Product details
Overview
VESD26C1-02VHG3-08 from Vishay Semiconductors is a unidirectional ESD-protection diode in SOD-523 package, rated for 26 V reverse standoff voltage, 2.1 A peak pulse current (IEC 61000-4-5), and 20 kV ESD immunity (IEC 61000-4-2 contact/air). It delivers 43–48 V reverse clamping at full surge and < 0.01 μA leakage at 26 V, targeting high-speed data line protection in automotive infotainment and industrial I/O interfaces.
For engineers reviewing the VESD26C1-02VHG3-08 datasheet, VESD26C1-02VHG3-08 pinout, VESD26C1-02VHG3-08 application, or VESD26C1-02VHG3-08 equivalent, key selection criteria include its 17.5 pF capacitance at 0 V, 1.9 Ω dynamic resistance, SOD-523 footprint compatibility, and AEC-Q101 qualification status - all critical for USB 2.0, CAN FD, and sensor interface transient suppression.
Technical Context
This device implements a single-line, unidirectional TVS structure optimized for low-capacitance signal integrity preservation. Its clamping behavior is defined by a 27.6–30.6 V breakdown threshold at 1 mA and a tightly controlled 43–48 V reverse clamping window under 2.1 A 8/20 μs transients.
The SOD-523 package enables integration into space-constrained PCB layouts with < 0.7 mm height and MSL level 1 soldering compatibility. Its Sn (e3) termination supports AOI inspection and lead-free reflow up to 260 °C peak temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 26 V - maximum continuous operating voltage before conduction begins; sets upper limit for protected line DC bias. |
| Reverse Clamping Voltage | 43–48 V at 2.1 A, 8/20 μs - peak voltage seen by downstream circuit during worst-case surge; defines protection margin. |
| Capacitance | 17.5 pF at 0 V, 1 MHz - low enough for USB 2.0 (480 Mbps) and CAN FD (5 Mbps) without signal distortion. |
| ESD Immunity | ±20 kV contact / ±20 kV air (IEC 61000-4-2) - meets automotive and industrial system-level ESD test requirements. |
| Dynamic Resistance | 1.9 Ω (TLP, 100 ns) - determines clamping voltage rise slope and energy dissipation efficiency under fast transients. |
| Leakage Current | < 0.01 μA at 26 V - negligible power loss and signal loading in battery-powered or high-impedance circuits. |
| Operating Temperature | −55 °C to +150 °C - supports under-hood automotive and industrial control unit deployment. |
Pinout & Package
SOD-523 package: 2-terminal surface-mount device, 1.3 × 0.85 × 0.7 mm (L × W × H), cathode-marked anode-cathode orientation, MSL level 1, Sn (e3) plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Input side of protected line | Connected to signal source or connector; carries transient current into diode during positive ESD events. |
| Cathode (Pin 2) | Ground reference terminal | Connected to system ground plane; completes current path during ESD discharge; requires low-inductance layout. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional ESD protection | Clamps only negative transients relative to ground; preserves DC bias integrity on positive-rail signal lines. |
| AEC-Q101 qualified | Validated for automotive applications including infotainment, body control modules, and ADAS sensor interfaces. |
| Low 17.5 pF capacitance | Minimizes signal rise-time degradation and insertion loss on high-speed serial links (e.g., USB 2.0, LIN). |
| SOD-523 footprint | Enables placement adjacent to connectors or IC pins with minimal PCB area (< 1.1 mm²) and no via clearance conflicts. |
| Sn (e3) termination | Supports automated optical inspection (AOI) and RoHS-compliant reflow without lead contamination risk. |
Applications
| USB 2.0 Data Lines | CAN FD Bus Interface |
|---|---|
Use Scenario: Protecting D+ and D− lines of USB 2.0 ports against ESD events during hot-plug connection in automotive head units. IC Role / Device Role / Timing Role: Unidirectional transient voltage suppressor placed between connector and USB PHY, clamping surges before they reach the transceiver. Use Value: 17.5 pF capacitance avoids eye-diagram closure; 43–48 V clamping ensures PHY I/O remains within absolute maximum ratings during ±20 kV contact discharge. |
