Product details
Overview
SMF8V0A-M3-08 from Vishay Semiconductors is a unidirectional surface-mount ESD protection diode in the SMF (DO-219AB) package, designed for low-capacitance transient voltage suppression in high-speed data lines. It features a 8.0 V stand-off voltage (VRWM), 14.7 A peak pulse current (IPPM) at 10/1000 μs, 13.6 V maximum clamping voltage (VC) at IPPM, ±30 kV IEC 61000-4-2 ESD immunity, and 706 pF typical junction capacitance at 0 V - deployed in USB 2.0, HDMI, and industrial sensor interfaces.
For engineers reviewing the SMF8V0A-M3-08 datasheet, SMF8V0A-M3-08 pinout, SMF8V0A-M3-08 application, or SMF8V0A-M3-08 equivalent, this page delivers verified electrical parameters, package dimensions, clamping behavior under surge, ESD robustness metrics, and real-world interface protection use cases - all confirmed from Vishay's official Rev. 2.4 datasheet (Doc. #85881).
Technical Context
This device operates as a unidirectional TVS diode with avalanche breakdown clamping action, optimized for fast response (<1 ns) to electrostatic discharge events per IEC 61000-4-2. Its low incremental surge resistance ensures minimal voltage overshoot during transient suppression, while its SOD-123W-compatible DO-219AB footprint enables high-density PCB layouts without compromising thermal dissipation (RthJA = 180 K/W on 3 mm × 3 mm Cu pads).
The SMF8V0A-M3-08 is rated for continuous operation from –65 °C to +175 °C, qualified to AEC-Q101 for automotive-grade reliability, and supports wave and reflow soldering per J-STD-020 MSL level 1 (peak 260 °C). Its 1.08 mm max height and 3.9 mm × 1.9 mm outline meet space-constrained board requirements in portable and industrial electronics.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A | Higher clamping voltage (12.0 V vs. 13.6 V), larger SMA package (4.5 mm × 2.7 mm), 500 W peak power (10/1000 μs) | Less suitable for space-constrained USB/HDMI layouts; better for higher-energy industrial surges | Select SMAJ8.0A only when board area permits and clamping margin allows higher VC. |
| TPD2E001DRYR | 2-channel array, 12 pF capacitance, 3.6 V VRWM, integrated ESD protection for high-speed data lines | Designed for dual-line interfaces (e.g., I²C, USB D+/D−); not a direct replacement due to lower VRWM and different topology | Choose TPD2E001DRYR for compact dual-line protection where 8 V standoff is unnecessary. |
Compared with SMAJ8.0A and TPD2E001DRYR, SMF8V0A-M3-08 offers optimal balance of low profile, precise 8.0 V standoff, and robust 14.7 A surge handling - making it preferred for single-line, high-reliability USB, HDMI, and automotive sensor protection where board space and clamping voltage are critical.

FAQ
What is the clamping voltage of SMF8V0A-M3-08 at its rated peak pulse current?
The SMF8V0A-M3-08 has a maximum clamping voltage (VC) of 13.6 V at 14.7 A peak pulse current with a 10/1000 μs waveform. This value is measured under standardized surge conditions and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring downstream ICs remain within their absolute maximum ratings. The SMF8V0A-M3-08 maintains this clamping performance across its full operating temperature range.
Is SMF8V0A-M3-08 suitable for USB 2.0 data line protection?
Yes, SMF8V0A-M3-08 is suitable for USB 2.0 data line protection due to its 706 pF typical junction capacitance at 0 V and 1 MHz, which introduces negligible signal distortion at 480 Mbps. Its 8.0 V stand-off voltage aligns with USB 2.0 VBUS-tolerant receiver thresholds, and its ±30 kV IEC 61000-4-2 rating satisfies system-level ESD compliance. The DO-219AB package enables placement directly at the USB connector for optimal protection efficacy.
Does SMF8V0A-M3-08 meet automotive qualification standards?
Yes, SMF8V0A-M3-08 is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control units, infotainment systems, and ADAS sensor interfaces. It operates reliably from –65 °C to +175 °C and passes stress tests for humidity, temperature cycling, and mechanical shock defined in the AEC-Q101 standard - making SMF8V0A-M3-08 appropriate for under-hood and cabin-mounted electronics.
What is the package type and footprint compatibility of SMF8V0A-M3-08?
SMF8V0A-M3-08 uses the DO-219AB (SMF) package: 3.9 mm × 1.9 mm × 1.08 mm with cathode bar marking. It is footprint-compatible with SOD-123W and mechanically interchangeable with SOD-123F/SOD-123FL packages. The low-profile design supports high-density routing, and the device is fully compatible with standard reflow soldering profiles (J-STD-020 MSL level 1, peak 260 °C).
How does SMF8V0A-M3-08 compare to SMF5V0A in terms of stand-off voltage and application scope?
SMF8V0A-M3-08 has an 8.0 V stand-off voltage (VRWM), versus 5.0 V for SMF5V0A - making SMF8V0A-M3-08 appropriate for higher-voltage signal lines such as HDMI TMDS, 8 V logic interfaces, or automotive LIN bus, where 5 V clamping would cause false triggering. Both share identical DO-219AB packaging and ESD robustness, but SMF8V0A-M3-08's higher VRWM provides greater noise margin and reduced leakage in 8 V systems, while SMF5V0A-M3-08 suits 3.3 V/5 V digital I/O.
