Product details
Overview
SMF6V0A-HM3-18 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 6.0 V stand-off voltage (VRWM), 10.3 V maximum clamping voltage at 19.4 A peak pulse current, 1063 pF typical junction capacitance at 0 V, ±30 kV IEC 61000-4-2 ESD immunity, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMF6V0A-HM3-18 datasheet, SMF6V0A-HM3-18 pinout, SMF6V0A-HM3-18 application, or SMF6V0A-HM3-18 equivalent, this device is selected for robust electrostatic discharge protection in USB 2.0, HDMI, automotive infotainment interfaces, and industrial sensor signal conditioning where low clamping voltage and fast response time are critical.
Technical Context
This unidirectional TVS diode operates as a reverse-biased clamp, triggering at 6.67 V minimum breakdown (VBR) and limiting transients to ≤10.3 V at 19.4 A (10/1000 μs). Its low 1063 pF capacitance minimizes signal distortion on 480 Mbps USB 2.0 lines while maintaining <1 ns response time via "Low Noise" silicon technology.
The SMF6V0A-HM3-18 uses a planar junction structure in a SOD-123W-compatible DO-219AB package with MSL level 1 moisture sensitivity, rated for -65 °C to +175 °C operation and qualified to AEC-Q101 for under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRWM) | 6.0 V - Maximum continuous reverse voltage before clamping begins; sets operating margin above 5 V logic rails. |
| Clamping Voltage (VC) | 10.3 V at 19.4 A (10/1000 μs) - Limits transient energy delivered to protected ICs; ensures downstream 12 V tolerant receivers remain undamaged. |
| Junction Capacitance (CD) | 1063 pF at 0 V, 1 MHz - Low enough for USB 2.0 full-speed signaling without measurable eye diagram degradation. |
| ESD Withstand | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - Exceeds Level 4 immunity requirements for consumer and automotive end-equipment. |
| AEC-Q101 Qualified | Yes - Validated for automotive applications including infotainment, body control modules, and ADAS sensor interfaces. |
| Package | DO-219AB (SOD-123W footprint) - 3.9 mm × 1.9 mm × 1.08 mm low-profile outline compatible with automated SMT assembly and reflow profiles up to 260 °C. |
Pinout & Package
SMF6V0A-HM3-18 is housed in the DO-219AB (SMF) package: a two-terminal, cathode-marked, surface-mount plastic case with dimensions 3.9 mm × 1.9 mm × 1.08 mm and MSL level 1 rating. The cathode bar is located at terminal 2 per standard orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Terminal 2 (Cathode) | Ground reference | Connected to system ground or low-impedance return path; establishes clamping reference and completes transient current loop. |
Key Features
| Feature | Design Value |
|---|---|
| 200 W Peak Pulse Power (10/1000 μs) | Handles repetitive ESD and lightning-induced surges in industrial and automotive environments without degradation. |
| Low Incremental Surge Resistance | Enables tight clamping (10.3 V @ 19.4 A), reducing stress on downstream USB PHY or HDMI receiver ICs. |
| "Low Noise" Fast Response Technology | Sub-nanosecond turn-on ensures clamping occurs before sensitive interface ICs experience damaging overvoltage. |
| AEC-Q101 Qualified | Validated for automotive temperature cycling, mechanical shock, and humidity testing - suitable for under-dash and engine bay placement. |
| Soldering Compatibility | Wave and reflow solderable per J-STD-020; peak temperature rated to 260 °C for compatibility with lead-free assembly processes. |

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 clamping voltage (10.5 V @ 20.5 A); SMA (DO-214AC) package (4.5 mm × 2.7 mm) - 15% larger footprint. | Less suitable for space-constrained USB 2.0 layouts; better for higher-energy 8/20 μs surges (1500 W). | Select when higher peak power handling is prioritized over board area and capacitance. |
| TPD2E001DRYR | Two-channel, 15 pF dual-diode array in 1.6 mm × 1.6 mm USON-6; lower clamping (8.5 V @ 4 A) but limited surge rating (120 W). | Optimized for ultra-high-speed interfaces (USB 3.0, MIPI); insufficient for 19.4 A IEC 61000-4-5 surges. | Choose for multi-line, low-capacitance protection where peak current demands are below 5 A. |
Compared with SMAJ6.0A-E3/57T and TPD2E001DRYR, SMF6V0A-HM3-18 delivers optimal balance of compact DO-219AB size, 1063 pF capacitance for USB 2.0, and 19.4 A surge capability - making it the preferred choice for automotive-grade single-line ESD protection where board space and transient energy coexist as constraints.

FAQ
What is the maximum clamping voltage of the SMF6V0A-HM3-18 under standard test conditions?
The SMF6V0A-HM3-18 has a maximum clamping voltage (VC) of 10.3 V when subjected to a 10/1000 μs waveform at 19.4 A peak pulse current. This value is measured per IEC 61000-4-5 and ensures downstream 12 V tolerant ICs remain within safe operating limits during transient events. The SMF6V0A-HM3-18 achieves this performance using low incremental surge resistance and optimized junction design.
Is the SMF6V0A-HM3-18 suitable for USB 2.0 interface protection?
Yes, the SMF6V0A-HM3-18 is well-suited for USB 2.0 protection due to its 1063 pF typical junction capacitance at 0 V and 1 MHz, which introduces negligible signal distortion at 480 Mbps data rates. Its 6.0 V stand-off voltage provides adequate margin above the 5 V nominal bus voltage, and its ±30 kV IEC 61000-4-2 rating exceeds USB-IF ESD requirements. The SMF6V0A-HM3-18 is routinely deployed on D+ and D- lines in automotive and industrial USB hosts.
Does the SMF6V0A-HM3-18 meet automotive qualification standards?
Yes, the SMF6V0A-HM3-18 is AEC-Q101 qualified, having passed stress tests including temperature cycling, mechanical shock, and humidity exposure required for automotive electronic components. It operates across -65 °C to +175 °C and is rated for under-hood and cabin-mounted applications such as infotainment systems and body control modules. The SMF6V0A-HM3-18 part number reflects Vishay's automotive-grade manufacturing flow and traceability.
What is the package type and mounting compatibility of the SMF6V0A-HM3-18?
The SMF6V0A-HM3-18 uses the DO-219AB (SMF) package - a 3.9 mm × 1.9 mm × 1.08 mm surface-mount outline identical to SOD-123W in footprint and solder pad recommendations. It supports both wave and reflow soldering per J-STD-020, with peak temperature tolerance up to 260 °C. The SMF6V0A-HM3-18 is MSL level 1 and requires no dry pack or baking prior to assembly.
How does the SMF6V0A-HM3-18 compare to bidirectional TVS diodes in ESD protection?
The SMF6V0A-HM3-18 is unidirectional and optimized for DC-biased lines like USB D+ and D-, where only negative transients relative to ground require suppression. Unlike bidirectional devices, it offers lower leakage (<26 μA at 6 V) and tighter clamping (10.3 V vs. typically >12 V for bidirectional equivalents). For applications with AC-coupled or floating signals, a bidirectional variant would be needed - but the SMF6V0A-HM3-18 delivers superior performance where polarity is known and fixed.
