Product details
Overview
VESD01C1-02V-G3-08 from Vishay Semiconductors is a unidirectional ESD-protection diode in SOD-523 package, rated for 1 V reverse standoff voltage, ±30 kV IEC 61000-4-2 contact/air discharge immunity, and 11 A peak pulse current (8/20 μs), designed for high-density USB, HDMI, and audio line protection in portable electronics.
For engineers reviewing the VESD01C1-02V-G3-08 datasheet, VESD01C1-02V-G3-08 pinout, VESD01C1-02V-G3-08 application, or VESD01C1-02V-G3-08 equivalent, key selection criteria include clamping voltage (≤6.4 V at 11 A), low dynamic resistance (0.13 Ω), capacitance (153–230 pF), and AEC-Q101 qualification readiness - critical for space-constrained, high-reliability signal-line ESD hardening.
Technical Context
This device operates as a single-line, cathode-grounded transient voltage suppressor with avalanche breakdown at 1.5–2.8 V (IR = 1–20 mA). Its low-profile SOD-523 package enables placement directly at I/O connectors, minimizing trace inductance to preserve clamping response under fast-rising ESD events (0.7–1 ns rise time per IEC 61000-4-2).
It delivers 70 W peak pulse power (8/20 μs) with forward clamping of ≤3.2 V at 11 A and reverse clamping of ≤6.4 V - enabling robust protection of 1.2 V–1.8 V logic interfaces without signal distortion. The Sn (e3) termination supports AOI inspection and standard reflow profiles up to 260 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 1 V - defines maximum continuous DC operating voltage before leakage rises; matches 1.0 V I/O rails (e.g., certain sensor interfaces) |
| Reverse Clamping Voltage | ≤6.4 V at 11 A (8/20 μs) - limits transient voltage seen by protected IC input, staying below typical 6.5 V absolute max ratings |
| ESD Immunity | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - exceeds Level 4 industrial requirement, suitable for handheld device touch/sensor ports |
| Capacitance | 153–230 pF at 0 V / 1 MHz - low enough for USB 2.0 (480 Mbps) and analog audio lines; higher than VESD05C1-02V but necessary for 1 V rail compatibility |
| Dynamic Resistance | 0.13 Ω (TLP, 100 ns) - ensures rapid voltage collapse during sub-nanosecond ESD transients, reducing energy delivered to downstream circuitry |
| Package | SOD-523 - 1.3 × 0.85 × 0.7 mm footprint with <0.7 mm height; compatible with 0201 land pattern and automated pick-and-place |
| Operating Temperature | −55 °C to +150 °C - supports automotive under-hood and industrial edge-node deployments where ambient extremes occur |
Pinout & Package
SOD-523 package: 2-terminal surface-mount device with cathode marked by bar; total weight 1.32 mg; UL 94 V-0 molding compound; MSL level 1 (unlimited floor life at ≤30 °C / 60% RH).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Input/line side | Connected to protected signal line (e.g., USB D+, HDMI TMDS); conducts during positive ESD strike to ground |
| Cathode (Pin 2) | Ground reference | Connected to system ground plane; establishes unidirectional conduction path; must be low-inductance for effective clamping |
Key Features
| Feature | Design Value |
|---|---|
| Compact SOD-523 footprint | Enables placement within 2 mm of I/O connector, minimizing PCB trace inductance and preserving clamping speed |
| Low profile (<0.7 mm height) | Permits use in ultra-thin consumer devices (e.g., earbuds, wearables) where Z-height is constrained |
| 1-line unidirectional topology | Optimized for ground-referenced signal lines (e.g., UART, I²C, analog sensors), avoiding bidirectional leakage trade-offs |
| AEC-Q101 qualification path | Supports automotive infotainment and ADAS peripheral protection where reliability validation is mandatory |
| Sn (e3) lead plating | Enables automated optical inspection (AOI) of solder joints and compatibility with Pb-free reflow profiles (peak 260 °C) |
Applications
| USB 2.0 Data Lines | HDMI Hot-Plug Detect (HPD) |
|---|---|
Use Scenario: Protecting D+ and D− lines in mobile phone USB-C receptacles against repeated ESD events during cable insertion/removal. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed between connector and USB PHY, shunting transients to chassis ground. Use Value: Clamps to ≤6.4 V within nanoseconds, preventing latch-up or gate oxide damage in 1.2 V PHY inputs while adding only 192 pF loading. |
