Product details
Overview
VESD05C1-02VHG3-08 from Vishay Semiconductors is a unidirectional ESD protection diode in SOD-523 package, designed for 5 V signal-line protection with 10.3 V typical reverse clamping voltage at 8.7 A peak pulse current, < 0.1 μA reverse leakage at 5 V, and 67 pF capacitance at 0 V - deployed in USB 2.0 data lines, HDMI hot-plug detection, and industrial I/O interfaces.
For engineers reviewing the VESD05C1-02VHG3-08 datasheet, VESD05C1-02VHG3-08 pinout, VESD05C1-02VHG3-08 application, or VESD05C1-02VHG3-08 equivalent, key selection criteria include clamping voltage vs. protected IC's absolute maximum rating, capacitance impact on signal integrity, SOD-523 footprint compatibility, and AEC-Q101 qualification status (not applicable to this variant).
Technical Context
This device implements a single-line, unidirectional TVS structure optimized for low-capacitance transient suppression. Its 5 V reverse standoff voltage (VRWM) aligns with standard 5 V logic rails, while its 7.26 V typical breakdown voltage (VBR) ensures robust triggering margin above operating voltage.
The SOD-523 package enables placement directly at connector entry points with minimal trace inductance. Dynamic resistance of 0.2 Ω (TLP, 100 ns) supports fast energy dissipation during ESD events per IEC 61000-4-2 (±30 kV contact/air discharge).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - maximum continuous DC voltage the line can sustain without conduction; matches standard 5 V I/O rails. |
| Reverse Clamping Voltage | 10.3 V (typ.) at 8.7 A - peak voltage seen by protected IC during IEC 61000-4-5 8/20 μs surge; must stay below IC's absolute max rating. |
| Capacitance | 67 pF at 0 V, 1 MHz - low enough for USB 2.0 (480 Mbps) and HDMI DDC lines without signal degradation. |
| ESD Immunity | ±30 kV contact / ±30 kV air per IEC 61000-4-2 - exceeds Level 4 immunity requirements for industrial and consumer end-equipment. |
| Leakage Current | 0.01 μA (typ.) at 5 V - negligible power loss and no measurable impact on high-impedance sensor or analog inputs. |
| Package | SOD-523 - 1.3 × 0.85 × 0.7 mm footprint; compatible with automated optical inspection (AOI) and reflow soldering up to 260 °C peak. |
Pinout & Package
SOD-523 package: 2-terminal surface-mount device with cathode marked by bar; dimensions 1.3 mm × 0.85 mm × 0.7 mm (L × W × H); MSL level 1; lead finish Sn (e3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Signal input / protected line connection | Connected to the vulnerable I/O trace; conducts transient current to cathode during overvoltage event. |
| Cathode (Pin 2) | Ground reference / return path | Must be tied to low-inductance system ground; forms clamping path with anode to limit voltage excursion. |
Key Features
| Feature | Design Value |
|---|---|
| Low Capacitance | 67 pF enables use on high-speed 5 V interfaces (e.g., USB 2.0, UART, I²C) without signal rise-time degradation. |
| High ESD Robustness | ±30 kV contact/air per IEC 61000-4-2 ensures reliable operation in handling-prone environments like factory floors or field service. |
| Tight Clamping Performance | 10.3 V typical VC at 8.7 A provides 1.7 V margin below common 12 V absolute max ratings of 5 V logic ICs. |
| SOD-523 Footprint | Compact 1.3 × 0.85 mm outline allows placement within 2 mm of connectors - minimizing PCB trace inductance and improving protection efficacy. |
| Lead (Pb)-Free Termination | Sn (e3) plating supports RoHS compliance and standard vision-based AOI for post-solder inspection. |
Applications
| USB 2.0 Data Lines | HDMI Hot-Plug Detection |
|---|---|
Use Scenario: Protecting D+ and D− lines against ESD during cable insertion/removal in portable docking stations. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed between connector and USB transceiver IC. Use Value: 67 pF capacitance avoids signal integrity issues at 480 Mbps; 10.3 V clamping prevents damage to transceiver's 12 V abs-max I/O pins. |
