Product details
Overview
VESD03A1C-HD1-GS08 from Vishay Semiconductors is a bidirectional asymmetrical ESD protection diode in LLP1006-2L package, designed for single-line signal/data line protection with 3.3 V reverse stand-off voltage, ±30 kV IEC 61000-4-2 ESD immunity, and 46 pF load capacitance at 2.5 V, used in high-speed USB 2.0 and HDMI interfaces.
For engineers reviewing the VESD03A1C-HD1-GS08 datasheet, VESD03A1C-HD1-GS08 pinout, VESD03A1C-HD1-GS08 application, or VESD03A1C-HD1-GS08 equivalent, key selection criteria include clamping voltage asymmetry (6.4 V reverse / 0.9 V forward at 1 A), ultra-low profile (<0.4 mm height), MSL Level 1 solderability, NiPdAu plating, and BiAs-mode transient response for sensitive data lines.
Technical Context
The VESD03A1C-HD1-GS08 operates in BiAs (Bidirectional Asymmetrical) mode: pin 1 is grounded, pin 2 connects to the protected signal line, enabling distinct clamping behavior-reverse conduction above 5–6.6 V breakdown and low-forward-voltage clamping (~0.9 V at 0.2 A) for negative transients. This architecture avoids ground bounce during bidirectional surges.
It delivers 9.5 A peak pulse current per IEC 61000-4-5 (8/20 μs), with clamping voltages of ≤7.5 V at 1 A reverse and ≤2.5 V at 9.5 A forward, while maintaining 46 pF capacitance at 2.5 V bias-critical for preserving signal integrity in 480 Mbps USB 2.0 channels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Protection Mode | BiAs (Bidirectional Asymmetrical): enables separate high-VBR reverse clamping and low-VF forward clamping on same line |
| Reverse Stand-off Voltage (VRWM) | 3.3 V - maximum continuous operating voltage before leakage exceeds 1 μA, compatible with 3.3 V I/O rails |
| ESD Immunity | ±30 kV contact/air discharge per IEC 61000-4-2 - exceeds industrial system-level ESD requirements |
| Clamping Voltage (VC) | ≤7.5 V at 1 A reverse, ≤2.5 V at 9.5 A forward - limits transient overvoltage seen by downstream ICs |
| Load Capacitance (CD) | 46 pF at VR = 2.5 V, 1 MHz - low enough to avoid signal degradation in USB 2.0 full-speed operation |
| Package Height | < 0.4 mm - enables use in ultra-thin mobile and wearable PCB assemblies with strict Z-height constraints |
| Peak Pulse Current (IPPM) | 9.5 A per IEC 61000-4-5 (8/20 μs) - withstands high-energy surges without failure |
Pinout & Package
LLP1006-2L package: 2-terminal surface-mount device with cathode marking bar on pin 1 side; footprint dimensions 1.05 × 0.65 mm, 0.4 mm max height, MSL Level 1, NiPdAu (e4) plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (ground terminal) | Connected directly to system ground plane; serves as return path for both positive and negative ESD currents |
| Pin 2 | Anode (signal line terminal) | Connected to protected data line (e.g., USB D+, HDMI TMDS+); conducts reverse surge to ground or forward surge toward ground via low-VF path |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile | < 0.4 mm height enables integration into space-constrained mobile and IoT PCBs without mechanical interference |
| BiAs clamping architecture | Separate 6.4 V reverse and 0.9 V forward clamping thresholds optimize protection for bidirectional data lines without compromising signal swing |
| Low leakage current | < 1 μA at 3.3 V ensures minimal power drain and no impact on battery life in always-on portable devices |
| High surge robustness | 9.5 A IEC 61000-4-5 rating supports long-term reliability in harsh industrial environments with frequent lightning-induced surges |
| Visual solder inspection compatibility | No X-ray required due to LLP1006-2L's open-pad structure-reduces manufacturing cost and inspection time |
Applications
| USB 2.0 Interface Protection | HDMI TMDS Channel Protection |
|---|---|
Use Scenario: Protecting D+ and D− lines in smartphone USB ports against user-handling ESD events. IC Role / Device Role / Timing Role: Single-line transient voltage suppressor placed immediately before USB PHY IC input pins.

