kV BiAs-mode rating. The VESD05A5A-HSF-GS08 cannot protect six or more lines simultaneously.
Is the VESD05A5A-HSF-GS08 compatible with lead-free reflow processes?
Yes - the VESD05A5A-HSF-GS08 is qualified for lead-free reflow with a peak temperature limit of 260 °C, per J-STD-020 MSL level 1 classification. Its LLP75-6L package uses e4-compliant NiPdAu terminations, eliminating tin-based finishes and mitigating whisker formation risks. The VESD05A5A-HSF-GS08 requires no pre-bake and supports standard industry reflow profiles.
How does the capacitance of the VESD05A5A-HSF-GS08 vary with applied voltage?
The VESD05A5A-HSF-GS08 line capacitance decreases with increasing reverse bias: 13 pF at 0 V, dropping to 8 pF at 2.5 V reverse voltage (f = 1 MHz). This voltage-dependent behavior results from junction depletion widening and is documented in Figure 3 of the official datasheet. The VESD05A5A-HSF-GS08's capacitance profile helps maintain signal integrity on biased high-speed lines such as HDMI DDC.
Does the VESD05A5A-HSF-GS08 meet automotive AEC-Q200 requirements?
No - the VESD05A5A-HSF-GS08 is not AEC-Q200 qualified. It is rated for −40 to +125 °C operating temperature and meets IEC 61000-4-2/4-5 standards, but Vishay does not list AEC-Q200 qualification in the Rev. 1.7 datasheet (Document Number: 81655). For automotive-grade ESD protection, designers should verify alternate Vishay parts explicitly marked AEC-Q200, as the VESD05A5A-HSF-GS08 is intended for industrial and consumer applications.