Use Scenario: Safeguarding CAN FD controller and transceiver pins against ESD in vehicle network gateways and ECUs. IC Role / Device Role / Timing Role: Point-of-entry protection on CANH/CANL lines, absorbing fast transients while maintaining bus differential signaling integrity. Use Value: Low dynamic resistance (1.9 Ω) limits clamping overshoot; −55 °C to +150 °C rating matches under-hood thermal cycling requirements. |
| Industrial Sensor I/O | Automotive LIN Bus Nodes |
Use Scenario: Shielding analog and digital sensor outputs (e.g., pressure, temperature) from ESD in factory automation PLC modules. IC Role / Device Role / Timing Role: Single-line protection on sensor output traces, placed immediately after connector to minimize loop inductance. Use Value: 26 V standoff accommodates 24 V industrial supply rails; < 0.01 μA leakage prevents measurement offset in high-impedance signal chains. |
Use Scenario: ESD hardening of LIN slave nodes in door modules, seat controls, and lighting systems. IC Role / Device Role / Timing Role: Bidirectional protection not required; unidirectional VESD26C1-02VHG3-08 used on LIN bus line referenced to chassis ground. Use Value: SOD-523 size allows placement directly at connector; AEC-Q101 qualification confirms reliability for 15-year automotive service life. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD-protection diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ26A-E3/57T | DO-214AC package; 300 W peak power; 400 V standoff; 100 pF capacitance | Designed for higher-energy surges (e.g., lightning-induced); unsuitable for high-speed data due to capacitance | Select when protecting 24 V power rails or low-frequency analog lines where speed is not critical. |
| TPD2E001DRYR | 2-channel, bidirectional; 0.9 pF per channel; 5 V standoff; SOT-553 package | Optimized for USB 2.0 and HDMI; lacks AEC-Q101 qualification and 26 V standoff capability | Prefer for consumer-grade high-speed interfaces requiring ultra-low capacitance; not suitable for automotive 24 V systems. |
Compared with SMAJ26A-E3/57T and TPD2E001DRYR, VESD26C1-02VHG3-08 uniquely balances 26 V standoff, 17.5 pF capacitance, AEC-Q101 qualification, and SOD-523 miniaturization - making it the only option among the three validated for automotive CAN FD and industrial 24 V sensor I/O protection.

FAQ
What is the maximum working voltage supported by VESD26C1-02VHG3-08?
VESD26C1-02VHG3-08 has a reverse standoff voltage (VRWM) of 26 V, meaning it can continuously block up to 26 V DC or peak AC signals without entering conduction. This makes it suitable for 24 V industrial buses and automotive subsystems where nominal rail voltages approach 24 V with tolerance margins.
Is VESD26C1-02VHG3-08 qualified for automotive use?
Yes, VESD26C1-02VHG3-08 is AEC-Q101 qualified, confirming its reliability for automotive applications including engine control units, body electronics, and infotainment systems. The qualification covers temperature cycling, humidity testing, and mechanical shock per AEC standards.
What is the clamping voltage of VESD26C1-02VHG3-08 under a 2.1 A transient?
VESD26C1-02VHG3-08 clamps to 43–48 V when subjected to a 2.1 A, 8/20 μs surge per IEC 61000-4-5. This value is measured across the device terminals and defines the maximum overvoltage imposed on downstream circuitry during standardized surge events.
Does VESD26C1-02VHG3-08 support high-speed data interfaces like USB 2.0?
Yes, VESD26C1-02VHG3-08's typical capacitance of 17.5 pF at 0 V and 1 MHz ensures minimal signal integrity impact on USB 2.0 (480 Mbps) and CAN FD (5 Mbps) lines. Its low dynamic resistance (1.9 Ω) further reduces clamping overshoot during fast transients.
What package type and dimensions does VESD26C1-02VHG3-08 use?
VESD26C1-02VHG3-08 uses the SOD-523 package: 1.3 mm × 0.85 mm × 0.7 mm (L × W × H), with cathode marking, Sn (e3) termination, and MSL level 1 moisture sensitivity rating. Its compact size supports dense PCB layouts near connectors or IC pins.
