Product details
Overview
VESD08C1-HD1HG3-08 from Vishay Semiconductors is a unidirectional ESD-protection diode in DFN1006-2A package, designed for single-line I/O protection in space-constrained consumer and automotive electronics. It features 8 V reverse stand-off voltage, 30 kV IEC 61000-4-2 contact/air discharge immunity, and 13.7 V typical reverse clamping voltage at 6.6 A peak pulse current.
For engineers reviewing the VESD08C1-HD1HG3-08 datasheet, VESD08C1-HD1HG3-08 pinout, VESD08C1-HD1HG3-08 application, or VESD08C1-HD1HG3-08 equivalent, this device serves as a low-capacitance (47 pF typ.), AEC-Q101-qualified transient suppressor for USB 2.0, HDMI, and automotive sensor interfaces where board area and signal integrity are critical.
Technical Context
This device implements a single-channel, unidirectional TVS structure optimized for fast response to ESD transients per IEC 61000-4-2. Its DFN1006-2A footprint enables placement directly at connector entry points with minimal trace inductance.
It operates within -55 °C to +150 °C junction temperature range and delivers 100 W peak pulse power (8/20 μs) while maintaining low dynamic resistance (0.23 Ω typ.) and sub-0.5 mm profile - essential for modern high-density PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 8 V - maximum continuous operating voltage before conduction; sets safe margin below system rail (e.g., 5 V or 3.3 V I/O). |
| Reverse Clamping Voltage | 13.7 V typ. at 6.6 A - limits transient voltage seen by downstream IC during IEC 61000-4-5 surge events. |
| Capacitance | 47 pF typ. at 0 V - low enough for <12 Mbps USB 2.0 and HDMI DDC lines without signal degradation. |
| ESD Immunity | ±30 kV contact / ±30 kV air per IEC 61000-4-2 - exceeds Level 4 industrial and automotive requirements. |
| Package | DFN1006-2A (1.0 × 0.6 × 0.4 mm) - ultra-compact, solderable via standard reflow, MSL level 1. |
| Junction Temp Range | -55 °C to +150 °C - supports under-hood automotive and industrial environments without derating. |
Pinout & Package
DFN1006-2A package: 2-terminal surface-mount device with cathode marked by bar on top surface. Dimensions: 1.0 mm × 0.6 mm × 0.4 mm max height. Terminal pitch: 0.55 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode) | Input line connection | Connected to protected signal line (e.g., USB D+); conducts during negative ESD events. |
| Pin 2 (Cathode) | Ground reference | Connected to system ground plane; provides low-inductance return path for transient current. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional ESD protection | Enables precise clamping only on negative transients - ideal for DC-biased data lines like USB or CAN. |
| AEC-Q101 qualified | Validated for automotive applications including infotainment, ADAS sensors, and body control modules. |
| Low 0.23 Ω dynamic resistance | Minimizes voltage overshoot during fast ESD pulses, improving protection margin for sensitive receivers. |
| Sn (e3) lead plating | Enables AOI-compatible solder joint inspection and RoHS-compliant reflow processing. |
| MSL level 1 rating | Allows unlimited floor life and standard reflow without baking - reduces manufacturing overhead. |
Applications
| USB 2.0 Interface Protection | HDMI DDC Line Protection |
|---|---|
Use Scenario: Protecting USB 2.0 D+ and D- lines against ESD events during cable insertion or handling in portable devices. IC Role / Device Role / Timing Role: Unidirectional transient voltage suppressor placed at USB connector, clamping negative surges to ground. Use Value: 47 pF capacitance avoids signal rise-time degradation; 13.7 V clamping ensures connected PHY remains within absolute maximum ratings. |
Use Scenario: Safeguarding HDMI Display Data Channel (DDC) lines (SCL/SDA) from user-induced ESD in TVs and monitors. IC Role / Device Role / Timing Role: Single-line ESD clamp on 5 V-tolerant I²C bus, preserving open-drain logic behavior. Use Value: 8 V VRWM matches DDC pull-up voltage; ±30 kV ESD rating exceeds IEC 61000-4-2 Level 4 requirement. |
