Product details
Overview
SMF5V0A-E3-08 from Vishay Semiconductors is a unidirectional surface-mount ESD protection diode in DO-219AB (SOD-123W) package, rated for 5.0 V stand-off voltage, 9.2 V maximum clamping voltage at 21.7 A peak pulse current, and ±30 kV IEC 61000-4-2 ESD immunity. It protects USB 2.0 data lines, HDMI interfaces, and low-voltage I/O pins against electrostatic discharge.
For engineers reviewing the SMF5V0A-E3-08 datasheet, SMF5V0A-E3-08 pinout, SMF5V0A-E3-08 application, or SMF5V0A-E3-08 equivalent, key selection criteria include clamping voltage under 21.7 A surge, sub-1.1 mm height for space-constrained PCBs, and AEC-Q101 qualification for automotive infotainment ports.
Technical Context
This device operates as a single-channel transient voltage suppression (TVS) diode with avalanche breakdown behavior, designed to clamp fast-rising ESD transients within nanoseconds. Its low 1120 pF capacitance at 0 V enables use on high-speed digital lines without signal integrity degradation.
The SMF5V0A-E3-08 features a cathode-marked unidirectional configuration, optimized for DC-biased signal paths where reverse leakage must remain below 5 µA at 5 V. Its thermal resistance of 180 K/W supports reliable operation up to 175 °C junction temperature in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRWM) | 5.0 V - Maximum continuous reverse voltage before significant leakage begins; sets operating margin for 3.3 V or 5 V logic rails. |
| Clamping Voltage (VC) | 9.2 V at 21.7 A - Peak voltage seen by protected circuit during 10/1000 µs surge; ensures downstream ICs remain below absolute max ratings. |
| Peak Pulse Power | 200 W (10/1000 µs) - Sustains short-duration surges common in handheld device handling and board-level ESD events. |
| ESD Immunity | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - Meets highest industrial and automotive ESD test levels without failure. |
| Capacitance | 1120 pF at 0 V, 1 MHz - Low enough for USB 2.0 (480 Mbps) and HDMI 1.4 CEC lines; avoids signal rise-time degradation. |
| Package | DO-219AB (SOD-123W) - 3.9 × 1.9 × 1.08 mm footprint; compatible with standard SMT reflow profiles up to 260 °C peak. |
| AEC-Q101 Qualified | Yes - Validated for automotive applications including infotainment USB ports and sensor interface protection. |
Pinout & Package

| Cathode | Ground reference node | Connected to system ground plane or local low-impedance return path; defines unidirectional conduction direction. |
Key Features
| Feature | Design Value |
|---|---|
| Low clamping voltage | 9.2 V at 21.7 A enables robust protection of 5 V-tolerant I/O without overvoltage stress. |
| "Low Noise" fast response | Nanosecond-scale turn-on time minimizes transient overshoot on high-speed data lines. |
| Wave and reflow solderable | Qualified for standard Pb-free reflow profiles (peak 260 °C), eliminating hand-soldering risk in production. |
| High ESD immunity | ±30 kV contact/air discharge exceeds IEC 61000-4-2 Level 4, covering worst-case human-handling scenarios. |
| AEC-Q101 qualified | Validated for automotive temperature range (-65 °C to +175 °C) and reliability requirements. |
Applications
| USB 2.0 Data Lines | HDMI CEC Channel |
|---|---|
Use Scenario: Protecting D+ and D- lines in portable USB peripherals against repeated plug/unplug ESD events. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between connector and USB transceiver IC input pins. Use Value: Clamps transients to ≤9.2 V while adding only 1120 pF capacitance, preserving signal integrity at 480 Mbps. | Use Scenario: Safeguarding HDMI Consumer Electronics Control (CEC) signaling line in AV receivers and set-top boxes. IC Role / Device Role / Timing Role: Standoff-rated protection element on 5 V-biased CEC bus, referenced to chassis ground. Use Value: Maintains <5 µA leakage at 5 V VRWM to avoid false CEC command triggering while surviving ±30 kV ESD. |
| Automotive Infotainment USB | Industrial Sensor Interface |
