Product details
Overview
VESD05A1C-HD1-GS08 from Vishay Semiconductors is a bidirectional asymmetrical ESD protection diode in LLP1006-2L package, rated for 5 V reverse stand-off voltage (VRWM), 38 pF capacitance at 2.5 V, ±30 kV IEC 61000-4-2 contact/air discharge, and 8 A peak pulse current per IEC 61000-4-5 - deployed on high-speed USB 2.0 data lines.
For engineers reviewing the VESD05A1C-HD1-GS08 datasheet, VESD05A1C-HD1-GS08 pinout, VESD05A1C-HD1-GS08 application, or VESD05A1C-HD1-GS08 equivalent, key selection criteria include clamping asymmetry (VF ≈ 1.1 V / VC ≈ 9.3 V @ 8 A), ultra-low profile (<0.4 mm height), MSL Level 1 solderability, and e4 NiPdAu plating for whisker-free reliability in space-constrained portable electronics.
Technical Context
The VESD05A1C-HD1-GS08 implements BiAs-mode (bidirectional asymmetrical) protection: pin 1 grounded, pin 2 connected to signal line; forward clamping (negative transients) occurs near ground via low VF (~1.1 V @ 1 A), while reverse clamping (positive transients) activates above VRWM = 5 V with VC = 9.3 V @ 8 A.
Its 38 pF load capacitance at VR = 2.5 V and <0.2 μA leakage at VR = 5 V enable compatibility with 480 Mbps USB 2.0 signaling without signal integrity degradation; the LLP1006-2L package supports automated optical inspection without X-ray due to visible cathode bar marking and flat top surface.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Protection Type | Bidirectional asymmetrical (BiAs): distinct VF and VC clamping for +/− transients |
| VRWM | 5 V - maximum continuous working voltage before conduction begins |
| CD @ 2.5 V | 38 pF - minimal signal loading on USB 2.0 or HDMI DDC lines |
| IR @ 5 V | ≤0.2 μA - negligible standby power loss in battery-powered systems |
| VC @ 8 A | ≤10 V - robust clamping under worst-case IEC 61000-4-5 surge |
| ESD Rating | ±30 kV contact/air (IEC 61000-4-2) - exceeds industrial immunity requirements |
| Package | LLP1006-2L: 1.05 × 0.65 × 0.4 mm, MSL Level 1, NiPdAu (e4) plating |
Pinout & Package
LLP1006-2L is a 2-terminal leadless plastic package with exposed pad (no thermal pad connection), 0.4 mm max height, and cathode marked by a bar on pin 1 side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (ground reference) | Connected directly to system ground plane; defines return path for transient current |
| Pin 2 | Anode (signal line interface) | Connected to protected data line (e.g., USB D+); conducts negative transients forward, positive transients in reverse breakdown |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile | 0.4 mm max height enables use in <0.8 mm total PCB stack-up mobile designs |
| BiAs clamping behavior | Asymmetric response: VF ≈ 1.1 V (−transient) / VC ≈ 9.3 V (+transient) @ 8 A improves noise margin vs. symmetrical diodes |
| Optical inspection ready | Cathode bar marking and flat top surface allow 100% AOI verification without X-ray |
| e4 NiPdAu plating | Whisker-free termination compatible with Pb-free reflow and long-term storage |
| MSL Level 1 rating | No floor life limitation; safe for standard SMT assembly without dry pack or baking |
Applications
| USB 2.0 Interface Protection | HDMI DDC Line Protection |
|---|---|
Use Scenario: Protecting D+ and D− lines of USB 2.0 ports against ESD events during hot-plug insertion in smartphones and tablets. IC Role / Device Role / Timing Role: Standalone ESD suppressor placed immediately at connector, operating in BiAs mode to clamp both polarities with minimal signal distortion. Use Value: 38 pF capacitance ensures <1% signal rise-time degradation at 480 Mbps; ±30 kV rating covers IEC 61000-4-2 compliance without additional TVS stages. |

IC Role / Device Role / Timing Role: Primary front-end transient suppressor on differential data lines, leveraging asymmetrical clamping to preserve common-mode range. Use Value: 8 A IEC 61000-4-5 surge rating handles induced surges from nearby motor switching; MSL Level 1 simplifies manufacturing logistics. |