| Automotive Sensor Signal Lines | Industrial RS-485 Transceiver I/O |
Use Scenario: Protecting analog/digital sensor outputs (e.g., temperature, pressure) in automotive ECUs exposed to harsh ESD environments. IC Role / Device Role / Timing Role: Point-of-entry ESD suppressor on sensor interface lines routed through vehicle harnesses. Use Value: -55 °C to +150 °C operation supports engine bay mounting; AEC-Q101 qualification confirms reliability under thermal cycling. |
Use Scenario: Shielding RS-485 transceiver A/B pins from ESD in factory automation equipment with frequent cable disconnection. IC Role / Device Role / Timing Role: Low-capacitance unidirectional clamp on half-duplex differential bus lines. Use Value: 13.7 V clamping prevents latch-up in transceivers; DFN1006-2A size allows placement adjacent to connector without trace stubs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD-protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A | DO-214AC package (4.5 × 2.7 mm), 100 W Ppp, 12.5 V Vc @ 7.5 A - larger footprint, higher clamping. | Used in non-space-constrained industrial power rails; not suitable for high-speed data lines due to ~200 pF capacitance. | Select when board area is available and lower cost per watt is prioritized over signal integrity. |
| TPD2E001DRYR | 2-channel bidirectional array in DFN1006-3 (1.0 × 0.6 mm), 12 pF capacitance, 8 V Vrwm - lower capacitance but bidirectional clamping. | Preferred for symmetric signal pairs (e.g., USB D+/D-) requiring dual-line protection in same footprint. | Choose when protecting differential pairs or needing lower capacitance than VESD08C1-HD1HG3-08 offers. |
Compared with SMAJ8.0A and TPD2E001DRYR, VESD08C1-HD1HG3-08 delivers optimal balance of compact size, unidirectional precision, and 47 pF capacitance for single-line high-speed interfaces - making it preferable for USB 2.0, HDMI DDC, and automotive sensor nodes where layout density and signal fidelity are critical.

FAQ
What is the maximum operating voltage for VESD08C1-HD1HG3-08?
The VESD08C1-HD1HG3-08 has a reverse stand-off voltage (VRWM) of 8 V, meaning it can continuously block up to 8 V in normal operation without conducting. This value is confirmed in the Electrical Characteristics table for VESD08C1-HD1 in the Vishay datasheet (Document No. 86185, Rev. 1.2), and defines the highest DC or peak AC voltage the device tolerates before entering breakdown.
Is VESD08C1-HD1HG3-08 AEC-Q101 qualified?
Yes, VESD08C1-HD1HG3-08 is AEC-Q101 qualified. The datasheet states "AEC-Q101 qualified available" for the VESDxxC1-HD1 series, and the ordering code suffix "H" in the part number (as shown in the Ordering Information table) explicitly denotes AEC-Q101 qualification for VESD08C1-HD1HG3-08.
What is the clamping voltage of VESD08C1-HD1HG3-08 under ESD stress?
The VESD08C1-HD1HG3-08 exhibits a typical reverse clamping voltage (VC) of 13.7 V at 6.6 A peak pulse current (8/20 μs waveform), per the Electrical Characteristics table. This value represents the maximum voltage imposed on the protected line during an IEC 61000-4-5 surge event, ensuring downstream ICs remain within safe operating limits.
Does VESD08C1-HD1HG3-08 support automated optical inspection (AOI)?
Yes, VESD08C1-HD1HG3-08 supports AOI due to its Sn (e3) lead plating, which provides consistent reflectivity and contrast for vision-based solder-joint inspection. The datasheet explicitly notes "soldering can be checked by standard vision inspection" and "AOI = Automated Optical Inspection" under the Features section.
What is the moisture sensitivity level (MSL) for VESD08C1-HD1HG3-08?
VESD08C1-HD1HG3-08 has a moisture sensitivity level (MSL) of level 1 per J-STD-020, as documented in the Package Data table. This means the device may be stored indefinitely at ambient conditions (<30 °C / 60% RH) and subjected to standard reflow profiles (peak ≤260 °C) without baking or special handling.
