Product details
Overview
SMF7V0A-M3-08 from Vishay Semiconductors is a unidirectional surface-mount ESD protection diode in the SMF (DO-219AB) package, designed for low-capacitance transient suppression on high-speed data lines. It features a 7.0 V stand-off voltage (VRWM), 7.78–8.6 V reverse breakdown (VBR), 12 V maximum clamping voltage at 16.7 A peak pulse current (VC), 843 pF typical capacitance at 0 V, and ±30 kV IEC 61000-4-2 ESD immunity - deployed in USB 2.0, HDMI, and automotive infotainment interfaces.
For engineers reviewing the SMF7V0A-M3-08 datasheet, SMF7V0A-M3-08 pinout, SMF7V0A-M3-08 application, or SMF7V0A-M3-08 equivalent, this device is selected for robust electrostatic discharge protection where low clamping voltage, sub-1 ns response time, and minimal signal distortion on 5–12 V DC rails are required.
Technical Context
The SMF7V0A-M3-08 operates as a single-channel unidirectional TVS diode with avalanche breakdown behavior, optimized for fast transient suppression in low-voltage digital interfaces. Its junction structure delivers <1 ns response time and low incremental surge resistance, enabling effective clamping of ESD events before downstream ICs are damaged.
It complies with AEC-Q101 for automotive-grade reliability and supports wave/reeflow soldering per J-STD-020 MSL level 1. The device maintains stable performance across -65 °C to +175 °C operating temperature and exhibits 180 K/W thermal resistance when mounted on standard 3 mm × 3 mm Cu pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRWM) | 7.0 V - Maximum continuous reverse voltage before leakage exceeds 3 µA; sets operating margin for 5 V or 7 V supply rails. |
| Breakdown Voltage (VBR) | 7.78–8.6 V at 10 mA - Confirmed avalanche onset range; ensures reliable triggering above normal operating voltage. |
| Clamping Voltage (VC) | 12.0 V at 16.7 A (10/1000 µs) - Peak voltage seen by protected circuit during worst-case surge; limits stress on 12 V-tolerant receivers. |
| Capacitance (CD) | 843 pF at 0 V, 1 MHz - Measured signal-line loading; suitable for USB 2.0 (≤480 Mbps) but not USB 3.x or PCIe Gen3. |
| ESD Rating | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - Full compliance with Level 4 industrial and automotive ESD requirements. |
| Peak Pulse Power | 200 W (10/1000 µs) - Sustains short-duration transients without degradation; validated per IEC 61000-4-5 waveform. |
| Package | DO-219AB (SOD-123W-compatible) - Low-profile 3.9 × 1.9 × 1.08 mm outline; enables dense PCB layouts and automated assembly. |
Pinout & Package
SMF7V0A-M3-08 uses the DO-219AB (SMF) package: an asymmetrical surface-mount case with cathode marking bar, 3.9 mm length, 1.9 mm width, and 1.08 mm height. It is compatible with SOD-123W footprint and reflow-solderable per JEDEC J-STD-020.

|---|---|
|
Use Scenario: Protecting differential USB 2.0 D+ and D− lines against ESD events during cable insertion or handling. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between each data line and ground, clamping surges before they reach the USB transceiver. Use Value: 843 pF capacitance avoids signal integrity degradation at 480 Mbps; 12 V clamping preserves 3.3 V IO tolerance of host/device PHYs. |

IC Role / Device Role / Timing Role: AEC-Q101-qualified transient suppressor on low-voltage analog/digital signal paths exposed to user interaction. Use Value: -65 °C to +175 °C operating range supports under-dash thermal environments; ±30 kV ESD rating exceeds ISO 10605 requirements. |
Use Scenario: Protecting 4–20 mA loop-powered sensor outputs or RS-485 transceiver pins in factory automation systems. IC Role / Device Role / Timing Role: Bidirectional-capable unidirectional clamp (with external grounding strategy) on 7–12 V signal rails subject to field ESD. Use Value: 200 W peak pulse power handles induced surges from nearby relay switching; DO-219AB package withstands mechanical vibration. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.0A-E3/57T | DO-214AC (SMA) package; 1.5 mm taller; 200 W rating same, but 13.3 V clamping at 15.2 A. | Higher profile limits use in ultra-thin devices; higher VC reduces margin for 3.3 V logic. | Select when legacy SMA footprint exists or board space allows larger body. |
| TPD2E001DRYR | 2-channel, 0.8 pF per line, 5.5 V VRWM; integrated dual-diode array in USON-6. | Designed for high-speed USB 3.0/MIPI; insufficient for 7 V rail protection or 30 kV ESD. | Choose only for multi-line, ultra-low-capacitance needs below 6 V - not a direct replacement for SMF7V0A-M3-08. |
Compared with SMAJ7.0A-E3/57T and TPD2E001DRYR, SMF7V0A-M3-08 offers lower profile, tighter clamping (12.0 V vs. 13.3 V), and verified 30 kV ESD performance - making it optimal for space-constrained 7 V interface protection where robustness outweighs ultra-low capacitance needs.

FAQ
What is the maximum clamping voltage of the SMF7V0A-M3-08 under a 10/1000 µs surge?
The SMF7V0A-M3-08 has a maximum clamping voltage (VC) of 12.0 V when subjected to a 16.7 A peak pulse current with a 10/1000 µs waveform. This value is measured per IEC 61000-4-5 test conditions and ensures downstream 12 V-tolerant ICs remain within safe operating limits during transient events. The SMF7V0A-M3-08 achieves this while maintaining low incremental surge resistance and fast response.
Is the SMF7V0A-M3-08 suitable for protecting USB 2.0 high-speed data lines?
Yes, the SMF7V0A-M3-08 is suitable for USB 2.0 data line protection due to its 843 pF typical capacitance at 0 V and 1 MHz, which introduces negligible signal distortion at 480 Mbps. Its 7.0 V stand-off voltage aligns with USB 2.0 VBUS and I/O voltage margins, and its ±30 kV ESD rating exceeds IEC 61000-4-2 Level 4 requirements. The SMF7V0A-M3-08 must be placed close to the connector with symmetric layout to preserve differential impedance.
Does the SMF7V0A-M3-08 meet automotive qualification standards?
Yes, the SMF7V0A-M3-08 is AEC-Q101 qualified for automotive applications, having passed stress tests including high-temperature operating life, temperature cycling, and ESD robustness. It operates across -65 °C to +175 °C and is rated for under-hood and infotainment use. The SMF7V0A-M3-08 is commonly deployed on touch panel interfaces, audio amplifiers, and LIN bus nodes in production vehicles.
What is the package type and soldering compatibility of the SMF7V0A-M3-08?
The SMF7V0A-M3-08 uses the DO-219AB (SMF) package - a low-profile 3.9 mm × 1.9 mm × 1.08 mm surface-mount outline compatible with SOD-123W footprints. It supports both wave and reflow soldering per J-STD-020, with peak temperature tolerance up to 260 °C and MSL level 1 rating. The SMF7V0A-M3-08 requires no special pre-bake or handling and is fully compatible with standard SMT assembly lines.
How does the SMF7V0A-M3-08 compare to bidirectional TVS diodes for ESD protection?
The SMF7V0A-M3-08 is unidirectional and optimized for DC-biased lines like USB D+/D− or HDMI DDC, where one side is referenced to ground. Unlike bidirectional variants, it provides lower leakage (<3 µA at 7 V) and tighter clamping (12.0 V) for positive transients. For AC-coupled or floating lines, a bidirectional part would be needed - but the SMF7V0A-M3-08 delivers superior performance where polarity is known and ground-referenced protection is sufficient.