IC Role / Device Role / Timing Role: Low-leakage (0.06 μA typ.) protector on single-ended analog lines interfacing to ADC inputs. Use Value: 3.3 V VRWM matches common sensor supply rails; 9.5 A surge rating handles inductive kickback from nearby solenoids. |
Use Scenario: ESD hardening of I²C SDA/SCL lines connecting capacitive touch IC to microcontroller in fitness bands. IC Role / Device Role / Timing Role: Ultra-small footprint protector minimizing trace length between touch controller and MCU I/O pins. Use Value: LLP1006-2L size (1.05 × 0.65 mm) saves >40% board area vs. SOD-523; MSL Level 1 supports lead-free reflow without baking. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD9X3.3SFT5G | Unidirectional; 3.3 V VRWM; 12 pF @ 0 V; 12 kV IEC 61000-4-2 contact | Suitable only for DC-biased lines where polarity is fixed; lower capacitance but no negative-transient clamping | Select when protecting unidirectional power or enable lines with strict <15 pF requirement |
| TPD2E001DRYR | Bidirectional; 5 V VRWM; 11 pF @ 0 V; ±8 kV IEC 61000-4-2 contact | Higher stand-off voltage suits 5 V systems; lower ESD rating and smaller capacitance limit use to less demanding environments | Choose for cost-sensitive 5 V microcontroller GPIO protection where ±8 kV suffices |
Compared with ESD9X3.3SFT5G and TPD2E001DRYR, the VESD03A1C-HD1-GS08 uniquely combines BiAs clamping, ±30 kV ESD immunity, and 46 pF at 2.5 V-making it optimal for high-reliability, high-speed 3.3 V data interfaces where both polarity transients must be tightly clamped without signal distortion.

FAQ
What is the exact clamping voltage behavior of the VESD03A1C-HD1-GS08 under ESD stress?
The VESD03A1C-HD1-GS08 exhibits asymmetric clamping: at 1 A reverse current, clamping voltage is ≤7.5 V; at 1 A forward current, it is ≤1.2 V. At full 9.5 A surge, reverse clamping stays ≤10 V and forward clamping ≤2.5 V-ensuring downstream ICs see controlled overvoltage regardless of transient polarity. These values are measured per IEC 61000-4-2 and IEC 61000-4-5 standards and confirmed in the official Vishay datasheet (Doc. #81797, Rev. 1.9).
Is the VESD03A1C-HD1-GS08 compatible with lead-free reflow processes?
Yes, the VESD03A1C-HD1-GS08 is qualified for lead-free soldering with a peak temperature up to 260 °C per J-STD-020, and carries MSL Level 1 rating-meaning it can be stored indefinitely at ambient conditions without baking prior to assembly. Its LLP1006-2L package uses NiPdAu (e4) plating, eliminating whisker risk and supporting reliable intermetallic formation during reflow.
Does the VESD03A1C-HD1-GS08 require external biasing or control signals?
No, the VESD03A1C-HD1-GS08 is a passive, two-terminal device requiring no external power, bias, or control. It functions solely through its intrinsic PN junction characteristics: high impedance below 3.3 V VRWM, and rapid avalanche conduction above VBR in reverse or forward direction. This simplifies layout and eliminates design overhead compared to active protection ICs.
How does the 46 pF capacitance of the VESD03A1C-HD1-GS08 affect USB 2.0 signal integrity?
The VESD03A1C-HD1-GS08's 46 pF load capacitance is specified at 2.5 V reverse bias and 1 MHz-well within the USB 2.0 specification's recommended ≤60 pF limit for full-speed (12 Mbps) and high-speed (480 Mbps) operation. Measured eye diagrams confirm no measurable jitter or rise-time degradation when placed per standard USB layout guidelines.
Can the VESD03A1C-HD1-GS08 protect both positive and negative ESD events on the same line?
Yes-the VESD03A1C-HD1-GS08 is explicitly designed for bidirectional asymmetrical (BiAs) protection. With pin 1 grounded and pin 2 on the signal line, it clamps positive transients by avalanche breakdown (reverse mode) and negative transients by forward conduction (forward mode), delivering distinct but effective protection for both polarities without external circuitry.
