Product details
Overview
VESD05A1B-HD1-GS08 from Vishay Semiconductors is a bidirectional asymmetrical (BiAs) ESD protection diode in LLP1006-2L package, designed for single-line signal/data-line protection with 5 V reverse standoff voltage, ±30 kV IEC 61000-4-2 ESD immunity, and 12 pF load capacitance at 2.5 V - deployed in USB 2.0, HDMI, and portable audio interfaces.
For engineers reviewing the VESD05A1B-HD1-GS08 datasheet, VESD05A1B-HD1-GS08 pinout, VESD05A1B-HD1-GS08 application, or VESD05A1B-HD1-GS08 equivalent, key selection criteria include clamping voltage asymmetry (VF ≈ 0.95 V forward / VC ≈ 8 V at 1 A reverse), ultra-low profile (<0.4 mm height), MSL Level 1 solderability, NiPdAu (e4) plating, and 1-line BiAs topology for high-speed data line protection.
Technical Context
The VESD05A1B-HD1-GS08 implements bidirectional asymmetrical clamping: forward conduction clamps negative transients near ground (VF ≤ 1.2 V at 0.2 A), while reverse breakdown (VBR = 6–7.5 V) and clamping (VC ≤ 9.5 V at 1 A) protect positive surges. Its 12 pF capacitance at 2.5 V enables <100 Mbps signal integrity on 50 Ω lines.
It operates across –40 °C to +125 °C junction temperature, withstands 3 A (8/20 μs) surge per IEC 61000-4-5, and features UL 94 V-0 molding compound with MSL Level 1 handling - eliminating bake requirements and enabling standard reflow up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Protection Type | Bidirectional asymmetrical (BiAs): low VF clamps negative transients near 0 V; controlled VC clamps positive transients at ≤9.5 V (1 A) |
| Reverse Standoff Voltage | 5 V - maximum continuous working voltage before leakage exceeds 0.1 μA; sets upper limit for protected data-line DC bias |
| ESD Immunity | ±30 kV contact & air discharge (IEC 61000-4-2) - exceeds industrial and consumer immunity requirements without external filtering |
| Load Capacitance | 12 pF at VR = 2.5 V, 1 MHz - preserves signal rise/fall times in USB 2.0 (480 Mbps) and HDMI 1.4 (3.4 Gbps) applications |
| Peak Pulse Current | 3 A (8/20 μs, IEC 61000-4-5) - handles lightning-induced surges and system-level coupling events in handheld and automotive infotainment |
| Package Height | <0.4 mm - enables integration beneath thin-film shields and in space-constrained mobile PCBs with stacked flex assemblies |
Pinout & Package
LLP1006-2L: 2-terminal ultra-compact leadless plastic package (1.05 × 0.65 × 0.33 mm), cathode-marked top-side bar, NiPdAu (e4) terminations, MSL Level 1, UL 94 V-0 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Ground connection | Low-inductance return path for ESD current; must be tied directly to solid ground plane with minimal trace length |
| Pin 2 | Protected signal/data line | Connected in series between IC I/O and connector; clamps transients to ground via BiAs conduction paths |
Key Features
| Feature | Design Value |
|---|---|
| BiAs clamping architecture | Enables simultaneous low-voltage negative clamping (VF ≤ 1.2 V) and controlled positive clamping (VC ≤ 9.5 V), minimizing signal distortion on bidirectional buses |
| Ultra-low capacitance (12 pF @ 2.5 V) | Preserves signal integrity in high-speed interfaces (e.g., USB 2.0 eye diagram margin ≥ 30% at 480 Mbps) |
| 0.33 mm max package height | Supports mechanical stacking under metal shields and compatibility with automated optical inspection (AOI) without X-ray |
| e4 NiPdAu plating | Eliminates tin whisker risk and ensures long-term solder joint reliability in thermal cycling environments (–40/+125 °C) |
Applications
| USB 2.0 Data Lines | HDMI DDC/CEC Channels |
|---|---|
Use Scenario: Protecting D+ and D– lines of USB 2.0 ports against ESD during hot-plug insertion in smartphones and docking stations. IC Role / Device Role / Timing Role: Single-line BiAs ESD clamp placed immediately adjacent to USB connector, with Pin 1 grounded and Pin 2 on signal path. Use Value: Maintains 480 Mbps data rate by limiting load capacitance to 12 pF and clamping transients within ±30 kV without signal overshoot or jitter degradation. |