Use Scenario: Protecting USB host ports in automotive head units against ESD from passenger interaction in high-temperature cabins (−40 °C to +125 °C TJ). IC Role / Device Role / Timing Role: Automotive-grade ESD diode qualified per AEC-Q101, mounted at USB connector with direct ground tie to chassis. Use Value: Junction temperature range (−40 to +125 °C) ensures operation across full vehicle thermal envelope; e4 plating resists corrosion in humid environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | Unidirectional, 5.5 V VRWM, 15 pF @ 0 V, 1.2 A IPP | Limited to single-polarity transients; lower capacitance but no negative-transient clamping | Select when only positive ESD events dominate and lowest possible CD is critical (e.g., RF antenna lines) |
| SZ1.5SMC5.0AT3G | Unidirectional, 5.0 V VRWM, 250 pF @ 0 V, 150 A IPP, DO-214AB package | High-capacitance, high-power, through-hole - unsuitable for high-speed data lines | Choose only for low-frequency power rail protection where board space and speed are not constraints |
Compared with TPD2E001DRYR and SZ1.5SMC5.0AT3G, the VESD05A1C-HD1-GS08 uniquely delivers bidirectional asymmetrical clamping in an ultra-compact 1.05 mm × 0.65 mm footprint with optimized 38 pF capacitance - making it the only viable option for space-limited, high-speed digital interfaces requiring full ±30 kV ESD immunity.

FAQ
What is the clamping voltage of VESD05A1C-HD1-GS08 under an 8 A IEC 61000-4-5 surge?
The VESD05A1C-HD1-GS08 exhibits a maximum reverse clamping voltage (VC) of 10 V at 8 A peak pulse current per IEC 61000-4-5 testing. This value is measured under 8/20 μs waveform conditions and ensures downstream ICs remain within safe operating voltage limits during surge events. The VESD05A1C-HD1-GS08 achieves this with minimal voltage overshoot due to its low dynamic impedance.
Does VESD05A1C-HD1-GS08 support automated optical inspection (AOI) without X-ray?
Yes, the VESD05A1C-HD1-GS08 supports full AOI verification thanks to its LLP1006-2L package features: a visible cathode bar marking on pin 1 side and a flat, uniform top surface. Vishay explicitly states that solder joint quality can be confirmed using standard vision inspection systems - eliminating the need for X-ray equipment in production line quality control for the VESD05A1C-HD1-GS08.
What is the maximum operating temperature range for VESD05A1C-HD1-GS08?
The VESD05A1C-HD1-GS08 is rated for junction temperatures from −40 °C to +125 °C, enabling reliable operation in extended environmental conditions such as automotive cabin electronics or industrial control enclosures. This range is validated per the absolute maximum ratings table in the official Vishay datasheet (Document Number: 81798, Rev. 1.9), and applies directly to the VESD05A1C-HD1-GS08 device.
How does the BiAs-mode operation of VESD05A1C-HD1-GS08 differ from standard bidirectional ESD diodes?
Unlike symmetrical bidirectional diodes, the VESD05A1C-HD1-GS08 uses BiAs-mode: it clamps negative transients in forward bias (VF ≈ 1.1 V @ 1 A) and positive transients in reverse breakdown (VC ≈ 9.3 V @ 8 A). This asymmetry preserves signal integrity on data lines referenced to ground, reduces ground bounce, and avoids false triggering - a key distinction confirmed in the VESD05A1C-HD1-GS08 datasheet's functional description section.
Is VESD05A1C-HD1-GS08 compliant with RoHS and halogen-free standards?
Yes, the VESD05A1C-HD1-GS08 meets RoHS Directive 2011/65/EU and is halogen-free per Vishay's material categorization standard (Document Number: 99912). Its LLP1006-2L molding compound carries UL 94 V-0 flammability rating, and the NiPdAu (e4) terminal plating contains no tin or whisker-prone materials - all verified in the official VESD05A1C-HD1-GS08 product documentation.
