Product details
Overview
VESD12-02V-G-08 from Vishay Semiconductors is a single-line ESD protection diode in SOD-523 package, designed for low-capacitance transient suppression on 12 V signal lines. It delivers ±8 kV contact / ±15 kV air ESD immunity per IEC 61000-4-2, 25 W peak pulse power (8/20 μs), and 30 pF capacitance at 0 V bias-ideal for USB 2.0, HDMI, and industrial sensor interface protection.
For engineers reviewing the VESD12-02V-G-08 datasheet, VESD12-02V-G-08 pinout, VESD12-02V-G-08 application, or VESD12-02V-G-08 equivalent, key selection criteria include reverse stand-off voltage (12 V), clamping voltage (25 V typ.), leakage current (<0.1 μA at 12 V), SOD-523 footprint compatibility, and MSL level 1 soldering profile.
Technical Context
The VESD12-02V-G-08 is a unidirectional TVS diode configured as a single-channel cathode-grounded clamp. Its 12 V reverse stand-off voltage and 14 V breakdown threshold (at 1 mA) define its operating window for 12 V rail protection without false triggering.
With 25 V typical clamping voltage under 2 A IPP, it limits transient overvoltage to safe levels for downstream ICs. Its 30 pF junction capacitance ensures minimal signal distortion on high-speed lines up to ~100 MHz, while maintaining robust ±8 kV IEC 61000-4-2 compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 12 V - maximum continuous DC or RMS signal voltage before conduction begins |
| Breakdown Voltage | 14 V (min) at 1 mA - guaranteed turn-on threshold for transient clamping |
| Clamping Voltage | 25 V (typ.) at 2 A peak pulse - limits voltage seen by protected IC during ESD event |
| Junction Capacitance | 30 pF at 0 V, 1 MHz - low enough for USB 2.0 and analog sensor interfaces |
| Leakage Current | <0.1 μA at 12 V - negligible loading on 12 V signal paths |
| ESD Immunity | ±8 kV contact / ±15 kV air per IEC 61000-4-2 - meets industrial and consumer ESD requirements |
| Peak Pulse Power | 25 W (8/20 μs) - handles single-event transients without degradation |

SOD-523 surface-mount package: 1.7 mm × 1.3 mm × 0.9 mm body, 0.35 mm lead pitch, MSL level 1, UL 94 V-0 molding compound, Sn (e3) termination.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input signal line connection | Connected to protected trace (e.g., USB D+, HDMI TMDS+) |
| Cathode | Ground reference terminal | Must be tied to low-inductance system ground for effective clamping |
Key Features

| Low 30 pF capacitance | Preserves signal integrity on high-speed interfaces up to 100 MHz bandwidth |
| Sub-0.1 μA leakage at 12 V | Prevents battery drain and DC offset errors in always-on sensor circuits |
| ±8 kV / ±15 kV IEC 61000-4-2 rating | Fully qualifies for EN 61000-6-2 and IEC 61000-6-4 industrial immunity standards |
| SOD-523 footprint | Enables compact layout with 1.3 mm × 0.9 mm PCB area and standard reflow compatibility |
Applications
| USB 2.0 Interface Protection | HDMI Signal Line Protection |
|---|---|
Use Scenario: Protecting D+ and D− lines of embedded USB 2.0 ports against ESD events during hot-plug insertion. IC Role / Device Role / Timing Role: Unidirectional transient voltage suppressor placed between connector and USB transceiver IC. Use Value: 30 pF capacitance avoids signal rise-time degradation; 25 V clamping prevents damage to PHY-level circuitry rated for ≤30 V absolute max. |
Use Scenario: Safeguarding TMDS clock and data channels in industrial display controllers exposed to handling ESD. IC Role / Device Role / Timing Role: Point-of-entry clamp on each differential pair, referenced to clean digital ground. Use Value: 12 V stand-off accommodates TMDS common-mode swing; low leakage avoids DC bias shift in AC-coupled links. |
| Industrial Sensor Signal Conditioning | Automotive Body Control Module Inputs |
Use Scenario: Protecting analog outputs of pressure or temperature sensors connected to 12 V supply rails in factory automation systems. IC Role / Device Role / Timing Role: Low-leakage shunt protector on sensor output line prior to ADC input stage. Use Value: <0.1 μA leakage eliminates measurement error in high-impedance sensor circuits; 14 V breakdown ensures no conduction during normal 12 V operation. |
Use Scenario: Shielding discrete input pins (e.g., door lock switch, mirror control) in 12 V automotive BCMs from ESD during service. IC Role / Device Role / Timing Role: Cathode-grounded TVS on each switch input, placed immediately after connector. Use Value: SOD-523 size allows dense placement near connectors; ±8 kV contact rating satisfies ISO 10605 Class III (8 kV) requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor SZ1.5SMC12A | DO-214AB package, 12 V VRWM, 33.2 V VC at 38.2 A, 1500 pF capacitance | Designed for higher-energy surges (IEC 61000-4-5), not optimized for high-speed signal lines | Select when surge energy exceeds 25 W and signal speed is ≤1 MHz |
| Littelfuse SP1003-010 | SOD-523 package, 12 V VRWM, 24 V VC at 1 A, 25 pF capacitance, ±15 kV air rating | Near-identical form factor and performance; slightly lower clamping but same ESD rating | Preferred for new designs requiring marginally lower clamping voltage and proven field reliability |

FAQ
What is the maximum continuous operating voltage for VESD12-02V-G-08?
The VESD12-02V-G-08 has a reverse stand-off voltage (VRWM) of 12 V, meaning it can continuously block up to 12 V DC or RMS signal voltage without entering conduction. This makes VESD12-02V-G-08 suitable for protecting 12 V nominal signal lines such as automotive sensor outputs or industrial I/O interfaces where steady-state voltage must remain unclamped.
Does VESD12-02V-G-08 meet IEC 61000-4-2 Level 4 ESD requirements?
Yes, VESD12-02V-G-08 is rated for ±8 kV contact discharge and ±15 kV air discharge per IEC 61000-4-2, satisfying Level 4-the highest severity level defined in the standard. This rating is verified across 10 pulses and applies directly to the VESD12-02V-G-08 device as specified in its official Vishay datasheet (Doc. #83367).
What is the clamping voltage of VESD12-02V-G-08 under a 2 A ESD pulse?
The VESD12-02V-G-08 exhibits a typical clamping voltage (VC) of 25 V when subjected to a 2 A peak pulse (8/20 μs waveform), as confirmed in the "Electrical Characteristics" table of its datasheet. This value ensures protected downstream ICs see no more than 25 V during an ESD event, well within safe operating limits for most 3.3 V or 5 V logic interfaces.
Can VESD12-02V-G-08 be used in USB 2.0 data line protection?
Yes, VESD12-02V-G-08 is appropriate for USB 2.0 D+ and D− line protection due to its 30 pF capacitance at 0 V bias and low leakage (<0.1 μA). These parameters prevent signal integrity loss and ensure eye diagram compliance, provided layout minimizes ground inductance-making VESD12-02V-G-08 a validated choice for embedded USB host/device ports.
Is VESD12-02V-G-08 RoHS-compliant and halogen-free?
Yes, VESD12-02V-G-08 conforms to RoHS Directive 2011/65/EU and JEDEC JS709A halogen-free standards, as certified by Vishay. Its e3 Sn termination, UL 94 V-0 molding compound, and MSL level 1 rating further confirm compliance with environmental and assembly requirements for modern electronics manufacturing.