Use Scenario: Safeguarding HDMI HPD pin (open-drain, 5 V tolerant) in set-top boxes exposed to user-hand ESD during HDMI cable mating. IC Role / Device Role / Timing Role: Standoff-rated ESD suppressor on HPD line, blocking 5 V DC while diverting ±30 kV strikes to ground. Use Value: Maintains 1 V reverse standoff to avoid leakage on low-current HPD pull-up, yet clamps fast-rising ESD to safe levels before controller reset occurs. |
| Industrial Sensor Interface | Audio Jack ESD Protection |
Use Scenario: Shielding 1.8 V analog output lines from pressure/temperature sensors mounted on factory-floor equipment subject to operator ESD. IC Role / Device Role / Timing Role: Low-capacitance transient suppressor on sensor output trace, positioned immediately after connector entry point. Use Value: 192 pF capacitance avoids signal integrity degradation at 10 kHz bandwidth; 11 A pulse rating handles multiple ESD events without degradation. |
Use Scenario: Protecting 3.5 mm audio jack MIC and GND lines in Bluetooth headsets from human-body-model discharges during daily handling. IC Role / Device Role / Timing Role: Cathode-grounded ESD diode on each audio path, leveraging low dynamic resistance (0.13 Ω) to minimize clamping delay. Use Value: Sub-6.4 V clamping prevents pop-noise coupling into amplifier input stages; SOD-523 size allows dual-channel layout in tight jack vicinity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD-protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMF05CTHE3_Q | Higher VRWM (5 V), lower capacitance (55 pF typ.), SOD-123 package (larger footprint, 1.6 mm height) | Better suited for 3.3 V/5 V digital lines where lower capacitance is critical; not ideal for 1 V rails due to 5 V standoff | Select when protecting 3.3 V USB or Ethernet lines requiring <60 pF loading and higher working voltage margin |
| TPD1E10B06DPYR | Lower VRWM (0.6 V), lower capacitance (12 pF typ.), same SOD-523 package, but rated only to ±12 kV contact | Optimized for ultra-low-voltage interfaces (e.g., 0.8 V DDR I/O), but insufficient for industrial ±30 kV requirements | Choose for battery-powered IoT sensor nodes with sub-1 V supplies where minimal capacitance dominates over ESD level |
Compared with SMF05CTHE3_Q and TPD1E10B06DPYR, VESD01C1-02V-G3-08 uniquely balances 1 V standoff compatibility, ±30 kV immunity, and SOD-523 miniaturization - making it the only option among the three qualified for both 1 V logic protection and harsh-environment ESD compliance.

FAQ
What is the maximum continuous reverse voltage the VESD01C1-02V-G3-08 can withstand?
The VESD01C1-02V-G3-08 has a reverse standoff voltage (VRWM) of 1 V, meaning it blocks up to 1 V DC continuously without significant leakage. At 1 V reverse bias, its typical leakage current is 20 μA (max 100 μA), making it suitable for 1.0 V I/O domains such as certain low-power sensor interfaces or legacy logic families.
Does the VESD01C1-02V-G3-08 meet automotive qualification standards?
The VESD01C1-02V-G3-08 is part of a family offering AEC-Q101-qualified variants (e.g., VESD01C1-02VHG3-08). While the -G3-08 suffix denotes RoHS-compliant, green, 8 mm tape packaging, the base die is qualified per AEC-Q101 when ordered with the 'H' environmental code - confirming suitability for automotive infotainment and body electronics.
How does the clamping performance of VESD01C1-02V-G3-08 compare under IEC 61000-4-5 surge versus IEC 61000-4-2 ESD?
The VESD01C1-02V-G3-08 clamps to ≤6.4 V at 11 A (8/20 μs waveform per IEC 61000-4-5) and achieves ±30 kV immunity per IEC 61000-4-2. Its low dynamic resistance (0.13 Ω) ensures consistent clamping across both test conditions, unlike higher-VRWM variants that trade clamping voltage for standoff range.
Can VESD01C1-02V-G3-08 be used in bidirectional signal paths like I²C?
No - VESD01C1-02V-G3-08 is unidirectional and cathode-grounded. For bidirectional lines such as I²C, a symmetric (bidirectional) ESD suppressor like VESD05C1-02V or dedicated dual-diode arrays are required. Using VESD01C1-02V-G3-08 on I²C would block the high-side pull-up path and disrupt communication.
What is the moisture sensitivity level (MSL) and reflow profile for VESD01C1-02V-G3-08?
The VESD01C1-02V-G3-08 has MSL level 1 per J-STD-020, meaning unlimited floor life at ≤30 °C / 60% RH. Its Sn (e3) terminations support standard Pb-free reflow with peak temperature up to 260 °C, compatible with IPC/JEDEC J-STD-020D.2 guidelines.
