Product details
Overview
SMF9V0A-HM3-08 from Vishay Semiconductors is a unidirectional surface-mount ESD protection diode in DO-219AB (SOD-123W) package, rated for 9.0 V standoff voltage, 15.4 V max clamping voltage at 13.5 A peak pulse current, and ±30 kV IEC 61000-4-2 ESD immunity. It protects USB 2.0 data lines, HDMI interfaces, and industrial sensor inputs against transient overvoltage events.
For engineers reviewing the SMF9V0A-HM3-08 datasheet, SMF9V0A-HM3-08 pinout, SMF9V0A-HM3-08 application, or SMF9V0A-HM3-08 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, SOD-123W footprint compatibility, and real-world clamping performance under 10/1000 μs surge conditions - critical for automotive infotainment and industrial I/O design.
Technical Context
This device operates as a single-channel unidirectional TVS diode with avalanche breakdown behavior, designed to clamp transients before downstream ICs exceed absolute maximum ratings. Its low 0.1 μA reverse leakage at 9.0 V and 640 pF typical capacitance at 1 MHz enable use on high-speed signal lines without signal integrity degradation.
The SMF9V0A-HM3-08 uses silicon planar technology with "Low Noise" fast-response architecture, achieving sub-nanosecond turn-on time. It meets AEC-Q101 stress test requirements including HBM >8 kV and is qualified for operation from –65 °C to +175 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Clamping Voltage (VC) | 15.4 V max at IPPM = 13.5 A - Limits transient voltage seen by protected ICs during 10/1000 μs surges. |
| Peak Pulse Power | 200 W (10/1000 μs) - Sustains short-duration ESD and lightning-induced surges without failure. |
| ESD Immunity | ±30 kV contact / ±30 kV air per IEC 61000-4-2 - Exceeds Level 4 system-level ESD robustness requirements. |
| Capacitance | 640 pF at VR = 0 V, f = 1 MHz - Low enough for USB 2.0 (480 Mbps) and CAN FD signal integrity preservation. |
| AEC-Q101 Qualified | Yes - Validated for automotive applications including powertrain sensors and body control modules. |
| Package | DO-219AB (SOD-123W) - 3.9 mm × 1.9 mm × 1.08 mm low-profile outline compatible with automated SMT assembly. |
Pinout & Package
SMF9V0A-HM3-08 is housed in a two-terminal DO-219AB (SOD-123W) surface-mount package with cathode marked by a bar. The device has no internal circuitry beyond the PN junction; terminals are non-polarized in layout but functionally asymmetric (anode/cathode).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Ground reference terminal | Connected to system ground or low-impedance return path; defines clamping reference point for protected line. |
| Cathode (bar-marked end) | Signal line connection | Connected to I/O line being protected (e.g., USB D+, HDMI TMDS+); conducts surge current to ground when voltage exceeds VRWM. |

|---|---|
Use Scenario: Protecting host/device USB 2.0 data lines (D+/D−) from ESD events during cable insertion or handling. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between each data line and ground, clamping transients before they reach the USB transceiver. Use Value: Maintains 480 Mbps signaling integrity while limiting transient voltage to ≤15.4 V, preventing latch-up or oxide damage in PHY ICs. | Use Scenario: Safeguarding HDMI source/sink TMDS channels against electrostatic discharge during hot-plug events. IC Role / Device Role / Timing Role: Single-channel unidirectional clamp on each TMDS+ line referenced to ground, with cathode tied to signal. Use Value: 640 pF capacitance avoids skew between differential pairs; ±30 kV ESD rating ensures compliance with HDMI 1.4/2.0 system-level tests. |
| Automotive Sensor Interface | Industrial I/O Module |