Use Scenario: Safeguarding the HDMI HPD (Hot-Plug Detect) line from user-induced ESD in home theater receivers. IC Role / Device Role / Timing Role: Standalone ESD suppressor on 5 V open-drain HPD signal routed to microcontroller GPIO. Use Value: 0.01 μA leakage preserves pull-up functionality; ±30 kV rating exceeds IEC 61000-4-2 Level 4 required for CE-marked AV equipment. |
| Industrial RS-485 Transceivers | Automotive Body Control Module I/O |
Use Scenario: Adding secondary ESD protection on RS-485 A/B differential lines in factory automation gateways. IC Role / Device Role / Timing Role: Discrete TVS pair (one per line) mounted adjacent to connector, upstream of isolated transceiver. Use Value: Low dynamic resistance (0.2 Ω) ensures rapid clamping response; SOD-523 size allows dual placement in tight 12 mm² space. |
Use Scenario: Protecting LIN bus or sensor input lines in non-AEC-Q101 body control modules where cost-sensitive design prevails. IC Role / Device Role / Timing Role: Single-line ESD clamp on 5 V analog sensor supply or digital wake-up line. Use Value: 5 V VRWM matches MCU I/O rail; 10.3 V VC stays safely below 16 V automotive-grade IC thresholds. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z5.0T1G (ON Semiconductor) | Same SOD-523 package; 5.0 V VRWM; 12.5 V VC (typ. at 5 A); 90 pF capacitance. | Higher clamping voltage and capacitance reduce suitability for USB 2.0 but acceptable for slower UART or GPIO lines. | Select when higher surge current margin (12 A IPPM) is prioritized over signal integrity. |
| TPD2E001DRYR (Texas Instruments) | 2-channel array in SOT-553; 5.5 V VRWM; 12 V VC (typ. at 4 A); 12 pF per channel. | Lower capacitance benefits high-speed interfaces, but dual-channel layout requires different routing and lacks standalone flexibility. | Choose for space-constrained multi-line protection where board area savings outweigh discrete placement control. |
Compared with VESD05C1-02VHG3-08, ES5Z5.0T1G trades lower clamping performance for higher surge tolerance, while TPD2E001DRYR offers lower capacitance in a multi-channel format - making VESD05C1-02VHG3-08 optimal for single-line, cost-sensitive, 5 V signal protection where 67 pF and 10.3 V VC are critical.

FAQ
What is the maximum operating temperature range for VESD05C1-02VHG3-08?
VESD05C1-02VHG3-08 operates from -55 °C to +150 °C junction temperature, supporting deployment in under-hood automotive modules, industrial PLCs, and outdoor-rated networking gear. This wide range is enabled by Vishay's silicon process and SOD-523 mold compound rated UL 94 V-0.
Does VESD05C1-02VHG3-08 meet AEC-Q101 qualification?
No, VESD05C1-02VHG3-08 is not AEC-Q101 qualified. The AEC-Q101 variant is designated VESD05C1-02VH, without the "G3-08" suffix. VESD05C1-02VHG3-08 carries green RoHS-compliant packaging (G), Sn plating (3), and 8 k/reel tape-and-reel (08), but lacks automotive stress testing certification.
How does the 67 pF capacitance of VESD05C1-02VHG3-08 affect USB 2.0 signal integrity?
The 67 pF capacitance of VESD05C1-02VHG3-08 introduces < 0.5 dB insertion loss at 240 MHz (Nyquist frequency of 480 Mbps USB 2.0), preserving eye diagram opening and jitter margins. Layout best practices - short traces, ground pour clearance, and placement within 3 mm of the connector - maintain full compliance.
What is the meaning of the "-08" suffix in VESD05C1-02VHG3-08?
The "-08" suffix in VESD05C1-02VHG3-08 indicates 8,000 units per 7-inch reel in 8 mm carrier tape - the standard packaging configuration for high-volume SMT assembly. It does not denote revision, temperature grade, or reliability level.
Can VESD05C1-02VHG3-08 be used on bidirectional signal lines like I²C?
Yes, VESD05C1-02VHG3-08 can protect bidirectional 5 V lines such as I²C, provided the circuit uses pull-up resistors to 5 V and the protected IC tolerates up to 10.3 V clamping during ESD events. Its unidirectional architecture requires correct orientation: anode to signal line, cathode to ground.
