Product details
Overview
SMF6V0A-HM3-08 from Vishay Semiconductors is a unidirectional surface-mount ESD protection diode in DO-219AB (SOD-123W) package, designed for low-capacitance transient suppression on high-speed data lines. It features 6.67 V minimum breakdown voltage, 10.3 V maximum clamping voltage at 19.4 A peak pulse current, 1063 pF typical capacitance at 0 V, ±30 kV IEC 61000-4-2 ESD immunity, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMF6V0A-HM3-08 datasheet, SMF6V0A-HM3-08 pinout, SMF6V0A-HM3-08 application, or SMF6V0A-HM3-08 equivalent, this page delivers verified electrical specs, package dimensions, real-world clamping behavior, automotive-grade reliability data, and direct alternatives for USB 2.0, HDMI, and CAN FD interface protection.
Technical Context
This diode operates as a unidirectional TVS device with avalanche breakdown mechanism, optimized for fast response (<1 ns) to ESD transients per IEC 61000-4-2. Its low incremental surge resistance ensures tight clamping during 10/1000 μs surges, while its 1063 pF capacitance at 0 V supports signal integrity on lines up to 480 Mbps.
The SMF6V0A-HM3-08 uses silicon planar technology with cathode-bar marking, conforms to SOD-123W footprint, and is rated for continuous operation from –65 °C to +175 °C - matching under-hood and infotainment system thermal requirements without derating.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A-E3/57T | Higher 11.4 V clamping at 16.7 A; SMA package (larger footprint, 4.5 mm × 2.7 mm) | Less suitable for space-constrained USB/HDMI layouts; better for higher-energy surges | Choose when board area allows larger package and clamping margin >11 V is acceptable |
| TPD2E001DRYR | 2-channel array, 12 pF @ 0 V, 12 V clamping; integrated dual-diode + resistor network | Designed specifically for USB 2.0 D+/D−; not automotive-qualified | Prefer for consumer USB ports where ultra-low capacitance is critical and AEC-Q101 not required |
Compared with SMAJ6.0A-E3/57T and TPD2E001DRYR, the SMF6V0A-HM3-08 offers optimal balance of automotive qualification, compact DO-219AB size, and 10.3 V clamping - making it the preferred choice for space-limited, high-reliability CAN FD and infotainment interfaces.

FAQ
What is the maximum clamping voltage of SMF6V0A-HM3-08 under IEC 61000-4-5 surge conditions?
The SMF6V0A-HM3-08 has a maximum clamping voltage of 10.3 V when subjected to a 19.4 A peak pulse current with a 10/1000 μs waveform - the standard test condition defined in IEC 61000-4-5 for surge immunity validation. This value is measured per Vishay's datasheet Rev. 2.4 and ensures safe operation for 5 V logic interfaces. The SMF6V0A-HM3-08 maintains this clamping performance across its full operating temperature range.
Is SMF6V0A-HM3-08 suitable for protecting USB 2.0 high-speed data lines?
Yes, the SMF6V0A-HM3-08 is suitable for USB 2.0 full-speed (12 Mbps) and high-speed (480 Mbps) data lines due to its 1063 pF capacitance at 0 V and 6 V stand-off voltage - both within acceptable limits for signal integrity. Its low clamping voltage (10.3 V) prevents overvoltage stress on PHY transceivers. The SMF6V0A-HM3-08 is widely deployed in automotive USB hubs and infotainment head units where ESD robustness is critical.
Does SMF6V0A-HM3-08 meet AEC-Q101 requirements for automotive applications?
Yes, the SMF6V0A-HM3-08 is explicitly AEC-Q101 qualified per Vishay's documentation, supporting use in automotive powertrain, body electronics, and ADAS systems. It passes stress tests including temperature cycling, humidity bias, and ESD per human body model (H3B, >8 kV). The SMF6V0A-HM3-08's -65 °C to +175 °C operating range and DO-219AB package stability make it appropriate for under-hood and dashboard environments.
What is the reverse leakage current specification for SMF6V0A-HM3-08 at rated stand-off voltage?
The SMF6V0A-HM3-08 exhibits a maximum reverse leakage current of 26 µA at its 6 V stand-off voltage (VRWM) and 25 °C ambient temperature, as specified in the Electrical Characteristics table. This low leakage ensures minimal impact on high-impedance signal paths such as I²C DDC lines or sensor interfaces. The SMF6V0A-HM3-08 maintains leakage below 100 µA even at 125 °C, supporting reliable operation in thermally demanding applications.
How does the DO-219AB package of SMF6V0A-HM3-08 compare to standard SOD-123 in layout compatibility?
The DO-219AB package used by SMF6V0A-HM3-08 is dimensionally identical to SOD-123W and mechanically compatible with SOD-123F/FL footprints - all share 3.9 mm length, 1.9 mm width, and 1.08 mm height. The SMF6V0A-HM3-08's cathode bar orientation matches industry-standard tape-and-reel placement (per Vishay's orientation diagram), enabling drop-in replacement in existing SOD-123 layouts without PCB redesign. Its MSL level 1 rating simplifies manufacturing flow.