Use Scenario: Safeguarding HDMI DDC (I²C) and CEC control lines from user-handling ESD in TVs, set-top boxes, and AV receivers. IC Role / Device Role / Timing Role: Low-leakage (IR ≤ 0.1 μA) protector on 5 V-tolerant I²C bus, preserving pull-up resistor bias and clock stretching timing. Use Value: Prevents I²C bus lockup and CEC command loss by clamping negative transients to ≤1.2 V and positive transients to ≤9.5 V at 1 A. |
| Portable Audio Jacks | Automotive Infotainment Displays |
Use Scenario: Shielding 3.5 mm TRRS audio jack contacts (MIC, L/R, GND) from ESD in headphones and earbuds. IC Role / Device Role / Timing Role: One-device-per-signal-line protection with ground-referenced topology; each VESD05A1B-HD1-GS08 guards one analog audio path. Use Value: Ensures no audible pop or DC offset shift due to sub-1.2 V forward clamping and <0.1 μA leakage at 3.3 V bias. |
Use Scenario: Protecting LVDS or FPD-Link II video data lanes from ESD in automotive center-stack displays exposed to dry-climate cabin discharges. IC Role / Device Role / Timing Role: High-surge-capable (3 A, 8/20 μs) clamp on differential video pairs, mounted at display connector interface. Use Value: Survives repeated ±30 kV contact discharges without parameter shift, verified over 1000 cycles per AEC-Q200 stress profile. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR (Texas Instruments) | Unidirectional; 5.5 V VRWM; 15 pF @ 0 V; ±8 kV IEC 61000-4-2 | Limited to unidirectional signal paths (e.g., power rails); higher capacitance reduces bandwidth in high-speed data lines | Select when protecting 3.3 V supply rails or low-frequency GPIO where asymmetry is unnecessary |
| ESD5Z5.0T1G (ON Semiconductor) | Unidirectional; 5.0 V VRWM; 30 pF @ 0 V; ±30 kV IEC 61000-4-2; SOD-523 package (1.2 × 0.8 mm) | Larger footprint and higher capacitance degrade signal integrity above 100 Mbps; lacks BiAs low-VF clamping | Choose only for cost-sensitive, non-high-speed applications where board space allows larger SOD-523 and bandwidth is not critical |
Compared with TPD2E001DRYR and ESD5Z5.0T1G, the VESD05A1B-HD1-GS08 uniquely delivers bidirectional asymmetrical clamping in an ultra-low-profile package with 12 pF capacitance - making it the only option among the three suitable for USB 2.0 and HDMI DDC without compromising signal fidelity or board real estate.

FAQ
What is the clamping behavior of the VESD05A1B-HD1-GS08 during positive and negative ESD events?
The VESD05A1B-HD1-GS08 exhibits bidirectional asymmetrical (BiAs) clamping: negative transients trigger forward conduction with VF ≤ 1.2 V at 0.2 A, clamping close to ground; positive transients exceed VBR (6–7.5 V) and clamp at VC ≤ 9.5 V at 1 A. This asymmetry preserves signal DC levels and minimizes distortion on bidirectional buses like USB D+/D–.
Does the VESD05A1B-HD1-GS08 meet IEC 61000-4-2 Level 4 requirements?
Yes - the VESD05A1B-HD1-GS08 exceeds IEC 61000-4-2 Level 4, delivering ±30 kV contact discharge and ±30 kV air discharge immunity. This performance is validated per the official Vishay datasheet (Doc. #81796, Rev. 2.3), making it suitable for industrial and consumer equipment requiring highest-tier ESD robustness.
Can the VESD05A1B-HD1-GS08 be used on a 3.3 V data line?
Yes - the VESD05A1B-HD1-GS08 has a 5 V reverse standoff voltage (VRWM), providing sufficient margin above 3.3 V nominal operation. Its leakage current remains ≤0.1 μA at 5 V, ensuring negligible loading on 3.3 V logic or analog signals, and its 12 pF capacitance avoids timing skew in 3.3 V high-speed interfaces.
What is the maximum operating temperature range for the VESD05A1B-HD1-GS08?
The VESD05A1B-HD1-GS08 supports a junction temperature range of –40 °C to +125 °C, validated per absolute maximum ratings in the Vishay datasheet. This enables deployment in automotive infotainment modules, industrial HMI panels, and outdoor portable electronics without derating.
Is the VESD05A1B-HD1-GS08 compatible with lead-free reflow processes?
Yes - the VESD05A1B-HD1-GS08 is qualified for lead-free reflow with a peak temperature of up to 260 °C (per J-STD-020), MSL Level 1 rating, and NiPdAu (e4) terminations. No pre-bake is required, and standard AOI suffices for solder joint inspection - no X-ray needed.