Use Scenario: Protecting LIN bus or analog sensor inputs (e.g., pressure, temperature) in engine control units exposed to under-hood ESD. IC Role / Device Role / Timing Role: Standoff-rated TVS on signal line to chassis ground, activated only during overvoltage transients. Use Value: AEC-Q101 qualification and –65 °C to +175 °C operation ensure long-term reliability in harsh thermal environments. | Use Scenario: Shielding RS-485 transceiver inputs in programmable logic controller (PLC) I/O modules from field-induced surges. IC Role / Device Role / Timing Role: Primary front-end transient suppressor on differential bus lines, coordinated with secondary GDT or MOV stages. Use Value: 200 W peak pulse power handles repetitive 10/1000 μs surges common in factory floor EMI environments without parametric shift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ9.0A | Higher clamping voltage (17.5 V), larger SMA package (4.5 mm × 2.7 mm), 500 W peak power (8/20 μs) | Better suited for higher-energy surges but less space-efficient and higher capacitance (800 pF) | Select SMAJ9.0A only when 200 W pulse power is insufficient and board area allows larger footprint. |
| TPD2E001DRYR | Two-channel bidirectional array, 12 pF capacitance, 3.6 V standoff, not AEC-Q101 qualified | Optimized for ultra-high-speed USB 3.0/DisplayPort, not rated for automotive or industrial surge levels | Choose TPD2E001DRYR for portable consumer devices requiring minimal capacitance, not for automotive or industrial use. |
Compared with SMAJ9.0A and TPD2E001DRYR, the SMF9V0A-HM3-08 uniquely balances AEC-Q101 qualification, compact DO-219AB size, and 640 pF capacitance - making it optimal for space-constrained automotive and industrial signal-line protection where both ESD and surge robustness are required.

FAQ
What is the standoff voltage rating of the SMF9V0A-HM3-08?
The SMF9V0A-HM3-08 has a maximum standoff voltage (VRWM) of 9.0 V, meaning it remains in high-impedance state up to this reverse voltage level with only 0.1 μA leakage current. This rating ensures compatibility with 5 V and 9 V logic systems while providing sufficient margin before clamping activation. The SMF9V0A-HM3-08 maintains stable operation across its full –65 °C to +175 °C junction temperature range.
Is the SMF9V0A-HM3-08 qualified to AEC-Q101 standards?
Yes, the SMF9V0A-HM3-08 is AEC-Q101 qualified, having passed all required stress tests including human body model ESD >8 kV, temperature cycling, and high-temperature operating life. This qualification confirms its suitability for automotive applications such as engine control units, body electronics, and infotainment systems. The SMF9V0A-HM3-08 carries the "H" suffix in its ordering code to denote AEC-Q101 compliance.
What is the clamping voltage of the SMF9V0A-HM3-08 under surge conditions?
The SMF9V0A-HM3-08 exhibits a maximum clamping voltage (VC) of 15.4 V at 13.5 A peak pulse current using the 10/1000 μs waveform. This value represents the upper limit of voltage imposed on the protected line during transient events, ensuring downstream ICs remain within safe operating limits. The SMF9V0A-HM3-08 achieves this clamping performance with low incremental surge resistance and fast response enabled by its "Low Noise" silicon structure.
Can the SMF9V0A-HM3-08 be used in USB 2.0 applications?
Yes, the SMF9V0A-HM3-08 is suitable for USB 2.0 data line protection due to its 640 pF capacitance at 0 V and 15.4 V clamping voltage, which preserves signal integrity at 480 Mbps while suppressing ESD events. Its DO-219AB package fits high-density layouts, and ±30 kV IEC 61000-4-2 rating exceeds USB compliance requirements. The SMF9V0A-HM3-08 is commonly deployed on D+ and D− lines adjacent to USB connectors in host and peripheral designs.
What package type does the SMF9V0A-HM3-08 use, and what are its dimensions?
The SMF9V0A-HM3-08 uses the DO-219AB (SOD-123W) surface-mount package, measuring 3.9 mm in length, 1.9 mm in width, and 1.08 mm in height. Its low-profile design supports automated placement and reflow soldering, and the cathode is marked by a visible bar on the top surface. The SMF9V0A-HM3-08 footprint matches JEDEC-standard SOD-123W land patterns, enabling drop-in compatibility with existing designs using that outline.