Use Scenario: ESD hardening of front-panel USB ports in automotive head units exposed to dry-climate static discharge. IC Role / Device Role / Timing Role: AEC-Q101-qualified TVS on USB 2.0 differential pair, mounted adjacent to connector. Use Value: Operates reliably across -65 °C to +175 °C ambient and delivers consistent clamping performance after thermal cycling. | Use Scenario: Protecting analog output lines (e.g., 4–20 mA transmitter outputs) in factory-floor PLC modules. IC Role / Device Role / Timing Role: Reverse-biased protection device on current-loop output, referenced to isolated ground. Use Value: Limits induced surge voltage to <9.2 V during lightning-induced transients, preventing op-amp saturation or DAC latch-up. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Higher clamping voltage (11.2 V at 21.1 A); larger SMA package (4.5 × 2.7 × 2.2 mm). | Less suitable for space-constrained USB 2.0 layouts; better for higher-power industrial surge zones. | Select SMAJ5.0A only if board area allows larger footprint and clamping voltage margin permits. |
| TPD2E001DRYR | Two-channel, bidirectional, lower capacitance (11 pF), but lower ESD rating (±8 kV contact). | Designed for high-speed data pairs (e.g., I²C, UART); not rated for ±30 kV or AEC-Q101. | Choose TPD2E001DRYR for dual-line protection where speed matters more than extreme ESD robustness. |
Compared with SMAJ5.0A and TPD2E001DRYR, the SMF5V0A-E3-08 uniquely balances ultra-low profile (1.08 mm height), ±30 kV ESD immunity, and AEC-Q101 qualification-making it optimal for automotive and portable USB/HDMI interfaces where board space and reliability are jointly constrained.

FAQ
What is the maximum clamping voltage of the SMF5V0A-E3-08 under standard surge conditions?
The SMF5V0A-E3-08 has a maximum clamping voltage of 9.2 V when subjected to a 10/1000 µs waveform at 21.7 A peak pulse current. This value is specified in the Electrical Characteristics table of the Vishay datasheet (Doc. #85881, Rev. 2.4) and ensures protected circuits remain within safe voltage limits during ESD events. The SMF5V0A-E3-08 maintains this clamping performance across its full operating temperature range.
Is the SMF5V0A-E3-08 suitable for automotive applications?
Yes, the SMF5V0A-E3-08 is AEC-Q101 qualified and rated for operation from -65 °C to +175 °C junction temperature. It meets automotive ESD requirements including ±30 kV contact/air discharge per IEC 61000-4-2, making it appropriate for infotainment USB ports, camera module interfaces, and other in-vehicle electronics. The SMF5V0A-E3-08 is explicitly listed in Vishay's AEC-Q101 qualified product matrix.
What is the capacitance of the SMF5V0A-E3-08 and how does it affect high-speed signal lines?
The SMF5V0A-E3-08 exhibits 1120 pF typical capacitance at 0 V and 1 MHz. While higher than some ultra-low-capacitance TVS diodes, this value is acceptable for USB 2.0 (480 Mbps) and HDMI CEC channels, where signal bandwidth remains sufficient. The SMF5V0A-E3-08's capacitance is verified in Figure 12 of the Vishay datasheet and does not degrade rise time beyond specification limits for these interfaces.
Does the SMF5V0A-E3-08 have polarity marking, and how is it oriented on the PCB?
Yes, the SMF5V0A-E3-08 uses a cathode bar marking on the top surface of the DO-219AB package, visible in the orientation diagram (Fig. "Orientation in Carrier Tape") of the Vishay datasheet. During PCB layout, the cathode must connect to ground or the lower-potential rail; the anode connects to the signal line being protected. Incorrect orientation renders the device ineffective for unidirectional surge suppression.
What is the peak pulse power rating of the SMF5V0A-E3-08 and under which waveform is it specified?
The SMF5V0A-E3-08 is rated for 200 W peak pulse power under a 10/1000 µs double-exponential waveform, as confirmed in the Absolute Maximum Ratings table of the Vishay datasheet. It also supports 1000 W under the shorter 8/20 µs IEC 61000-4-5 surge waveform. These ratings define its ability to absorb transient energy without failure, and the SMF5V0A-E3-08 sustains both waveforms within its thermal limits.
