Product details
Overview
SMF6V0A-HE3_A08 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 6 V standoff voltage, 10.3 V maximum clamping voltage at 19.4 A peak pulse current, ±30 kV IEC 61000-4-2 ESD immunity, and 200 W peak pulse power (10/1000 μs). It is AEC-Q101 qualified and used in USB 2.0, HDMI, and automotive infotainment interfaces.
For engineers reviewing the SMF6V0A-HE3_A08 datasheet, SMF6V0A-HE3_A08 pinout, SMF6V0A-HE3_A08 application, or SMF6V0A-HE3_A08 equivalent, this page delivers verified electrical parameters, package dimensions, clamping behavior under surge conditions, thermal resistance (180 K/W), and real-world ESD protection use cases - all critical for signal integrity validation and board-level robustness design.
Technical Context
The SMF6V0A-HE3_A08 operates as a single-channel unidirectional TVS diode with avalanche breakdown mechanism, optimized for fast response (<1 ns) to electrostatic discharge events. Its low incremental surge resistance ensures minimal voltage overshoot during transient suppression, while its 1063 pF typical capacitance at 0 V enables compatibility with 480 Mbps USB 2.0 signaling without significant signal degradation.
It complies with IEC 61000-4-2 (±30 kV contact/air) and AEC-Q101 Class H3B (>8 kV HBM), supporting operation across -65 °C to +175 °C. The device uses "Low Noise" technology and is rated for 1000 W peak pulse power per IEC 61000-4-5 (8/20 μs), with thermal resistance measured on 3 mm × 3 mm Cu pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VRWM) | 6 V - Maximum continuous reverse voltage before leakage exceeds 26 µA; sets operating margin for 5 V logic rails. |
| Clamping Voltage (VC) | 10.3 V at 19.4 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 transients without failure; sufficient for most board-level ESD events. |
| Capacitance (CD) | 1063 pF at 0 V, 1 MHz - Low enough for USB 2.0 full-speed operation but not suitable for USB 3.x or PCIe Gen3+. |
| ESD Rating | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - Meets highest industrial and automotive ESD immunity requirements. |
| Junction Temp Range | -65 °C to +175 °C - Enables deployment in under-hood automotive environments and industrial control enclosures. |
Pinout & Package
The SMF6V0A-HE3_A08 is housed in the DO-219AB (SMF) package: low-profile (1.08 mm height), SOD-123W-compatible outline, molded in UL 94 V-0 compound, MSL level 1, and reflow-solderable up to 260 °C peak temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Input side of protection path | Connected to signal line being protected; conducts surge current toward cathode during overvoltage event. |
| Cathode (Pin 2) | Ground reference terminal | Connected to system ground or low-impedance return path; defines unidirectional conduction direction and clamping reference. |
Key Features
| Feature | Design Value |
|---|---|

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-E3/5A | Higher clamping voltage (10.5 V), larger SMA package (4.5 mm × 2.7 mm), 600 W peak power (10/1000 µs) | Less suitable for space-constrained USB/HDMI layouts; better for higher-energy surges in power supply rails | Select when board layout permits larger footprint and higher surge energy handling is prioritized over capacitance. |
| TPD2E001DRYR | Bi-directional, 1.5 pF capacitance, 5 V VRWM, integrated dual-channel array in SOT-553 | Designed for ultra-high-speed interfaces (USB 3.0, MIPI); not AEC-Q101 qualified | Choose for sub-5 Gbps serial links where <2 pF capacitance is mandatory and automotive qualification is not required. |
Compared with SMAJ6.0A-E3/5A and TPD2E001DRYR, the SMF6V0A-HE3_A08 offers optimal balance of AEC-Q101 compliance, 1063 pF capacitance for USB 2.0, compact DO-219AB footprint, and ±30 kV ESD rating - making it the preferred choice for cost-sensitive, thermally demanding automotive and industrial data-line protection.

FAQ
What is the standoff voltage of the SMF6V0A-HE3_A08?
The SMF6V0A-HE3_A08 has a maximum standoff voltage (VRWM) of 6 V, meaning it remains non-conductive up to this reverse voltage level while leaking less than 26 µA. This value is critical for ensuring compatibility with 5 V logic systems, as it provides sufficient margin above nominal rail voltage while preventing false triggering during normal operation. The SMF6V0A-HE3_A08 maintains this rating across its full operating temperature range.
Is the SMF6V0A-HE3_A08 AEC-Q101 qualified?
Yes, the SMF6V0A-HE3_A08 is AEC-Q101 qualified and certified to Class H3B for human body model ESD (>8 kV), making it suitable for automotive applications including infotainment, ADAS camera links, and body control modules. This qualification covers stress tests for temperature cycling, mechanical shock, and high-temperature operating life. The SMF6V0A-HE3_A08 meets these requirements in its DO-219AB package with no derating needed.
What is the clamping voltage of the SMF6V0A-HE3_A08 at rated surge current?
The SMF6V0A-HE3_A08 exhibits a maximum clamping voltage (VC) of 10.3 V when subjected to its rated peak pulse current of 19.4 A using a 10/1000 µs waveform. This clamping performance ensures protected downstream ICs-such as USB transceivers or HDMI drivers-remain within their absolute maximum voltage ratings during ESD events. The SMF6V0A-HE3_A08 achieves this with low incremental surge resistance and fast avalanche response.
Can the SMF6V0A-HE3_A08 be used in USB 3.0 or higher-speed interfaces?
No, the SMF6V0A-HE3_A08 is not recommended for USB 3.0, USB 3.1, or PCIe interfaces due to its 1063 pF typical capacitance at 0 V, which would severely degrade signal integrity at multi-Gbps data rates. It is specifically optimized for USB 2.0 (480 Mbps), HDMI 1.4, and other sub-1 Gbps serial links. For higher-speed applications, lower-capacitance alternatives like the TPD2E001DRYR (1.5 pF) should be considered instead of the SMF6V0A-HE3_A08.
What package type does the SMF6V0A-HE3_A08 use, and what are its key mechanical features?
The SMF6V0A-HE3_A08 uses the DO-219AB (SMF) package: a low-profile surface-mount outline measuring 3.9 mm × 1.9 mm × 1.08 mm, with UL 94 V-0 molding compound and MSL level 1 moisture sensitivity. Its cathode-bar marking and SOD-123W-compatible footprint enable drop-in compatibility with existing layouts. The SMF6V0A-HE3_A08 supports wave and reflow soldering up to 260 °C peak temperature without preconditioning.
